Energy Efficient Lighting
Are you still using incandescent light bulbs? These light bulbs waste up to 90% of your hard earned electricity in the form of heat loss. More efficient alternatives to incandescent light bulbs, include fluoresents, halogens and LEDs. These light bulbs are more efficient because they use less energy for the amount of light they produce. Lighting in your home accounts for up to 10% of your total energy use, so it is worth making a little change to save money and the environment. Not only will changing your light bulbs help you save, but a few small changes in your life style can as well. Comparing the Competition: Lamp Price Lamp Life Incandescent $0.75 to $2.00. 750-1,500 hrs Compact Fluorescent $4.00 to $20.00 6,000-15,000 hrs Linear Fluoresent $3.00 to $6.00 10,000-20,000hrs ***Watt – quantity of electrical energy used.
Light Output per Watt 8-20 lumens 36-70 lumens 20-90 lumens
Others: Halogen lamps have a long lamp life but they are only marginally more efficient. Recently light emitting diodes (LEDs) that use 95% less energy than incandescent have emerged, but are currently relatively more expensive. Conclusion: Since fluorescent lights use less energy, last longer, and save more money over time, they are the best choice. What are Fluorescent Lights? Fluorescent lights come in two types: as long, linear lamps, like those found in schools and grocery stores or as compact lamps that will fit in standard light fixtures. You are most likely not to use linear lamps because they require installation by an electrician. But, most Compact Fluorescent Lights (CFLs) fit in normal fixtures and come in a variety of shapes and sizes.
**Myth: “CFLs are not bright enough” – CFLs can be bought at many levels of brightness (lumens)
***Fluorescent lights do contain small amounts of mercury that pose no threat unless the light is broken. The light
bulbs should be taken to recycling facilities or disposed of as hazardous waste. Although CFL's have these handling and disposal issues, the energy savings of CFLs compared to incandescents have a greater overall environmental benefit.
The Things You Can do: • Replace your incandescent lights with fluorescent lights
o When Buying: always compare in lumens not watts, because these new lights use less “watts” but can produce equal if not brighter output.
• • • •
TURN OFF lights when you are not using them and use timers if you will be away Prevent overlighting of rooms by using lower-wattage bulbs Clean light fixtures Use natural sunlight when you can
