Many cities and neighborhoods are adopting initiatives to encourage quality lighting that helps maintain our view of the stars at night.
Hire electric can help you retrofit or install new lighting that saves you money on your electric bill AND makes your property more secure.
The key is not to waste light that is going where you don’t need it – like up. The basic rule of thumb is to have a lens or reflector that hides the bulb and provides a full cut off at horizontal. This lens will point the light down at the things you need to illuminate and not out into your neighbors windows, eyes or the heavens above.
The other factor that helps comply with Dark Sky initiatives is the temperature of the light. Light that is very blue or white tends to reflect more off surrounding objects and dilate the eyes in ways that make them less effective for night vision. A kelvin (temperature) rating of less than 3000 is recommended. LED magazine article.
In many cases a lighting upgrade can meet both the goals of Dark Sky compliance and energy efficiency. The energy efficiency piece has incentive programs through most utilities (especially for businesses) that help with the upfront cost. We have helped many local gas stations convert to LED lighting with the power company paying for almost half the project cost. Customers love the new look, the lamps last forever (almost) and the electric bill is cut by 75%.
