Ugh, physics gurus: Whats the correct conversion from lumen to candela? I've always thought it goes as follows: lumen is defined as candela/sr. Ok. So, for 18lm flux, the calculation goes as follows: 110 degrees (of 360) is 122.22222 in steradians. Ok. Then multiply the degree value w/flux totalling 2200 Candelas for 1W white Luxeon star in whole beam.
Huh?
