Product Overview
The Sylvania 20712 FPC22/835 is a professional-grade 22W T5 Pentron® Circline fluorescent lamp engineered for high-frequency electronic ballast systems in residential ceiling fixtures, commercial low-profile luminaires, and architectural surface-mount applications. Delivering 1,800 initial lumens of 3500K neutral white light at 82 CRI through a 9-inch circular T5 tube profile, this lamp outperforms legacy T9 rapid-start circline lamps in both lumen output and energy efficiency — with a 12,000-hour rated life and a 2GX13 4-pin base featuring pins configured on opposite sides of the tube collar for secure single-ended plug-in installation.
| Wattage 22W T5 Circline | Initial Lumens 1,800 lm 82 CRI | Color Temp 3500K 835 Neutral White | Base Type 2GX13 4-Pin Opposite | Rated Life 12,000 Hr Pentron® Series |
ADL Supply Expert Application & Replacement Guide
The Sylvania FPC22/835 Pentron Circline is primarily specified by electrical contractors and facility maintenance teams replacing legacy T9 circline lamps in residential kitchen flush-mounts, bathroom ceiling globes, vanity rings, commercial hallway fixtures, stairwell luminaires, and architectural circle-pendant ceiling systems. The T5 tube profile (5/8-inch tube diameter) is significantly slimmer than the T9 circline format it replaces, providing superior lumen-per-watt efficacy within the same 9-inch nominal fixture opening. The 2GX13 base uses a 4-pin configuration with two pairs of pins positioned on opposite sides of the base collar — this is distinct from the GX10q or G10q bases used on some other compact circular fluorescent formats, and the socket must be confirmed as 2GX13-compatible before ordering. This lamp requires a dedicated high-frequency electronic ballast and will not operate correctly on magnetic ballasts or any standard line-voltage socket — confirm your fixture uses a compatible electronic CFL ballast rated for 22W 2GX13 circline lamps before installing.
Before You Order
| Verify Before Ordering 2GX13 Socket Required — Electronic High-Frequency Ballast Only | Not Compatible with Magnetic Ballasts This lamp requires a 2GX13 4-pin socket and a high-frequency electronic ballast rated for 22W circline operation. It will not operate on magnetic ballasts or standard line-voltage sockets. Confirm your fixture socket is 2GX13 (pins on opposite sides of the collar) before ordering — do not confuse with GX10q or other compact circular CFL base types. Confirm your ballast is rated for the 22W 2GX13 T5 circline lamp type. |

Operation, Safety & Mounting Compliance
Electronic Ballast Requirement & Base Compatibility
This lamp is designed exclusively for high-frequency electronic ballast systems — the high-frequency drive eliminates the 60Hz flicker associated with magnetic ballast operation and optimizes the tri-phosphor coating's lumen output and color stability. Magnetic ballasts will not correctly drive this lamp's starting and operating electrical parameters, resulting in non-ignition or severely shortened lamp life. The 2GX13 base orientation, with pin pairs positioned on opposite sides of the collar rather than clustered on one side, is a key differentiator from other compact circular fluorescent base types — verify the fixture's socket type against this specification before installation.
Mercury Content & Disposal
This lamp contains mercury and must be recycled or disposed of through a certified lamp recycling program in compliance with applicable federal, state, and local environmental regulations — do not discard in standard municipal solid waste. Certain states including CA, CO, HI, ME, MN, OR, RI, and VT may have additional restrictions on fluorescent lamp shipment — confirm shipping eligibility for your location before ordering.
