Cautions and Warnings: Not intended for use with emergency exit fixtures or emergency lighting. Light may not be compatible with all dimmers. For more information on dimmer compatibility please see below. Risk of electric shock or burns. Turn off power and let cool before inspection or replacement. Do NOT open, no serviceable parts inside. Use only on 120 volt AC circuits. Do not use if product is cracked or broken, even if light continues to operate. Suitable for use in operating environments between -4°F and +113°F (-20°C and +45°C). Suitable for use in damp locations, but not for use where directly exposed to weather or water. Do not use in totally enclosed fixtures. This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Visit for more information. RISK OF ELECTRIC SHOCK: do not use if the outer lamp envelope is damaged or broken.

While not all bulbs and dimmers are compatible, Energizer dimmable bulbs work with all major dimmer switches (download the compatibility chart), dim from 100 percent down to 10 percent without changing temperature and have an advanced driver to prevent flickering.

How to know if your dimmer switch is compatible with Energizer LEDs?
Here we’ve compiled a list of switches that we know are compatible with our bulbs, but there may be others. If you discover one that works, let us know.

Why do some dimmable LEDs flicker?
Flicker is caused by alternating current electricity passing through LED circuitry not appropriately designed to convert that current into steady light. This can be particularly noticeable when dimmed since the dimmer slows the alternating current waves to lessen the light output. Always make sure you select LEDs marked as ‘DIMMABLE’ when selecting bulbs to use with dimming switches.

What other features should you look at when selecting a dimmable LED?
Two often-overlooked issues with dimmable LEDs are color temperature changes when reducing the light output or limits to how much a light bulb can dim. Energizer LEDs are designed to reduce their light output down to 10 percent without flicker or changes to the light temperature.

The Lighting Facts label’s objective is to provide consumers with simple information when selecting the most appropriate energy-efficient bulb.

To cut through the confusion, we’ve developed this guide to help you understand the most common terms used in lighting along with specifications and certifications.

brightness iconBrightness

A light bulb’s wattage is no longer used to determine it’s brightness. Instead, a bulb’s brightness is rated in lumens. The more lumens there are, the brighter the bulb.

estimated yearly cost iconEstimated Yearly Energy Cost

This is the cost to light your bulb based on 3 hours a day and 11 cents per kilowatt hour (kWh). With LEDs, costs are a fraction of traditional incandescent bulbs.

life iconLife

LEDs list their lifespan on the label in years but they typically do not burn out. Instead, the light-emitting diode fades over time and is considered useful until it’s decreased by 30 percent. The useful life is what you’ll see on the label.

light appearance iconLight Appearance (Light Color)

Light color is measured on a temperature scale represented in Kelvin (K). The “warmer” the light, the lower the color temperature. arm, yellow-colored lights commonly used in rooms such as living room and home offices have a color
temperature of 2700 K. Cooler, blue-white lights used in bathrooms and kitchens are at5000 K and up.

energy used iconEnergy Used

A light bulb’s wattage indicates the energy the bulb uses. Energy-efficient light bulbs like LEDs list their ‘watt equivalent’ to communicate how bright the bulb is compared to an incandescent of much higher wattage. So, a 60-watt equivalent LED light bulb may only use 10 watts and but be just as bright as a 60-watt incandescent.
