has anyone ripped one open and tested the power output on the diode?

Especially the red ones. It's really hard not to get a 301 that's not 200mw. But their LED drivers blow up sometimes
Im having a blast AgentMcBaine with the red 301 you sent me, a focusable 190mw red is alot funner that I ever thought it would be. I should of known and realized that from the fun I have with my 112mw Pman special. Im running that red 301 at no more than a 60 duty cycle, how much longer can I run it before I burn the driver out? Also are the modules heatsinked in any way on any of the wavelengths they come in regardless of how small that heatsink may be?

I have ran my green 303 for about 5ish minutes with little to no heat generation

has anyone measured these on a laser power meter?

Yes, but the powers are all over the place, usually way over spec. That reminds me though, I still need to meter mine...

well that is good to know. although the supposed 10000mw 303 is probably under spec by just a lil bit:whistle:

I guess I just have to run one of my 301 to the ground and take it apart to see exactly what it can and cant do. Ill probably chicken out last minute though

I haven't seen those! :p But the "5mW" units (Gearbest etc) have pretty much all metered over 5mW. I'd say mine is doing at least 30mW of green + whatever in IR. They are hit and miss but for $8 you can't really go wrong.

Personally my 303 Laser is my most used laser by far.

I've had it for well over 4 years and no matter how many times I drop it it never quits.
And the fact that I can run it continuously without it malfunctioning (so far) is a very important factor in photography.

My first go at photography I had it running continuously for well over an hour :p

And the results are in for my 301!



For whatever reason the software only logged up to 45 seconds - but I did meter it for 60. Peaked 83mW, was down to 75mW by the 60 second mark and averaged 73mW, including the time the LPM took "catching up". Pretty decent for a "5mW" laser. Although, who knows how much IR was in there. I'll need to put it in front of my 808nm goggles and retest.

Now I feel silly keeping mine to 60 secs
