The patented Free Dimming(TM) technology enables LED bulbs to dim using any on/off switch, thus eliminating the burden of installing expensive dimmers. It can work with any on/off switch, including wall toggles, paddle switches, pull cords, rotary switches and other types of on/off switches commonly found on walls, extension cords and table/desk lamps.
Industry has estimated that there are roughly 150 million incandescent dimmers installed in the USA alone. In theory, LED bulbs are fully dimmable; however, designing them to be compatible with incandescent dimmers is exceptionally challenging. Such designs add significant complexity and cost to the LED bulb, reduce efficiency, and often result in poor performance that leads to product returns and potential safety issues.
Chronic compatibility and performance issues include aesthetic problems such as flicker, audible hum, "jumpy" dimming, and poor turn-off performance. Others are various electrical issues such as inrush current, which stresses components in both the dimmer and LED bulb, shortening product lifetime and creating safety issues.
Furthermore, support for legacy incandescent dimmers does not address the more than 85% of light bulbs that operate from non-dimming on/off switches. Although there are 150 million incandescent dimmers installed in the USA alone, according to the National Electrical Manufacturers Association (NEMA), there are over 4.4 billion medium, screw-based light sockets in the U.S., representing an enormous, untapped market opportunity.
