Dude, I can't tell you how much a love this video. The upgrade to true 1080p, 60FPS. The video was quick, yet informative, concise, and satisfying. Add the upbeat music and energy. All to showcase one of the best green lasers I've ever seen. I may sound like a shmuck right now but damn have you come a long way. 👍 I can't even wait for more laser overviews like this.

I know these laser vids are older now, but in the future, it would be interesting to test power the lasers with the meter at different distances for their strength. Just like we test bullet velocity and energy at the muzzle, 50yds, 100yds etc. That’s assuming the laser loses wattage the further you are away. (I’m just a gun channel )

[@colbyottati9921]

Your right he should

[@JAKOB1977]

its photons, so likely calculators that can reference it for you at given distances, as there aint much interacting with these massless particles. doing it crude with LPMs, would be a problematic, as you need a sensor area wide enough, and even at 7 to 10m your rad above most sensors black heatsensing spot, then you can try to beamcombine the wing ets... but meeh.. use a calculator, its photons, quite linear if you got a start reference to conclude from.

[@michaelclemons4643]

I have a 7 watt 450nm sanwu silver and a 1 watt 520 nm gatling and they are both bright but I think the 520nm is brighter

[@The177Hunter]

If your battery is too short they sell tiny magnets to stick on the ends to extend them. Meant to convert flat top batteries to button too but still work.

@@alexp7824 he's quite possibly run out of lasers to review. Suppose when a new diode appears on the market and we have something entirely new, Sanwu shall pop it in a unit and he'll review it! Hope so. Great vids.

[@superman9693]

4:50 The light intensity curve corresponds to the brightness of the dot, not the beam. Two things need to be considered here. Firstly the 555 nm max visibility shifts towards blue a bit at night and blue or violet light undergoes a thing called Rayleigh Scattering thus making the beam of the blue laser more visible. Having said that it is no wonder that your 7W 450 nm laser beam appears to be brighter than that of the 525 nm 1,2W laser.

I was thinking about selling mine. I have the 1 watt 520nm green Sanwu guardian laser. It’s bad ass for sure. No one else has anything like it. And now that they don’t sell any lasers like it on the website anymore. It’s even more valuable.

[@bitonic589]

Uhhh.... they still sell it....

[@arayan83079]

How much you want for it?

[@ikrystal9265]

Where are you XM360? Please come back, we miss you.

[@bitonic589]

They released a new diode. 2 watts of green power! Also I don't know if you got the sanwu laser 303, but if you haven't, don't. Mine broke pretty fast and other people's have too. They overdrive it heavily so it doesn't last long.

[@Saitama-_-333]

Can you help me find a good quality but inexpensive high power green laser? I want the beam to be super visible.

[@JAKOB1977]

wicked how much difference a few nanometers can create.. 520nm vs 525nm.. even at mintblue 485 vs 488.. very distinct hue difference

[@PalaciosCJ5]

I’m wanting to buy a powerful green laser. I’m considering Sanwu Striker. The two I’m considering are the 520nm 1.2 watt and the 525nm 1.8 watt. I reached out to Sanwu and was advised that the 520nmis a more durable diode with a better lifespan and their divergence are about the same. I was also advised that the 520nm has a better beam profile. The lasers will not be heavily used. Which of these two would recommend, the more powerful 1.8 watt 525nm or the 1.2 watt 520nm? Thanks for your advice.

[@thearthole]

I have the 520nm 1.2watt Challenger II and you will not be disappointed, the beam is incredible and very bright. The diode is in a can, it’s not been decanned, I think that the 525 1.8watt is decanned which could mean as you were advised that it may have a shorter life span. The 1.8watt shall also get warmer which means shorter duty cycle. I have not compared the two hit the 520nm 1.2watt for me is enough green! :(

You should do a review of the Zeus x laser that laser is quite a beast 7W and one of the biggest handheld lasers I've touched

[@Scorvet]

They do offer 2-18650 batteries for $30.00 and a single or dual charger. My question is. Will the batteries be the correct lenght?

[@Timesend]

They made an even stronger version of this green now have you got this one as well

[@TheMisterTango]

So are high power green lasers harder to maker to make than blue, thus explaining why most super high power lasers are blue? Because on just about every site I look at there are plentiful options for blue power output (1w, 1.6w, 3w, 5w, 7w) but I've almost never seen a green go over 1 or 1.6w.

[@GTraining2]

Nice video, really powerful laser

[@davidscoots2007]

do more reviews!

[@kevindondrea144]

I totally agree about the blue laser. I'm afraid to use it its so bright. Related to the batteries. My blue laser uses the 16340s but one set I bought. The + tip doesn't extend far enough to make contact with the battery in front of it. I had to use a piece of thick tinfoil bent over a couple times. I was worried about using regular foil so I found a piece of thicker stuff. Maybe twice or three times as thick. That's odd the battery is not long enough. Maybe a "punch out" from an electrical box or a coin would help.

[@LaserPictures]

You’ve progressed to the next level! A 1w+ 520 is the cutting edge of diode technology. I would be careful saying the kind of thing you did around 8 though. A 1w is still INSANELY dangerous to your and your neighbor’s vision. I know you didn’t mean it that way but not everyone knows that.

[@bitonic589]

Now they made a 2 watt one

[@johndubose1401]

Can you talk more about the lpm(power meter)? What is the name brand, and were can I get it? Thanks

[@devanh8592]

What do you do with all those lasers that you buy? I have seen you review many of them multiple times and seen that you get more than just one at a time.....do you resell them or do you actually have hundreds and hundreds of lasers layin around

[@WetaMantis]

What powerful laser should I get for 40$? And what safety glasses to accompany them for 25$? Also I would like a 2nd weaker laser for astronomy, it needs to keep my eyes accustomed to darkness without glasses (of course not pointing it at people).

[@Laserpointergreen]

Can u make a video about the black strechen chinesse 1 watt laser?

[@Sheilawisz]

Hi XM360 do you know the new models of the 303s that have usb port for the battery, instead of the traditional charger? Do you know if they are any good?Thanks!

[@The177Hunter]

I really want to ask Francis from Sanwu about a custom Challenger 2 in Damascus with a 470nm diode running at 2 watts instead of the regular 4. (I love power but I hate recharging batteries. Lol) also I wonder if there’s any ~1W orange laser diodes he could make another one with?

[@praynspray8223]

Yo XM360, can you recommend me a laser that lasts a long time and is good to use as a toy for my cat? i'm tired of constantly buying laser pointers that keep breaking on me that don't last for a while and run out very quickly, so can you recommend me one either on amazon or ebay? thanks.

[@Kmilongoo]

Very cool video. What type of protective glasses are needed for the Zeus X 7 watt 450nm laser pointer?

[@Mr-sBinotto]

From survival lasers. They sell a orange set of goggles that protect against up to the seven watt striker

[@centilion303]

The 7W blue laser has a much more solid beam, and the 1.2W green laser looks more sparkly.

[@jabc369]

Have you ever heard of the “mini laser power meter”? (Pocket size) I saw one on eBay but not sure if legit. It says 0-10.999W. Maybe you could do a review on one????

[@mussim2919]

Awesome lasers! I love it!

[@WallStreet749]

Do a burn test comparing the 7w to the 1.2w on distance witch one will light the match the furthest.

[@michelhadid]

The 7W, even though divergence Is horrible, Is still way better at burning, the Green Is just way brighter

[@SuperReeseP]

I built a 1.6-1.7W 520 and I can personally say that I see it as brighter than my 7W blue

[@sunitadhyani1013]

What diode did you use? I think nichia Ndg7475 is the brightest green diode out there which Maxes out at 1.5 watt and then dims.

[@Windows035]

i am considering buying a 1.6w green laser. i have some questions. 1. at night or day? because your eyes are sensitive to different wavelengths depending on the time of day 2. the beam was brighter or the dot was brighter? because some wavelengths make bright beams and others make bright dots thanks

Joakim Daler it’s the single mode.... you can buy magnetic spacer discs on eBay for a few dollars for a small pack and these get around the issue of shorter 18650 batteries.

[@montygraves5673]

which 18650 battery (specifically which mAh) do you recommend for the arctic spyder 3?

[@ambrosekillpack4841]

The spyder 3 I think is fine using unprotected cells. More mAh= longer runtime. Avoid anything that says anything over 3600mah because they are most assuredly a fake cell with only a fraction of the claimed capacity. If you're gonna buy an unprotected cell, I'd recommend these. www.ebay.com/itm/4pcs-3500mAh-Panasonic-SANYO-NCR18650GA-Lithium-Battery-18650-Outlasts-ncr18650b/283188689732?_trkparms=ispr%3D1&hash=item41ef5c7b44:g:g2AAAOSwXItcHbpJ&enc=AQAEAAACQBPxNw%2BVj6nta7CKEs3N0qW0gdql%2BRfdiIecosYhBDHtcpFQzJIdUudC9BnO%2F0VVvtFNL4A8XBiECr2dExYgLYGFgbFhCYwdQLF3ZwjJscr9JT7T3xi1QAcjznOovd5%2FvKnG1BSI218yKFvXf3XiK3kd9JGSHaw64LpeyUMvNLQ5zO5FrqaAAgCp5WU%2BwZec436B6%2F3ZMggxY8sNHONEHzQcYOxc7QxAPSR3tjJ%2B2BH8QpkliYjXjMF7rEYHhJCWJuU9Z9lIuifCW3R%2BF1DIuf63qj9GtaHj0%2FJdHJS%2Bn1JdwvPdtoLlWjx6p%2F3fIMq6Z7fdzsnQWH9QQ3zNiW3DjrlLsKUHIbCoRblYXNL2xTAdP1cfpcbBAtLBXf6YH9DKr4EsTpahjBmkeJ%2FiJJ6YI2McDuF9moOi0dVtFpq6FmwLI%2Fg%2Bm43YMxAJLB%2B7OZ2jsWnLrctuCb8eW5Gt%2FoMBwhREzZxnS3DR3jd8b%2F3qKiIQ3IeO07wbS8G5TVu0%2FVX4fk7WKScQ%2FA%2BQfPMc2phaN0c3%2B7mksH9%2FLAWyiS3TQzR6FpXAi2U1UhGdkNf21e7fssYeHUGrt6iAIJ%2B9EJ7FhGk1wy7Dkm7ah2Un3ISIiCHOaljdAtOa2ko7%2FHdnrrsCaYuRxnxTkDtAP2Lj4U3Tren%2FAvS7T5ljWeDzm6skVE59pX9mUiZr5T5cyNWD4e%2BEm9biWl2ckNa5km4mXMTeOUSM96xEucN2WQTduvLOE4dVY6yJz8QJf2%2BvOXamQwg8zw%3D%3D&checksum=28318868973299f99225a6414e3d8346f318bcd2d304

Hey I know this is an older post but I recently purchased a Thor H2 3w laser I’m just wondering if I would be able to use the laser outside without wearing goggles? I can’t seem to find an answer is it dangerous to look at the beam as you point it up?

[@garyoldcountry]

None of the beams are unsafe to look at pointing up, only if they reflect off an object back to your eye or of course if you point it towards your eyes. Def be careful without goggles though, I once pointed a block away and it hit a road signage and directly back into my eyes. Thankfully it was only the weak 304 laser but it taught me a lesson. :)
