The Litetronics VRT450N is a 50W, 5000K LED volumetric retrofit kit designed to upgrade existing 2x4 fluorescent troffers without requiring major ceiling work. It delivers up to 6,250 lumens with an impressive 125 lumens per watt, offering a substantial energy reduction compared with traditional fluorescent systems. The kit ships as a single unit and is intended to be installed into standard fluorescent troffers, with a patented design that supports quick, one-person installation in under two minutes and does not require breaking into the ceiling plenum. Once installed, the lighting can be controlled via the LiteSmart mobile app or an accompanying wireless remote, enabling on/off, dimming, and scheduling. The onboard sensors support occupancy sensing and daylight harvesting, allowing the fixture to adapt to space usage and ambient light, while also enabling batch control where multiple fixtures can be grouped to operate as a single lighting system.
This retrofit is suitable for a range of spaces, including offices, healthcare environments, retail areas, schools, hospitality venues, warehouses, and general commercial settings. The unit is designed for damp locations and is compatible with 120–277V electrical supplies, offering continuous dimming and a straightforward upgrade path from legacy fluorescent systems. It features a white finish and is RoHS compliant, with listings including UL, ETL, DLC, and DLC Premium, which supports verified performance and eligibility for utility-based energy incentives. Maintenance considerations are minimized by its long 100,000-hour rated life and the near-elimination of routine ballast replacements.
When planning replacement, verify that your existing troffer accommodates a 2x4 layout and that you have a means to access and route power during installation. The VRT450N’s wiring and mounting are designed for T-bar ceiling grids, and its modular approach enables rapid deployment with minimal disruption to occupied spaces.
