Don't ask. Take it for what it's worth (not much, really).

Here are my light measurings, using a Canon IXUS 75 with CHDK, on a tripod, facing a white wall at a distance of around 30 cm. All the flashlights were held in the same position, at about 20 cm from the wall, so that the camera was looking at the complete circle of light. Here are the results:

flashlight: high / low
Surefire C2 with M60 and AW batts: 951,3
Surefire 6P with M60 and AW batts: 847,5
Lummi Raw NS R2 with 14250: 712,7 / 61,20
Fenix PD20 with primaries: 667,8 / 44,54
Surefire E2DL with primaries: 625,8 / 25,91
Novatac 120P with AW batt: 599,3 / 0,75
Nitecore EX10 Q5 with AW batt: 549,5 / 3,88
Surefire 6P with M60L, McC2s, AWs: 545,6 / 197,1
Nitecore DI R2 with lithium AA: 533,9 / 10,66
BitZ Pocket Al with AW batt: 493,1 / 35,10
Ra Twisty 100 Tw with AW batt: 445,7 / 1,21
Surefire E2L with primaries: 400,0 / 26,87
Surefire E1B with primaries: 351,2 / 20,57
Surefire L1 with primaries: 261,2 / 37,45
Surefire E1L with primaries: 218,1 / 17,93
Arc-P CS with lithium AAA: 61,20

Yep, you are my inspiration!:thanks:

Just didn't take the trouble to calibrate this time, I'm just starting out with these and with the runtime script.
