    Use energy-efficient lighting in at least 75% of your lighting fixtures

    Fluorescent lights use up to 75% less energy than incandescent light bulbs, and can last up to 10 times as long. If you replace 20 bulbs with more energy-efficient lights, you can save up to $600 over the lifetimes of the bulbs. Compact Fluorescent Bulbs (CFLs) now come in all shapes and sizes. There are dimmable models, and models for recessed or outdoor lighting. Light Emitting Diode (LED) lighting is even more efficient than CFL lighting, but with a greater up-front cost.

    Learn more about ENERGY STAR® light bulb options.

    If you need help selecting the right bulb replacements, smart phone apps like Light Bulb Finder can help you to choose the right bulbs to upgrade.

    Save on upfront costs by taking advantage of Potomac Edison’s lighting rebates.

    If you tried a CFL and didn’t like it, it may be because you didn’t select the right wattage, color, brightness, or size. When purchasing CFLs, use these equivalencies to get the brightness you are looking for (or roughly divide by 4):

    Incandescent CLF
    60 Watt 13 Watt
    75 Watt 18 Watt
    100 Watt 23 Watt
