Cree has introduced warm white and neutral white
versions of its XP-G lighting LED. In warm (3000K) white, they provides up to
114 lm and 109 lm/W at 350mA. At 1.0 A, output climbs to 285 lm and efficacy
drops to 84 lm/W "which is four times the light output than the highest
available XR-E warm-white LED at equal efficacy," said Cree.
The neutral (4000K) white version delivers up to 139
lm and 132 lm/W at 350mA, and up to 463 lm at 1.5 A "These LEDs can enable
LED lighting products that exceed the current ENERGY STAR luminaire and lamp
requirements," said Paul Thieken, Cree director of marketing.
Neutral-white and warm-white XP-G LEDs are
commercially available now.
