So what should you be looking for as you poke around the lighting shelves and find them now devoid of the old familiar light bulbs of yore?
For a start, low energy light bulbs currently come in two main forms: the fairly common CFL (Compact Fluorescent Lamp) which has been around a few years already; and the, as yet, less well known LED (
light emitting diode).
In terms of purchase price and availability, CFLs are the cheaper option and having been around longer are more ...

For a start, low energy light bulbs currently come in two main forms: the fairly common CFL (Compact Fluorescent Lamp) which has been around a few years already; and the, as yet, less well known LED (
Light Emitting Diode).
In terms of purchase price and availability, CFLs are the cheaper option and having been around longer are more plentiful. Compared to incandescent bulbs, CFL are about 4 times cheaper to run and last longer, but given that they are also presently twice as expensive to buy, ...
There are currently only three contenders to replace the antiquated incandescent light bulb: CFLs (compact fluorescent lamps); LEDs (
light emitting diodes) and HEIs (high efficiency incandescents).
That last one may seem an odd choice since an HEI light bulb is still an incandescent lamp, but the urgent global concern surrounding existing incandescent lighting isn't focused on the technology per se, but on the fact that all present ...
... considerably less energy to produce the light (or put another way, converting more electricity into light, rather than wasting it as heat).

Whether you look at a conventional incandescent GLS (General Lighting Service) bulb, a tungsten halogen lamp, the current generation of energy saving bulbs called CFLs (Compact Fluorescent Lamps) or a new generation LED (
light emitting diode) unit, almost all the cost of a light bulb is in the running costs. In other words the price of electricity. The cost of the bulb itself is quite marginal when calculating the cost of lighting.
Incandescent light bulbs waste well over 90% of their input energy as heat - only a small ...
... United States - that represents a huge opportunity to save electricity and a whole lot of money so becoming energy savvy is an all round savvy way to go.

Though the lighting industry is less than enthusiastic about CFLs, they do have a vision for the future of domestic energy saving lighting that (excuse the pun) lights the way forward. As far as the big names in the lighting industry are concerned the future is LED home lighting.
LEDs (
light emitting diodes) are a form of solid state lighting that has been around for quite a while in low power applications such as torches and night lights and so on. But with the new generation of low power consumption high brightness LED light bulbs combined with the urgent need to stop ...
