Plasma UV Grow-Lights for Horticulture

Ceravision's UV plasma grow-light provides the vital UV-B blocked by greenhouse glass and not provided by PAR grow-lights. For plant quality, UV-B is crucial: it stresses the plants to produce numerous nutritional and medicinal compounds vital for our health and well-being. During growth, our high output UV grow-light, with UV-B, UV-A and Blue light, boosts the valuable secondary metabolites in plants that produce essential oils, phenolics, terpenoids and antioxidants. The UV420 grow-light can also be used post-harvest to boost these compounds to prolong freshness and shelf-life; and between cycles it can help eliminate mould and bacteria. The world faces challenges in food security whilst dealing with scarcities of land, water and energy, along with climate change and globalisation. Ceravision’s HEP plasma lighting can help tackle these global issues.

ionCORE® Technology

Ceravision's plasma grow-lights offer flexibility in spectral output and with UV are perfect complementary horticulture grow-lights particularly for high value crops particularly for hemp and cannabis.


The UV420 plasma grow-light delivers the vital UV-B, UV-A and blue light 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.
