Light emitting diodes represent a promising technology for the greenhouse industry that has technical advantages over traditional lighting sources, but are only recently being tested for horticultural applications(Mitchell et al 2012). Light emitting diode(LED) is a unique type of semiconductor diode. The wavelength of the light emitted(the color of light) depend on the properties of semiconductor material. LEDs can have peak emission wavelengths from UV-C 250 nm) to infrared 1000 nm) (Bourget 2008) and first light source to have the capability of true spectral control, allowing wavelengths to be matched to plantphotoreceptors to provide more optimal production and to influence plant morphology and composition(Morrow 2008). The fast technological progress of LEDs due to their extensive usage for other industrial applications provides various advancements for horticultural lighting.
