This GE Bulb was tested by green living guy staff and for an indoor lamp it passed the tests.
GE Lighting has illuminated a light-emitting diode replacement for the 100-watt incandescent light bulb—developed in its East Cleveland, Ohio LED lab—that packages 27-watts of input power in a standard “A-19” bulb shape.
The GE Energy Smart® 27-watt LED bulb incorporates proprietary synthetic jet technology that was enabled by GE’s collaboration with ecomaginationSM Challenge winner Nuventix, creator of LED cooling technologies for energy-efficient lighting.
GE’s 27-watt Energy Smart® LED bulb, on store shelves in the U.S. and Canada adds to the 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.
“Our innovation team has tackled a previously insurmountable technical challenge: cooling a100-watt A-19 shaped replacement LED bulb without making it physically bigger,” says Steve Briggs, general manager of LED systems, GE Lighting. “Each subsystem such as optics, electronics and thermals needed to be designed for miniaturization and cooperative performance. We explored the limits of what’s possible and pushed far beyond industry expectations and competitors’ thinking and product offerings.”
GE testing stated and green living guy staff confirmed the 100-watt incandescent replacement metrics: 1,600+ lumens, uniform omni-directional 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.
