Famous for its inefficiency, incandescent light bulbs held on to their market share for years for one reason: they were cheap. Not cost-effective, just cheap — and people were accustomed to the quality of the light. Incandescent lighting converts most of it’s energy to heat, the infrared part of the spectrum, with only about 2-3% converted to visible light.Incandescent bulbs are scheduled to be phased out in the US, but the marketplace is making alternatives far more cost-effective well in advance of the federal timetable.
The compact fluorescent light (CFL), once shunned for its long warm-up time, awkward size, and undesirable bluish light, can now be found to fit every type of socket, and the light itself can be sharp and blue, soft and golden, or similar to bright daylight. Each CFL that replaces a regular incandescent light bulb can save you $6 a year in electricity costs and can save more than $40 over its lifetime. Furthermore, they use about 75% less energy than a traditional incandescent bulb and last at least 6 times longer. They also produce about 75% less heat, so it’s safer to operate and can cut home cooling costs. Price reductions are making CFLs comparable to or, in some cases less expensive than, standard incandescent bulbs.
Newer but still relatively expensive LED lighting is being used with photovoltaic systems because of it’s extreme efficiency and in difficult to reach lighting locations because of its long life. LED are also being incorporated into replacement bulbs for home lighting. LED bulbs are more than twice as efficient at CFLs, and unlike them, LEDs turn on quickly and are compatible with dimmer switches. As their price comes down, they will become more cost effective for residential applications. Contact us today to speak to an EDGE Energy expert to find out the best type of lighting for your needs.
