I have a few beamshots sessions over at CPF showcasing the most powerful mods in a SureFire host. Yes, I typically play with the high output, poor runtime incandescents, but am no stranger to LED modules either. Your very best bet for high output and long runtimes in a SureFire w/ a single emitter would require custom fabrication from CPFer Milkyspit member and require:

1. Seoul P7 Tower Module + SureFire M6 (bored reflector) + FM 3x17670 (paralleled contacts) + Pila 600S x 3. In direct drive, think 800-900 lumens for 4500mAh / 2800mA = 1.60h * 60min/h = 96min runtime.

2. Seoul P7 Tower Module + SureFire M4 (bored for 18mm cells & bored reflector) + Pila 600P x 2. In direct drive, think 800-900 lumens for 4400mAh / 2800mA = 1.57h * 60min/h = 94min runtime.

Or you can opt for a Milkyspit multi-Cree (throw), or multi-P4 (flood) solution. A simpler, off-the-shelf option would entail:

1. SureFire C3 (bored for 18mm cells, or not) + Pila 300S x 2 (or Pila 300P x 2) + Malkoff M60 (or M60L, M60LL, or M60F, depending upon desired application)

For superior throw to any of the Malkoff modules, go with the following:

1. SureFire C3 (bored for 18mm cells, or not) + Pila 300S x 2 (or Pila 300P x 2) + Dereelight 1SM-2

Else wait for the SureFire UA2, or UB2, both of which are to be fitted with the P7 <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> .
