The Litetronics PRT135 LED Light Panel Retrofit is designed to modernize interior grid ceiling installations by replacing traditional fluorescent troffers with a single, compact form factor. This 1x4 panel retrofit delivers high efficiency and flexible light output for 2×4, 2×2, or 1×4 fluorescent troffers, enabling an upgrade without ceiling demolition. With a 100,000-hour rated life and DLC Premium listing, it offers long-term energy savings and reduced maintenance compared with legacy fluorescent systems. The unit is built with field-adjustable output across five levels, allowing you to tailor lumen delivery and wattage to meet changing occupancy or task lighting needs, while helping to manage energy use without sacrificing performance.
Key performance characteristics include a 36-watt nominal draw, 4500 lumens of luminance, 3500K color temperature, and an 80 CRI, providing a solid, comfortable light quality for general interior workspaces. The retrofit operates across a wide voltage range (120–277V) and supports instant-on and dimming functionality, depending on compatible controls, with a beam angle of 110 degrees to ensure broad, even coverage. It is rated for damp locations, making it suitable for areas like warehouses, offices, and corridors that require reliable performance in variable humidity or moisture conditions.
For installation and lifecycle considerations, the PRT135 is designed to install quickly—up to two minutes for a single installer without accessing the ceiling plenum—reducing downtime during retrofit projects. Its DLC Premium status denotes compatibility with energy incentive programs in many markets, and the included 10-year warranty provides long-term protection aligned with industrial procurement expectations. When selecting this retrofit, verify compatibility with your existing luminaire housing and ensure appropriate mounting for your specific grid layout and ceiling thickness.
