Ive been setting up candles  and modeling the light source as a sphere
(apparently accurate enough) but after researching through several of
peoples papers on using candles in Radiance i found sets of RGB values.
 
Beeswax 0.502 0.239 0.043
Tallow 0.759 0.240 0
 
But when i use these as my material then apply them to a sphere of size
approx 0.01 they dont appear bright at all, in fact radiance doesn't
appear to light at all with them, decimal values for rgb are way to low.
The values i need are up in the 100's but how can i find out a candles
watts/steradian/m2 RGB values? does anyone have any as reference or know
of any?
 
Cheers John
