Sanwu Striker 7W 455nm Blue Laser Pointer Burn Test 

when is your 4/20 special coming out

"Will it burn?" That is the question. Seriously, this needs to become a series.

The problem with using matches as a demo is even a 1/10 watt laser will ignite a match, just cheating what separates the 'men from the boys; is burning white paper preferably not tissue and white balloons, but ALWAYS USE EYE PROTECTION even with the reflected light even off the white paper. Overall good video.

Very informative video-the range of the laser is impressive. Thanks for sharing!

Ive just purchased a 1 watt red single beam with a g7 lens & beam expander, will be interesting to see how that combo works. i will attempt a video review of mine when it gets here to the UK in a week or 2. Great reviews by the way, keep up the good work.

yeah that is impressive! I like Sanwu lasers. There not FAKE! I bought a 1.6 watt laser from them - works great!

Excellent video, could you tell me the measurements of the beam at the output please. Thanks.

For a split second I thought the Soldering Wire was an explosive device.

I noticed that the beam at distance had a pronounced line, instead of a point or dot. That power would have been spread across the line, hence your difficulty with burning at a distance. Seems to me that indicates a lower-quality laser.

What happens if you feel the balloons with propane do they explode? And what about a hornets nest

Looks dangerous I want one

(I'm so anxious!)

So something I noticed today. I was playing with my 1.6w 445nm guardian and noticed there was a high pitched screeching coming from the focal point as it burned a roll of tape.

If i use it the way they recommend to use it how long would it last and what kinda of warranty do they have coming from China

Mine won't really work. Even with full charged batteries. It stutters and is no longer I bright Seeable beam anymore. It's weak and won't burn anymore, and idk how to fix it. I have that same lazer pointer

yay you got 50k subscribers congratulations

❤❤❤ brilliant project congratulations ❤❤❤

But what would it do to a squirrel at say... 15 feet?

Damn that Cheeto absorbs a ton of the light, I’m kinda surprised

I wonder how long it would take to puncture a steel belted radial tire @ 35.4 feet?

Keep in mind the batteries will deplete fast with a 7Watt laser. During your test you need to swap out batteries often for max laser optical output. I have a 2.5 watt laser and I swap out batteries often. Makes a big difference!!

Is the beam visible in clean air, or only through dust or smoke?

Can u find another unique laser to review

I have a seven white laser I would like to buy more powerful ones if I knew where to buy them

what will it do to a drone? is it dangerous to planes?

Anyone know how far away you can burn without beam expander? Is this expander x3 or x5?

I want to feel like a stormtrooper with this thing.

I know I’m late but I’m I still able to buy those in the us?

There's a member named Exerd on LPF. He's not always active on the forum but I know for a fact he is currently producing some of the highest power lasers, because I visited his machine shop which is actually local to me and got to see first hand what he has been making and selling privately. He has a laser which uses 3*32650 batteries in a rather large flashlight host, using 4 NUBM44 V2(?) diodes that are knife-edged, prism corrected, and beam expanded to something crazy like 8-10x he said. He was hitting trees over 4000 yards away and I could easily see the actual dot that far away, and it was intense. I managed to get a photo from the next town over about 5 miles away of him shining it into the sky, and from 5 miles the beam draws a blue line all the way to what looks like infinity (although I know it isn't going that high in reality). The output of that specific laser was over 26 watts and used a PWM controller with temp sensor at the copper diode plate. The last one I'm aware of that actually sold went for close to $3500, so they aren't cheap by any means, but he uses commercial grade components from Thor and Edmund. So far I have seen nothing get close to that guys lasers but they seem non-existent on RU-vid. I'm going to have to drive out to his house and try to convince him to make a video because his lasers are out of this world. This laser reminded me of a much smaller, cheaper version of the work he does but these are still really nice looking for Chinese quality. I guess I didn't realize my sort-of neighbor was doing things above anything I've seen online, laser wise. (But could have to do with legality issues at such power levels, too.) Thanks for the video very interesting stuff; I love lasers *almost* as much as gen3 night vision, but not quite that much. ;)

Modern day version of "A Christmas Story": you'll burn your eyes out!

Where did you get the flash paper? Link please

How come the beam looks red sometimes?

That's awesome. I want one. Is it painful to skin immediately?

I got a question why are my red and green lasers so good and my purple (405nm) is a blurry purple area and really bad

Where to buy this in 2022 ?

Have so many thoughts about what I want to do with this joint 😊

Will it burn cardboard at 20 feet?

Hey how much watts is the Arctic laser? Is it about the same as this one or weaker?

Metal wire or solder?

I wonder how far it would cause enough heat to start a fire make starting brush on fire a breeze lol and cut out that trusty ole gas trail but I wonder what the range would be

I have ons of these and believe me they burn. I put mine together and wen u turn it on its not instant it powers up. I clicked it on n off thinking maybe batteries wer not correct way. Obliviously i had pressed it again and unknowingly burnt a whole through my doona through my mattress

Nice video -What strength laser would one need to make a CNC laser cutter? (for wood up to a 1/8th inch thick?? Thanks

I think you need laser glasses just to watch this video. After watching it I found the I had a headache and my eyes felt funny for a while after watching it.

wait till you see styropyro 200W laser bazoka

bro plz tell me indian rupees how much indian rupees?

How do you avoid burning yourself if you cannot see the beam with protective safety goggles on? Also, how are you even finding the laser beam to place things like a match head directly in its path?

Hi, I just bought one just like yours and mine does not burn paper even though I focused the beam for about 30 seconds. I think mines must be defective. I am very dissapointed with it, it doesnt look as strong as yours at all.

Any coupons for the lazer?

How reliable are laser pointers in general, like do they break straight away or are they long lasting.

Can you light charcoal?

I have a renovated log cabin and carpenter bees are eating holes in it. The destruction they do is incredible. I would like to take them out at 10- 20 feet. Is there a laser you'd recommend? This looks like a little overkill. Thanks

When are you going to announce the winners for the giveaway

Yo anyone got that Zeus X - Super Powerful Blue Laser Pointer 7 WATT 450nm

So let's say somebody pulled a gun on you and life in danger you feel, are you allowed to zap them in the eyes with this laser?

What about the battery

Whats the best laser Quality/Price? I want to buy one laser pointer to burn. Whats the best?

3:03 where’s the link for the dry leaves bro?!

Is it worth the 480 it costs , shood i upgread i have a 5 w now i dont really have the money but i kinda do IS THIS UNIT WORTH IT

If you use this to illuminate the surveillance cameras on the street, the surveillance cameras on the street will be broken.

Where are you located and how do you get things like this shipped without customs seizing it???

I just found your channel. have you ever tried to shine at the ISS in space? and see your laser from ISS LIVE FEED?

What is the most powerful handheld laser you’ve ever had?

You missed testing for grill marks on a pan cooked steak

Please do the burn tests not in a white tile bathroom, it just washes it out completely. You can safely do them outside with precautions and a beam stop...otherwise perfect reviews..

How far does a visible beam travel ?

Intro song?

Could this light a roof on fire? Asking for a friend

Where did you get that dry leaf?

I bought a laser like this and it only puts out 6,300mw on my power meter

I only like DPSS and single mode diode lasers.

Would it burn my skin? Also how long did it take to ship?

On website it says burn laser for 60 seconds and keep turned off for 60 seconds too cool down but noticed in ur video I noticed you went beyond it limit, is it still okay

....IMHO: You REALLY ought to include a segment on selecting, and using "LASER SAFETY GLASSES"!!! = WHAT IS RECOMMENDED!!!! WHERE to Obtain them?!...

Need a Gigawatt, Flux Capacitor.

Can it ward off a dangerous dog ?

Guys can you reccomend any blue strong laser on Aliexpress, I like lasers I got couple green cheap 15 usd lasers but I wanna buy for 35-50 usd range blue laser, thanks

Us it good as a,camping fire starter???

...wishlist. 😁

6:47 - that tripod is simply too unstable. wobbles like crazy

If I shined this at the ISS, would they be able to see it?

I wonder if it would have the power needed to burn through a slice of McDonald's cheese ????

Try with a scorpion.

0.5 mW is the FDA safety limit. this is 7 watts?! Damn it will burn stuff quick! Never play with this.

A cat toy for people who prefer to cremate their pets before death rather than after.

I want to make a 1 kw laser

First time I've seen Cheetos being used in a laser burning test.

This laser is a killer. I wonder what happend if someone gets this in his eyes without safety. Rip him. And please never try it.

445nm

how much this price

Sup

that sure as hell isn’t 7 watts. more like 1.5

I’d so get in trouble with something like that. Precisely why idiots like me don’t buy these toys as I’m dumb enough or just to damn curios to see what all it can do. So yes I’d be that moron seeing if I could set the neighbors tree on fire

Dead link to buy this laser bud.

So it's a $500 magnifying glass

Use the sun

Could it cook a baby?

380 dollars :0

Well it's not 400$ cool

Ready to donate it yet? Lol

Seems less powerfull than 4W
