Depends upon the wattage rating. A 24 watt bulb will create far less heat energy than a 100 watt bulb.

Why is an incadescent bulb a very inefficient light source?
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
What kind of light bulb gives off the most heat?
Incandescent bulbs produce the most heat for a given amount of light; fluorescent lights produce much less heat, and LED produces the least.
What light is better a fluorescent light or incandescent light to grow a plant?
Definitely fluorescent. Incandescent lights are extremely inefficient and spend most of their energy producing heat rather than light. This is why an incandescent lightbulb gets so much hotter than a fluorescent one.
Do CF light bulbs produce as much heat as incandescent bulbs?
No, compact fluorescent bulbs run much cooler that an incandescent bulb. A CF bulb can be unscrewed when the lamp is on whereas an incandescent will give you a bad burn if this is tried.
How does the incandescent light bulb work?
Current passes through the filament of the bulb causing it to heat up. When it heats up, it becomes so hot it incandesces. That means it radiates light. When the filament is white hot, it radiates light across much of the visible spectrum. Incandescent lights also waste a lot of energy which comes out as heat.

Why do incandescent light bulbs waste a lot of electricity?
Because they give off much of their energy as heat due to how the metal filament works

How much of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
Why do incandescent light bulbs waste a lot of energy?
Any form of electrical lighting will produce both light and heat, and with inefficient, incandescent lighting you get a higher proportion of heat rather than light, as compared to other forms of lighting such as fluorescent, or the most efficient, which is LED, which turns almost all of the electric power that it consumes into light, and very little into heat.

No, compact fluorescent bulbs run much cooler that an incandescent bulb. A CF bulb can be unscrewed when the lamp is on whereas an incandescent will give you a bad burn if this is tried.

Why does energy saver give more light than electric bulb of same watt?
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
Why is fluorescent lighting better for an aquarium than incandescent lighting?
An aquarium is sensitive to temperature changes. Incandescent lighting gives off much more heat than fluorescent lighting.
Are light bulbs really efficient?
Normal incandescent bulbs produce a lot of heat as well as light, so are not so efficient as low energy bulbs which can give the same light but consume much less electricity
What type of energy is heat?
Heat is thermal energy. It is pretty much the same thing as thermal energy.
