Application: AQUA- II are industrial dustproof and waterproof fluorescent lighting fixtures, designed for premises demanding resistance against dust penetration, splashing water and partial immersion. They can be used in vehicle washes, dams of water reservoirs, swimming pools and chemical industry. Body: Luminaire is formed by plastic tube with outer perimeter 70mm and 4 mm thick walls which is made from transparent polycarbonate. The tube guarantees good mechanical resistance against impact. The flammability level of the material is B (difficult of flammability). The tube can be produced from borosilicate glass or diffusive polymethylmethacrylate. The tube is ended off by sealing plug with bushing M20 (IP67). Reflector: The reflector of the lighting fixture is shifted in the basic body. The reflector is produced from aluminium profile. The electric components are mounted on it. Special profile is used for cover of electrical parts. Electric equipment: Luminaires are equipped with inductive or electronic ballast, three-pole (respectively five-pole) connector terminal block and lamp-holder of tubes G5 or G13. System of fastening: The lighting fixture can be fastened on the ceiling, respectively on the walls of illuminated space by means of special mounting brackets via four screws. Luminaire can be suspended on a cable by means of self-locking cable suspender or hung on a chain via suspension brackets.
