September 8, 2010... Nichia reports having achieved some impressive results in the lab for its white LEDs. In the latest issue of Physics D, Yukio Narukawa and a group of researchers from Nichia Corporation and Nitride Semiconductor Research Laboratory, claimed to have achieved 135 lm/W efficacy at 1A with four high power blue LEDs dies made into a white LED. Narukawa says that as far as he knows 135 lm/W is a record for 1A for a white LED.

The researchers reported that this white LED had a higher flux than a 20 W-class fluorescent lamp with 1.5 times the luminous efficacy of a tri-phosphor fluorescent lamp (90 lm/W). The researchers concluded that therefore, "White LEDs can soon be used in automobile headlights, large screen LCD backlighting and general home lighting."
