Awesome! I'm glad your new LPM is working properly.

Few things... move the laser further away from the sensor, charge your batteries, let it cool for at least an hour, before testing at room temperature, and make sure you are hitting dead center.

Hard to tell from the video but it doesn't look like the laser is centered... so you could see a somewhat higher reading even.

Awesome though, at least a 2.9W Laser :D Congrats!

Congrats with your newest LPM. It is sure faster than the Basic LPM :)

Thanks buddies :wave: I am really happy with it and i can't wait to send you guys a picture of the end result of the lpm in it's alluminium case with fast respons volt meter :D

@ infinitus You absolutely 100% right about on how to meter it i was to busy getting a good shot and i forgot to get the correct distance. Also i am not going to worry about the batteries and temperature that much, i am sure it can hit 3W.

I am still gonna sell it as a 2.9W laser. the difference between 2.9W and 3W is not noticable it is only bragging rights :tinfoil:

And if you really want a 3W+ laser swap the mode driver with the blitzbuck V3 set at 2.35A and bang :gun: lol

greetings,,

IE is it really necessary to let the laser cool for an hour for highest Watt readings??

This is a humble question, since it has a massive heatsink. If true then i've been overworking my little 445's , the ones at or above 2 watts.

Probably not, and I rarely do so myself, but in testing diodes, some members, far more knowledgeable and experienced than I am, have left their builds to rest for several hours before re-testing.

Told you it would sell instantly after a video. Well it wasn't instant, but two days is still pretty good :D
