100w led chip. i was hoping to pull the guts out my light so only the silver cone and lens was left and put this at the end of the cone.
What would i need to power this from the 12v marine battery?

thanks

You will need to mount the LED to a big heat sink.

did you read the feedback for the led? its actually 30W run at 30V

That's why he needs the boost regulator.

Huh?

The one the OP has a link to clearly states it needs 28 - 32 VDC at 3000 - 3500 ma. My math says thats about 100 watts.

i read the reviews i didn't do any maths or workings out i didn't use a fag packet or pen or paper! that's for you clever people to do! now if ive got it wrong that's good, it means all is normal!

Even 30W is going to need a massive heat sink. And you can always water-cool it .

Here are some heat sinks and even some complete 100 w. units.
