What Is It?

Energy efficient lighting refers to energy-saving alternatives to incandescent light bulbs and their fixtures, which are commonly found in residential, commercial, and industrial settings. Popular alternatives to incandescent sources are compact fluorescent light bulbs (CFLs) and light-emitting diodes (LEDs). Energy efficient lighting strategies also include upgrading fluorescent bulbs (or tubes) to newer, more efficient bulbs and ballasts (especially from T12s to at least T8s, and preferably T5s, which use much less energy to produce the same amount of light) and incorporating natural light sources.


According to the EPA, an ENERGY STAR-qualified CFL will save about $30 over its lifetime and pay for itself in about six months. CFLs use 75 percent less energy and last about 10 times longer than the average incandescent bulb. ENERGY STAR LED products use at least 75 percent less energy and last 35 times longer than incandescent lighting. Qualified LED lighting produces virtually no heat and provides optimal light color for any environment. In addition, since these lights last longer and generate less heat, maintenance costs associated with changing out bulbs is greatly reduced and cooling costs can be reduced as well.
