Keeps my "pet" warm
I use this bulb in a non-traditional application: an under desk radiant heater for my wife. It provides a gentle warmth, so does not need a thermostat. At 100w I do not feel bad about leaving it on all day while she works. The service life seems to be 2-4 months, but at PetGuys prices, there's no comparison to the cost of 100w radiant panel heaters sold for under desk use.
No bright glare
Gentle, continuous warmth
ConsService life is somewhat limited.
