Litetronics VRT135N 1X4 LED Smart Volumetric Retrofit - 3500K

The Litetronics VRT135N LED Volumetric Retrofit is designed to upgrade existing fluorescent troffers to efficient, network-enabled LED lighting without major ceiling disruption. This 1x4 retrofit kit integrates an on-board sensor for occupancy sensing and daylight harvesting, enabling automatic, energy-conscious lighting control in interior grid ceiling applications. With up to 125 lumens per watt and a 100,000-hour rated life, it delivers strong, long-term energy savings and reduces maintenance, as it eliminates routine lamp-and-ballast replacements in standard troffer layouts.

Construction and features focus on quick, one-person installation and flexible control. The patented design supports standard fluorescent troffer sizes (including 2x4, 2x2, and 1x4) and installs in less than two minutes without breaking the ceiling plenum. After installation, the LiteSmart mobile app allows grouping of fixtures as a single control zone, enabling on/off, dimming, and scheduling, with settings pushed live to the field. The kit also offers practical convenience through a wireless remote switch, enhancing the ability to adapt lighting to changing space needs without extensive rewiring.

In terms of compatibility and performance, the VRT135N operates at 120–277 VAC and provides a 36W input with a 110° beam angle suitable for general task and ambient illumination. It is designed for damp locations and carries features such as DLC Premium and FCC compliance, with a 10-year warranty for long-term confidence. Consider this retrofit when upgrading aging troffers in offices, schools, and light-commercial interiors where energy efficiency, simple installation, and modern control capabilities are priorities.
