We have a brand new C1D1 Explosion Proof Light here at LED in Action! It is the perfect light for locations that are made hazardous by the presence of flammable vapours, gases or combustible dusts. It is ideal for retrofitting an existing HPS / MH light and offers higher efficiency for increased energy savings, power maintenance costs and shorter paybacks. It has a efficiency of 130 LM / W, is shock and vibration resistant with thermal shock and impact resistant glass lens, and has instant illumination so there is no warm-up time required.
