XP-G LEDs are now delivering 140 lm/W, claims manufacturer Cree.
"Cree is providing commercially available 140 lm/W components," said the firm's marketing director Mike Watson.
The cool white colour version provides up to 148 lm (141 lm/W), then there is 139 lm (132 lm/W) from the 4,000K outdoor white, and 122 lm (116 lm/W) from the 3,000K warm white, all at 350mA.
XP-G is Cree's small form factor large (1.4x1.4mm) die surface mount lighting LED, competing with Lumileds' large die Rebel ES.
