Thanks wannaburnstuff for your informative posts, i'm looking at getting a high powered blue when i have funds!! I guess as in best of both worlds a cyan blue would be better than a darker blue!?

Hi, i think i've asked before but can't find my post! So whats the difference in colours? Blue, red, green, violet, orange etc! All i know is that green is the most visible to the naked eye & blues are the best burners! How come there is a 1.7w in blue for wample but not in green or red...

Yes, the inner silver screw thread barrel within the head!, done that! I didn't get it wet in the snow!

its not at infinity when screwed all the way in. Infinity is about 2 total turns away from totally screwed in. Trouble is, is that i can't get infinity at all. Will adjusting the inner brass screw that has the 2 small holes for plyers do the job!?

Hi, no, i mean i had never touched inside the laser at all, only after i saw the issue! Yesterday, all was ok, i charged it & was ok. I left overnight after charging, then went out & the focuser didn't work.

anyone???, i'm in a hurry here!!

Am not able to post pics as no camera here, but i did the same things as on this vid How to focus an O-Like power rock laser to infinity - YouTube as this is my laser! the inner thread was screwed all the way out & i had to screw all the way in to get the smallest dot!

Hi I have 200mw power rock from o-like. I charged laser to full yesterday & tried it, all was ok. Today i took laser out in snow & the laser was just a torch beam, it wouldn't focus at all, no matter how far i turned the head! Wouldn't narrow the beam at all. I took head off & using...

Hi & thanks I emailed my local University & what i assumed was the relevant department & was forwarded to a guy who i think was a Dr in electrical engineering. He questioned me a bit & invited me to his office where he tested my laser. He also wondered why i had such a thing as he had a 10mw...

I guess i'm prob just wondering if anyone knows of any 'known' shops that carry power meters for various reasons! Not necessarily to test the lasers that we use, but could be used for that!

Cheers for the offer, but prefer not to send stuff away! :beer:

Hi I'm wanting to test the laser i bought from O-Like as to whether it is 200mw as it came with no test sheet or info guaranteeing that it is 200mw. I am in the UK & in a city & was wondering what shops may have a LPM that could test my laser or if anyone out there could help! Cheers wf

Hi all Thanks I emailed Susie at O-like & she says that their lasers have reverse polarity protection for minimal time. I have fully charged the laser batter & it seems a lot brighter & burns better & up to now ok. How much 'on time' should the laser work for with a full charge? Would it...

oh bugger & that was the replacement for the one that failed & o-like were good enough to send me. once i got my battery fully charged from Larry, it didn't seem to happen for a while which made me think it was the old UltraFire battery! I've been using the laser a lot lately without...

Ok, here we go, i hope i can get to the bottom this. Trouble shooting replys wanted please! Got Power Rock 200mw from o-like as replacement for other laser that shattered! Laser dims after a 20 seconds of use even at full power with battery i bought from Larry DFW on here! Old Ultrafire...

Hi I mean that if when the end is screwed all the way in & thats infinity, when screwed out, will display a hugely wide dot/beam! I'll have a play later when dark.

Hi Thanks, i did this, but when i took the lense out to replace the end glass, it shifted a little! Locktight needed! I am waiting for night to get a good fine beam. Would it mean that when focused out, the beam would be hugely wide?

Thanks, i seen this video before. How can adjusting the lense without the end glass piece in do anything as he then removes it again, which i would have thought messes it all up again or does the end adjustment turn separately when attacking from the front as opposed to the back. Also, does...

Hi This is my Green 200mw Laser. Power Rock Green laser Torch 200mW /Focusable&Waterproof [OLPRGL200] - $132.99 : Zen Cart!, The Art of E-commerce However, i cannot focus to a very small infinity dot! Before, i could. When screwed totally in, it would be wide, then i'd screw out the...

Was still wondering though as to whether a new better quality battery can improve the output quality of a laser visually.
