Plasma UV Grow-Lights for Horticulture

Exploiting our patented portfolio, we research, develop and manufacture UV lights. Our new UV420W grow-light for horticulture is an example. The UV420’s spectrum, focused in the 280-550 nm range, complements HPS and LED PAR-lights to provide a broader solar spectrum. Often overlooked, UV-B energises plants to maximise their genetic potential. Crops utilise solar UV-B in their native habitats but in greenhouses all solar UV-B is blocked by glass. In trials with industrial hemp, cannabinoid production was boosted by 40%.

ionCORE® Technology

By exploiting the dosing flexibility in the technology we have created a unique high UV-B/UV-A spectral output that complements PAR grow-lights in horticulture to better replicate solar radiation within a greenhouse or indoor growing environment.


The UV420 plasma grow-light delivers the vital UV-B, blocked by greenhouse glass and missing from PAR grow-lights. This grow light will boost quality, value and yields and help to deter pests and diseases to reduce the need for hazardous insecticides and pesticides and help cultivate a more organic regime with less residual chemicals.


The Environment is at the heart of all we do. We aim to ensure components and processes minimise environmental impacts as we develop plasma lighting to help address the global issues of food security, water supply and energy efficiency.
