Energy Efficient Lighting

 

Electric lighting burns up to 25% of the average home energy budget.

The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself.

Light Emitting Diode (LED)  bulbs and fixtures have revolutionized energy-efficient lighting.


LEDs are small, very efficient solid bulbs. New LED bulbs are grouped in clusters with diffuser lenses, which have broadened the applications for LED use in the home. LED technology is advancing rapidly, with many new bulb styles available. Initially more expensive than CFLs, LEDs bring more value since they last longer. Also, the price of LED bulbs is going down each year as the manufacturing technology continues to improve.

 

LEDs (Light Emitting Diodes) are solid light bulbs, which are extremely energy-efficient. When first developed, LEDs were limited to single-bulb use in applications such as instrument panels, electronics, pen lights and, more recently, strings of indoor and outdoor Christmas lights.

 

Manufacturers have expanded the application of LEDs by “clustering” the small bulbs. The first clustered bulbs were used for battery-powered items such as flashlights and headlamps. Today, LED bulbs are made using as many as 180 bulbs per cluster, and encased in diffuser lenses, which spread the light in wider beams. Now available with standard bases, which fit common household light fixtures, LEDs are the next generation in home lighting.

 

A significant feature of LEDs is that the light is directional, as opposed to incandescent bulbs, which spread the light more spherically. This is an advantage with recessed lighting or under-cabinet lighting, but it is a disadvantage for table lamps. New LED bulb designs address the directional limitation by using diffuser lenses and reflectors to disperse the light more like an incandescent bulb.

 

The high cost of producing LEDs has been a roadblock to widespread use. However, researchers have developed a process for using inexpensive silicon wafers to replace the expensive sapphire-based technology. This promises to bring LEDs into competitive pricing with CFLs and incandescents. LEDs will soon become the standard for most lighting needs.  Contact Ring Electric today to discuss LED lighting options for your home or business.
