Description
Replacement Battery Backup LED T5 Linear Lamp - 48" - 22W - 3500K / 4000K / 5000K - 2900 Lumens - 120-277V
The Aleddra LLT-4-EM-T5-G2-22W-3CCT is a 2-in-1, ballast-bypass (line-voltage) T5 LED tube with an integrated emergency battery. It runs as a normal T5 lamp on AC power, then automatically switches to battery power during an outage to provide emergency illumination. This G2 version is designed for on/off applications and is operable by a wall switch, while offering 3CCT selection (3500K / 4000K / 5000K) for consistent color across mixed spaces.
Key Features
- 2-in-1 emergency T5 tube: Standard lighting + built-in emergency mode in one lamp.
