Yea, I know... Noobie, use the search function. I did that and have a bazillion hits. None of the first 100 however tell me what a CREE actually is, why it is special or why I would want one. Any insight would be appreciated. Thanks!

It's a new type of LED, think Luxeon but brighter.

A Cree XR-E LED released around last October is about twice as bright as current Luxeons LED's OR can be made to run twice as long on a battery at the same brightness as a Luxeon - i.e. twice as effecient.

Try an advanced search on Cree by user 'Newbie' - he has extensive info on it in several message threads.
Was going to say that Cree is actually a semiconductor maker in the U.S. that produces LED dice (the actual light-emitting semiconductor chip).
Their LED products are euphemistically referred to in shorthand as "Crees" although they have actual product line names (XLamp3, XR-E, etc.).

Trick question or not, I'm answering it. Don't ask me why, though. 
P3 and P4 are the flux bins of the XR-E. The P4 is brighter.
...Unless, of course, you're talking about the Seoul SemiConductor (SSC) P4, which is its own emitter with its own bin codes. It's based on the XR-E die, but has a few differences like radiation pattern and such.

Cree is one of the better Leds, more efficient than the Luxeon

I agree. I didn't know either and now I do. Thanks Tigerhawk.
We use a lot of abreviations here and since I've only got bitten by this bug two weeks ago, I don't know what most of them mean. On the upside, In the last two weeks, I've bought a M6-CB, a Kroma Milspec, 2 G2's (actually my favorites out of the lot), 6 Mag Led Upgrades, 3 Luxeon Diamond LED Mag upgrades and 144 123A batteries. (Yea, I got it bad...)
If you really want to know what a CREE Chip is and its Exact Specs take a look at their website ( http://www.cree.com/products/xlamp.asp ) Cree LEDS tend to be a much more efficient lamp. The XR-E LEDs put out around the same amount of light as a Luxeon III while only drawing 1w or the same as a K2 while only drawing 3w of current. The best way to learn more about something is to research through the company if they are willing to give you the information.

The simple answer , of course, is P1.
