OSRAM DULUX® F | 36W/840 | 217mm 2G10 Lumilux Cool White CFL Lamp

The Osram Dulux F 36W/840 is a high-efficacy, low-profile compact fluorescent lamp designed for modern area lighting. Its unique flat 4-tube design is specifically engineered for shallow surface-mounted or recessed luminaires, making it an ideal choice for 200mm and 300mm modular lighting systems. Delivering 2800 lumens of crisp 4000K Cool White light, this lamp offers superior luminous flux compared to using multiple lower-wattage bulbs, effectively reducing system costs and simplifying maintenance. With its 2G10 4-pin base, the Dulux F is a versatile solution for professional offices, public buildings, and commercial spaces requiring sleek, high-output illumination.

Superior Area Lighting Performance

The OSRAM DULUX® F stands out for its compact dimensions, being only half as long as a standard Dulux L lamp of comparable wattage. When operated with electronic control gear (ECG), it delivers approximately 13% higher luminous flux than a dual 18W setup, providing more light with fewer components. Its expanded spectral distribution ensures high light quality, making it a favorite for architectural downlights and shallow wall or ceiling fixtures.

• Modular Integration: Perfect for square recessed and surface-mounted luminaires (200mm/300mm).
• Economical Efficiency: Long 10,000-hour service life reduces replacement cycles and operational costs.
• Control Versatility: Compatible with both conventional and electronic control gear (ECG).
• Ultra-Slim Profile: Ideal for modern, shallow lighting designs where space is limited.
