Trancend’s bulbs differ from typical LED lights because they only use blue light. The company has developed a wavelength conversion system that uses phosphorous to convert blue photons, which are the most efficient type of photon, into any other color photon. Typical LEDs used for illumination are blue LEDs with a phosphor coating to produce white. Transcend is doing essentially the same thing, but the goal is to produce wavelengths optimal for plant growth instead of a broad spectrum for illumination. The biggest difference in implementation looks to be that Transcend is separating the phosphor from the emitter while most LEDs used for illumination bond the phosphor directly to the emitter.
