Lighting Sciences Group 60-watt equivalent

The design of this Lighting Sciences Group bulb shows how manufacturers are trying to make the light more even, thus making LEDs better suited for a wider range of uses, such as desk lamps and overhead fixtures. LSG has released a 40-watt equivalent already and is expected to release a 60-watt equivalent by the end of the second quarter. It will have a color rendering index of 88, give off 850 lumens, have a color temperature of 3,000 Kelvin, and consume 13 watts. It will cost $34.97. A cooler light version at 4,900K will give off 950 lumens, consume 13 watts, and cost $36.97. The look will be similar to that of the bulb pictured here, a 40-watt equivalent, available now for less than $20.
