Light Emitting Diode (LED) lighting has been developed for horticulture since the late 1980s, yet it remains on the periphery of mainstream sources for glasshouse lighting. Conventional assimilation (supplementary) lights, such as high-pressure sodium (HPS) lamps, still tend to be the go-to option for many growers for various reasons. In this technical update, we consider the developments in LED technology in recent years and whether or not LEDs are an economically viable alternative to conventional light sources.
