The IrradiatorTM is completely sealed with a double glass gasket for an air-tight seal. The swing stop retention cable reduces the risk of damage to the glass, captured thumb screws & the enclosure mechanism allow ease of use and ensure a tight seal. Manufactured from the highest quality materials with a powder coated galvanized steel housing, EZ Breeze aerodynamic junction box plus a highly reflective aluminium interior ensures this reflector provides excellent reflectivity and diffusion of light. The Irradiator’s design has been developed to incorporate beaded rings on the aircooling flanges to keep ducting securely in place. The Irradiator gives amazingly even light-spread in a 1.2m square grow-tent. The outer casing is manufactured from steel and powder coated to preserve its integrity and the construction is second to none. There simply isn’t a better air-cooled in this price range.
