Re: [APD] Lighting Comparison
I have never seen the answer to this anywhere. My memory is that the
2 wpg number started to be used when only T12 bulbs were in use, and
with white painted flat "reflectors". Clearly 2 wpg of compact
fluorescent bulb light in an AH Supply reflector is a lot more
light. So, this is an excellent question.
