High-power LEDs grow new markets in horticulture

January 25, 2017 // By Graham Prophet
LED maker Plessey (Plymouth, UK) has described an LED lighting application in which its high-power horticultural LED grow light directly replaces sodium lamps, and cuts energy by 40%

The Hyperion family of high-power horticultural LED grow lights has been designed to provide supplementary lighting in greenhouses (glasshouses). Hyperion 1000 and Hyperion 1600 units deliver greater returns for commercial growers through increased productivity while achieving a 40% energy saving compared to equivalent 600W and 1000W sodium grow lights.

 

Following on from the Attis range of grow lights, these initial Hyperion grow lights respectively deliver photon fluxes of 1000 µmol/sec* and 1600 µmol/sec, and are suited to growing vegetables, flowers, young plants and medical marijuana. They are directly equivalent to standard 600W and 1000W sodium grow lights. Hyperion units can be used to add to or replace existing installations. Plessey’s Hyperion grow lights provide a variety of spectrums to enhance yield, quality and consistency by controlling the speed of plant growth, flowering and fruiting – possibly extending crop production and product shelf life.

 

[* units are micro-mole/sec, where mole has the numerical value familiar from chemistry, ~6x10 23, thus 1 µmol is ~6x10 17 photons.]

The 1:1 equivalence between Hyperion 1000 and Hyperion 1600 grow lights and the 600W and 1000W sodium lights that growers, greenhouse builders and installers have been using for many years, offers numerous benefits in evaluating, installing and using LED lighting. Comparisons between LED and sodium grow lights have previously been difficult because of the need to use more LED lights to match the light output of sodium lamps. For a given installation, the same number of Hyperion units can be used to directly replace sodium units, which would be far fewer than any competitive LED solution. Hyperion permits greater lighting design flexibility with more even light distribution and less shading than alternative lower-power LED fixtures.
