Maes Lighting specializes in explosion proof lighting that is used for commercial Paint Booth Applications. The IR4- Class 1 Division 1 T8 or T5 is used for inside paint booths to give maximum protection. These lights are supplied with mounting brackets and 850K lamps included in the price. We have several different versions to choose from: IR4- 2 lamp, IR4 – 4 lamp in T5 and T8. We also have these in LED versions. We have a new version that is the only one on the market that we are aware of. It is a 2 tube 4 lamp – class 1 division 1 4ft. fixture. This gives the same amount of light output at the 4 lamp 4 tube light but at about half the price. Please let us help you with your lighting layout and supply needs.
