The original Black Light Cannon is a 400 watt (E40 Bulb) high pressure fixture ideal for permanent installations or Professional use in medium to large venues including Theatrical Stages, Concert Production, Night Clubs and Industrial venues. It offers powerful Ultraviolet light production using traditional technology. This fixture is heavy, almost 30lbs. It needs 5-10 minutes to warm up and gets HOT over time. You’ll need dedicated power as each fixture will draw 6 amps! We recommend mounting from a truss or ceiling beam where it cant be reached by party goers! At 365nm wavelength this fixture gives off very little “Blue Hue” often associated with Black Lights and is great for specialized use.
