LED Backlit Panel Light with Emergency Backup

Engineered for high-efficiency commercial, educational, healthcare, and office space retrofits, this 2×2FT 40W LED Backlit Panel Light combines high-output, uniform illumination with built-in emergency backup protection. Producing 5,000 lumens at an energy-saving efficacy of 125 lm/W, this ultra-slim lay-in fixture serves as an ideal upgrade for legacy 2-lamp or 3-lamp U-bend and T8 fluorescent troffers. Outfitted with a factory-installed Emergency Battery Backup (EM) driver, it provides immediate, code-compliant egress lighting during unexpected power outages.
