fun with high power leds.

Been thinking about replacing the Acura headlights with leds but I don't want a large array. After many attempts with SEDs I think I have a winner. I think three each side should do it. If anyone is interested in the drive circuit I'll post a schematic when I get the exact values dialed in.Answers to the obvious questions:Seoul Semiconductor P7 ledKhatod 28mm reflecto

i would like to know more when you get it up and running. where did you get the leds?

where did you get this setup? I 'm sure i can find many uses for it!!!!

I made it. Its what I do. I'm working on REV.B right now. This one is going to slay.

WOW, that is awesome! They sure do look powerful enough...can't wait for your diagram.

im dyin to get my hands on these, they would look sick as some fog lights, whenever you're done let me know!!!

It will take some time. These are expensive LEDs and I dont want to publish anything until I'm sure the results are repeatable.

How big the heatsink needed to be with a couple of this? I'm working on a couple Prolight 3W and they are hot even with a big heatsink, I guess yours probably even hotter.

By the numbers its 10 square inches of heatsink surface area per watt. I machined a small heat sink for 4 leds that will have machine oil circulated through it to a small remote radiator.

How much light will something like this throw?  What kind of $$$ are we talking to build these?Jeff
