OK, I've been taking and reporting various lights readings for sometime now. The numbers I usually report are not important as it relates to FC, LUX, Candlepower, Etc, but are used for comparision puposes of two or more lights. I have a variety of ways I obtain those numbers, by sometimes putting the light right on the sensor, or sometimes using a white plastic cylinder to lessen the output for lower numbers, etc.
I'm curious to hear how you folks take your measurements and more importantly the "standards" for measuring light output in FC, LUX, ETC. There has to be some written method, so when Joe Blow says he light puts out 500 lux, it actually means something.
