In addition to switching from old-fashioned incandescents to energy-saving incandescents, CFLs or LEDs there are other ways you can save energy on lighting. Consider these energy-saving strategies and tips.
Shopping strategies
Choose ENERGY STAR®
ENERGY STAR qualified light fixtures meet high energy-efficiency standards, so you can be sure that they’re a good choice.
Choose the right light
While you don’t want areas too dim, you don’t want to over light spaces either because it wastes energy. Evaluate your lighting needs and choose bulbs with the right lumen output and other features important for your application.

Lock in energy efficiency with GU24 options
More and more energy-efficient lighting fixtures now feature GU24 sockets. GU24 compact fluorescent lights and LEDs have a pin base instead of a screw-in base. That means the fixture will always be energy efficient because it accepts only GU24 bulbs — never energy-wasting incandescent bulbs. Stores that sell GU24 fixtures offer GU24 lights, too. (Here’s a photograph of a GU24 CFL on the website for Rejuvenation, a lighting retailer.)
Choose the right bulbs for dimmers
If you have dimmer switches, and you want to replace old-fashioned incandescent light bulbs in those fixtures, opt for energy-saving halogen incandescents. Many LEDs can also be dimmed but you need to check that the one you want is compatible with your existing dimmer and that it was also designed to work with low-wattage loads. Some CFLs are labeled as dimmable, but the technology still has some drawbacks (limited dimmable range, among others).
T8 fluorescent lights are tops for your workroom, garage and laundry areas
The 4-foot-long tube T8 fixtures with electronic ballasts save energy and provide great light for working. You won’t have the hum and flicker of older T12 fixtures. Remember not to stick T8 lamps in your old T12 fixtures even though they will fit. You will need a new T8 fixture or else replace the existing T12 magnetic ballast with the proper T8 electronic ballast. It’s best to get an electrician to do this for you.

Low-cost projects
Install lighting controls
Occupancy sensors, timers and dimmers are all good ways to save. There are many different styles available at hardware and home stores. (Occupancy sensors and timers are generally not recommended for use with CFLs because they can shorten the lifespan of CFL bulbs.)
Choose motion detectors for outdoor lights
They help save energy and also offer a security advantage by surprising unwanted intruders. You can find outdoor fixtures with motion detectors built in. (Motion detectors are generally not recommended for use with CFLs because they can shorten the lifespan of CFL bulbs.)
Photo sensors turn lights on at dusk and off at dawn
If you like to leave your porch light on all night for safety, a photo sensor can save energy with the automatic shutoff — you’ll never forget to turn off the lights in the morning. (Photo sensors are not recommended for use with CFLs because they can shorten the lifespan of CFL bulbs.)

Easy, no-cost behaviors
Turn it off
Get in the habit of turning off lights whenever you leave a room. Teach this habit to your children, too — they’ll love reminding you! CFLs are an exception — turn them off if you’re leaving the room for more than 15 minutes, otherwise go ahead and leave them on if you are coming right back. Frequent switching shortens the life of CFLs.
Use task lighting to focus light right where you need it
For example, if you’re studying, a desk lamp is more efficient than lighting the whole room.
