Anyone in the business of SSL has either considered the fate of the CFL lamp, or used it as a whipping boy for marketing efforts. Why can’t this lamp catch a break? Is there anything we can learn from this product in deploying solid-state technology?

This is a residential lamp, rarely used in the commercial sector.

To truly put this in perspective, let’s separate reality from conventional wisdom.

First, the compact fluorescent lamp has been a huge success in the commercial market, where plug-in lamps are used with external electronic ballasts. These small lamps fill 90% of the decorative wall sconces, bowls, and surface ceiling luminaires, and over 50% of the recessed downlights in commercial, institutional, industrial, retail, and health care facilities around the country. The incandescent lamp was kicked to the curb for being an energy and maintenance resource consumer. Plug-in style CFL lamps range from 7 watts to 120 watts, in configurations that include twin tube, triple tube, and quad tube configurations. They are seen in 2,700k, 3,000k, 3,500k, and occasionally 4,100k. While there are many that are dimmed, most operate on simple switches or automatic controls. The hospitality market has adopted this lamp in new products, in combination with the screw-base retrofit lamp to eliminate incandescent table, downlight, accent and wall sconce lighting.

As an artist at heart, lighting is appealing, as it shapes the visual experience of observers as much as an oil painting hung over a couch. Lighting is both ethereal (it exists, yet is untouchable), and mechanical (requires hardware to manipulate and generate illumination). There is nothing else in the universe of human endeavor that blends art and science in this way. If this were all just about illumination of space to enable and excite human vision, there is enough meat here for anyone to enjoy a lifelong pursuit of it. But, this no longer the case. (more…)

There is a great deal of consternation about the entry of LEDs and solid-state lighting into the mainstream lighting market. There are four resonate weaknesses cited often. Just how do these stand up to scrutiny? Let’s find out: (more…)

In the late 19th century, a new and seemingly magical science emerged in the form of distributed electrical energy. At the same moment, the automobile and airplabe were also entering the market. As the Civil War played itself out, the world changed in profound ways, for every person on the planet. The transformation changed our lighting from fuels sources to electric light. Horses stayed in the pasture as owners rode in new cars. The population of cities exploded, and farms blew away in dust storms. In this same period of time we suffered the Great Depression. Heading into World War One, everything had changed, everywhere. (more…)
