Flowtron"s Galaxie Wall Sconces combine up to 40 watts of ultraviolet blacklight energy with an exclusive fly attracting pheromone to make it a powerful fly control unit that is ecologically safe, effective and economical to operate. Flies and other light sensitive flying insect pests are attracted to the unit"s ultraviolet light and special fly lure, and are eliminated as they come in contact with the large capacity strategically placed, no escape, replaceable adhesive board. Galaxie Wall Sconces provide for deflector panels to concentrate the UV radiation and to prevent the UV light from reflecting onto the mounting surface causing these surfaces to fade. Ideal for use in restaurants, food take-out locations, bars and lounges, supermarket meat and deli areas, food processing plants, hospitals, schools, offices or any place where flies are a threat to sanitation and where the use of chemical pesticides is undesirable. Flowtron"s Galaxie FC4400 Galaxie Wall Sconce is stylish and discreet with an unobtrusive, attractive design, in eye-appealing beige, and is ideally suited for installation in front-of-store locations or in any sensitive area where flies are a threat to sanitation and where the use of chemical pesticides is undesirable.
