LEDs are no longer just for lighting. In recent years, LED technology has spread into the horticultural industry. Differing from traditional incandescent bulbs, LEDs are able to be designed to mimic sunlight and give off wavelengths necessary for plant growth. This allows for larger yield and year round harvesting. The past few years has seen a growing trend in horticultural lighting, which was evident at this year’s Taiwan International Lighting Show (TILS) 2014.
