Need a driver for 1xCR123 to drive a 3.5-4.5Vf LED

mckeand13 · Apr 29, 2014

Looking for a driver to power a UV led from 1xCR123.

Spec sheet here:
http://www.ledengin.com/files/products/LZ1/LZ1-00UV00.pdf

Specs:
Min Vf = 3.5 @ 700ma
Max Vf = 4.5 @ 700ma
DC forward current max = 1000ma

I need the driver, if one exists, to be as small as possible. I'm trying to figure out if I can jam this into a Surefire M1.

I suppose I could use an RCR123 (16340) but I'd rather stick with CR123 if possible.

Thanks.

Try the Badboy Nexgen from The Sandwich Shoppe.

I built a UV light engine with the same LED, and used a BB Nexgen 500 from the Sandwich Shoppe. I will probably change the converter to a GD500, or maybe a GD667 to get the ability to use both primary and RCR cells. Regardless, it works great and the UV output is simply amazing. The light engine did a full cure on Norland 61 in less than 30 seconds. (It was probably done much sooner, but I was afraid to test it until after 30 seconds.)

Thanks guys.

I've got an email into the Sandwich shoppe. I've never used their boards before. Seems like there's at least one option that will work.
