What I meant was that the heat to output ratio is not really a good ratio in leds. That led your looking at is known as the cree and yes 400 lumen is alot and putting 6 does theoretically output 2400 lumens but a standard 4200k 35w hid set puts out 3200lm. But you are right about leds, unless they can be focused in a certain direction, they are not going to be usuable.

Idk about led headlights, if i did have the 04-05 headlight and harness though id think about getting those as the brights.
On the other hand, as much as i don't like ebay i know a guy that got a set of hid's from this guy on ebay and im actually very pleased with the results. Hes had them on for over 4 months now and they still look very good.
I have a pair of Siemens/Phillips Hid's and his look pretty damn close to what mine are.... only 70$ idk i might get a set for my fogs and see how they go. I guess the pics this guy has on ebay are real pics of his hid's installed too.

a heatsink?
wtf..
I've been using them for ages in modded PC boxes and Unless it takes longer than the 20 minutes I work with them on to get hot, I'd hardly say they get anything more than "warm" as you call it.
I'm sure they get warm, but cold cathodes get warm and these are not as hot as cold cathodes...
Honestly, if these are hot, how hot is a headlight bulb, cause I've gotten blisters from headlight bulbs that I thought had cooled off after 5 minutes.
with HID its usually the bulb life that is a problem.
Many dont even make the 150 hour mark
3200 is an ideal lumens rating for HID, many dont make it that high, especially aftermarket kits.
also, for those who want really blue light, you can get more color at a higher brightness than many 6k or 8k hid kits.
I would be more interested in 2 of these leds used as turn signals.
Now, an interesting thing to do for anyone who had some projector fogs available for an experiment would be to take one of these sticks with 3 leds on each end and mount it sideways in the cup, so that 3 are angled up and 3 are angled down and then place a small mirror diagonally against the cut off shield to reflect the other 3 leds back to the upper half of the cup so the light could escape over the cut off shield.
It would be very inefficient, but much cheaper than HID for anyone with some spare circuit board and a soldering iron.

i dont understand the argument here. LEDs by design do not get "hot" of course they get warm as there is electrical energy supplied to them. that is the beauty of the LED no real heat.
oh and BTW thanks wiki. who writes this stuff???
Research on DNA
The DNA in salmon sperm has recently been discovered to amplify the effects and quality of a LED light.
Oh yeah, a buddy has a high-end luxeon flashlight and the body of that thing (the heatsink) will get warm enough that you surely don't want it in your pocket..... and it's NOT overdriven!
well thats no good!
in an overclocked 4.8 ghz computer, heat is the enemy.
Maybe I ought to take them out, I mean, they've never actually gotten hot probably because they are mounted to the shell of an aluminum lian-li case, but im sure their not making the fans job any easier.
i work for an LED electronics company and LEDs mos def produce heat! that's one of our biggest concerns is heat transfer...
I guess this may be true since everyones saying it
i've just never really noticed heat from leds.
I've always heard that they produced very very little heat for the light output, but I suppose when you start getting at higher light outputs you'll be putting out more heat too.
^^ yep LED's are pain the ass to work with because of this particular heat problem. Turn signals would be great for these though.
wow, these are really expensive. It's probably not even worth it...
i got led lic pl lights!
What about OEM fog light bulbs?
