Merged 445nm Pictures and Video Thread

I'm not sure either. It states that is runs at 14000 RPM and the air flow is 0.81 CFM (0.023m³/min) which quite honestly I'm not sure how much that is but the space in the mag lite is very small and it just needs to move air over the fins.

But on the other hand, I could fit a 15mm X 15mm fan in there to, which would move more air and is lot cheaper...
 





Test completed with two 18650s and the power at 30 seconds is now 1490mw
no real gain so the battery is working fairly well

OK edit: The alligator clip jumpers weren't enough to carry the load so now they are doubled up
it now starts at 1.7 watts and after 30 seconds is at 1.5 watts with a fresh cell
so there are no real battery issues

these things need a lot of heat sink!

This thread is almost pushed to the bottom and the last post wasn't even a day ago!

Anyways, new video:



I'm gonna pump out videos of this thing until blue is boring. :D

Wonder if you could shoehorn in a heatpipe based cooler from a laptop, northbridge, or hard drive cooler. Maybe use something like this to relocate the heat outside of the body passively.

Wow! That is remarkable. Who would have though that the most powerful diode available would be blue.

When i went past 2,3A it stopped lasing, but when i got back to 2A it was lasing again :)
 
That's interesting it does not just die. Maybe it has to do with heat?
Of course you can expect you used like 8000 out of the 10000 hour of the life of the diode in 40 seconds, lol :) +1
 
Maybe it has a special amp usage protection circuit like protected 18650 batteries :P So, Why not run the laser at 2300mA, and tell us how long it lasts under normal laser use, a few days, weeks, maybe a year... :)
 
No, huruu tested his up that high, and the it degraded the diode. Wouldn't lase as strong at normal currents anymore.
 
Well, that could possibly happen, but since i got no LPM i have no chance to measure.
