That sounds like a great idea too.I also anticipate this package hosting a red-amber-gren-blue emitter setup in the near future, where independent control wuld allow variable color.

Its funny, as I was about to push the "submit reply" button on that post it occurred to me that it was probably incorrect. Then my next thought was "It's ok. Evan will be along shortly to clean up." Thanks. This is one area I've been needing to really buckle down and try to wrap my brain around the formulas involved. I HATE math. So I've been avoiding it.
Maybe you can help clear up something else as well. I was trying to look up the specs for the P7's thermal performance as compared to the new Cree MC-E and found two different results. This one says 7.5 C/W and this(must click on the "W724C0" spec pdf at bottom) one 3 C/W. Why such a different spec for what appears to be the same part?
Even the worst bin (370 lumens minimum @ 350 mA per die) comes out to over 80 lm/W. Can't wait to see where these are this time next year. I think 550+ lumens at 350 mA per die will be a very real possibility.An just think, what we see now is the bottom end of the line. The brightness and efficiency can only go up as they perfect the process and make improvements!!
Hit the AAA with a 5.8 amp draw. Make it suffer! Mwa ha ha ha.So THIS is what Mag has been delaying the release of its LED-based Solitaire for.

I think I just wet myself
:laughing:
Not sure yet what to think about the MC-E. It looks exciting in many ways, and I'm sure it will have it's strong points. But, unless I'm missing something, if you want to run it in series, this thing will NOT be fun to wire up.
I think that I am going to have to move up my estimation for an off the shelf kilo-lumen flashlight.

If you graph expectations vs time for non- scientists and compare it with the same graph for scientists, the science graph is always steeper. They expect things to happen faster.
What curve is even steeper?
The actual time something happens.
How long has it taken Cree in the past to get from this sort of demonstration to it's LEDS being available? The gap between SSC announcing the P7, and individuals and resellers having the LEDs was fairly short.
