GE introduces LED bulb that replaces 100-watt incandescent

GE Lighting is introducing a new light-emitting diode replacement for the traditional 100-watt incandescent light bulb. The new LED packages 27 watts of input power in a standard “A-19” bulb shape. The GE Energy Smart(R) 27-watt LED bulb will be on store shelves the first half of 2013.

GE’s existing portfolio of LED bulbs includes a 13-watt LED (60-watt incandescent replacement) and a 9-watt LED (40-watt incandescent replacement), which was the first incandescent-shaped (A-19) LED in the world to earn ENERGY STAR® qualification.

The technical challenge was cooling a 100-watt A-19 shaped replacement LED bulb without making it ­physically bigger. Each subsystem such as optics, electronics and thermals needed to be designed for miniaturization and cooperative performance.

The new one tops the traditional bulb that hasn’t changed that much since Edison’s original bulb. The 27-watt LED bulb has 1,600+ lumens, uniform omnidirectional light ­distribution, 3000K color ­temperature, 25,000-hour life rating (22.8 years at 3 hours per day), dimmable, no ­mercury, instant full brightness and 60+ lumens per watt—all fitting neatly in the ­standard A-19 bulb shape.
