Heh thanks, when I first built it I was blown away with how bright it was. I was sitting there for a good few mins admiring how insanely bright it is. Now almost a year later 4k lm does not seem like much. Waiting on cree to release something crazier than an xhp70.
Pics of build and beamshots! It is BRIGHT, easily past 4000 lumens. Switched to mini lipos to keep up with the current draw. It now overheats in under a min at max.
A 9v battery can put about 500mA. Without accounting for voltage sag, that is 0.5x9 = 4.5w. The power supply has a peak efficiency of 90% leaving you with 4.05w to the LD. LD probs has an efficiency of 25% so that would be 1w of output not accounting for losses of lense and voltage sag.
Anyone here have a LPM and 445nm diode? I have some strange lenses that came out the PJ with the m140 diodes. They seem similar to the g series lense as they are both single element but mine do not have a mounting rim. I'd be happy to send a few to anyone who wants to provide some graphs or...
Knowing your guys love for WL I thought I share this.
For 350$ you can get a laser projector controller (no projector included).
Seems like WL last breath lol.
Re: FS/FT M Type M140 35$ Shipped US and misc parts (g9 lenses?)
Ah thats an A-type, M Types are more efficient and pump out 2+ watts while A types only get as good as 1.8. I had some a types up 4 months or so ago but ive run out of them. Atypes are 450nm I believe while m types are 445.
Im working on a short presentation for class and I chose resonance, specifically how resonance applies to lasers.
After wikiing laser resonance and reading up on the basics, I still have no idea what is going on.
What determines the wavelength?
Where does resonance apply in lasers?
It is a...
Lol not many people use the sst90 anymore
its the xhp70 and mtg2 leds (both by cree)
MTG2 has a prettier beam (uniform emitting area) while the XHP is far brighter. The sst isnt as efficient so I would not really recommend it.
Because of the shape of my reflector, the beam has a slight plus...
A few minutes is no problem, 40 shouldnt be a problem however the beam will get wider the farther you get away.
Your prob looking for this 2000 Lumen Zoomable CREE XML T6 LED 18650 Flashlight Focus Torch Zoom Lamp Light | eBay
It has variable focus (flood and throw). You will get roughly 800lm...
