Throughout my home I have 72 CFL's of various wattages. Mixed brands,
most are indies. Color temp varies from 2700K to 2900K, equal to
incandescent. Have had 4 failures in 7 years, 2 outdoors and 2 in
basement. I think vibration may have got the outdoor ones as they are
post lights. The 2 in the basement are on 24/7 for general illumination
for cats to find food, water, and litter boxes.


I don't think that cats require any more light than a dim glow
(equivalent to moonlight/starlight.) They ARE basically nocturnal
animals, after all.

Green or blue LED nightlights rated to consume less than 1/2 watt will
be plenty. They produce light of wavelengths that night vision is
sensitive to. My experience is that even dark-adapted humans can see by
those well enough to easily find objects in rooms.
