The light bulbs are very inefficient and get very hot. Most of the energy produced by conventional light bulbs is wasted in heat. The same light output as a 60 Watt bulb is achieved by most LEDs.
Is it normal for a light bulb to get very hot?
There are a number of things that can cause a bulb to burn hot. If your bulb is overheating, try to use a bulb with a lower wattage, and make sure you are using the correct voltage in light fixture.
How hot are light bulbs supposed to get?
The 60- watt bulb is able to get up to 200F on the glass surface. 70% of heat is produced by the fluorescent 60 watt. Most of the time, a standard bulb has less than 10% that is typically emitted. The bulb is warm to the touch between 50 and 60 degrees.
