I always made sure that I had a 100 watt bulb to read by but they were so hot during the summer, now I use 100 watt equivalent bulbs, cool white, which makes the print clearer than incandescent, and I use a few 300 watt equivalents to really light up my place, I like that they don’t heat up the house and they last for so many years, I have yet to learn how many years they will last.
Fun Fact .... the original filament light bulb is STILL burning!! ...
Yes, the famous Centennial Light bulb is still burning today.
Details of the BulbLocation: Fire Station 6 at 4550 East Avenue in Livermore, California.
Age: It was first turned on in June 1901, making it over 125 years old.
Manufacturer: Hand-blown with a carbon filament by the Shelby Electric Company in Ohio during the late 1890s.
Current Output: Though originally rated at a higher wattage, it now glows very dimly at about 4 watts—the light level of a small nightlight.
Why Has It Lasted So Long?
Thick Filament: Its carbon filament is much thicker than those used in later incandescent bulbs
.Low Power Operation: Running on a low-wattage circuit reduces stress on the internal parts.
Continuous Power: It has rarely been switched off, avoiding the thermal shock of frequent power cycles that break modern filaments.
