Plasma UV Grow-Lights for Horticulture

Exploiting the flexibility and reliability of Ceravision’s patented plasma lighting, we have developed a unique horticulture UV grow-light. Its spectrum, concentrated in the 280-550nm range, provides the vital UV-B/UV-A blocked by greenhouse glass and unavailable from other grow-lights. Research is progressively proving that UV-B/UV-A is vital for maximising nutritional and medicinal crop values. The new UV420 unit complements PAR-lights to better replicate the solar spectrum. It will improve the economic and environmental efficiency of indoor cultivation. In trials on industrial hemp, its inclusion boosted cannabinoids by 40% and reduced powdery mildew and pests infestations.

ionCORE® Technology

By exploiting the dosing flexibility in the technology we have created a unique high UV-B/UV-A spectral output to complement PAR grow-lights in horticulture.


The UV420 plasma grow-light has the vital UV-B and UV-A blocked by greenhouse glass and missing from PAR grow-lights, to reduce costs, add value and increase yields.


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