I see many people have started modding lights with a P7, how soon before we see lights with tri or quad P7's?:devil:
How soon before we start seeing multiple P7 lights?

I have a tri-P7 build in the works....

Oh nice! Can't wait to see your work 
. Saw your other threads and you did a great job.
I should learn to solder so I can try some small stuff and then try a P7 build.

Does mine count? I took two single P7 shorties and duct taped em together 
I would add....how soon with multiple P7, that have a nice hotspot and throw. Otherwise it will be a flood monster. It seems the major development in LED's needs to be mounting them on a superconducting heatsinking cylinder or sphere that can move in/out of a focusing reflector. Right now they remain stuck in "the Earth is flat" mode.

a 3-inch head would be promising. We need to get modders like Fivemega to make bigger (3.5 inch perhaps) head to accomadate 3 largish reflectors, not quite as big as the regular mag reflector.
3 of C-bin P7s in a light that with NiMh Ds would pretty much render most 500+ dollar HID under 30 watts obsolete.
figure 150 for the head 20-30 for the heatsink, 90 or so for the LEDs, 20 for a donor 3-D mag, 15-18 dollars for batteries, say 25 for the driver, an amatuer could build a 2700+ lumen light for around 150+30+90+20+18+15=320ish, except it can take some abuse, and can be turned on and off at will. It will get hot but eh, heatsinking will take care of most of that
its gonna be a fun summer.

I agree, and it exists,I have thought about it for some time and suprised nobody has implemented it! "heatpipes" are the key!
building a multi p7 is not the problem, but you will not get a small throw for a wide beam. or you need, maybe three big reflectors. it is like the ostars with the orinigal franel reflectos. brigth light, but much side spill. good for near aplications. if you want a flashligth for far alications you better take a hid with one big reflectors.
heatsinking is also a problem. my bigmag³ will get so hot after 10 minutes that you must dimm or shut off the light. it is like a formula one race car. very bright but not for contius use.
three p7 are 30 watt of pure heat that must also changes to the air. and therfore you need a big surface or active cooling. buliding a small multible p7 that runs more then 30 minutes or an houre is imho not realy possible. or it is very big and have a heavy wight.
example two: take one six die ostar and put them in a maglite with a massive heatsink. after 10 minutes running at 100% it will get also very hot!
heatpipes: ok take some heatpipes and then? where do you want to got with them? active cooling in a led flashlight ,not realy.

Multiple P7 lights!? Honestly, I'd be happy with a light with just one nice CSV0H emitter. Seeing as just one of them ~ equal to a nice Tri-Cree R2 torch, I don't see a need for more lumens. But, the first manufacturer of that torch would get lots of business from us CPFer's.
Also, what would a light that bright be used for? And I can't imagine how many modes it would need in order to be practical.

I'm thinking optics would do better since you don't need a gigantic one to capture all of that spill.
Since none exists currently, Perhaps 3 P7's in a 3" head (https://www.candlepowerforums.com/threads/192304) with McR27's(dunno if it'll fit, didn't do the math) and drive them all individually with DB1500's on a bunch of D LiIons. OR, If you're crazy enough to want more output, perhaps 3 sharks (wire all three pots to one external pot! STROBE anyone?).
I'm guessing heat would be the first problem.

The question was asked over at illuminationforums. The reply:
For multiple P7s, I think one of those bodies with a 10A tail switch (instead of the stock Mag switch) is indicated.Elektrolumens said:
