My wife is an artist. Other than sunlight, she has found natural spectrum incandescent lighting to offer the most accurate color spectrum when working. I am a stamp collector (yeah, there are still a few of us) and most other lighting does not allow for accurate coloration when trying to identify older stamps. We also have solar tubes in her 'studio' which provide wonderful lighting on sunny days, but not so much on cloudy days or at night. Also, solar tubes allow heat into the room which necessitates the use of air conditioning during the summer, beyond what we might normally use, altho' we do cover them when not needed.
It is my plan to stock up on light bulbs against the day when they are no longer available, use them as long as possible, and damn the nanny state.
