When we first reported on General Electric’s 9-watt LED in early April, details were somewhat scant. We knew the bulb could last up to 17 years when used approximately four hours a day, and we knew it was designed to emit light from all directions; we just didn’t know how, exactly, the design allowed it to do so. Newly released information from GE shines light on these and other details.
Resembling a crystal ball clasped in the claw-like head of a sorcerer’s staff, the GE LED lightbulb is expected to receive Energy Star certification as an omni-directional LED replacement bulb, which means light will be distributed in all directions from the bulb except for the narrow angles near its base. The bulb’s fins, while certainly distinguishing it from comparable LEDs, serve a higher purpose. “They’re connected to the LEDs inside the bulb to draw heat out, keeping the LEDs cool to ensure a longer life and greater efficiency,” explains GE. “The fins also keep the surface of the bulb cooler than comparable incandescent bulbs.”
Considered a replacement for 40-watt bulbs when it hits store shelves in August 2010, the GE LED bulb produces 450 lumens for a total of 77 percent in energy savings. Unfortunately, the price, as originally reported, still looks to be in the $40 to $50 range. Still, 50 bucks for 25,000 hours of light only seems pricey when you consider the initial cost.
