The Litetronics RFM3T450B is a 2-by-4 LED magnetic retrofit kit designed to convert traditional fluorescent troffers to LED illumination without the need for a ballast. This one-piece retrofit snaps into the existing troffer and uses rare earth magnets at each corner for quick alignment and secure attachment after removing the old tubes and ballast. The kit features an adjustable wattage driver, offering three lumen settings to tailor brightness and energy use to your specific requirements, which can also help optimize rebates where applicable. A 12V accessory wire enables future connections to sensors for added control options.
Engineering focuses on delivering high-quality light with efficient performance. The retrofit provides 5500 lumens of retrofit output and 4375 lumens at the luminaire, achieving a reported lumens-per-watt around 157 with a color temperature of 5000K for a daylight-like appearance. It includes a color-rendering specification of 82 CRI, which supports better object and task visibility in common work environments. The unit is rated for a wide operating temperature range from -5°F to 95°F and is designed for 120–277V operation, enabling compatibility with a variety of building electrical systems. A 10-year warranty signals long-term confidence in durability and performance for facilities planning cycles.
Practical considerations include the instant-on and instant-bright characteristics, reducing downtime during maintenance and installation. The product is described as DLC Premium, and it carries UL and FCC designations, aligning with common safety and regulatory expectations for commercial lighting retrofits. When planning replacement projects, verify that your 2×4 LED magnetic retrofit fit is compatible with your existing troffer housing and ballast removal steps, and consider how the selectable wattage settings might influence initial brightness, energy consumption, and rebate eligibility.
