https://www.ebay.com/itm/136850551538?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=-jY7Zkw8SbC&sssrc=4429486&ssuid=5asqIH94R6W&stype=1&var=&widget_ver=artemis&media=COPY 7W rated by osram! This monster must make around 12W pushed to its limit and cooled.

Looks to me like a simple buck driver, usng the LM358 opamp to drive a transistor to deliver a constant current to the diode (Battery voltage should in theory be higher than the diode voltage) unless i'm mistaken, hard to know without battery specs, diode specs, and driver schematic/parts names

Awesome! Wow, what an insane deal!!! I've added it to the list!

Thanks so much for using this list and contributing to it! This is exactly why I've created it! So happy to see it being used. I've added your findings to the sheet and given you credit in the info/source tabs. For the NEC NP-605UL, if we go by this video @33:11: which contains 4pcs NUBM05...

awesome! thank you

This bin is no longer available. :( Nice solidworks work!

The drama on this forum is unreal and unrelenting lol

My shop shows all colors except 573nm which hasnt been added yet I sell a 4W LPM as well: https://jlasers.org/products/ls4-laser-power-meter-4w-max

Yes sir :)

I also make DPSS 555nm, 573nm and 591nm, shoot me an email @ sales@jlasers.org

Survival lasers isnt selling anymore heres what i recommend: https://www.laserlands.net/protection.html

The cheap acrylic lenses I've been using can be prone to that. I recommend buying a 2E lens which are metal and much better quality. I plan to upgrade all my lasers with 2E lenses in the future, but that will come at a slight cost increase

WOW :love:

Thank you for buying my products! Remember that we offer lifetime warranty should you ever need it :)

These are slowly being moved to my website https://jlasers.org/pages/tests

555nm, I have a spectrometer

I texted him on dis.c.ord, I'll try to make this right for you. This absolutely sucks. Honestly, im still hopeful he isnt running with your money. He's always been straight with me, although very slow to pay. He truly is busy and overwhelmed, kinda like me. We'll see I guess.

i think PMs are broken at the moment on LPF was it a RGB handheld u wanted or 3 different separate pointers?
