I reverted your change to Luminous efficacy. The Cree diodes you linked to produce a total luminous flux of 107 lm. They do not have an efficacy of 107 lm/W. The page doesn't give an efficacy explicitly, but given the numbers in their datasheet it appears to be about 92 lm/W. (The 107 lm of flux is produced at a current of 350 mA and a forward voltage of typically around 3.3 V) The forward voltage can be up to 3.9 V, however, which would mean the lamp would consume 1.37 W of power to produce 107 lm, for an efficacy of just 78 lm/W.--Srleffler (talk) 03:41, 24 July 2008 (UTC)
