Red LEDs may have not joined the ranks of regular use like blue and white LEDs but that hasn’t stopped Sunbrite LED from bringing out a second crimson. In addition to their previous shade of red with a peak of 640nm, Sunbrite is here at RAP showing off their new “Far Red” LEDs with an emission peak of 680nm. You might think that a red is jsut a red but the color difference between the 640 red and the 680 far red is easily discernible to the naked eye. The Far Red LED from Sunbrite excites a different part of the photosynthetically active spectrum but it won’t excite your wallet any more than previous LED colors. The 15 Far Red LED watt spots will be $119 and the striplight t00b form factors for the same basic price as [previous Sunbrite lights.
