Philips Lighting North America has won the first award under the Department of Energy’s L-Prize competition. Philips submitted its entry in 2009 and the DOE has been field testing the bulbs for the past 18 months. The bulbs had to meet or exceed these requirements: greater than 900lm at 10W or less for an efficacy of greater than 90W/lm at a color-corrected temperature (CCT) of 2700-3000K and a color rendering index (CRI) of at least 90. The Philips bulb exceeded all these requirements during the 18 month trial.
In the announcement of the award, no mention was made of pricing; However, the original requirements called for a target retail price of $22 for the first year it was offered for sale, $15 for the second year, and $8 in the third year. Philips has said it plans to offer the bulb for retail sale as soon as early 2012.
Philips will receive a $10 million cash prize as well as L Prize partner promotions and incentives. To date, 31 utilities and energy efficiency program partners stand ready to promote and develop markets for the winning product. Up to two additional entrants in this category may be eligible for program partner promotions – in effect increasing the number of possible qualifying products to three.
The bulb uses a clever remote phosphor system to gain a spherical distribution of light, unlike earlier sno-cone LED bulbs. For a tear-down of a similar Philips bulb, visit:
