Lighting Facts

Choosing the right light bulb

Wondering what compact fluorescent or LED light bulbs to buy to replace your old incandescent light bulbs? The chart below will help you while shopping. While LED bulbs are the most expensive, they also last the longest (about 50 times as long as an incandescent), are dimmable, and are not sensitive to temperatures and humidity. They also turn on instantly (unlike some compact fluorescents), and come in a variety of shapes, sizes and lighting coolness/warmth.

Making bulb upgrades affordable

While it can be expensive to proactively replace all of your light bulbs with energy-efficient CFLs or LEDs, a more affordable approach is to simply replace them as your old incandescent bulbs burn out. All light bulbs manufactured in 2012 or later will feature a Lighting Facts label. This information will help you decide which bulb, in regards to brightness, life expectancy, and light appearance, is right for you.

To help make your conversion to energy-efficient light bulbs even more affordable, you may qualify for a rebate on qualifying CFLs and LED light bulbs.
