HOW DOES LED LIGHTING WORK?
LED stands for light emitting diode. LED lighting products produce light approximately 90% more efficiently than incandescent light bulbs, and emit much less heat into the living space. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light. LEDs produce a pleasing light that is easy on the eyes, similar to incandescent bulbs and much less harsh than compact fluorescent lighting (CFL).

LEDs PROVIDE EXCELLENT COST SAVINGS
LEDs provide significant energy savings versus traditional incandescent bulbs and decent increased savings versus CFLs. However, when considering LEDs versus CFLs, it is important to consider the expected useful life of the two types of bulbs. The useful life of LEDs is three times longer than CFLs. Therefore, LEDs are the best long-term investment with regards to cost savings, especially when you factor in the labor needed to install replacement bulbs.
The table below is meant to illustrate cost and energy savings for a typical American home, which, on average, uses 40 light bulbs per home.
CAHP 100% LED LIGHTING KICKER AND EDR BONUS
CAHP participants who install 100% LED lighting receive a 0.5 Delta EDR increase for inland climate zones, and a full 1.0 Delta EDR increase for coastal zones. Remember, CAHP rewards projects that push for deep energy savings, so an increase of 1.0 EDR point translates to an additional $150 per unit for projects that have a Delta EDR of 3 through 6, and $300 for a score of 7 or above.
CAHP provides additional kickers for high-performance design and installation of other energy efficient features. When you earn multiple kickers on the same project, they can significantly increase your per unit incentive – up to $2,200 per unit for coastal, and 1,900 for inland in addition to your base performance incentive!
