What can covert electrial energy to light energy?
Ordinary light bulbs, fluorescent tubes, CFLs, flashlight bulbs, LEDs, toaster elements, and laser diodes all do that.
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.
Do you need special light bulbs for dimmer switches?
If you are using what most of us think of as a normal light bulb, what is called an incandescent bulb, you do not need special bulbs. Any fluorescent light bulb, including the new curly bulbs called CFLs, requires a special ballast. The ballasts are built into the CFLs so you would need to buy bulbs specially labeled for dimmers. Never place a dimmer on a fan, or any motor, unless it is specifically labeled for use with a dimmer.
What are the benefits of CFL light bulbs and how can it be maximized?
the benefits of CFLs can be maximized by were you put them you should always put them in high usage areas vea the kitchen
What is an example of common technology that does not efficiently convert energy?
Incandescent light bulbs are inefficient at converting energy into light. They are so inefficient that in many places there is no a ban on the sale or manufacture of incandescent light bulbs in favor of higher efficiency CFLs, LEDs, or halogen lights.

Replacing Old Light Bulbs with CFLs?
Upgrading to an energy smart home starts with replacing all of the old incandescent light bulbs with compact fluorescent lights, commonly abbreviated as CFLs. When buying new light bulbs, the most important specifications to look for include luminosity, bulb life, and power. The intensity of the light is measured in Lumens while the power is rated with Watts. In general, a CFL with about five times lower watt rating than an incandescent bulb can offer the same luminosity as the older bulb.
Does energy efficient light bulbs produce less amount of heat than non-energy efficient light bulbs?
Yes, non energy efficient bulbs like the incandescents waste around 90% of there energy in the form of heat. LEDs and CFLs don't even come close.
What are the pros and cons of a cfls light bulb?
Compact fluorescent light bulbs are cooler, use less electricity, and last a great deal longer than incandescents. However, they are more expensive than incandescent light bulbs and do contain trace amounts of mercury. They also have a slight delay before turning on.
What type of lights do you use that waste a lot of energy?
The type of light bulbs that waste the most energy are incandescent bulbs. They are least efficient because around 90% of the energy is lost on heat. They are also the shortest-lived light bulbs. The most efficient lights are LED lights, followed by CFLs, followed by the new Halogen incandescent bulbs. See the related link below for more information.
What percentage more efficient are CFLs?
I think it is 80% than the others
What are light bulbs that save energy called?
EcoSmart, ArmorLite, Philips, GE, and Sylvania all make a line of energy saving light bulbs. They all manufacture LEDs, CFLs, and halogen bulbs. All of these bulbs are comparable in performance and all of these products are energy savers.
