After doing some researching and finding that CREE leds are EXTREMELY bright, I want to build a multiple CREE led flashlight. One of my current flashlights uses a CREE led and after searching the circuit board for quite some time, I have found 1 SMD resistor, and I can see 3 characters on the top of it, but can only make out the first 2 which is 24. so, if I were to build this multiple CREE led flashlight, what kind of circuitry would I be needing to create? I plan on getting some round circuit board from rad shack to base this off of.
I just ordered 4 of these suckers. What kind of battery power will you guys think I may need?
