A Low energy bulbs uses about 1/5 energy of a traditional bulb.
ie. 20w (Low energy bulb) = 100w (standard filiment bulb)
80%+ traditional bulb s' energy is lost as heat.
The 20% figure shown above only relates to the low energy bulb during its normal usage. The question was about the overall ecological balance, which includes ecological burden through manufacture, distribution and disposal (or recycling). Low energy light bulbs contain heavy metals, electronics and toxic materials, and are manufactured (and recycled) using much more complicated and, presumably, more ecologically damaging processes compared to those involved in traditional tungsten filaments.
The question is still open thus.
From most energy efficient to least energy efficient:
LED bulbs (relativly new)
Fluorescent bulbs (normal "energy savings" bulbs)
Halogen (used for high intensity lighting)
Incandescent bulbs (regular bulbs)
Energy efficient light bulbs are bulbs that convert a higher percentage of electical power into light. All bulbs also create waste heat, where energy is radiated as infrared. The less efficient bulbs tend to be "hotter" because of the amount of power "wasted" this way.
they last longer and use less electricity thus making your bill smaller
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.
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.
LED lights are better than bulbs because they are more energy efficient, and environment friendly. You can definitely get a lot of savings with LED light bulbs.
E14 Light bulbs have an advantage over traditional light bulbs. They are designed using LED lights. These lights emit more light (making them brighter) and energy efficient capable of reducing your total energy costs when compared to traditional light bulbs.
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.

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.
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.
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.
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
Energy efficient table lamps are available in many online shops such as LampPlus and YLighting. Lamps can even be made energy efficient by changing the light bulbs to fluorescent spiral bulbs.
