Hello David

If you still have this setup, it would be verying interesting to 
compare these to a couple of Halogen Shop Lamps.  They usually have the 
best blue to red ratio, but it is usually still less than 1.



Thanks

To follow up on the discussion about GE Reveal bulbs, I used an ST-7E 
camera
on a DSS-7 spectrograph to obtain spectra for a 60W Reveal bulb and a 
60W
regular incandescent bulb, at full brightness and dimmed. The spectrum
images were reduced and calibrated using a Neon calibration lamp. The
spectra were generated using SBIG's Spectral Calibration Program.
