Multi-emittor D26???

I am planning on making a multi-emitter light for max flood. The light will hopefully be a D-26 light on 3xRCR123, with emittors mounted to a holder on top of a normal Cree-module.
-Is it possible to regrind or machine a new top on the D26 reflector into a flat socket for mounting three SSCP4 emittors in series, and substituting the original driver with one that supplies 750mA from 12V to three leds in series?
Will the heat generated kill the entire application???
 
BTT.

Why haven´t this been tested....just to machine a new part replacing the reflector on the Cree-modules from DX or similar. Do it like a big flatbottomed cylinder with room for three LEDs! replace the driver with a higher voltage model and wire the thing!! Saw a guy that did it with four Rebels under small reflectors, but thats kinda tricky with small LEDs and all....anyone???:shrug:
 
3 emitters would need to be very well heatsinked so somehow mounting them to a small D-26 sized bezel may not be ideal if the emitters are driven at higher current levels.

Have you considered a 3 emitter side shooter arangement? If you can get a good thermal path from the emitters to the metal flashlight's battery barrel then it could give you more latitude in a mod.

A "one size fits all" 3 emitter D-26 module isn't on the market because there is no way to ensure a proper internal heat sinking pathway with all the various lights that use D-26 sized lamp assemblies. Something like this would need to match the intended host flashlight really well, thermal pathway wise.

Have a look at the multi emitter prototypes that McGizmo created a while back.

The threeshooter seems less than ideal in terms of heat management... I guess a D26-module with a separate piece of copper machined to fit instead of the reflector would give a whole lot more thermal pathway than that solution....Just think about the amount of metal from base to front, and the LEDs just needs to be counterbored into the front of the module...it would be like filling an entire D26 with metal and just taking some off the top to fit the LEDs!
I´ll see if I can get time off to do the machinework in a few weeks...
