In case you haven't sound proofed your window yet... Get a pull down blind and cover it with felt OR a vertical blind and cover each leaf with an insulation.

All right, apparently in the video the batteries that I used were actually not good batteries. I don’t know if there was an issue from batteries plus giving me bad batteries, but I will be doing a re-review on this laser.

I talked to the builder of the laser and they said that it was incredibly under powered and the batteries were bad. So expect a much more lively and explosive review on the next one.

You can actualy readjust focus of these 1.6w laser to the infinity. Beam divergence of these laser diode 2.5 mrad by 0.6 mrad when it's focussed correctly

Oh my gosh, halfway through and he is still rambling. My eyes are crossing.

I have a 7500mw that burns immediately. Started my campfire from 20 ft away!

11:54 min. i wonder why it needs so long to ignite the match with an 1.6 W Laser and focus on it. With my 1.1W 447nm Spartan from Dragon Lasers it burns instantly without focusing the beam at this distance.

Batteries commonly found in ecigs specifically the ones that looks like a kazoo maybe smaller then what u need but it is free

[bluethunder]

The black one end actually does turn to focus mate . Give it a try the very end bit

I saw Jlasers has a 3.5 watt 450nm blue for 90$ in the same size host.

Those are both class four LASERS not class three. They only know the only way to know the true output is to buy a laser power meter. The LASERS’s wavelength should be covered by the glasses, the optical density number tells you to what extent it covers that wavelength. Mainlely lasers on eBay sells a 7 W plus laser for $120.

I hang 1 foot wide strips of black linen 1 foot from the walls around the room off the ceiling and carpet 4 foot wide across the bottom half of the walls. No room sound after that

[jra]

there are tons of the 5 watt blue ones all over ebay for $38

[Adamisgood]

I can manually focus my 2 watt laser, that looks exactly like your 5 watt host.

5:26 max power is kind of like a joke number, a meme, a myth when it comes to laser pointers. if u rammed 5w through that laser pointer, it would instantly break.

[stefpix]

Good for dealing with double parked cars’ tires?

[johnnywick]

That black laser is tested to be 1.5w not 5w. Almost all laser pointers have fake power numbers.

If it was actually 5w, you would be crapping your pants when using it inside of your house.

That tiny one, too unlikely to be a 1.6w one for just 60.
1 way to guess laser pointer powers is to look at their batteries. If it's a 3.7 16340 one like the black one has, it's 1-2w+ usually or higher, max maybe 2500 but 3 is really pushing it and is VERY unlikely.
if it's 16xxx one, then 2000-4000w is more reasonable. 4000-7000w+ ones usually use 2xxxx batteries.

Also the black one is sold everywhere over eBay, AliExpress and over different dropshipping websites.

I will be getting a yellow laser by Monday!

[mortadhaabdul]

Does it ignite candles or newspaper?
Thanks

[johnwayne]

Do they have them in different colors?
