General Information (FAQ)
What is ENERGY STAR®?ENERGY STAR is a government program sponsored by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). ENERGY STAR helps consumers identify energy-efficient products. Look for the ENERGY STAR designation when purchasing bulbs, appliances, home electronics and heating and cooling equipment.
Why choose ENERGY STAR certified bulbs?
What is an LED?LEDs are small light sources that become illuminated by the movement of electrons through a semiconductor material. Many LED products are now found on store shelves. For the highest quality, buy bulbs with the ENERGY STAR logo.
Buying ENERGY STAR Bulbs
Will ENERGY STAR-certified bulbs fit into my existing fixtures?ENERGY STAR bulbs can replace standard incandescent, CFL and haolgen bulbs in almost any fixture. Specialty bulbs include globe lamps for your bathroom vanity and chandelier bulbs or lamps for recessed downlights. Check the packaging of the bulb to ensure it’s meant for your intended purpose.
Can I use ENERGY STAR bulbs with outdoor fixtures?Certain bulbs are appropriate for outdoor use. Bulb packaging provides information on temperature ratings and outdoor uses.
What is the warranty on ENERGY STAR certified bulbs?All ENERGY STAR certified bulbs come with a warranty. Refer to the bulb packaging for details. Warranties range from two to three years for residential use. Keep your receipt in case your bulb does not last as long as advertised.
Can I really save as much as the package says by installing an ENERGY STAR-certified bulb?While you will save energy by using an ENERGY STAR light bulb over an incandescent, read the packaging carefully to determine how the advertised savings were calculated. Rates, timeframes and number of bulbs used to calculate the savings can vary. Most manufacturers use an electric rate based on a national average. Keep in mind that Idaho Power’s residential rate is generally lower than the national average. Calculations on a multi-pack may group the savings into one larger number that adds the savings from all the bulbs. Additionally, savings may be reported as yearly savings or over the life of the bulb.
What is a watt?A watt measures how much energy a bulb uses. Although we associate higher wattage bulbs with greater light output, watts are not technically a measure of brightness. However, for replacing incandescent bulbs, watt equivalents can help narrow the search for the right bulb. The packaging for most ENERGY STAR bulbs provides the wattage of the bulb and the incandescent equivalent.
What is a lumen?A lumen is the measurement of light output. The higher the lumens, the brighter the bulb. Two bulbs that use 15 watts can range in brightness. A 13-watt bulb with a brightness of 800 lumens puts out more light for the same energy as a 13-watt bulb with a brightness of 750 lumens.
Why are bulbs labeled with different terms like soft white, bright white and daylight?There are many shades of white light measured in degrees of Kelvin (K). Warm colors work well in area lighting or mood lighting and have lower Kelvin temperatures. Use cooler lights with a higher Kelvin temperature, such as “daylight” or “bright white” for a bluer color. Cool colors work well for tasks like reading.

Using ENERGY STAR Bulbs
Can ENERGY STAR certified bulbs be used with a dimmer switch?Yes. Only certain bulbs are made to work on dimmers. The packaging information identifies whether the bulb is for use in a dimmable fixture. Dimming a bulb not designed to work with a dimmer switch may shorten its life or impact its performance.
Is it true that CFL bulbs contain mercury?CFLs contain a small amount of mercury sealed within the glass tubing, an average of 5 milligrams. By comparison, the average home thermometer contains 500 milligrams of mercury.
What should I do with a CFL when it burns out?Fluorescent light bulbs, including CFLs, contain a small amount of mercury. Idaho Power encourages safe handling and proper disposal of fluorescent bulbs. Please contact your local landfill or solid waste collection company for information on household hazardous waste collection programs or special handling requirements. Learn more at http://epa.gov/cfl/.
My bulb burned out early. Why?While it is hard to know exactly why a bulb may fail, some items to consider include:
- Was it an ENERGY STAR bulb? Bulbs must meet stricter quality control guidelines to receive the ENERGY STAR designation. If the bulb was an ENERGY STAR bulb, report the failure through www.energystar.gov.
- Was it the right bulb for the application? Bulbs used with dimmer switches, three-way switches, motion sensors or outdoors must be rated for that use.
- Was the bulb placed in an enclosed fixture? Before using a bulb in an enclosed fixture, consult the product packaging. Bulbs not designed for totally enclosed fixtures will typically carry a disclaimer indicating they are not intended for this type of application. Because enclosed fixtures do not allow air to circulate around the lamp, heat builds up, which can lead to performance issues.
