It seems to me it would be possible and desireable to have a standard flashlite rating system that would describe the characteristics of (most) flashlights. In fact, I bet if such a rating service were available, all the "serious" manufacturers would pay to get rated. I envision the following:
1. A physical description of the light.
2. An line graph of overall lumen rating vs time over the life of one set of batteries.
3. A color temperature rating vs time (as above).
4. A bullseye graph of the beam at some fixed distance, with fresh batteries, showing Lux ratings for each of several concentric circles - kind of like shotgun patterning.
I think this information would describe much of what most "light sensitive" people would like to know. It sounds like it might be a nice little business for someone with a few bucks and the technical know-how.
