That is only 1w mind....
I found it really easy to make one myself.
*dropin kit from DX
*1050ma driver from KD
*3w UV emitter from KD
Just need to desolder the led from star, thermal epoxy it in the dropin, attach driver and bypass modes.
The 3w led at kai doesn't have a fantastic wavelength but driving it quite hard (1A) produces a ton of UV, I've been really impressed with the amount of stuff it picks up.
