    Depends

    Depends on your location. If you live in the US try digikey.com or mouser.com. The best source in my opinion is ebay......

    i HIGHLY recommend buying name brands like philips/lumiled, cree, or osram. their quality standards are very high, translating to a very low failure rate even in harsh conditions.

    i believe member turbocad built a watercooled led backlight-- that might be a good starting point for something like this.

    otherwise, high power led's are not something that are easy to get into. in terms of parts count, they are easier-- all that is needed for a ton of light is a couple led's, a constant current driver, and a heatsink.. but in terms of complexity, you must learn about c/w ratings, and do some heat-dissipation forumula's to ensure that whatever heatsink your using will correctly get rid of any heat that the led produces.

    low power--ie: less then 75mA leds-- have a much higher parts count, but are much easier to design for--all you need is a ton of led's, voltage regulation, and possibly some resistors...

    also, i don't believe that the formula that was listed is correct-- adding a second led does not exactly double the amount of light output. it would increase it, but not that fast..

    while i don't have the math, i believe it is about a 125-150% increase in output over a single led..

    and that comes from my quad-reverse light retrofit that uses 4 1,000 lumen led's.(yes lumens, mcd is old tech..)

    I can't remember if Turbo made a water cooled screen as well but I know I did back around when this thread was current based off of his LED setup. Needless to say, it made it about a week in the car and I got rid of it. I still have 16 Luxeon Batewing 1w LED's with controllers in my attic awaiting the right project . Basically I found that for what little extra brightness I got out of it, my complexity went through the roof and the reliability was questionable at best. Simply the cooling alone was a big issue. Personally I would recommend purchasing a transflective before messing around with upgrading backlight. Back when we were doing this the transflectives were over 1k if I remember correctly. Turbo also was working with a really big screen. If you are still interested, I used LEDSupply.com to find my LEDs.
