To LumensFactory,

The claim has been made by some, including our much esteemed MDOCOD (Valued contributor at CPF), that SureFire must be updating their lamp technology to keep up with the state-of-the-art, and that their lamps should be very high-pressured also - the key difference being that SureFire doesn't drive their lamps as hard and thus SureFire lamps last longer. Some people here at these forums are also applying the following formulas to try to equate "LumensFactory Bulb Lumens" to "SureFire Torch Lumens," and that is multiply the LumensFactory bulb-lumens by .65 to acheive regular torch lumens, then multiply further by .80 to yield the de-rated average torch lumens provided by SureFire. This formula when applied to the SR-9 yields 220 X .65 X .80 = 114 SureFire Lumens. As the SureFire P90 is spec'd at 105 SureFire Lumens, this is an increase in only 9% efficiency.

My question to you is, how do you see your efficiency (as provided by your 8 atm xenon pressure and robust filament design) as compared to SureFire, and can you quantify, or estimate, what you feel this efficiency is?
