Product Overview
The GE Biax T5 18W is a compact fluorescent lamp engineered for high-efficiency commercial lighting. The single-ended twin tube design and 2G11 plug-in base make it a direct replacement in dedicated CFL fixture systems. At 3500K neutral white, this lamp produces balanced illumination — warmer than cool white (4100K) but crisper than warm white (3000K) — making it versatile across offices, retail, hospitality, and general commercial environments.
The 58V operating voltage and 2G11 base require a compatible dedicated CFL ballast — this lamp is not self-ballasted and will not operate in a standard screw-base socket. Verify your fixture's ballast type and voltage before ordering.
Compatible Applications
- Office and commercial lighting — Recessed troffers, wall sconces, and indirect lighting systems using 2G11 plug-in fixtures.
- Retail display and hospitality — Retail display cases, hotel corridors, and restaurant accent lighting.
- Facility maintenance and relamping — Direct replacement in existing 18W T5 2G11 CFL fixtures.
- Warehouse and utility lighting — General-purpose lighting in facilities using compact fluorescent systems.
Before Ordering — Verify
- Base Type: Confirm the fixture socket matches 2G11 4-Pin Plug-In.
- Wattage: Confirm the fixture and ballast are rated for 18W operation.
- Ballast Compatibility: This lamp requires a compatible dedicated CFL ballast rated for 18W T5 2G11 lamps. It is not self-ballasted.
- Voltage: Confirm the ballast outputs 58V lamp voltage.
- Physical Fit: Confirm 10.5" MOL fits within your fixture's clearance.
Safety and Handling Guidelines
- Correct Ballast Required: Use only with a compatible dedicated CFL ballast rated for this lamp. Incorrect ballast use can result in lamp failure, reduced life, or fixture damage.
- Not Self-Ballasted: This lamp cannot be installed in a standard screw-base socket or used without a ballast.
