Everyone interested in this should know that lasers are extremely dangerous, in that a person's eyesight can be permanently damaged by a focused beam of laser light of even a fraction of a watt. Even a brief glint off a shiny object can blind a person. Researchers in the field always wear protective goggles for this reason. These things should not be used as toys. I know because I worked in the field. Our rule was this: if you can see the beam, you are at risk. Our joke was: Do not stare at beam with remaining eye!
Very great comment ^
Yeah that is the crappy part about powerful "La-sers". You slip one time with the safety glasses, and boom, your blind. That is no fun.
I did a lot of service work for a company that produces communication lasers. They always let me dig through their electronics waste bins. I could have had all the power supplies and laser diodes I wanted. However You just can't show it off Willy-nilly . That's probably why XM360 made his awesome TH-cam channel.
O shut up safety nut. Not take my money!!
Plasmatony in my line of work, invisible infrared lasers are far more dangerous.
BRAVO! I guess I got angry before I read any of the more calm warnings.
If they have lasers this powerful available to the general public, imagine the stuff that's classified.
Lasers are openly displayed and documented...Google them! I've worked on a top secret project but it wasn't lasers...
The general public can buy like 50+ Watt laser tubes albeit c02 tubes so you cannot see the ir laser beam they are mighty powerful they are essentially the laser tubes you would find in a c02 laser cutter machine :)
I don't have to imagine classified's lasers' power, I know. Unfortunately I can't share this information publicly, but just trust that if I said what they can do, you would say "No. That's impossible. Lasers can't do that!" Think of it this way: multiply your most crazy optimistic pie-in-the-sky fantasy by 10X. Lasers aren't just for pointers any more. Now they can melt a desert into a glass-art in a micro-second. "Building? What building? Why it was just there a second ago." Now, back to more manageable 1W to 5W: Hedge trimming. Think about it, you don't need that pole cutter. Use the laser. So long as you've got a hose nearby, topiary will become commonplace.
There's public info on a "Low Power" Boeing air defense laser. Rated at only 5000 watts.
So imagine what it is classified as "High Power".
@@saltysteel3996 Yeah, like I mentioned, I know some of the real stuff out there nobody talks about, can talk about. 5000 watts won't do what I'm talking about. 5000 watts will cut 1" steel. What I'm talking about eclipses that more than an order of magnitude. More than two. Imagine the amount of power required to punch through 6" of concrete and you aren't even close yet. It's best not to think about it in terms of wattage. That just constrains the imagination. For wattage, just think "many, many, many watts" & don't fret about how that is done.
Thank you for this review. I ordered one with the expander a few days ago, and with the multi-mode function.
Appreciate you emphasizing the mandatory "off" time. Many people have ignored this resulting in a destroyed laser.
Styropyro says hold my beer

If he got this...
He would have taken it and pumped the power way up
Styro would hulk this out with witty banter.
@rvidal0001 10w diodes are only available in cnc cutters and engravers...you can buy 15w ones now but nothing handheld is above 7w at this time due to the heat and power supply. You could buy a 10w and driver but it would quickly burn out without proper cooling. This 7w has a very short cycle of 60 seconds on/off. CNC lasers have fans and cooling fins etc and can only be on a couple three minutes or so. My buddy got one for his XY CNC and it's maximum run time is 5 minutes and even then it's literature said the diode could fail and recommends projects that can be run in only 3 minutes. There are sophisticated cooling options but they take up whole long tables and are impractical.
rvidal0001 he recently got a 100W diode
Thank you for the detailed content , nicely done thanks for posting !
I have their 3 watt Silver Series in 445nm and that’s pretty amazing and quite scary at times to use. Never ceases to amaze but 7 watts! Incredible! Great review by the way. :)
Thanks!!
@@XM360 when you going to stop calling them "pointers"?
I just read your review at the forum and now axintentaly I came up to your video, wow, nice video by the way
Glad you enjoyed!
Thanks for the mention man! Yeah, my diode died, i did use it for about 10 minutes constant on when it was -2c outside. Don’t copy me, lol.
(dying inside while typing that comment)
Did you get a new diode?
Pheonix19581 No, i paid an extra $60 and swapped it for a 4.7W 465nm laser instead
Kaskobi lol I’m a big fan of your vids and you make me happy 😊
How long did the diode worked before? Do you think, that the diode died because of an inner overheat? Told about the little high-energy handhelts, that there cannot happen enough cooling, therefore die fast. But the bigger like such in the video and for such a price... 🤔😐 My god... :/
It would make sense that the reason it unscrews in the middle is just for ease of manufacturing. As a CNC turner, I can assure you boring a long thin stainless steel tube isn’t easy, haf the length and you’ve saved a lot of hassle. Nice videos! 👍
Let's also mention this unit will blind your enemies permanently in 2 tenths of a second. Add a star adapter and you can blind 50 of your enemies in 2 tenths of a second.
Yess I want one
These things probably blind more idiots holding them then enemies lmao
@@juliogonzo2718 Like a grenade with a label "Pick me up" lmao,

Thank you for great review
few days back i encountered videos showing striking lasers on airplanes are bad, now I'm getting this on my feed
interesting
Wow....Scary powerful is cool and I'm in awe of this, but I'd like to see you get your hands on and review more exotic wavelengths. I really want to see a 488nm 😊
Oh believe me, it's on my wishlist!!
I've got a 470nm 5 watt Sanwu Striker, and I can definitely say these lasers are weapons, every time I turn it on I am absolutely astounded. You can't go wrong with Sanwu.
I ordered this one at 7w single mode. Came to 475 with batteries and charger. I have a 1.5w and a 5W I built but the 5W driver only gets it up to about 3.5w, they both burn nicely and blow my mind they can be hand held. Waiting for it in the mail, they emailed me they take 5 to 10 days to ready or make the laser to order then shipping...so excited!
@@brandonbentley8532 what's the difference between single and multi mode?
@@tomfoil5590 There are different modes to the laser: like high power, low power, strobe, SOS, and I think more. Single mode is just off and on.
@@tomfoil5590 single mode is good multi mode bad
@@Shonade_Malik Ohh you're talking about operation mode, thought he was talking about laser diodes
I have one of these and with the beam expander i can focus it into a dot at over 100 feet away so it just depends on the person who builds it
These class 4 lasers are exceptionally powerful. A single small mistake WILL result in permenant eye damage or blindness. I always use a heavy tripod and don't causally wave the laser around. I also prefer a good beam stop like a cliff or a tree and one must always do a proper aircraft check to insure no aircraft are in the air near where you are poining the beam. They are amazing tools and I love class 4 lasers of various wavelengths. Use to only have the 445nm burning lasers now were seeing 470 which is just awesome! Always wear properly rated safety goggles when setting up. As XM360 said these things are no joke!
Even worse, your eye can literally catch on fire and burn from the inside...
At what range can it blind instantly?
Great review, convinced me to buy my own 7W Striker! But my experience has been different to yours. With the Beam Expander I am getting a nice, more or less circular dot at 500 yards plus, nothing like the line you were getting on your rock wall at around 150 feet. I guess you know the beam expander is adjustable? It has an adjustable thread in the middle. If you unscrew the thread all the way out, then attach it to the laser and steadily screw the adjustment back in, you should get a highly concentrated spot, no trace of that power sapping divergent line as seen in your video. Of course there may be some variation between individual Striker lasers which could account for your result. My only minor gripe with this laser is that the focus adjustment on the front of the host is a bit sharp and somewhat painful on the fingers. Otherwise this is an amazing piece of technology and every laser enthusiast needs one! OF COURSE IT IS ABSOLUTELY ESSENTIAL THAT ANYONE USING A LASER OF ANY POWER USE SAFETY GLASSES AND NEVER EVER POINT THE LASER AT ANY LIVING CREATURE OR AIRCRAFT, THIS IS NOT A TOY AND CAN CAUSE INSTANT BLINDNESS!!
Mines in the mail as I type! I have a 1.5w blue and a 5W blue...expecting this 7w or 7.5 actually to blow my mind. Have protective glasses ordered with higher OD rating...I'm like a kid waiting for a lightsaber to come. Been into lasers since the 80s! I'm 44 and giddy as a kid on christmas! I did not order the beam expander but will after reading your comment.
@@brandonbentley8532 definitely get the beam expander. It works really well and adds a lot to the enjoyment of the laser!
Not only blindness this thing can also easily burn your skin
With the beam expander it looks like a real light saber.
Just got this laser and I’m in love!!!
How far away can it light a match?
Great review. At what point...how far away, will it not burn anything
If I can't fill a swimming pool with pop corn kernels and pop them all from space I'm not interested.
It was 1985 "Real Genius", except it was that they filled a corrupt professor's house with popcorn and used his own airborne LASER system to pop the kernels (with him still in the house(?), as I recall. It might have been the professor's TA in the house at the time).

All you need is a contingent phase tracking system and a big mirror and you could vaporize a target from space.
@@komradekat3557 hahahaha and what are dew's?
@@anthalas9 what is a conjugate phase mirror? or phase tracking?
I ordered this laser a couple of years ago directly from Sanwu. I was extremely impressed with the quality of this laser. I still play with it all the time! It can burn stuff like you wouldn't believe! It could easily be used for personal protection as it will permanently blind you in a fraction of a second. A little pricey but money well spent. Overall I give this Laser 10 out of 10.
What is the price of this laser?

Can you please message me back on this. Will it start a fire from let's say, 16 - 20 feet away?
Where did you order from plz
Great vids do you know what lens comes stock with the laser?
Curious question you always need to wear the red glasses do you use this? Or is it only when there’s a chance of it bouncing off like a shiny object or something like that. I’ve never had one before so I’m unsure, and everybody around me need to wear glasses also. So if I’m just outside burning like leaves or cardboard or starting a campfire do I still need to wear the glasses whatever are useless. Thanks

I recommend the 800mW 532nm PLE PRO from jetlasers that will go over 1 watt
Strypo operates laser 10X the intensity in his room lol
Hey do a review on a 1W green laser, I’m in the market and would love to see you review one you think is worth it.
Finally an excelent quality laser featured on this channel, about time! Cheers
Dude your mind is in the right place
i just got mine. its brightness is equal parts terrifying and badass.
Hi can you plz tell me how to switch out the lense?
How far away can it burn a paper or a match?
Yikes, I forsee alot of little brothers growing up blind from sneaking into bedrooms to snoop through stuff. I suppose suggesting storing it without the batteries in it would also be wise. How is it for hare cuts, Doc?
I have a survival laser S4X host that's ready to be used. My Nubm44-v2 laser diode came in today so I'm just waiting on my SXD 4.5A driver
I bought myself a laser 303 it is really good you got to use it wisely
Yeah the 303 lasers are like 14$ on ebay. They wont burn anything.at least my green one wouldnt..
Blue is extremely dangerous. A 7watt handheld is wicked dangerous... its too easy to blind yourself or others with it.
Even looking at my 303 green on my wall hurts eyes
Interesting stuff. I just got a 3w 450nm and am being very cautious using it. This one looks like a potential future purchase but I want to learn a bit more about them and safe use of them. Cheers!
3w! Very cool, I first got a 1.5w blue then 5W blue...ordered this 7w! My 1.5w is a burner and emgraver. Be careful with that 3w friend...serious laser!
Did you try it yet?
I think its engineered to expand the width at distance,because you could imagine the nut cases aiming at a pilot of a plane what could happen.Or in Australia when in the summer time it is very hot and very dry,we have bush fires that ass holes set on fire on purpose.
As you know you could slim the beam down really well using spacial filtration. but It would take up some space,
Visible blue beam in daylight, that's insane.. Nice review!
Nice review. It's too bad that the laser goes wide too fast.
if you get the 7.5w laser multi operational mode, do you have 7 watts of raw power, still have the 6.5w output or 7.5w advertised?
Absolute beast I want it!!
They have the beam expander to remedy that. Styropyro uses the same diodes, all diodes have this it's just a matter of using the right lenses to elevate and direct the beam.
Just keep in mind watching this laser displayed on a wall will blind you.Wear laser glasses
Looks cool! I’m the guy that bought the nano s
Glad you like it!
holy hell that thing is awesome
Besides a stainless steel casting what would you suggest for a casing with that type of magnitude of power
Looks like a Light Saber. :)
I’m afraid just watching this video without safety glasses holy crap.

I'm new at lasers as i just got my first 303's but have been interested in them for ages. What keeps me from buying the 7W Striker is the price, the shape of the beam at long distances (even with the expander) and the stupidity of people as you can be sure you'll be in trouble over here even if you just aim it at the sky avoiding planes... I'll probably buy one eventually, just hope they don't discontinue it for some reason.
Can these laser be used to protect themselves from certain situation under attacks or emergency situation?
Yes. Ita good for defense for sure especially a shooter
Wooohooooo! Not Your Father's Mountain Ale. That's some pretty good stuff....
You know it!
Great review!! I’ve recently brought a Zeus 7 watt and I’ve trying to work out how far the beam is visible.
Do you know ?
I guess about 50-60 KM
Nice video, I was into lasers a few years ago and there were no reviews on TH-cam (only one website-the LPF). great work! I really want a 300+mw green, can you recommend one? I don't know if laser btb or Jetlasers are still reliable... I might check LPF if I can remember my PW lol.
Thanks a lot! Tough for me to recommend one only because high-powered greens are one of the only things I haven't gotten my hands on yet!
+XM360 I feel ya, it seems like the price on the greens actually went up! I just checked around real quick... Too bad Laser btb apparently fell apart, they had a popular 300mw with IR filter for around $250(+or-).
That's the kind of laser that makes you want to dress in your Jedi wardrobe, drop some dry ice in the bucket, and pull out the Kodak :D
And accidentally blind all your friends...
Feel ya on that one. Hopefully you're smart enough to give them laser glasses and do it outside.
What's a Kodak?
Those high power 445nm multimode diodes are horrible with fast axis divergence. Beam expanders help a lot. Camera zoom lenses work well if you can fit one to the laser. Little loss but still powerful! I actually use mine as a thermite igniter. Thermite is difficult to ignite, not with a 445 or even 405nm laser. 1W is all that's needed if close and focused, 4+W is needed to ignite from a reasonable distance when focused to infinity.
Chris Barth why am I thinking 911?
If you used two of those beam focusing attachments would it focus even better?
I love your videos ...now it's time to make a video with Zeus 7 watt haha
This is a great piece of electronics. I question as to what was the reason you bought it for? OK, It looks cool and it lights things on fire and it's got a great looking beam. Here is the top question of the day. What are you going to do with it? It cost you money. Is it just one of those things your glad you bought it just because you wanted it.
In a way you are right. Not many practical uses I have for it; simply an addition to my laser collection & hobby
Disclosure was made, in the video. It was Given to him in exchange for an honest review.
Do you need license in the USA to use and or buy them?
Here in Sweden, if they go over a certain "strength", a buyer would need a license..
Question: With this and many other lasers being so dangerous to view without quality safety glasses how much danger does this laser pose to anyone near me when I point it up into the sky or just using in any conditions? Do onlookers also need safety glasses?
Can you recorgnize the difference between a 445nm Laser and a 455nm Laser?
Not technically in the general color spectrum. The power output is more critical.
Can you burn a gas station from a security distance with one of these? 😁😁💥🔥

Could of just said 70mW to make it so much easier to understand
So this can be used to laser point the ISS in space and see it on live feed?
It has already been done with less powerful blue laser, there's a photo on here somewhere, saw it some time ago. They had to use some special robotic arm and complex calculations to be able to adjust for the movement of the iis and hold it pointed precisely at it for some short time.
Yep, and then spend a year in jail.
@@flagship1701e try 20
I've thought about it before. Lol! Yes, very good chance it could be seen from the live view cam.
No jail or legal issues. Beams divergence would be a few miles wide at 300miles but there will still be enough photons available for the sensor to register. Just make sure it's not an aircraft!
@David M Yes, the beam width and height will
keep the same ratio with distance. Need a single mode diode for a better beam but they still diverge.
fascinating that this made it through customs. Extremely dangerous to the eye

When you think about it just a few hundred years ago in New England (or anywhere else in the world) this device would have branded you as a sorcerer and probably burned at the stake. Nowadays being able to burn things at a distance is no longer magic. It is really fun, but no big deal. If someone asks you, "are you a wizard?", just smile and say yes.
Rascal77s you would like exurb1a's video "10,000 more years of the scientific method"
Robert the Robot thank. Great vid. Unfortunately there's been a disturbing trend of labeling science and math as racist. Maybe we will be chucking spears at each other in 10000 years.
That's why you just shine the laser in their eyes and stop them from burning you hahaha
Burned at the stake? Not if you burn them first lol
Nobody will brand you a wizard because lasers didn't exist in the late 1600s. They're almost ubiquitous today, though. Every checkout lane, every dvd player, CD player, etc... has one. Being able to burn things at a distance was never magic because it wasn't even possible before the invention of the laser in the mid-20th century, and by then, people were well acquainted with radios, rockets, television, atomic bombs, etc... I'm sure the first consumer lasers were quite a hit at parties, but nobody ever invoked any mystical quality as long as they've been around.
That laser is incredibly cool, but seriously, what can you actually do with it apart from playing?

BadRonald1 it must suck to be stupid? Consult your favorite astrophysicist and get back with me! A red 5mW will hit the moon, our puny eyes can’t seen it. Yada yada some beam expansion.

What is the use of all these very expensive lasers???
Praful Thaker good question. I have had an Arctic Spyder III for a few years now and almost never use it. You get over the mystique in like 2 weeks. I occasionally use it to burn spiders I find in my house, but only if it's on a light colored or non flammable surface. Lot of money wasted for that.
Praful Thaker irritating simple folk.
Praful Thaker scientific curiodity, fun, and in an emergency for various uses.
If you are an amateur astronomer and own a telescope a laser (green in particular) is an excellent tool for pointing out stars planets and other heavenly bodies.
There are some experiments you can use high lasers for. You can ignite stuff that is in a sealed glass container, like a vacuum chamber or a still, or engrave stuff into polymers.
Also, its not expensive. its only 350$. For a company or a group of researchers thats peanuts, not even worth mentioning. Its a lot for someone to light a couple matches at home and then put the thing on the shelf, but its not a lot for someone actually needing it for something.
What's the difference between single and multi operation modes? It gives these as options when you configure your laser on their website.
Beautiful.
