Dimming LEDs and CFLs Made Easy

Because of the ongoing incandescent light bulb phase out, people are seeking new, more energy-efficient sources. Screw-in Light Emitting Diode (LED) bulbs and Compact Fluorescent Lamps (CFL) are great, energy-saving alternatives. LEDs and CFLs can be effectively dimmed, but there are some challenges.

Dimming these bulbs saves even more energy and gives you the same kind of flexibility and control you expect from your incandescent bulbs. The bulbs will deliver excellent dimming performance when paired with a compatible dimmer.

Legislation Need to Know? What’s Next?

Legislation – What is the “Light Bulb Law?”

The Energy Independence and Security Act of 2007 (sometimes called the “lightbulb law”) set a new, energy efficient standard for light bulbs. Under this law,most incandescent bulbs can no longer be manufactured. New screw-based light bulbswill use fewer watts, and use less energy, to achieve the same level of light. Commonhousehold light bulbs that traditionally used between 40 and 100 watts will nowuse at least 27% less energy. The law took a phased approach, starting in January2012, and was completely implemented by January 2014.

What Do I Need to Know?
