Mods, could you please move this to the Fixed Lighting forum? Thanks!
Thought some of you might find these interesting.
These are spectrums from a Gretag Macbeth i1 Spectrophotometer. The round graph on the right shows two spectrums. The thin black line is 'daylight', and the thicker red line is the bulb being measured. You can see color temp below that, and on the left, CRI. Ignore the illuminance, as I held the spectro varying distances from the light.
