Bright Prospects for CFL TorchieresIt seems that everywhere we look these days--homes, apartments, dormitories, offices--people are using halogen torchieres to light up their lives. And what's not to like? The fixtures sell for less than $20; provide a tremendous splash of high-quality indirect light; can be dimmed to create whatever mood we desire; and are available everywhere in a variety of styles, shapes, and colors. Plus it says right on the box what we in the business have always believed: Halogen lighting--energy efficient.
Unfortunately, America's 40 million-plus halogen torchieres are lighting up more than our lives. They're also lighting up our energy bills and various combustible materials around the home. At 300W-600W apiece, each halogen torchiere can easily account for $35-$75 worth of electricity bills each year. Nationwide, halogen torchiere energy use may be as high as 16 billion kWh.
Fortunately, energy-efficient, safe alternatives are beginning to reach the marketplace. In autumn 1996, Energy Federation Incorporated received its first delivery of 200 fluorescent torchiere prototypes. Already earmarked for buildings at Harvard University and customers of Madison Gas & Electric, these Chinese-made torchieres utilize three quad lamps and ballasts to provide more light than a 300W halogen, using less than 100 W.
At the same time, Alsy Lighting and General Electric have launched a partnership to build torchieres based on GE's 2D lamp. A 38W 2D fixture utilizing a three-way switchable ballast was exhibited to lighting buyers at the High Point Furnishings show in October 1996. As of press time, a second product was to be introduced at year's end, which will use GE's new 55W 2D lamp to exceed the light output of a 300W torchiere. That product will likely offer three-way switching or dimming, which could be important to customers who enjoy the flexibility of traditional torchieres.
The efficient fixtures currently cost $40-$70, depending on configuration, manufacturer, and sales channel. This is higher than the $10-$30 price of halogen torchieres, but energy savings alone should make the efficient lights pay back in under a year. Extended lamp life is an extra selling point--2D and quad lamps are rated at 10,000 to 12,000 hours apiece, with ballasts lasting three to four lamp lives.
The alternative products may figure prominently in the upcoming roll-out of the U.S. Environmental Protection Agency's (EPA) Energy Star program for residential light fixtures. (Energy Star is a joint program managed by EPA and the U.S. Department of Energy to recognize voluntary efforts by manufacturers to improve the efficiency of their products.) Torchiere manufacturers are already scrambling to meet a February 1997 deadline from Underwriters Laboratories to make their products safer. Switching to a fluorescent light source could allow torchieres to easily meet that requirement, while also earning the Energy Star label. The label would give consumers a crystal-clear distinction between today's 300W ceiling heaters and the energy-efficient alternatives. Universities, with many halogen torchieres in their dormitories, are expected to be enthusiastic early buyers.
