The light bulbs are sealed and do not directly give off carbon dioxide. However they require more energy than flourescent light bulbs for the same amount of light. And many of the original sources of the energy give off carbon dioxide when generating electricity. So indirectly, yes. What is not talked about very often is that many houses are electrically heated. In these houses, the lights contribute to the heating (what is not light is heat, roughly.) So in these cases, incandescent lights are 100% efficient and the net effect is that there is no difference in the total output of carbon dioxide with the same light/temperature in the house. Another consideration is that CFL / flourescent lighting may require more energy and resources to make, so incandescent bulbs may actually result in less CO2 production, but this depends on the periodicity of replacement and usage. In the U.S., breaking a CFL bulb is considered an unsafe Mercury spill site by the E.P.A. requiring 15 minutes of ventillation in the house and resources to clean up which could also be considered in terms of time, heating, and resources, all requiring CO2, but this last thought is just the author's jaded opinion, the former being science. Happy lighting :)
They don't. Carbon dioxide is given off by coal power plants, which provide somewhere between 40-60% of the worlds energy. You could argue from here that using a light bulb (or using energy in general) causes the release of carbon dioxide into the atmosphere, but the facts remain that light bulbs themselves do not do this.

What light bulbs provide the most natural light?
Any natural light bulbs that use incandescent lighting will work well, and give off a rounder light than the "sterile white" lighting of normal bulbs.
Which light bulbs give off all the colors of visible light?
Incandescent bulbs or if you prefer, plain old fashioned light bulbs, the ones with a filament (the bit of wire inside) that gets very hot and gives off light. They tend to give off a bit more at the red end of the spectrum, particularly the lower power ones but they do give off all the colours. Some run the filament at a sufficiently high temperature to give a pretty balanced white light. Most of the modern energy efficient bulbs give off light at a limited number of frequencies but much more light per watt of power that goes in.
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.
What are the advantages and disadvantages of using compact fluorescent light bulbs?
One nice thing about light bulbs is that they provide light indoors and when it is dark outside, without having to light a candle or an oil lamp. They are also relatively safe, clean and easy to operate. Disadvantages include the fact that you will need electricity and wires that are properly installed and cannot be easily moved about. It is also difficult to repair a broken light bulb or one that has burned out, and they must be disposed of and replaced.
Does the temp affect how light bulbs evaporate water?
The light bulb increases the temperature, and the higher the temperature, the faster evaporation occurs. The light bulb itself doesn't evaporate water. If you're using the old incandescent light bulbs, they will give off a lot more heat, and evaporate more water than an energy-saving bulb. It also depends on the distance between the bulb and the water, the surface area, mass of water, and time.
What kind of light bulb gives off the most heat?
Incandescent light bulbs give off the most heat compared to other types of light bulbs because they produce light as a byproduct of heat. This is due to the way they function by passing an electric current through a filament, which heats up and emits light.
Does a 40 watt G9 Xenon bulb give more light than a standard 40 watt incandescent?
Yes, a 40 watt G9 Xenon bulb typically gives off more light than a standard 40 watt incandescent bulb. This is because xenon bulbs are more efficient and produce brighter light for the same wattage compared to incandescent bulbs.
What light bulbs provide the most natural light?
Any natural light bulbs that use incandescent lighting will work well, and give off a rounder light than the "sterile white" lighting of normal bulbs.
What is the wire that gives off light in a light bulb?
In an incandescent light bulb the wire that gives off the light is called the Filament.
How can you conserve energy at home?
You can replace your incandescent light bulbs with compact fluorescent bulbs, turn off the light when you leave the room. You can turn the water off when your brushing your teeth, and take faster showers.
Does a 60-watt electric light bulb create heat energy?
Yes. Part of the energy is converted to light, part to heat. The percentage depends on the type of light bulb. Fluorescent and LED light bulbs are more efficient than incandescent light bulbs. A 60-watt incandescent bulb will be uncomfortable to remove from the socket with your bare hands after turning it off. However, a 100-watt bulb will burn you if you remove it with your bare hands after turning it off.
Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?
A compact fluorescent light bulb typically lasts longer than an incandescent light bulb. Compact fluorescent bulbs can last up to 10 times longer than incandescent bulbs due to their more efficient design and reduced heat production.
What is filament coil?
it is the coiled wire that heats up and gives off light in a incandescent (ordinary) light bulb.
Which light bulbs give off very little energy as infrared rays?
LED light bulbs give off very little energy as infrared rays compared to incandescent light bulbs or halogen light bulbs. LEDs are more efficient at converting energy into visible light, resulting in lower heat output in the form of infrared rays.
Most of the energy of an incandescent bulb is given off as?
Most of the energy of an incandescent bulb is given off as heat rather than light. Incandescent bulbs are not very energy efficient compared to other types of lighting, as they convert a large portion of electrical energy into heat instead of light.
Do incandescent bulbs give off a lot of heat?
This is a trick question because the person asking it expects you to not know much. He or she is expecting you to say 'yes, because its too hot to touch'. But really, there are many many things that need to be considered when you say 'a lot of heat'. If you are comparing incandesent bulbs with florescent bulbs that give off the same amount of light measured in lumens, at say 20 degrees celcius, then answer is that the incandescent bulb gives off more heat. But if you vary the size of the bulb, the shape of the bulb, the location of the bulb, the environment of the bulb, the wattage of the bulb, or many other things, you can have an incandescent bulb that does not 'give off a lot of heat'.
