OSRAM DULUX® F | 18W 4000K | 2G10 4-Pin Flat Compact Fluorescent Lamp

The OSRAM Dulux F 18W/840 is an ultra-low-profile compact fluorescent lamp (CFL) designed for shallow area lighting fixtures. Delivering 1100 lumens with a crisp 4000K Cool White color temperature, this flat-profile lamp is only half as long as a comparable Dulux L lamp, making it the perfect solution for modular 200mm and 300mm luminaires. Featuring a 2G10 4-pin base, it offers high luminous efficacy and a 10,000-hour rated life. Its compact design is ideal for recessed ceiling lights, downlights, and shallow wall fixtures in offices, hotels, and public buildings, providing excellent uniform illumination while reducing system costs.

Exceptional Efficacy in a Compact Form

The Dulux F series is characterized by its ability to provide high lumen levels within extremely shallow fixtures. Its 4-tube flat configuration allows for a more uniform light distribution compared to traditional circular or linear lamps in square fixtures. Whether operated on conventional or electronic control gear (ECG), this lamp simplifies luminaire handling and significantly lowers overall system maintenance.
