o-like 100mw ultrafire green laser

im looking at buying the ultrafire 100mw laser from o-like and i have a few questions about it. First what is its beam divergence like? Also what are its burning capabilities. finally will i need to buy protective goggles to use it or is it unneccesary? yeah im just looking for some answers. thanks to anyone that can help

Man, when Jerry sees the double posts you're gonna get it ....

The O-like greens have decent power specs, but the divergence is generally not up to par with the Optotronics, Laserglow, etc offerings. 100mW will definitely get you balloons, tape, etc for burning - to reliably light matches, etc though you may want to step up to O-likes pocket 150 IMHO

ha yeah kinda screwed up there....
and okay i was looking at the pocket laser but i read a review about it that said it had a very short battery life and it ended up breaking. that kind of turned me off but im starting to wonder if it was just a faulty laser

yeah and you said the o-like 100mw was is not up to par with optotronics. Whats that mean? like how far can it shine before it becomes a large dot?

FOR THE LOVE OF GOD DO NOT GET THE LASER WITHOUT GETTING GLASSES.

Get glasses for any laser over 5mW.

Even with the glasses there is still going to be a minimal safety issue with IR but should not be too bad for looking at the dot just don't take a direct hit through the glasses.

it depends on the actual laser you recieve, the beam specs can be all over the place with cheapies (although most are still a decent beam, just not "impeccable" like the LG and Opto offerings - then again, they are a fraction of the price) ....

Any single CR2 or CR123 laser is generally going to have a short battery life if it's putting out 150mW, the average CR2 is 400-500maH, and considering you are likely pushing a minimum of 1/2W pump to create 150mW of output, the battery would be to zero in about 40 minutes - realistic runtime at full power will be much shorter (I have a green module that puts out 173mW peak and I have to recharge it every night after I use it at the shows, and it probably really only is on 15-20 min total all night)

Keep in mind that alot of these low-buck lasers can't take the 3.6v versions of the CR2/123 and people insist (far too often) on running them in their lasers, that explains at least a percentage of the failures we're seeing, IMHO.

Hope this helped - I still wouldn't steer you away from that 150 if $ is an issue, just if you have some (OK, a LOT) more $$ the LG and Opto lasers are definitely more of an investment than a "purchase" (I hope that made sense)

brew your in the i/r post range now be carefull
