I used to do laser shows for 2,000 to 5,000 people with a Merls Griot 5 watt laser , and also had an 8 watt spectra physics tube in reserve ,,, it was hooked up to a beam table , a 63 amp 3phase power supply and a fire hose to keep it cool , and was usually put into place with a forklift ,,, this new generation of stuff has gone crazy.
Bought one of these from Amazon a few years ago. Had in mind to take it with me camping because the nights are absolutely gorgeous dark with stars everywhere. Using a powerful green laser at night in those conditions is mesmerizing.
I actually got one off of eBay , it was between the second to last and last one in terms of power it was spitting out 2 watts as someone on TH-cam tested the same model. Needless to say I could light up a wood stud from across the room, light cardboard in a matter of a second and light a candle, etc. It sketched me out owning it so I got rid of it lol, these things are definitely not toys.

Came with a case, glasses, all sorts of filters you could put on the lens, battery charging cradle and etc. Yes, it could easily burn stuff. I want to say it was 5 watts….it was before the law went into effect. It was definitely a quality product and I liked that you had to hit the power button in a sequence to keep it from being accidentally turned on and so that kids couldn’t burn the house down(or melt an eye)
Have one of those (Spyder Arctic series) that stays in the safe with the pew pews because the thing is rather horrifying if you mess up with it. They still sell them but most are 1 watt or less. Only one that you can get over 1 watt is their Arctic, which is just their name for their blue (445nm) laser, that has a 2 watt version. Big difference is Wicked Lasers puts out a quality product that they are not attempting to sell as a "laser pointer" and straight up tell you the thing will make you go blind if you "F' around an find out" with it.

You should've tested how much UV light they let through. IIRC A lot of these terrible quality ones don't filter out all the UV so not only do you have the visible laser to get blinded from but also the stuff you can't see.
not UV, Infrared actually, other end of the spectrum bud. And the answer is actually usually like less than 10 milliwatts. This comes from my own test results.
99% of the lasers come from china with fake product details. the only accurate information you will more often get about them is how the product looks and what it comes with but now the actual specs. they sell kids lasers that u can use to play with pets that are actually sometimes hundreds of times more powerful than advertised which can cause you either instant eye dmg to you and your pet or eye damage over time. i think most of these lasers dont have any quality filters and almost all kids, teenagers, adults etc who buy these, they buy them for the hazard part. they want to blind tf out of people, light stuff on fire, pop balloons, just fool around with them so since pretty much nobody cares, almost nobody wont bother adding any quality filters that would protect u.
I serviced the original xerox big commercial laser printers in the 80'sThey had a large HeNe tube laser. The first thing to go is your color vision from laser damage. Some of the guys didn't follow laser safety protocols and would fail the ishihara color vision test but still had near 20/20 vision. Even low power lasers are no joke. It just takes a couple seconds to damage your vision.
4:16 you said it puts out UV ultra violet I think you meant to say IR infra red light. These 532nm DPSS use an IR pump diode that on cheap lasers does not get the proper IR filter lens.
You mentioned melting solder - could the largest laser be used to *actually* melt solder? That might be a handy (but dangerous) trick, since the laser spot could focus heat down onto a PCB to remove/resolder components. You'd just have to be careful not to burn through the board. Great video, channel, and content. Cheers!
@@cpufrost It would be interesting to make a soldering tool that uses laser energy for precise solder melting, maybe for chip removal or something. Think of the idea like a laser-cutter, but on a much smaller scale and with a modulated laser that just melts the solder without burning anything nearby. The laser could be scanned with a galvo, or something, and be modulated so that it provides _just enough_ energy to melt the solder. The entire laser solder rework head could be enclosed in a shield so that stray light doesn't [easily] escape. This might also be very useful for melting solder *paste*, since it is fairly dull and would absorb energy until it liquefies, then becomes shiny - that would require much less energy, probably. *Anything* would be better than blasting a chip with hot air or using a clumbsy iron on smd parts.
I caught a stray beam from a 48w blue diode laser cutter. Even in the split second it got me, I had 10mins of blobs to look at. Luckily no eye damage. I can tell you that it was intense and very scary! It happened while trouble shooting the laser. I took my safety glasses off to rub my eyes and at that very moment, the laser decided it was time to come alive.
I bought the last laser. It just arrived. Been testing it out and, oh my god. Instant burn marks. Not just after a second. LITTUARLY INSTANTLY BURNS. its a nice one :)
I recently bought a cheap $20 green Amazon laser which I was extremely impressed with compared to my little red pointers I've had over the years. Now I want more power! 😊
That 532 nm green laser is most likely a DPSS laser. These do not emit UV, but rather IR light. They work by using a laser diode that is actually half of their desired output frequency (i.e. double the desired wavelength; a 1064 nm diode) and striking a crystal of special material which doubles the frequency (halving the wavelength). This process is not 100% efficient, and without a proper IR filter, some IR light will also exit the aperture. It would be interesting to test that green laser again with a proper IR filter in front of it and see what the measured power difference is (i.e. how much of its output is green and how much is 1064 nm infrared). Additionally, the most likely reason that these pointers have constant laser power output for any battery voltage is that they are most likely using a boost regulator to boost the voltage to whatever the optimal forward voltage it to achieve the power output the manufacturer wanted. This keeps the output power constant until the battery gets too low to maintain this boosted voltage, at which point it cuts off.
Is it green? 8mw of green will look really bright because your eye is very sensitive to green. Even 8mw of red is pretty spicy compared to a regular 1mw laser pointer
@@RangieNZ Since it uses a rod lens to create to "chalkline" type beam even if its over 5mw your probably safe if you dont stare into it. Also humans eyes are most sensitive to green light. If sever different colorer lasers were side by side and were of equal optical power the green would seem the strongest by a long shot.
I'm loving the laser videos lately. I bought a couple lasers a year or two ago but didn't try them out much more than a few minutes because I didn't have any protective eyewear. Fast forward to today and I just started looking on Amazon but see a lot of inexpensive options with very different claims from one to the next. Ever consider testing the safety glasses for these?
used to work with lasers on targeting systems in the sir force. ours were not visible wavelength but could easily zap off grease or oil off a tool when put in the beams path. that near 5w blue one is a bit crazy, especially around $150.
@@clockworkvanhellsing372 have an example link, those are fakely marked up specs, cause no way you get a module that cheap (15W needs to combine 2 laserdiodes with beamcombiner/ pbs cube... or knife edging lasers but that does not combine easily with the use as engraver without some crazy expensive beam correction optics)
@@ZILLION4EVER Not to mention 15 watts is not going to be in the handheld or batt powered category anymore. We had a 10w at school and it was a tank probably 1.5 ft long 4 or 5" high and deep. 8lbs maybe and yeah dude wouldn't leave the power cord in the room if he had to leave. That was the giveaway that uh maybe not playtime anymore?
The danger of lasers is severe to the eyes especially animals. It is a narrow beam of light, at a very narrow range of frequencies. Normal light is spread out over the spectrum while the laser is a narrow band of energy. You can compare this mechanically as follows, the same pressure applied over a square meter for normal light while a laser being a needle point. The damage to the eyes is severe. You will not lose your sight parse but the pixels or cones and rods where it impacts will be damaged. Leading to focus issues and blind spots. Your eyes compensate a lot and this will not be apparent int he beginning. Eye protection is a must with all lasers. Dont let kids play with them. Dont point them to close objects since the reflection is still dangerous. But especially, dont use them with animals please! Their eyes are even more sensitive and they cant tell you when their eyes hurt!
Yeah really! its no exaggeration to say they are incredably dangerous for anyone under 18 (nowadays probably 25) to own. Laser light is unique in the way its focused in the eye. What seems like a safe amount of light isnt, the lens focuses into a little point on the retnia. Incoherent/chromatic light does not work that way.
We recently wanted to buy some low power UV laser pointer for precisely curing UV glue at work, but in the end decided that it was simply to dangerous to buy an invisible laser that we didn't have the capability to measure the output power of; knowing that they're usually higher than advertised.
Love the channel and the content. I am glad you discussed not pointing in or towards eyes. My son had a bully shine a Lazer pointer in his eyes as a child. He has permanent burns on his retina that have created blind spots. Needless to say I am a anti laser pointer person
Instructions unclear, cat is now on fire? Feels like a lot of these sellers haven't just crossed the line between 'fun toy' and 'industrial hazard', but have yeeted it straight into 'experimental lab equipment' territory. And it's yours for the low, low price of just $150, apparently.

I was going to flip apps and get one then wondered what my use case is going to be. Im better off missing out on this one given my intelligence level. Nice video though, definately earned a sub from me.
I'm actually in the market for a laser pointer (I'm the warehouse fork lift safety instructor, these are great to point things out three shelves up). 👍
If you are a safety instructor, it would be absolutely idiotic to get any of these because they are contrary to safety. You should get a real, ordinary laser pointer that actually emits safe levels of power.
I bought a 5 watt burning blue laser. It burns wood from across the room. It’s well into class 4, they call it class 3a and name it “blue flashlight” at least it came with a metal case, lit got show splitters and red glasses. I can imagine it would be so fucked if someone didn’t know and just wanted a “blue flashlight” then tried using it accordingly.
Green lasers (assuming diode-pumped YAG lasers, which are most common) do not leak UV light radiation, instead, they let out near-IR light radiation, which is the actual light wavelength given off by the pump diode. On top of that, there is a frequency divider crystal inside of them, which is a main part of the IR-to-green converter in the laser. So along with powerful near-IR radiation, there is also far-IR. Yikes!
The strongest one I’ve ever gotten was advertised as a “beam light” on Amazon. It pulled over 100watts from the batteries, and burned whatever I pointed it at
What happens if you aim one laser right at another laser? Do they burn each other out? Or does one win? What happens if you aim one laser at a mirror? Does the mirror absorb any heat or reflect 100%? Will a laser ruin a camera lens? Great video, greetings from Australia
Hey just an FYI as a laser enthusiast for the past good 5 years, The laser bee LPM you showed can be barely classified as a laser presence detector. The coating on the sensor head is rubbish and the meter does not have wavelength correction(this is needed because for different laser wavelengths{colors you might simply say} the sensor coating cannot be linear so it will have a different absorption value, not to mention that those so called laser power meter are not even calibrated under a single NIST certified calibration procedure. Their so called 'calibration' is the maker just checking them in comparison to an actual LPM. As you can understand that brings the error formula to: Actual LPM error + Measurement error + electronics related error( they are using just an op amp and an Arduino to read nano volts ffs)+ coating related error for all wavelengths besides the one used for the original measurement + un-shielded wire noise (reminder that we are measuring nano volts here when we're down to the dozens of mW's) = totally unreliable measurements. Hell, even china does it better at the moment with some LPMs that have recently popped up on ebay, Same construction + better electronics + actual per WL correction factors.
I love those powerful "Cleaning" Lasers. It's so satisfying to basically power wash rusted metal clean with a laser. You just better protect your eyes. Always with lasers. You never want to risk your eyesight
What batteries do you need for the final laser. Just bought one and don't know what batteries to buy... He mentioned. A 18-650 but is that the battery required?
the true mah of the garberiel 3000mah batteries under a 800ma load are only around 1500mah or that is what i got with my li-ion battery tester with these batteries.
Because the torque test channel, why not measure the torque on a Crookes Radiometer and present the findings in newton microns or so? You could even tighten a few bolts with an output shaft and enough gear reduction and time
I used to have a 15 or 45 mW green laser from Wicked Lasers. Sadly they don’t sell well made, good tolerance, hand-held pointers any more. Can you recommend a good brand, with accurate power rating claims, that sells a c. 15-50 mW green laser, please?
I had laser surgery on both eyes for torn retinas (I played hockey all my life-go figure). It was NOT a pleasant experience. When he was zapping my retina for more than a few seconds, I could feel intense heat inside my eye. I have no idea how powerful a surgical laser for retina repair is-supposedly not too powerful (they don’t want to burn a hole through your brain. I bought what was claimed to be a 20w CNC laser off eBay a few years ago, just to play around with. I didn’t trust the glasses that came with it, so I set the laser pointing at an enamel-coated frying pan, and aimed my iPhone at the target to record the action for later review. I intended to run it remotely for about a minute and then watch the video I recorded, as well as examine the frying pan. I noticed no marring at all of the frying pan surface. Perhaps I didn’t have it at the best distance to really focus the beam optimally. I didn’t notice any damage to the iPhone’s camera.
I'm confused as the video shows the focusable underwater laser as having 5 watts output but when you check them out online they all say less than 5mW? Which is correct? Thanks.
I've been itching to get a cool laser for like, 5 years now. Now I've got some money and have started investigating since a week ago. I won't be buying what I initially thought I would, this scares me now. I'd like a 200mw at best one.. I was thinking that it's awesome that the eBay ones are actually much more powerful than advertised, but I then realized I love my eyesight.
If I've learned anything from Styropyro, the answer is, "extremely." Bad IR filtering, way over spec, the works

This might also be very useful for melting solder *paste*, since it is fairly dull and would absorb energy until it liquefies, then becomes shiny - that would require much less energy, probably.
*Anything* would be better than blasting a chip with hot air or using a clumbsy iron on smd parts.
I caught a stray beam from a 48w blue diode laser cutter. Even in the split second it got me, I had 10mins of blobs to look at. Luckily no eye damage. I can tell you that it was intense and very scary! It happened while trouble shooting the laser. I took my safety glasses off to rub my eyes and at that very moment, the laser decided it was time to come alive.
Wow your very lucky my friend 😮
Can you test the glasses that are included? I was always interested are they have at least some protection, or just tinted plastic.
Viktoras K check some of Styropyro’s videos. He has tested some of the included glasses. They usually fail miserably.
This is the Friday video I was looking for.
The fact that they market them as being visible halfway across the US is just hilarious at best.
I bought the last laser. It just arrived. Been testing it out and, oh my god. Instant burn marks. Not just after a second. LITTUARLY INSTANTLY BURNS. its a nice one :)
I bought that last one to, did you buy safty glasses for yours?
I recently bought a cheap $20 green Amazon laser which I was extremely impressed with compared to my little red pointers I've had over the years. Now I want more power! 😊
That 532 nm green laser is most likely a DPSS laser. These do not emit UV, but rather IR light. They work by using a laser diode that is actually half of their desired output frequency (i.e. double the desired wavelength; a 1064 nm diode) and striking a crystal of special material which doubles the frequency (halving the wavelength). This process is not 100% efficient, and without a proper IR filter, some IR light will also exit the aperture. It would be interesting to test that green laser again with a proper IR filter in front of it and see what the measured power difference is (i.e. how much of its output is green and how much is 1064 nm infrared).
Additionally, the most likely reason that these pointers have constant laser power output for any battery voltage is that they are most likely using a boost regulator to boost the voltage to whatever the optimal forward voltage it to achieve the power output the manufacturer wanted. This keeps the output power constant until the battery gets too low to maintain this boosted voltage, at which point it cuts off.
I'd really like to know the power reality, of 'construction laser' devices. I've recently bought an "Empire eLGC" unit which it lists as "
Is it green? 8mw of green will look really bright because your eye is very sensitive to green. Even 8mw of red is pretty spicy compared to a regular 1mw laser pointer
@@gorak9000 yes, it's green.
@@RangieNZ Since it uses a rod lens to create to "chalkline" type beam even if its over 5mw your probably safe if you dont stare into it. Also humans eyes are most sensitive to green light. If sever different colorer lasers were side by side and were of equal optical power the green would seem the strongest by a long shot.
I'm loving the laser videos lately. I bought a couple lasers a year or two ago but didn't try them out much more than a few minutes because I didn't have any protective eyewear. Fast forward to today and I just started looking on Amazon but see a lot of inexpensive options with very different claims from one to the next. Ever consider testing the safety glasses for these?
That's a very good point and follow up. I can imagine there are glasses out there that are sold on lies and don't offer any protection.
Don't buy them on Amazon would be my recommendation, too high a risk of getting a fake/knockoff, buy directly from a reputable brand.
used to work with lasers on targeting systems in the sir force. ours were not visible wavelength but could easily zap off grease or oil off a tool when put in the beams path. that near 5w blue one is a bit crazy, especially around $150.
There are laser engraver modules with 15w advertised for ~20 bucks on ebay ...
@@clockworkvanhellsing372 have an example link, those are fakely marked up specs, cause no way you get a module that cheap (15W needs to combine 2 laserdiodes with beamcombiner/ pbs cube... or knife edging lasers but that does not combine easily with the use as engraver without some crazy expensive beam correction optics)
@@ZILLION4EVER Not to mention 15 watts is not going to be in the handheld or batt powered category anymore. We had a 10w at school and it was a tank probably 1.5 ft long 4 or 5" high and deep. 8lbs maybe and yeah dude wouldn't leave the power cord in the room if he had to leave. That was the giveaway that uh maybe not playtime anymore?
HELLO, in which VIDEO do you show the build of your INTEGRATING SPHERE & Light METER setup ??
The danger of lasers is severe to the eyes especially animals. It is a narrow beam of light, at a very narrow range of frequencies. Normal light is spread out over the spectrum while the laser is a narrow band of energy. You can compare this mechanically as follows, the same pressure applied over a square meter for normal light while a laser being a needle point.
The damage to the eyes is severe. You will not lose your sight parse but the pixels or cones and rods where it impacts will be damaged. Leading to focus issues and blind spots.
Your eyes compensate a lot and this will not be apparent int he beginning.
Eye protection is a must with all lasers. Dont let kids play with them. Dont point them to close objects since the reflection is still dangerous. But especially, dont use them with animals please! Their eyes are even more sensitive and they cant tell you when their eyes hurt!
I bought a high powered laser online as a kid, glad I didn’t lose my vision!
Yeah really! its no exaggeration to say they are incredably dangerous for anyone under 18 (nowadays probably 25) to own. Laser light is unique in the way its focused in the eye. What seems like a safe amount of light isnt, the lens focuses into a little point on the retnia. Incoherent/chromatic light does not work that way.
We recently wanted to buy some low power UV laser pointer for precisely curing UV glue at work, but in the end decided that it was simply to dangerous to buy an invisible laser that we didn't have the capability to measure the output power of; knowing that they're usually higher than advertised.
They make UV lights that will do the job and not risk someone going blind. Just don't point it at your skin and you should be good.
Ok, but what about the shark mounted variety?
fun fact, the first item ever actually sold on ebay was a broken laser pointer.
Love the channel and the content. I am glad you discussed not pointing in or towards eyes. My son had a bully shine a Lazer pointer in his eyes as a child. He has permanent burns on his retina that have created blind spots. Needless to say I am a anti laser pointer person
i think its only fair the bully is found and given the same treatment.
@@_AndromedaGalaxy_ I think a more permanent fix is required. Like a lifetime garnishment of wages as reparations for the blinding.
You say "sketchy", I say FUN! 😂
Thanks buddy. I will order the 150 dollar model today.
Had me in stitches at one point. Good stuff
I hope these could be safe to use. Do check for eye protection before having it.. You did a great review.💛
Instructions unclear, cat is now on fire?
Feels like a lot of these sellers haven't just crossed the line between 'fun toy' and 'industrial hazard', but have yeeted it straight into 'experimental lab equipment' territory. And it's yours for the low, low price of just $150, apparently.
Holy moly, part of me wants to order this and the othe part of me wants my kids to keep their sight.
great reviews! my eyes hurt now
This would have been helpful knowledge 4 weeks ago.
I had a balloon that I needed to eliminate but was too high up in the sky for me to reach with the items that I have available.
Pus it's a hell of a lot cheaper than a sidewinder missile.
Signed,

Plus it's made by his employers......
simply attach to a telescope for a better visual of it in action.
I was going to flip apps and get one then wondered what my use case is going to be. Im better off missing out on this one given my intelligence level. Nice video though, definately earned a sub from me.
I'm actually in the market for a laser pointer (I'm the warehouse fork lift safety instructor, these are great to point things out three shelves up). 👍
Somebody else suggested IR thermometers, since those don't go overboard.
If you are a safety instructor, it would be absolutely idiotic to get any of these because they are contrary to safety. You should get a real, ordinary laser pointer that actually emits safe levels of power.
Go to a pet store
That last one is straight up a weapon....
I was wanting to see the palm tree burst into flames a little bit
I’d love to see some UV flashlight comparisons.
I bought a 5 watt burning blue laser. It burns wood from across the room. It’s well into class 4, they call it class 3a and name it “blue flashlight” at least it came with a metal case, lit got show splitters and red glasses. I can imagine it would be so fucked if someone didn’t know and just wanted a “blue flashlight” then tried using it accordingly.
Can you test dispersion? How big are the dots at 100m?
The dots used to be 30 cm, but now i cant see anything at all.
Great Video! Any chance you could share the battery make/model used for the "beast" laser? Thanks!
Any 18650 makes the same juice it in
@@TorqueTestChannel thanks just ordered mine and I've been seeing alot of cheapo batteries to be careful of on reddit
Pro tip, do NOT point lasers at the sky.
Ferb, I know what we're gonna do today!
How else do we signal the Martians?
Just remove the tin foil hat @@SegwayBossk
Aside from airplanes, why not? We don't have planes that fly over here so I can't see the issue.
What color laser produces the most torque though?
green
@@_AndromedaGalaxy_ Howdy neighbor! Thanks for the info. Sorry I'm kinda busy now but I'll see you in about 4 to 5B yrs
have you tested the ir temp gun laser? fluke is pretty darm bright.
Try the WickedLasers 3W (?) white/blue laser and see if it keeps its claims.
WickedLasers got in trouble and doesn’t sell handheld lasers
@@TheOfficialOriginalChad Too powerful I guess?
Jeebus - that's cool and crazy at the same time...
Green lasers (assuming diode-pumped YAG lasers, which are most common) do not leak UV light radiation, instead, they let out near-IR light radiation, which is the actual light wavelength given off by the pump diode. On top of that, there is a frequency divider crystal inside of them, which is a main part of the IR-to-green converter in the laser. So along with powerful near-IR radiation, there is also far-IR. Yikes!
What would a practical use be for these considering the danger to your vision when using.
Smoking weed
Domestic terrorism is about all I can think of
@@jeremymcadam7400 kind of my point for posing the question as it seems there is no practical use for these.
Nuts. Can't seem to think of a actual real world use for these.
The strongest one I’ve ever gotten was advertised as a “beam light” on Amazon. It pulled over 100watts from the batteries, and burned whatever I pointed it at
Real quick… is the tody actually worth the money?
Styropyro has done some good videos on ebay products
Regarding the TopLaser, how effective is it at burning Iranian objects at altitude? Asking for a Ukrainian friend…
4:15 No sir it does not give off UV but powerful IR light and it is common issue with green dpss lasers!
@4:14 , you said it puts out a ton of UV light as well, that's incorrect, it's infra red light that's the by product of 532nm diode pumped lasers.
What happens if you aim one laser right at another laser? Do they burn each other out? Or does one win? What happens if you aim one laser at a mirror? Does the mirror absorb any heat or reflect 100%? Will a laser ruin a camera lens? Great video, greetings from Australia
Dude you should find something other than that palm tree to point at. They turn into a torch really fast once they go off.
This is making me wonder how powerful the Lazer leveler we use at work
I sure wish my old HeNe 1mW laser tubes from the 80's burned holes in wood like that lol
Fun fact toads and frogs will attempt to attack a Lazer dot just like a cat
Hello. It was a very good video. Can you tell me the name of the last laser?
Could you please post the link to that calculöator to see how much it damages and everything like that
Uhhhh was looking into buying one.... after this, i think im good.
10:10 "The world's best/worst soldering iron."
The fact that the company who made the immediately broken laser was called "som good" I think is being criminally overlooked
what happens, if i hold this top laser to a guy breaking in my house? will he be instantly blind and unable to do anything??
that is a great question, i would love to see the idea tested 😂
Hey just an FYI as a laser enthusiast for the past good 5 years, The laser bee LPM you showed can be barely classified as a laser presence detector. The coating on the sensor head is rubbish and the meter does not have wavelength correction(this is needed because for different laser wavelengths{colors you might simply say} the sensor coating cannot be linear so it will have a different absorption value, not to mention that those so called laser power meter are not even calibrated under a single NIST certified calibration procedure. Their so called 'calibration' is the maker just checking them in comparison to an actual LPM. As you can understand that brings the error formula to: Actual LPM error + Measurement error + electronics related error( they are using just an op amp and an Arduino to read nano volts ffs)+ coating related error for all wavelengths besides the one used for the original measurement + un-shielded wire noise (reminder that we are measuring nano volts here when we're down to the dozens of mW's) = totally unreliable measurements. Hell, even china does it better at the moment with some LPMs that have recently popped up on ebay, Same construction + better electronics + actual per WL correction factors.
I love those powerful "Cleaning" Lasers. It's so satisfying to basically power wash rusted metal clean with a laser. You just better protect your eyes. Always with lasers. You never want to risk your eyesight
What batteries do you need for the final laser. Just bought one and don't know what batteries to buy... He mentioned. A 18-650 but is that the battery required?
So are these safe say you were just pointing into the sky at stars? Do you still need glasses for that?
Could you torque test diffrent brands of torx bit sockets? Gearwrench, icon, snapon.
1:32 😂whiskers is in trouble 😂🤣
the true mah of the garberiel 3000mah batteries under a 800ma load are only around 1500mah or that is what i got with my li-ion battery tester with these batteries.
i always preferred LG MJ1
@@_AndromedaGalaxy_ i always use samsung 25r's but they are overkill in a flashlight. so i buy and test cheap batteries for my flashlights.
What’s taking you guys so long to post the new Bauer Brushless High Torque that popped up on the website this morning?
Haha I know right? Our store doesnt have stock quite yet
Seems like the perfect way to kill summer time flies if there were some way to not torch my house doing it
Because the torque test channel, why not measure the torque on a Crookes Radiometer and present the findings in newton microns or so? You could even tighten a few bolts with an output shaft and enough gear reduction and time
I used to have a 15 or 45 mW green laser from Wicked Lasers. Sadly they don’t sell well made, good tolerance, hand-held pointers any more. Can you recommend a good brand, with accurate power rating claims, that sells a c. 15-50 mW green laser, please?
Finally F16 grade lasers
I had laser surgery on both eyes for torn retinas (I played hockey all my life-go figure). It was NOT a pleasant experience. When he was zapping my retina for more than a few seconds, I could feel intense heat inside my eye. I have no idea how powerful a surgical laser for retina repair is-supposedly not too powerful (they don’t want to burn a hole through your brain.
I bought what was claimed to be a 20w CNC laser off eBay a few years ago, just to play around with. I didn’t trust the glasses that came with it, so I set the laser pointing at an enamel-coated frying pan, and aimed my iPhone at the target to record the action for later review. I intended to run it remotely for about a minute and then watch the video I recorded, as well as examine the frying pan. I noticed no marring at all of the frying pan surface. Perhaps I didn’t have it at the best distance to really focus the beam optimally. I didn’t notice any damage to the iPhone’s camera.
Are there any good red lasers from aliexpress, I am looking sometihgn in 200-500mW and about 30$.!
I'm confused as the video shows the focusable underwater laser as having 5 watts output but when you check them out online they all say less than 5mW? Which is correct? Thanks.
Great video!
I've been itching to get a cool laser for like, 5 years now. Now I've got some money and have started investigating since a week ago.
I won't be buying what I initially thought I would, this scares me now. I'd like a 200mw at best one.. I was thinking that it's awesome that the eBay ones are actually much more powerful than advertised, but I then realized I love my eyesight.
4:15 i think he means IR light instead of UV
My Friday morning is now complete.
Wouldnt you have $hit if that palm tree burst into flame....lol.Great job TTC
