Buy Unique UV Grow-Lights

Exploiting our patent portfolio, we research, develop, manufacture and sell UV lighting. The new UV420W grow-light focused at 280-550 nm, complements HPS and LEDs to deliver a broader solar spectrum and a superior growing environment. Historically overlooked, UV-B is vital. In their native habitats, crops utilise solar UV-B, but in greenhouses all UV-B is blocked by glass. In trials with industrial hemp, UV420s along with HPS boosted cannabinoid production by 40%. Choose this unique UV lamp and improve your crop quality and economics.

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.

Further Information

Future Applications

Delivering flexible spectral outputs, plasma lighting offers practical economic solutions in horticulture and other applications requiring natural solar levels of UV-A and UV-B, or UV-C for sterilisation.

Plasma Light Technology

Ceravision’s plasma grow-lights, with a spectrum providing UV-B, UV-A and blue herald a new scientific future in horticulture lighting and UV-B is beneficial for humans producing the vitamin D essential for health.
