Expert's Opinion on the Cree's TrueWhite® Technology Based Lamp Prototype

Aug 4, 2011 According to the recent interview  with Lux Research analyst Murray McCutcheon published by VentureBeat, despite the outstanding characteristics of the new Cree prototype lamp based on TrueWhite® Technology it may not be enough to tackle the industry and/or general consumer market  since the production costs are still too high.

Recently revealed Cree prototype LED bulb produces 152 lumens per watt , while a typical incandescent bulb only generates around 14.6 lumens per watt. The new bulb, producing around 1,300 lumens using Cree’s new “TrueWhite” technology, exceeds the performance goals set by the U.S. Department of Energy’s L Prize competition. Yet, by McCutcheson;s estimation LED lighting cost around $18 per kilolumen produced, while incandescent bulbs can be made for only around $2.20 per kilolumen. LED lighting bulbs probably won’t reach that point until 2015, he said.

“LEDs will gain their first traction in the government and some commercial buildings, because of the longer return on investment and payback horizons,” McCutcheon said. “However we see no in-roads into the residential market until 2020 because the payback period residential consumers demand is 2 years.”

The expert believes that LED lighting providers like Cree should capture around 30 percent of the commercial lighting market by 2015. However the regular consumer markets will only feel significant presence of LED Lighting around 2020, when it will have an opportunity to capture around 40 percent of the market, McCutcheon said.
