Based in Milton Keynes, Ceravision Limited is a private UK company, which is leading the world in the development of High Efficiency Plasma (HEP) lighting technology.  HEP lighting is based on microwave-powered electrodeless discharges and this enables the use of a large range of light emitters unavailable to conventional discharge lighting systems. 

The technology lends itself particularly to high-output applications including ultra-violet (UV) for water sterilisation and lighting for horticulture.   The flexibility inherent in the technology platform offers a comprehensive range of components that can be configured to particular market sector requirements.

In horticulture, HEP’s flexibility in providing tailored spectral distributions, long life and high efficiency is persuasive.  A light-source based upon these features has been developed within a unique lightweight luminaire for horticulture grow-lighting. 

This new grow-light with ‘blue-light’, UV-A and UV-B, demonstrates benefits over other lighting technologies.  It is attracting considerable interest from commercial growers and researchers worldwide.
