Light bulbs always use energy. Therefore to save energy they should be switched off.
But certain types of bulb use much less energy than others:
Incandescent: 10 lumens per watt
Halogen: 13 lumens per watt
Fluorescent: 50-60 lumens per watt (cheap to buy)
LED: 50-70 lumens per watt (expensive to buy)

Does a light dimmer work with the new energy efficient light bulbs?
If you are looking to use the new energy efficient light bulbs on a light dimmer you will need to buy specially made dimmable CFLs. Not all energy efficient light bulbs are compatible with dimmers so be sure to check the packaging for information.
Can LED lights be used on a timer?
LEDs do not work on all timers. This is also the case with many energy saving bulbs. The timer lets enough voltage thru to partially light the LEDs and energy saving bulbs. LEDs will light fully when the timer is "on", but will continue to light dimly when the timer says "off". Energy saving bulbs will have a dim flicker when "off" thru a timer. I have not found a timer yet that solves this problem. If anyone knows of a solution I'd love to be able to use energy efficient lights with the convenience of a timer.
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 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.
Why are 92 Toyota corolla tail lights out but dash light work fuse is fine?
If your 92 Toyota Corolla taillights are out, but the dash light and fuse work fine, the bulbs could have burn out. Replace bulbs on each side.
Does a light dimmer work with the new energy efficient light bulbs?
If you are looking to use the new energy efficient light bulbs on a light dimmer you will need to buy specially made dimmable CFLs. Not all energy efficient light bulbs are compatible with dimmers so be sure to check the packaging for information.
Can any dimmer work with energy efficient bulbs?
Yes, if they replace the switch at the wall.
Why is the energy of a flashlight heat and light energy?
because old - style light bulbs work by passing an electric current through a thin piece of metal (tungsten is commonly used in these) to heat it up enough to make it glow. In these old - fashioned light bulbs, most of the input energy is given out as heat (about 95%) and the rest light. However, in new, so called,"energy efficient" light bulbs, an electric current is passed through different gases (including mercury gas) to make the particles collide with each - other and give out light. Depending what metal vapour you use determines the colour of the light given off. These are more energy efficient because about 60% of the energy given out is heat, and 40% light, so it isn't ideal, but is better than the old light bulbs. However, these new light bulbs might not be entirely benefitial as they are less cost - effective than the old ones. Written by a 12 - year old!
How does the light bulb impact us today?
Light bulbs have revolutionized society by providing artificial light that allows people to work and live comfortably even after dark. The invention of light bulbs has increased safety, extended working hours, and improved quality of life by enabling activities to take place at any time of the day. Additionally, advancements in energy-efficient light bulbs have contributed to reduced energy consumption and environmental impact.
How did Albert Einsteins light-bulb change or shape the way you live today?
Albert Einstein's work on light and energy led to advancements in technology like LED light bulbs, which are more energy-efficient and longer-lasting than traditional incandescent bulbs. This has had a positive impact on reducing energy consumption and carbon emissions, shaping the way we live today by promoting sustainability.
How energy saving light bulbs work?
Energy-saving light bulbs, such as compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs), work by converting electricity into light more efficiently than traditional incandescent bulbs. They produce less heat and use less electricity to generate the same amount of light, resulting in reduced energy consumption and lower electricity bills. This efficiency is achieved through the use of different materials and technologies that minimize energy loss and maximize light output.
Can LED lights be used on a timer?
LEDs do not work on all timers. This is also the case with many energy saving bulbs. The timer lets enough voltage thru to partially light the LEDs and energy saving bulbs.

Why don't people always use the most energy-efficient type of lighting?
Cost and aesthetics. Compact flourescent bulbs have an initial cost much higher than incandescent bulbs, though they are cheaper in the long run. CFLs also emit light that "looks" different than incandescent bulbs, and may not work for the desired application such as high intensity lights for work areas.
Do televisions use light bulbs to work?
No
What are dimmable light bulbs and how do they work?
Dimmable light bulbs are bulbs that can adjust their brightness levels. They work by using special technology that regulates the amount of electricity flowing to the bulb, allowing users to control the light intensity.
How do incandescent light bulbs work and what makes them different from other types of light bulbs?
Incandescent light bulbs work by passing electricity through a filament, which heats up and produces light. They are different from other types of light bulbs because they rely on this heating process to produce light, whereas other types, like LED or fluorescent bulbs, use different mechanisms to generate light.
Do bulb make use of magnets to work?
No, bulbs do not make use of magnets to work. Light bulbs function by passing electricity through a filament, which then emits light and heat. Magnets are not involved in the process of generating light in bulbs.
