Par Lights are a Popular Lighting ChoicePosted by admin on Jul 21, 2010 in LED Par Bulbs | 0 comments
DOE estimates of U.S. Lighting Market Characterization suggest that there are close to 350 million incandescent recessed lights in operation of which 76% are in the residential sector. Different types of bulbs can be used in recessed lights. Here is a description of some of the most common types of bulbs to help you make an informed choice.
A few simple calculations demonstrate the impact that PAR lights can bring about. The table below shows a base case scenario if incandescent PAR lights are replaced with Energy efficient LEDs.
|Variable||Residential Sector||Commercial sector||Total|
|Average daily operating hours||2.3||10|
|Peak coincidence factor (% on at peak)||7||75|
|Average operating cost||0.1||0.1|
|Installed base (Millions)||265||85||350|
|With traditional Halogen Lamps|
|Lamp wattage (Average)||73||73|
|Annual kWh (millions)||16240||22648||38888|
|Peak demand (MW)||1354||4653||6007|
|Annual operating cost ($ Million)||1624||2264||3888|
|With energy efficient LED Par lights|
|Lamp wattage (Average)||12||12|
|Annual kWh (Millions)||2669||3723||6392|
|Peak demand (MW)||222||765||987|
|Annual operating cost ($ Million)||266||372||639|
|Savings ($ million) in operating costs from LED PAR lights||1357||1892||3249|
|Reduction in peak demand (MW)||1131.55||3888.75||5020.3|
All the data used in the analysis above is in the public domain and anyone can draw up his own spread sheet. The figures may vary a bit but the conclusion will always be the same. Reducing energy consumption is the prudent choice. An annual saving of $ 3249 million is no small figure. Neither is the projected reduction in peak electricity demand. Installation costs of each additional KW of fresh electricity generating capacity range between $ 2700 to 6000 per KW. Given that peak electricity demand can be reduced by 5020 MW the savings in installation costs alone would be of the order of 15000 to 25000 million dollars. The high cost of adding new generation capacity is the reason why many utilities encourage customers to reduce their energy consumption by giving rebates and educating them about energy efficiency. Energy efficient products have another advantage. They help bring productive, high value jobs back to United States. These are some of the reasons why MyLEDLightingGuide is committed to a greener future.
