How do i build this, how many resistors do i need. i have 10 i just bought, they are 10ohm 1/4 watt 5% tolerance, and the 5mm 12000mcd led's are on the way

Here's a link to how to build one of those. I would use (3) 18 Ohm resistors..myself. http://flashlightreviews.home.att.net/mods/prbulbs.html

Thanks man, i'm planning on doing that when i get me leds, first mod buy the way

/ubbthreads/images/graemlins/smile.gif The first ones always special...lol. Though, the more you get into it, the more complex they get. A lot of people are really into the LS mods, but I still enjoy working with 5mm leds the most. They are cheap, bright enough for my purposes...and don't pull that much juice. And of course I don't have to worry about ruining a few when I experiment with new designs.

If you want to calculate the value of the resistor you should use... use this equation... it will get you close enough...

(Source Voltage - L.E.D. forward voltage) / L.E.D. forward current = R (Value of the resistor you should use)
