Litetronics RFM2T450A 2—4 2-Tube LED Magnetic Retrofit - 5000K

The Litetronics RFM2T450A is a 2×4 LED magnetic retrofit kit designed to replace fluorescent troffer lamps without removing the existing fixture housing. This one-piece retrofit uses corner magnets for quick, tool-free installation after the old tubes and ballast are removed, aligning itself within a standard 2×4 troffer. It features adjustable wattage via the onboard driver, offering three lumen output settings to tailor brightness and energy use to the application, which can also help in qualifying rebates. The kit includes a 12V accessory wire option for future integration with sensors or other control devices, enhancing compatibility with smart or automated lighting systems. Supported by a DLC Premium designation, the retrofit emphasizes efficiency and performance while maintaining instant-on and instant-bright behavior typical of LED upgrades.

Technically, the unit operates on a 120–277 V supply and delivers retrofit-level lumens around 4,700 with luminaire output near 3,750, achieving a favorable lumens-per-watt efficiency in typical installations. The LED source provides a color temperature of 5000 K and a color rendering index near 82, suitable for general ambient lighting in offices, classrooms, and retail spaces that prefer a cooler, daylight-like appearance. The component carries UL and FCC compliance indicators and is designed for broad operating temperatures from -5°F to 95°F, supporting reliability in varying environments. Its 10-year warranty offers long-term assurance, aligning with expectations for retrofit solutions that reduce maintenance and energy costs while preserving fixture form factor.

When planning use, verify that your existing fluorescent troffer can accommodate a magnetic retrofit and that the fixture’s electrical system can be configured to the selected wattage setting. The dual-lumen, 2×4 footprint means a straightforward swap in compatible troffers, reducing ballast-related downtime. For maintenance, the kit is designed as a drop-in replacement that minimizes fixture downtime during upgrade projects, while the included features like dimmability and the potential for sensor integration provide flexibility for future control strategies.
