Triple PHR Light Build

I just finished final testing on a new light that combines 3 PHR diodes.

The light was designed for 405nm UV inspection duties,
with fairly long duty cycles (~15 min.).

I used a triple reflector to concentrate the light in a narrow beam.
It does not utilize aspheric lenses on the PHR's.

The difficult design parameters were driver design and adequate heatsinking ability.

It is mounted in a finned, black anodized host ~2" in diameter and weights 13 oz.

I built and tested 3 different electronic drivers, before finding one I felt was reliable AND protected against static discharge.

It is delivering slightly over 300mw of 405nm.

It is powered by two Panasonic #18650 lithium-ion batteries (2600mah).

Here is a photo of the "business end" of the light:

Now, I should have some time to get back to my Hi-Power Red diode testing.

Wow that 's crazy, I was thinking about doing the very same but instead of 3 phr's diodes I was thinking about using 6 of them but you beat me to it also it looks to me like you did some planning, and you did a great job BTW.
