A Better Bulb
While not all bulbs and dimmers are compatible, PowerKeep 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 PowerKeep 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. PowerKeep 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.
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 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.
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 (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.
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.
