In this video I'm reviewing the UKing ZQ-J12 1 watt 638nm red laser pointer. It's sold by Banggood.com, has multiple modes and a built-in focus feature. Be sure to use safety glasses and be careful where you aim it!

One thing I forgot to mention; Banggood lists the power for this laser as follows:
1mw = 1 watt
5mw = 3 watt
This is likely to get around customs laws. What I have here is the 1mw model, which is really the 1 watt model
Yo bro buy a 200mw laser any colour you want from this website called kaidomain and do a review on it! One of the very few websites which will give you a laser that's true to its MW and cheap!
Thank you so much for linking good safety glasses. Its so important that people are aware.
No problem, definitely makes a big difference
damn I've never seen a 638m that was over now than like 5mw😂
Very bright beam for a red laser. Nice video 👍
I need to tell u that all highpower red laser have horrible beam divergence... its just the nature of the diode. its a line and not a dot. U need a beam extender that can fatten up the beam and correct it.
Ya, I've noticed that too, but none as poor as this one
Andreas Tzimboukakis that's very true, I bought the Sanwu x3 Beam Expander and it beautifully corrects the beam profile. But you need to check first if your laser host has matching M*PItch thread in order to fit it.
yes rob. I have a 1W sanwu red laser and it has horrible divergence without the expander. At higher wats all laser starts having worse divergence so a beam expander is pretty much essential if u care about having a nice beam.
xm360 my sanwu 1w 639nm have even worse divergence than that so its perfectly normal.
Have you reviewed your LPM?
afterall it is a private made hobby grade TIC-meter, and I recall some of the admins on Laser pointer forums got like +15% inaccuracy errors on some of there laserbee-units some years back, but I have not been ajour if it was a fluke or it got sorted or the reason, but what are your impression do you get reading that are way off from one to the next and do you have lasers that you exactly know the power watt effect off and you can use a semi reference??. as I saw reading up at 681mW at 8:55 and next reading is more then -10% lower.
This doesnt have to be bad sign, as lasers can actually be quite different from one reading to the next, but its more the overshoot that seems weird,
whats your view on this meter, I know you dont have a reference class LPM to hold it up to, but often you can sense it simply from multiple reading if there is big variations.
anyway did you conclude if it was Mitsubishi PL73 or Occlaro HL63193 they have fitted? canned HL63 or decanned diode.MP73 ?
Thx for your video, and particularly the LPM testing.
You raise very good questions! I did a video of the LPM a while back, but it is a bit dated:
th-cam.com/video/XGpIaJA3rZ0/w-d-xo.html
I have always enjoyed the unit and trusted its results. I have taken several commonly tested lasers with plenty of readings on LPF, and my Laserbee always seems to be spot on with the data. And lasers that I tested a year ago will still show the same power reading today. I use the Laserbee A, which has been discontinued for an upgraded model. As for the diode here, I don't do a whole lot of teardowns (mostly because I'm awful at putting lasers back together) so I can't definitively confirm the diode
YAS I love the lazer vids
Great video!
I was wondering if u can tell me .
Can you ignite fire work with a laser 303?
De Gaming Guy no
Yes
Have you ever planned on buying a yellow laser? Or are they just too rare :P
Actually might be getting one to review in the following month!
Can i please have one of your less favorite laser pointer to me i subscribed to you bucuse your show us how the lasers point and work and you are a real kind person and you tell us everything that what the laser does and the warnings. #YOURTHEBEST
And #YOURTHELASERPOINTERLORD
absolutely not he would go to jail for that. Buy your own laser
Play GTA bro
Addicted to you laser videos :D
You have an awesome backyard
Thanks!
@@XM360 you ever actually use that boat? Lol, if I lived on a river I’d be out there every day.
I've always wondered about these. Generally, just about all high power multi mode diodes will produce this rectangular spot and have wider divergence. Some have more than others. But reds are the worst... not that they're cheap or anything but just the nature of these diodes. Sometimes you gotta lower your expectations. Your single mode (lower power) diodes are going to give you that quintessential Dot most expect. Nonetheless, nice review! Thx😉
Ya, I've noticed this with many of my reds, but never this bad!
Good review
Thanks man
Nice viedo 👍 I subbed 4 years ago and liked every viedo
Why don't you do a video on which is the best one like military vs the 303 laser pen? You videos are awesome but the way
Great idea, I'll probably do it soon!
Another great laser review!
Thanks!!
Someone please link me to a nice green laser, that has a nice tight beam and that I can see the whole beam, I’ve been looking everywhere and I don’t wanna buy a junk one or a expensive junk one
Wow, I bought a laser today. I'm glad you're still uploading laser videos. Hats off to you.
what is the most powerful laser I can't buy.
That line between through that dot. That’s the laser cavity, that’s the nature of the diode emitter
I ve a 637 nm Viper from Dragonlasers with 50 mW. It has a round beamshape and extremly low divergence - reaches far distances, although it has little power (no burning possible). In the darknes you can see the Beam satisfactory good. My 200mW 650 nm is a bit worse to see even though 4 times the power.
I know how to build my own unit using HL63283HD 1.2W 638nm
OX-BX8 review please
That is one strong laser
Honestly looks like a wannabe Sanwu Guardian.
That’s the first thing I noticed!
638 is the best red
10/10
All these lasers use laser 303 diodes...I get the same power with my laser 303 red...if you really want a 1w laser but the blue Chinese galting laser
I am kinda interested in these. The divergence looks worse then some of the high powered 445nm though. It might do well with a 3x expander to put a cap on the divergence. If the 1w is actually 600 any guess as to what the 3w model might actually be?
When testing with the LPM would it make much difference if the batteries weren't fully charged? Thanks
Most of the batteries I get are skywolf 16340s
how does a 1w laser run off of only one single 16340?
Xm360 i have a 1 milli watt laser but it can burn
3watt is what u need bud
I just ordered my sdlaser 303
Sean Horvath me 2 but than the normal one :)
De Gaming Guy ya I might be starting a collection
Nice
I've got a violet, red, and green laser 301. Can't beat it for the price. They all burn very well.
well the box even said "1mW" .. but that is obviously not 1 mW .. looks half-watt. but yeah, a laser without a key of 1 watt would be subject to being tossed at customs due to the FDA/ILDA regs, especially since its calling itself a "laser pointer". Granted that it is lacking a compliant warning label could get it pulled as is. But under-rating is becoming a fairly common way to skirting the import regs, since technically you have to file a variance to import anything over 5 mW. oh.. you did a power measurement... yeah seems about right... but yeah, all our laser imports require full appropriate declaration on a FDA Form 2877 (OMB # 0910-025) including all documentation to support classification and compliance to control rules. But yeah, looks like a reject diode from the manufacture of laser products like ours. *shrugs*
