The BG Electrical Nexus Screwless Flat-Plate FBN84 is a black nickel quad (4 gang) two-way dimmer light switch, rated at 200W. Manufactured by British General Electrical, the FBN84 is a trailing edge dimmer switch suitable for domestic or commercial settings requiring variable light levels for LED, halogen, CFL, or incandescent lAs. With its sleek design featuring a thin plate, flat profile, rounded edges, and stylish black nickel finish, the FBN84 complements various interior decors. It offers smooth, noiseless dimming and is designed to prevent flickering with lower-wattage lAs. Equipped with BG's soft start technology, it extends lA lifespan by gradually bringing them to the desired light level. The switch also includes safety features such as overload protection and an integrated moisture-controlling gasket for installation in recently plastered walls. The FBN84 is backed by a 25-year guarantee and is compatible with trailing edge lAs and BG Luceco lAs. It features angled in-line Colour-coded captive terminals and is suitable for tungsten lAs, low voltage transformers, and mains GU10 halogen lAs. De-rating is required for optimal performance.
