Almost 90 % of electrical energy provided to an incandescent light bulb goes as heat and rest as light. A 100 Watt bulb puts out 100 Joules of heat per second. So - for one minute it would put out 6000 Joules (100 Watts X 60 seconds). 1 BTU (British Thermal Unit) of heat = 1055.056 Joules. So a 100 watt bulb, burning for one minute would put out 5.68 BTUs of heat. ( 6000 Joules / 1055.056 Joules) = 5.68 BTUs. Same bulb burning for one hour would generate 341 BTUs of heat.

Can an incondescent lamp dimmer be used to control a fluorescent lamp load?
No, incandescent lamp dimmers are not compatible with fluorescent lamps. Fluorescent lamps require special dimming ballasts to control their light output. Attempting to use an incandescent lamp dimmer with a fluorescent lamp can cause damage to the lamp and dimmer.
Can we use fluorescent lamp in dc?
Yes, fluorescent lamps may be powered by DC but they need a DC lamp controller instead of an AC ballast and starter. The DC lamp controller is more complex. I have a 12V lantern with fluorescent lamp tubes.
If the ballast on a fluorescent light blows will the lamp still work?
Typically, if the ballast on a fluorescent light blows, the lamp will not work. The ballast regulates the electrical current to the lamp, so if it is not functioning properly, the lamp will not receive the correct power to light up.
How hot do fluorescent lamps get?
Fluorescent lamps can reach temperatures between 150-250 degrees Fahrenheit during operation. The heat is mainly generated by the electrodes and the ballast of the lamp. It is important to handle fluorescent lamps carefully to avoid burns.
How many lumens in a 26 watt compact fluorescent lamp?
A 26-watt compact fluorescent lamp typically produces around 1,700 lumens.
