Lighting accounts for about 7% of a home’s energy costs. CFL bulbs use 66% less energy and last up to ten times as long as incandescent bulbs. They now come in a range of sizes, so they’ll fit almost any type of fixture, and styles, including full-spectrum, which mimics natural sunlight.
Test out one of each – Soft white, Daylight, and Bright White, and see which ones work best in your house. Traditional incandescent bulbs use more energy because the majority of electricity generates heat vs. light. Also consider choosing the CFL bulbs that have a ‘covered’ dome over the spiral bulb for safety and a better looking fixture – especially for recessed lighting.
Sample performance: Replace 20 incandescent bulbs that are 60 Watts with a life expectancy of 1,500 hours, with CFLs that only use 14 Watts and last 8,000 to 10,000 hours.
The ROI Calculation is based on replacing 20 bulbs that typically burn 750 hours per year with dimmable CFLs that cost between $1.00 and $3.00 and the average cost of electricity that is $2.76 per day. Each bulb saves on average $4 to $7 per year. Dome ‘covered’ and Dimmable CFLs are still higher in cost than the ‘corkscrew’ typical models, so the Light Emitting Diode (LED) market is picking up traction quickly. LEDs also do not contain mercury and they last between 50,000 and 80,000 hours!
Aircraft lights make it easier for birds to see and avoid aircraft, possibly helping to reduce the risk of bird strikes, according to a report recently published in the Journal of Applied Ecology. Scientists from the U.S. Department of Agriculture, Indiana State University and Purdue University tested the response of Canada geese to three remote-controlled aircraft — one with lights off, one with lights on, and one painted to resemble a bird of prey. They found geese responded more quickly to avoid the aircraft with its lights on. The research “could set the aviation industry on the right track to developing lighting systems that will reduce the rate of bird strikes,” the report said.
Currently, most efforts to control bird strikes focus on removing birds from the airport environment, according to the report. However, many encounters between airplanes and birds — including the most famous, US Airways Flight 1549, which ditched in the Hudson River after bird strikes killed both engines — occur far beyond the airport perimeter. The researchers hope to expand their study to other species besides Canada geese, so they can design aircraft lighting that will be seen by a wide range of birds. “This is only the first step,” said Bradley Blackwell, of the USDA National Wildlife Research Center. “As well as lighting, we also want to understand how to manipulate aircraft paint schemes so that birds find them easier to detect.”
