Check that they are the 6000mCd ones. You can also get 1600mCd and 4000mCd which are not as good. > I was thinking a supercap would be easier to use, I also read the pulsing the light would be more efficient, in that case just a resistor isn't going to do it.. Efficiency is not a problem, these leds are MUCH more efficient than thefilament bulbs you have now. I've used a 3.3F supercap to drive a led, soon went back to a few small NiCds. Much better capacity and flatter discharge curve than the supercap. :o) -Roman -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
