New Selections: LED Light Bulbs

An LED lamp (LED light bulb) is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. LED lamps are used for both general and special-purpose lighting. Where colored light is needed, LEDs come in multiple colors, which are emitted with no need for filters. This improves the energy efficiency over a white light source that generates all colors of light then discards some of the visible energy in a filter. Many LED lamps have become available as replacements for screw-in incandescent or compact fluorescent light bulbs, ranging from low-power 5–40 watt incandescent bulbs, through conventional replacement bulbs for 60 watt incandescent bulbs.

Dimming CFLs and LEDs
Dimming saves energy while setting the right light level to improve mood and ambiance. Screw-in compact fluorescent lamps (CFLs) and screw-in light emitting diode bulbs (LEDs) are a great energy-saving alternative to incandescent or halogen light sources; however, dimming them may be difficult. Lutron’s new C•L™ Dimmers for dimmable CFL and LED bulbs have HED™ Technology which helps alleviate your CFL and LED dimming challenges.
Challenges of Dimming CFLs and LEDs with Standard Dimmers

Lutron CL Bulb typeEnergy-saving CFLs have been in the marketplace for many years but a broad range of dimmable bulbs has only recently become available. LEDs are even newer to the market and dimmable versions are also only recently available.

These dimmable bulbs, especially CFLs, have historically presented problems when used on standard incandescent dimmers.

Common issues include:

Reduced dimming range: Incandescent/halogen bulbs will typically dim lower than CFL or LED bulbs. Most dimmable CFLs will dim down to 10% to 30% measured light output. Early versions of dimmable LEDs on the market have the ability to dim lower than CFLs and can reach levels as low as 5% to 15% measured light. The actual dimming range is dictated by the bulb’s circuitry.

Lights dropping out: As CFL or LED bulbs are dimmed, they will sometimes turn off before the slider reaches the bottom. Referred to as “drop out,” this makes it extremely difficult to set the dimmer at the right level without bulbs turning off.

Lights not turning on: After being dimmed to a low light level and switched off, sometimes CFL or LED bulbs will not turn on until the dimmer’s slider is moved up. This is referred to as “pop-on,” which is especially challenging in 3-way situations where lights can be turned on/off from different locations, not just using the dimmer.

Lights turning off unexpectedly: Dimmable CFL and LED bulbs can be influenced by line voltage fluctuations. As your incandescent bulbs will sometimes dim or flicker when a device such as air-conditioning or a hair dryer is used, a dimmed CFL or LED can actually turn off or flicker excessively in those situations.

Note: Actual performance of any CFL or LED will vary from bulb type to bulb type and among different manufacturers. It is important to note that only bulbs that have been designed as dimmable should be used on a dimmer. To find out if your bulb is dimmable, please check the package, the bulb itself, or call the bulb manufacturer directly.

New Dimmers from Lutron
To help combat these issues, Lutron has developed a family of C·L dimmers for dimmable CFL and LED bulbs. By incorporating HED Technology, these dimmers improve the dimming performance of dimmable CFLs and LEDs compared to standard dimmers by:
  • Keeping the lights on as they are dimmed
  • Making sure the lights turn on at all light levels
  • Eliminating/reducing excessive flicker
  • Keeping the lights on even with line voltage fluctuations
About HED Technology: HED Technology features advanced dimming circuitry that is designed for compatibility with most high efficacy light bulbs.

Lutron C·L dimmers with HED Technology also provide full-range dimming for halogen and incandescent bulbs, ensuring today’s dimmer is compatible with tomorrow’s light sources. The dimmer can even dim a mixed load of light sources (i.e. LED and halogen or CFL and LED bulbs on the same circuit). C·L dimmers are available in our Diva®, Skylark Contour™, Luméa®, Ariadni®/Toggler® and Credenza® product families.
Adjustment Dial
Lutron CL adjustment DialYou may have noticed that your wall-mounted dimmer is equipped with an adjustment dial. Because performance is so varied from bulb to bulb or manufacturer to manufacturer, the adjustment dial will help you set the bottom of the dimming range for your particular bulbs.

Bulbs Approved for Use with this Dimmer
Per UL standard 1472, Lutron must test each bulb to ensure its compatibility with our C·L dimmers. For a list of compatible bulbs click on the link below. This list will be updated as Lutron tests more bulbs. Please check back regularly for updates.

DOE Report Compares Environmental Impacts of LEDs, Incandescent and CFL

The U.S. Department of Energy (DOE) has published a report that looks at the direct and indirect material and process inputs to fabricate, ship operate and dispose of LED lamps, compared with incandescent lamps and CFLs.
Among the key findings of the report, entitled LED Manufacturing and Performance are:
  • Electricity consumption over an equivalent period of lighting service is far greater for the incandescent lamp and is the dominant contributor to environmental impacts.
  • Because of its low efficacy, the incandescent lamp is the most environmentally harmful of the three lamp types considered, across all 15 impact measures.
  • The CFL is slightly more harmful than the 2012 LED lamp (today's LED technology) on all impact measures except hazardous waste landfill, where the LED lamp's large aluminum heat sink causes greater impact because of the energy and resources consumed in manufacturing it (which produces significant waste disposed of in landfills).
  • The best-performing light source is the LED lamp projected for 2017, whose prospective impacts are expected to be about 50 percent lower than the 2012 LED lamp and 70 percent lower than the CFL.
