The companies say the 4Watt replacement lamp provides a superior ratio of lumens per watt, cutting total cost of energy by 90 percent compared to a standard 40W bulb. It fits current bases and fixtures for incandescent and compact fluorescent lamps.
The lamp is manufactured by LEDs America and sold by Viper Networks under the brand name LED-O.
Federal regulations require bulbs that emit light equal to that of a traditional 100-watt bulb to draw only 72 watts of power, starting in October, with standards for lower-wattage bulbs phasing in over the next two years. By January 1, 2014, bulbs with light output equivalent to a traditional 40-watt bulb will have to draw 29 watts or less.
Meanwhile, California has placed itself one year ahead of the federal schedule, with its rule on 40-watt bulbs kicking in on January 1, 2013.
Last year Philips unveiled what it says is the world’s first LED replacement for the 75-watt light bulb. The Philips EnduraLED A21 is a 17-watt model that cuts energy consumption by 80 percent compared to a traditional 75-watt bulb, and lasts 25 times longer.
Around the same time, Switch Lighting announced what it calls the first LED light equivalent to a 100-watt incandescent. The A19 lamp produces 1700 lumens in neutral white, the same color as halogen track lighting.
