Product Identity
The Sylvania FT55DL/841 is a 55 W compact fluorescent lamp delivering 4800 lumens at a 4100 K colour temperature. It uses a single T5 tube with a 4-pin 2G11 base and is rated for 12000 hours of life. This bulb suits commercial or residential fixtures requiring high-output cool-white light.
Compatibility Check
Verify that the existing fixture accepts a 2G11 4-pin base and is ballasted for a 55 W T5 lamp. The physical length of the single tube must fit within the housing. Ensure the supply voltage matches the ballast specification before installation.
Build and Daily Use
The 800 series construction provides a colour rendering index of 82 for accurate colour representation. The 4-pin base locks securely into compatible sockets to prevent loosening from vibration. The 12000-hour rated life reduces replacement frequency in continuous-operation environments.

Questions about this item
What comes with the Sylvania FT55DL/841 55 W bulb and what must be purchased separately?
The box contains the single-tube 4-pin compact fluorescent bulb itself. A compatible 2G11 base ballast or fixture is required separately to operate the lamp.
How do I choose between the 800 series 4100 K version and other colour options for this 55 W model?
The 841 code identifies the 800 series phosphor at 4100 K neutral white. Select this version when you need 4800 lumens with a CRI of 82 for general lighting; choose a different colour code only if a warmer or cooler tone is specified.
What does the 4800 lumen rating mean once the bulb is installed in a fixture?
The 4800 lumen output is the initial light level delivered by the 55 W tube at 4100 K. Actual illumination on the work surface depends on the fixture optics and ballast factor, but the lamp is rated to maintain useful output for 12000 hours.
