Litetronics PT2EB 120-277V 2—2 LED Light Panel With Integrated Emergency Battery Backup

The Litetronics PT2EB is a 2' x 2' LED light panel designed for grid ceiling installations, offering integrated emergency backup to maintain visibility during power outages. With a streamlined form factor, it installs into standard 2x2 grid layouts and provides continued operation for up to 90 minutes when mains power fails. The panel supports field-adjustable light output and color temperature, enabling customization of lumen levels across five settings as well as selectable CCT among 3500K, 4000K, or 5000K to suit different tasks and spaces. This flexible configuration helps balance energy use with occupancy needs while reducing maintenance frequency compared with traditional fluorescent systems. The unit operates at 120–277V and delivers up to 125 lumens per watt over a 50,000-hour rated life, contributing to long-term energy savings and reduced replacement intervals. A sealed enclosure helps keep dust and insects out, which is beneficial for damp locations where moisture exposure could affect performance. The fixture supports 0–10V dimming and uses an anti-yellowing frosted diffuser to maintain consistent light quality over time. Certified for damp locations, it is suitable for indoor environments where exposure to humidity is a consideration, and its 110-degree beam angle provides broad area illumination suitable for general lighting needs in interior grid ceilings.

The PT2EB combines high-efficiency LED performance with built-in battery backup, reducing the need for separate emergency lighting systems in applicable spaces. The unit carries a 5-year warranty, offering coverage for the light panel over its service life. When selecting this panel for a project, consider the installed ceiling grid size, the desired brightness level, and the preferred color temperature to ensure consistent lighting performance and emergency operation throughout the building. The product’s electrical requirements and dimming compatibility should be verified with your electrical designer to ensure proper integration with existing controls and power circuits.
