Again... what's the 4 die CREE XLamp MC-E LED? And does this compete with the P7?
That's all,

My question is that I have a wonderful TW4 that I power from a rechargeable cell using a VG1 body. I have swapped out the Lux for a better tinted 5 watt however I wonder how this new emitter will do in a single cell application such as my TW4?....can it be done based on what we know about this new emitter so far?
From the links I read I did not see any discussion of a high power single cell application nor did I see any compare this to the only multi die emitter that I am familiar with and that is the LuxV.......thanks for filling me in on this.
I've always wondered about the SSC P7 versus the MC-E as well...for one thing the emitter dies in the SSC P7 looked a little too similar to those in CREEs from way back since the P4s, 4 rectangles laid out in a square-missing-two-corner shape.
Why the similarity when the rest of the SSC line staring from the USWOLs looked significantly different than those of CREE?
That's because SSC doesn't manufacture their own dice. They buy Cree dice (blue leds essentially) and apply their own phosphor for the P4 and (I assume) P7 LEDs. So yes they do look similar because they are similar.

This is a problem if you DD or otherwise overdrive the battery. If you use a driver that pulls under 1000 mA from the battery, it is no problem running from a CR/RCR123A.Running a high power LED like a Luxeon V or this Cree MC-E off of a single cell is a rather foolhardy thing to do, the amount of power being drawn from the battery to power the light is dangerous to do for any reasonable period of time and you run the risk of having your cell explode - I speak from experience as I've come close to explosions and had batteries vent on me having done just that while experimenting in the past.
Now, as to whether or not it can be done - sure. Wire the MC-E in a 2-series-2-parallel configuration and you've got a modern day Luxeon V equivalent, but mechanically you'll have to figure out how to make it all fit in a host designed for a different LED. It is possible, though.
