18W G24d-2 fluorescent bulb

The Sylvania CF18DD/841/ECO is an 18W compact fluorescent lamp with a G24d-2 two-pin base. It produces 1150 lumens of cool white light at 4100K with a colour rendering index of 82. Rated life is 10000 hours. It is designed as a direct replacement for compatible downlights and recessed fixtures.

Best for cool-task lighting

Suits offices, kitchens, retail displays and other spaces where a neutral 4100K output is preferred. Not suited for buyers who need a warmer colour temperature, a dimmable lamp, a different pin configuration such as G24q, or higher lumen output than 1150.

Fits G24d-2 magnetic ballasts

The two-pin G24d-2 base connects to magnetic ballasts already present in many commercial fixtures. No external starter is required. The lamp frees up the need for separate starters and operates on the existing control gear. Verify that the fixture accepts 18W lamps and the G24d-2 base before installation.
