And the efficiency is based on what?LEDs from Steveleds.com aren't that efficient. Bought them myself and measured.
deep red: Vf 2.73@700mA about 34% efficient @50 degC
royal blue: Vf 2.83@700mA about 50% eff @50 degC
Assuming that output, which i can't measure, is correct.
Best royal blues are Cree XT-E. More efficient than Rebels while binned @85 degC.
