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!

If they have lasers this powerful available to the general public, imagine the stuff that's classified.

Thank you for this review. I ordered one with the expander a few days ago, and with the multi-mode function.

Styropyro says hold my beer

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. :)

Finally you got it! Congrats bro :)

Thank you for the detailed content , nicely done thanks for posting !

I just read your review at the forum and now axintentaly I came up to your video, wow, nice video by the way

Appreciate you emphasizing the mandatory "off" time. Many people have ignored this resulting in a destroyed laser.

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.

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.

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! 👍

Looks like a Lightsaber, we're getting close

Excellent review!

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

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.

Nice for lighting the grill.

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!

Nice video, Sanwu definitely make some quality stuff.

Thanks for the review! The diode they use is actually a Nichia NUBM08 with the gball removed (open can).

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 😊

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.

Keep on those great vids

Great review, thanks for sharing!! 👍

My jaw literally dropped and ran off what a absolute monster 😍😍😍😍😍😍😍😍😍

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!!

Can you recorgnize the difference between a 445nm Laser and a 455nm Laser?

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

Good Job, I like your info!

With the beam expander it looks like a real light saber.

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?

Purchase link is blocked, can you repost the link?

I recommend the 800mW 532nm PLE PRO from jetlasers that will go over 1 watt

i just got mine. its brightness is equal parts terrifying and badass.

Thank you for great review

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?

Strypo operates laser 10X the intensity in his room lol

I bought myself a laser 303 it is really good you got to use it wisely

are you engineering student, are you able to found the upper limit of heron's fountain ever possible at STP

few days back i encountered videos showing striking lasers on airplanes are bad, now I'm getting this on my feed interesting

Can these laser be used to protect themselves from certain situation under attacks or emergency situation?

If I can't fill a swimming pool with pop corn kernels and pop them all from space I'm not interested.

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?

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 Fred

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!

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

Besides a stainless steel casting what would you suggest for a casing with that type of magnitude of power

If you used two of those beam focusing attachments would it focus even better?

Dude your mind is in the right place

Just keep in mind watching this laser displayed on a wall will blind you.Wear laser glasses

All i want to know is, can it melt away wire insulation?

Nice video, I was into lasers a few years ago and there were no reviews on KZfaq (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.

Looks cool! I’m the guy that bought the nano s

Nice review. It's too bad that the laser goes wide too fast.

What's the difference between single and multi operation modes? It gives these as options when you configure your laser on their website.

Is the beam dangerous when there is no dot being reflected or appearing on a surface? For example, 100mW 532nm laser being used to point out a star, do I need glasses for just the beam?

Can you burn a gas station from a security distance with one of these? 😁😁💥🔥

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.

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.

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.

Looks like a Light Saber. :)

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.

Do you know how I could cool this laser to operate it for longer periods of time?

how far do i have to stand away to b e completely safe from the beam damageing my eye?

I’m afraid just watching this video without safety glasses holy crap.

So this can be used to laser point the ISS in space and see it on live feed?

Could this laser be used for surface mount electronic work?

You wouldn’t have a coupon code for Sanwu lasers do you. I’d like to order the striker. Any recommendations?

That laser is incredibly cool, but seriously, what can you actually do with it apart from playing?

Wooohooooo! Not Your Father's Mountain Ale. That's some pretty good stuff....

Great review. At what point...how far away, will it not burn anything

Does the laser come with the glasses and batteries??

Visible blue beam in daylight, that's insane.. Nice review!

CAN YOU IMAGINE WHAT KIND OF LASERS THE MILITARY USES OR DARPA ??

Don't want to ask stupid questions but what exactly determines the power of a laser beam is it the composition of the diode or a higher voltage?

What do you use it for, if you say you can't evan point it to the ski. Do you play with him, or do you watch him?

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.

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..

ok just a quick correction, beam expansion doesnt depend on power levels. it depends on frequency, beam waste (actual laser rod) or focusing lens. doesnt depend on power.

Was the lable correct?

What is the use of all these very expensive lasers???

PLEASE believe me when I say I’m not being sarcastic or trolling. This is exceedingly cool (no pun intended), but I’m not sure what this is for. Is there a practical use? For just fun, demonstrations, and experimental purposes, I guess I get it, but it seems there’s so much potential downside to using it. A powerful device, to be sure!

I try clicking on the site wanted to purchase the swun lazer doesn't work won't open?

That’s a beast of a laser! Have you got plans to review a Sanwu 1watt 520nm laser? There are not many reviews of that wavelength and power.

Well wildfires may not be caused by "your" laser...they are caused by lockheed martin's...

fascinating that this made it through customs. Extremely dangerous to the eye

hello so i need to get the x3 beam expander, 26650 battery’s and dual li ion batteries charger ?

Would this be a really good laser used as self defense while open water sailing? Do you think this would ward off people during the day and night?

7 watt? 7000 milliwatts?? Crazy

Wow i don't like that you have absolutly no beam at long distances. and for $50 more it should fix the beam completely. I'm glad you did this preview cause I don't want it now. Thanks for saving me the money.

Hi, Can u please tell me how to switch out the lense on this laser please?

Great vids do you know what lens comes stock with the laser?

Someone saw a mechanical Vape mod and said "hmmm..."

You've gotta love the Chinese!

What's the infra red output? And them lithium batteries arrive like that?

The last laser I dealt with was 7/100 of one watt and it plugged into a wall outlet. It was the size of a weirdly shaped loaf of bread (3 inches by 3.5 inches by 15 inches, roughly) and weighed a couple of pounds. I was told it used 2 one-way mirrors facing each other.

whats it like at taking down speed cameras.

Only downside to this lazer, if you so much as turn it on, ,'they' will know where you are. Kool unit tho. Can think of a number of useful purposes for it.

what batteries are you using

Also will the glasses with them even protect me at all
