Halogen, CFLs, LEDs, Watts, Lumens—what’s the difference? What’s best? We’ve got you covered! Lighting a typical Minnesota home accounts for about 10 percent of the energy needed to power one’s home. One of the best ways to reduce your electricity bill is to replace traditional incandescent light bulbs with ENERGY STAR labeled compact fluorescent light bulbs (CFLs) or light emitting diode bulbs (LEDs).
How can I save money on my lighting bill?

Halogen bulbs are one lighting option. They last about three times longer and use 10 percent less energy than a standard incandescent bulb with the same light output. But they rank well below CFLs and LEDs in efficiency and longevity. |

CFLs use about one-third of the energy and last up to 10 times longer than an incandescent bulb with the same light output. Also, CFLs have overcome many of the problems associated with their initial production in the 1990s. Newer CFLs have electronic ballasts which eliminate most of the flickering and slow starting of earlier models, and ENERGY STAR standards have improved reliability and expected lifetimes considerably. |

LEDs are the longest lasting bulbs on the market, lasting about 10 years and about three times longer than CFLs. They are roughly equivalent to CFLs in efficiency. Their longevity makes them a good choice for locations where bulb change-outs are either difficult or costly. Manufacturers are providing a growing selection of LEDs to meet specific lighting needs and compete with CFLs. |
Compare efficient bulbs in person at the State Fair!
At this year’s Eco Experience exhibit at the Minnesota State Fair you will find a wall of lighting in the Energy Home display that allows you to compare bulb type, brightness, and color to see which bulbs will be the best fit for you. CERTs staff and other lighting experts will be on hand to answer your questions.
