3.6V~9V 800mA Regulated IC Circuit Board – 3.6V~16V 925mA Constant Current LED Driver Board for Cree and SSC LEDs (4-pack) Reviews

Involvement:General (knows how to use it) - Ownership:more than 1 month

Pros:
-Small diameter ( 17mm I think) - Fairly efficient ( 85% based on (power out)/(power in). The load was 2 SSC P4's in series with a 7.8v input voltage. - Actual current output was 820-850mA
Cons:
- If you want to use it outside of a flashlight you have to solder directly to the PCB. The outer ring is - and inner pad is + input. The Red+ and black- wires are the output
Other:
There is a negligable voltage drop across the reg. I'm not sure how it will handle as the battery discharge. Still happy with it.
Bottomline:
Hard to beat for the price
