Florida-based lighting company ClearLite is introducing a new CFL bulb with an unbreakable safety shell that prevents mercury from escaping, a feature that addresses some health concerns with CFLs.
The SX-4000 silicone skin remains intact even if the ArmorLite bulb inside shatters, according to ClearLite, which is rolling out its bulb in December and January.
Not everyone is aware of the danger of broken CFLs. Because of the small amount of mercury in them, current EPA guidelines call for evacuating people and pets from the area where a bulb has shattered.

They also call for the room to be aired out for 15 minutes and the air conditioning to be shut off.
The 9-watt (40-watt equivalent) and 14-watt (60-watt equivalent) ArmorLite bulbs look somewhat like incandescents and can be used for 10,000 hours, according to ClearLite. They contain amalgam, an alloy of mercury, in solid form.
CFLs can usually be recycled at retailers or municipal hazardous waste programs, though the silicone skin in ArmorLite bulbs will require extra steps or a special program to process.
The 800-lumen bulbs are Energy Star-rated and will be available in "natural soft white" and "natural brite white" varieties, with a suggested retail price of $7.99.
The silicone skin may have some effect on the perceived color of the light. There's limited color temperature information on this page, and a bit more information about ClearLite bulbs in this video.
ClearLite plans to produce other varieties of ArmorLite bulbs such as a bathroom-use vanity globe. Samples of the A-shape bulb are already available.
High price and a strange color. No, we're not talking about a hairdo. Those are the two factors that have kept light-emitting diodes, or LEDs, from becoming a mainstream light source.
But that might change soon, said Zach Gibler, chief business development officer of Lighting Science Group, which plans to announce distribution deals with major retailers for its LED bulbs that screw into a regular socket.

Lighting Science Group this week plans to introduce a portfolio of LED replacement white lightbulbs that it hopes will attract more consumer interest. The product line uses the same sockets as Edison bulbs.
According to Gibler, the bulbs perform well on a warmth and color rendering index--blue looks blue, yellow looks yellow, etc.--they have a long life cycle, and consume 80 percent less energy than incandescent bulbs.
Gibler believes 2008 could be "the year of LED" for residential use and lighting in general. The market potential is big, particularly considering that legislation will outlaw the sale of incandescent bulbs by 2012, he said. He compared the adoption of LED lights in homes to another lighting product, the flashlight.
"Three years ago you could hardly find an LED-based flashlight; today it's hard to find one that is not LED light," he said.
Lighting Science Group sells its products through wholesale stores and on its own Web site, but it expects to announce soon distribution deals with one or two retail chains to make the new LED bulbs more available.

At $40 to $110 apiece, the LED "in-screw" bulbs may still seem too pricey for a lot of consumers. But Lighting Science Group's pitch is that a 50 cent Edison bulb will last for 750 to 3,000 hours, while an LED has to be replaced only every 50,000 hours (or 10 to 30 years). The company says the cost savings is almost $740 over a lifetime due to much lower energy consumption.
Vrinda Bhandarkar, a research analyst at Mountain View, Calif.-based Strategies Unlimited, said she is impressed if the "bulky looking lamps" actually perform as well as the company says. But the price has to come down a lot before consumers--and not just businesses--start buying them, she said. For a proper light in the kitchen it would take at least four big bulbs, which would cost about $440.
"They will be used for retail display, hotel lobbies, for paintings that hang up high, and places where you need a high ladder to change lamps," she said.
Gibler, who has a lengthy career in the lighting industry and took on responsibility for business development at Lighting Science Group last year, believes the price for LED lights will come down as chips get cheaper.
"They will be half the cost in another two years," he said.
