i bought these LEDs
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7605817579
i got screwed on the free resistors tho.
the first light i need to repair is my 18v Black and Decker
5 lights in series is 3.6v each so i only need to limit the current correct?
can someone help me with the formula for the correct paralell resistor?

i was thinking of buying some LEDs to mod some flashlights..
i serched "Nichia" at digi-key and Mouser with no result.
was hoping to buy a bag of 50 or so inexpensively
but theres so many to choose from i dont kno where to start..

are these any good?
theres some 130,000 mcd leds on ebay are those easy to work with? need heatsinks?
my plan is to series 5 for my 18v black and Decker? sound right? or maybe just 4?

heres some batteries i have been planning to make lights with..and my cordless driver should be able to support a LED
no? with a momentary switch? it has a nice 3.6v battery of some kind in it and a charger so it NEEDS a bright LED added to it...just begging for it.
the 12V brick came from a near free after rebate UPS... my orignal plan was to a make a battery powered computer
frmo a mATX board but...anyone know how to do that?
i have a 5" LCD display for PSX thats said to be mod'able for 640 VGA.. ...or i can just jam the thing into my Dorcy 6v lantern battery and run LEDs forever between charge.
