Fluorescent Bulb for Electronic Ballasts

The Sylvania FT36DL/835 is a 36W long twin-tube fluorescent bulb with a 4-pin 2G11 base designed for electronic ballasts. It delivers 2900 lumens at a 3500K colour temperature with a CRI of 82. The bulb is rated for 12000 hours of life and measures 16.6 inches overall.

Replaces 36W 2G11 Compact Fluorescent Lamps

This bulb directly replaces existing 36W 2G11 base compact fluorescent lamps in compatible fixtures. The upgrade is worth it when the current lamp has reached the end of its rated 12000-hour lifespan or when light output has noticeably diminished. It maintains the same wattage and pin configuration for a straightforward swap.

2900 Lumens for General Commercial Lighting

The 2900 lumen output comfortably handles general illumination in offices, retail spaces, and institutional settings using electronic ballasts. The 3500K colour temperature provides a neutral white light suitable for task areas. It runs out in fixtures requiring higher lumen packages, different base types, or magnetic ballast operation.

Questions about this item

Will the 16.6 inch long twin tube fit my 2G11 socket?

The bulb measures 16.6 inches overall and uses a 2G11 four-pin base, so it fits fixtures designed for that exact length and base type.

How do I install this 36W 2G11 bulb without damaging the pins?

Align the four pins with the socket keyway, push straight in until the base seats firmly, and avoid twisting the long twin tube during insertion.

When should I replace this 12000 hour 3500K fluorescent bulb?

Plan replacement around 12000 hours of operation; light output will gradually decline and colour may shift from the original 3500K as the tube ages.
