Hello guys, I wanted to ask, how safe is it to look without safety goggles at the dot reflected outside on a wall from a 1.4W blue laser (445nm) at around 15m (49ft) distance? Thanks.

Hello guys, I wanted to know at what power (mW) in green lasers does looking at the dot on a wall can cause permanent damage? I know that we can't look directly at the dot at powers around 1W, but my doubt is when that starts to be a hazard, of staring at the dot reflected off a matte wall at...

Hello everyone, I'm expecting for a Rayfoss 532-50mW-QMT laser to arrive soon. Does any of you know if the right battery polarity for this one is the positive to the tailcap? I just don't want to mess it up right away. lol Thanks for the help. The model is this one: 532-50mW-QMT

Hello everyone, I have noticed that most if not all lasers require you to place the batteries with the negative pole facing the diode and the positive towards the cap. Is this true to all commercial builds? If we place the negative towards the inside we can't go wrong and fry it? Thanks

Hello everyone. Will these batteries and charger from UltraFire (DX.com) work ok with a custom 7mW 532nm laser? Batteries: UltraFire BRC 18650 3.7V "4000mAh" Li-ion Batteries - Black + Golden (Pair) Charger: OEM 2*18650 Lithium Battery Charger (110V~240V AC) I was looking for a cheap price on...

Hello everyone. Sorry about the lame question, but what are the main differences between a 445nm and a 473nm? Also, which ones are used in projectors? Thank you.

Hello everyone. Does this host fit a normal green laser or like the C6 it can't be properly built? Build link: http://laserpointerforums.com/f52/ultrafire-u-501b-host-66616.html Also, does someone know why this 501B is so different than the Ultrafire 501B we're used to see? I find it really...

Does anyone around here build custom lasers on this host: I find that really cool and would be very interested in buying a laser on this host. Thanks in advance!

Hello everyone. I was discussing this in the middle of another thread of mine but since the theme wasn't exactly on-subject of the thread it makes more sense to open a new thread dedicated to this discussion. I have read conflicting reports, ideas and theories, here and elsewhere, about the...

Hello everyone, I'm here to ask you for some help. I am looking for a laser that has the maximum possible beam brightness while remaining safe to be used indoors without glasses. So I guess that I'm looking for is something around a 5mW green laser, correct? However my problem is that most if...

Greetings, I have been reading the forum for a while but now I am opening this thread to ask for your opinion and feedback. The Wicked Lasers Nano Series product features a 15mW green laser and a 100mW red laser version. My doubt is, how exactly do these two lasers differ? Do they have similar...
