Holy crap! 400 lumens at 350ma!
When it comes out I'm going to run it at 1000ma and just have one LED!

Oh well Eye-wink

Just like the other XR-E when they first came out, these are 700mA limit.

The whole point of this, of course, is that you only need 1 emitter (it's actually 4 separate ones in the same package) and therefore 1 lens. Cheaper, smaller. Don't forget, because it's 4 emitters you need more voltage drop too.

This will run hot mind... lucky I have some old CPU heat sinks lying around!

My mate has bought a few of these, http://www.luxeonstar.com/item.php?id=5537&link_... .

I am waiting on some sample ICs to build the current source, he can sought out the battery and heat sink.

That Luxeon looks good, until you read this:

Standard Fraen and L2 lenses are NOT compatible with this LED. Lenses are not currently available.

Doh!

Although if i go 4 x R2's, I think i'll need a bigger heatsink....
