“Did you know that the clear bulbs last much longer, but radiate more heat. (the reason they last longer) The inside frost light bulbs hold the heat within the bulbs and run hotter.”
What you say makes sense. I ordered Sylvania and GE 40s and 60s with inside coating for regular purposes. Ordered GE clear 40 ceiling fan bulbs. I need all the light I can get close to my chair to have plenty of light and they do stay on all day until I go upstairs at night. I replace them regularly. The GE ceiling fan bulbs say they last 2 and one half times than other fan bulbs. I just had to have that type bulb and a bunch of them.
OK, now ceiling fan bulbs have another issue. Heat rises, and it heats the base of the bulb. Many of the good ceiling fan bulbs have a brass base and the cement is more heat resistant than standard bulbs. The Brass base handles the extra heat much better than aluminum.
