ACC is phasing out inefficient incandescent bulbs throughout the district.
In 2007 the federal government enacted the Energy Independence and Security Act, based on this act, inefficient incandescent bulbs will be phased out starting 2012 and ACC is stepping up to be ready for the regulation change and for the environment.
ACC had adopted energy efficient Fluorescent Tube Lighting and Compact Fluorescent Lighting (CFL) in most areas already. We will be phasing out rest of incandescent bulbs with the energy efficient CFL or LED lighting.
Fluorescent light bulb may contains small amount of mercury, proper disposal procedure is required.
This phase out plan won't affect the specialty lighting nor personal desktop lighting. If you have any questions or concerns, please send us an email to email@example.com
|Light bulb projected life span(hrs)||50,000 or longer||10,000||1,200|
|Watts per bulb (equiv. 60 watts)||8.6||10||40|
|Cost per bulb||$9.97||$3.50||$1.25|
|KWh of electricity used over 50,000 hours||430||500||2000|
|Cost of electricity (@ 0.10per KWh)||$43||$50||$200|
|Bulbs needed for 50k hours of use||1||5||42|
|Equivalent 50k hours bulb expense||$9.97||$17.50||$52.50|
|Total cost for 50k hours||$52.97||$67.50||$252.50|
Note: The re-lamping labor cost and the disposal cost were not factored in this comparison also it is expected that the LED bulb cost will come down significantly in the coming years.
