Litetronics RFM3T440B 2—4 3-Tube LED Magnetic Retrofit - 4000K

The Litetronics RFM3T440B is a 2x4 LED Magnetic Retrofit kit designed to upgrade a fluorescent troffer to solid-state illumination without removing the housing. This one-piece retrofit uses corner magnets for quick alignment and attachment inside the existing 2x4 troffer, replacing traditional tubes and ballast with an integrated, multi-wattage driver. The kit provides 5500 retrofit lumens (4375 luminaire lumens) with a color temperature of 4000K, delivering a neutral cool-white light suitable for general office and industrial spaces. It is rated with a CRI of 82 and a high power factor, offering efficient performance suitable for commercial environments that require reliable color rendering and energy savings. The module is built to operate within a wide input range (120–277V) and is designed for long life, with an average rated life of up to 100,000 hours. The product includes features such as instant on and instant bright operation, with dimmability to support lighting control strategies. A 10-year warranty underscores its expected durability and long-term value for facility managers.

This retrofit kit is marketed as not requiring a ballast, simplifying installation by eliminating the fluorescent ballast step. The 35-watt nominal configuration (adjustable via the driver) can be matched to existing energy-use targets and rebate programs that reward LED upgrades. The RFM3T440B is designed for compatibility with 2x4 troffer housings, and its magnetic mounting streamlines alignment during retrofits. Maintenance considerations include periodic checks of the magnet integrity and ensuring the fixture remains within its listed operating temperature range of -5°F to 95°F for optimal performance. Packaged as a single unit, the kit is intended for retrofit projects where a straightforward, ballast-free LED conversion is desired.
