somewhere in the middle...I upgraded the SureFire 6P with a Malkoff 240 lumen LED conversion last summer, but was introduced to SolarForce(Hong Kong) LED upgrades for the SureFire incandescents I had picked up off prize tables... the G2 Nitrolons (top example) has a 320 lumen upgrade for about $11... I'm so far impressed with the center light from one of their bodies (only) ... the $11 320 lumen module + a $12 body +$5 worth of CR123's give you a pocket flamethrower for less than $30.. I accidentially flashed myself with it, and was disoriented for at least 3 minutes... the SolarForce upgrades do not have the heat sink of the Malkoff, and are more center weighted.
