Product Overview
The GE 31953 F55BX/840 is a 55W 4100K Cool White 4-Pin High Lumen Biax® plug-in CFL rated at 4,800 initial lumens and 4,080 mean lumens, with a CRI of 82 and a rated average life of 20,000 hours. It uses a 2G11 4-pin base and is a plug-in lamp, so it must be operated on a compatible external 4-pin CFL ballast. Dimming operation is not listed in the GE catalog; do not install on a dimmer circuit unless the ballast manufacturer specifies compatibility.
GE catalog notes for this lamp: Fluorescent lamp lumens decline during life. Based on 60Hz reference circuit. 4-Pin lamp minimum starting temperature is a function of the ballast. Most ballasts are rated with a minimum starting temperature of 50°F (10°C). Ballasts are also available that provide reliable starting to 0°F (-18°C) and -20°F (-29°C). Life ratings are based on operating the lamp at 3 hrs. per start on a rapid start type ballast. Life rating on a preheat or instant start ballast is 25% lower. GE caution notice 151: CAUTION – Lamp may shatter and cause injury if broken. Remove and install by grasping only the plastic portion of the lamp.
Applications
- 4-pin CFL fixtures – Recessed downlights, wall sconces, and other fixtures built for 2G11 4-pin plug-in lamps. Confirm base, wattage, and ballast compatibility before ordering.
- Retrofit and maintenance replacement – Like-for-like replacement for 55W 2G11 lamps. 4100K (Cool White) matches the color temperature of the lamp being replaced when that lamp is also 4100K.
Replacing Your Current 4-Pin CFL?
- Base type – confirm 2-pin vs 4-pin: This lamp uses a 2G11 4-pin base. 2-pin and 4-pin lamps are not interchangeable. Check your fixture socket.
- Ballast compatibility: Plug-in lamp — requires a compatible external 4-pin CFL ballast rated for 55W and a 2G11 lamp. The catalog lamp table does not specify a ballast model.
- Wattage – 55W: Confirm your ballast and fixture are rated for 55W.
- Color temperature – 4100K: Match the color temperature of the lamps you are replacing.
- Dimmable: Not listed in the catalog. Do not install on a dimmer circuit unless the ballast manufacturer specifies compatibility.
- Catalog cross-reference: Generic FT55W/2G11/RS/841; Osram/Sylvania FT55DL/841.
