    How should I choose a burning laser?

    Thank you Ragebot! I was reading this thread and thinking the same thing. Welding eyewear is NOT a substitute for real laser protective safety glasses such as the Eagle Pair.

    My NUBM44-81 450nm 8 Watt Laser with Home Made Beam Expander "Thor's Hammer" !

    Re: Testing My NUBM44-81 V2 450nm "Thor's Hammer" with a Hyperion Argentum 20 Watt LP The peak power reading is pretty meaningless with thermopile meters. What is the average power reading?

    1w green vs 7w blue?

    Get the 1 watt green. Unless you can get the 7W blue with corrective optics the divergence of that diode is terrible.

    Intermittent fan for intermittent LED, or steady? Thermal question for 100W system

    I build high power LED lighting systems for ....indoor gardeners, and my advice would be to run the fans 24/7. Keep the LEDs as cool as possible.

    Not sure what my grail light would be. My favorite light is still my Elektrolumens Tri-Star Phazer. I have brighter lights but that one still....just feels good in the hand.
