No, that is a rumor. It is simply not POSSIBLE for a fluorescent light-bulb, for example, to use the energy equivalent of one or two hours of normal use within the few seconds it takes the bulb to turn on - that would create such a large current that it would immediately trip the fuse. Some devices may use some extra power when turning on, but that is only perhaps 2-3 times the normal power consumption - not the equivalent of hours of normal use within seconds!
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
For Fathers Day 2011, think about eschewing the typical gifts and giving your dad something more practical. Change out all of the light bulbs in his home with energy efficient bulbs. Because energy efficient light bulbs use much less power than incandescent light bulbs, a house full of them will drop utility bills dramatically. When choosing energy efficient bulbs for Fathers Day 2011, you will have three options. First, you can swap out the bulbs for fluorescent lights. Fluorescent lights are inexpensive, but you will more than likely have to change out all of the lamps and lighting fixtures since the bulbs are not compatible with lamps that take incandescent bulbs. Next, you can opt for the compact fluorescent lamp (CFL) bulb, which are fluorescent lights that are made to fit into traditional light bulb receptacles. Not only do these bulbs use much less energy than regular bulbs, but they will also last much longer, saving your father money in the long run. Finally, you can choose to buy light emitting diode (LED) bulbs, which are also energy efficient. Because these are new, they are more expensive on the front end, but will last longer than CFL bulbs as well as use less energy.
Same as at home, or anywhere else. Basically, use energy-efficient light bulbs, and turn off lights you don't need (for example, when the last person goes out of a room).
Yes A 100watt light bulb left on for 10 hours will use a much electricity as a 1 Kilowatt fire left on for one hour. An energy efficient light bulb giving out the same amount of light as a 100watt bulb, only actually uses 20watts of electricity. That is 1/5th of the electricity, it will need to be on for 50 hours to use as much as a 1 Kilowatt fire left on for one hour. This will reduce your electric bill but the bulbs are more expensive than old 100watt bulbs (but the energy efficient bulbs last 6-8 times longer! so this balances out).
The energy put into the bulb is converted to heat and light. Low-energy bulbs just use less electrical energy to keep them bright.

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.
Energy efficient light bulb saves half of energy consumed by a regular bulb, although it has a lower range light compare to the high energy consumer 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.
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
Compact fluorescent light bulbs are pretty energy efficient and are energy star rated.
LED light fixtures are made out of clusters of very small, super energy efficient bulbs. Because many of those bulbs are used, LED lights can be built to mimic the effects of regular incandescent bulbs. A huge part of what makes LED bulbs so energy efficient is that they do not produce heat as incandescent light bulbs do.
There is actually no energy efficient light bulbs in a way to interpret in physical determination. Energy efficient means less Watts required per hour compared to non energy efficient.
comparing to the traditional light bulbs energy efficient fluorescent light bulbs uses 25% to 75% energy and saves money also and it lasts up to 3 to 25 times long so there is no need to replace energy efficient fluorescent light bulbs often.
LEDs are definitely better than the ordinary light bulbs because they're more energy efficient, and you'll be able to get a lot of savings since you don't need to change your bulbs every now and then.
Energy efficient light bulbs can be easily recognized, as they are each given an "ENERGY STAR" label. They can be purchased at a wide variety of retail locations, including Walmart, Target, Home Depot, or Lowe's.
no not at all very expensive
