Everline RK LED RetrofitThe troffer reincarnated! Universal Lighting Technologies' EVERLINE® LED Retrofit Kit simplifies the transition from fluorescent to LED. LED technology reduces electrical demand and energy consumption compared to conventional fluorescent lighting systems, and also offers controllability, light uniformity, and less maintenance. Universal’s energy-saving and cost-effective EVERLINE RKL Retrofit Kit converts either a 2’ or 4’ fixture to LED lighting. Universal makes it easy to upgrade to LED technology with simple installation and industry leading efficiency with the reliability of their complete in-house design (electronic, thermal and optical) including EVERLINE® “matched” modules and drivers. Click here to see the Universal Everline RK Retrofit Kit Application Guide.

The LED EVERLINE® Retrofit Kit offers premium optical performance using a broad distribution angle to eliminate dark zones and a careful binning process to ensure color accuracy and consistency. Four light output options provide up to 6000 lumens per retrofit kit. Correlated color temperature (CCT) options include 3500K, 4000K and 5000K, all with a color rendering index (CRI) of 82 (nominal). The EVERLINE LED Retrofit Kit is fast, lightweight, and easy to install with standard tools and installation practices. In fact, no unusual tools are required. Universal’s simple install means you can make the best of your current lighting system because no redesigns or revised ceiling layouts are needed. See for yourself! Check out the short video below. 

This item is the Universal Everline 2-lamp LED  2x4 retrofit - part number LRK24-46L840-U. These LED Lay-in troffer retrofit kits include (2) 4000K LED Everline lensed modules and (1) Everline D10CC55UNVTZ LED 0-10V dimmable driver. EVERLINE®’s high efficiency LED drivers feature tuning, allowing you to design specific target lumen levels by programming the driver’s output current. Analog (0-10V) dimming provides control flexibility for the end-user for energy management or architectural dimming. The LED driver accepts a universal 120-277 volt input and all components are designed to install directly into your existing 2x4 troffer housing. As an added bonus - each LRK24-46L840-U retrofit kit is DesignLights Consortium™ QPL listed (DLC Product ID P9NFD1WB) and is UL Classified 1598C. There is no need to break into the plenum. The LED tubes are secured to the existing housing using double sided tape prior to completing the LED module installation with tek screws. Click here to see the Universal Everline RK Retrofit Kit Installation Instructions.

The LRK24-46L840-U 2x4 LED drop ceiling light fixture delivers 4,600 lumens of 4000K, 82 CRI light. This 2-light 2x4 retrofit option consumes just 43 watts and has a rated life of 50,000 hours (based on maximum 40 degree Celsius room temperature). The 2x4 LED panel comes with a 60 month limited warranty on the LED driver and a 36 month limited warranty on the LED modules. Suitable for indoor applications, they also carry the certifications of UL, FCC and RoHS. Click here to see the Universal Everline RK Retrofit Kit Product Brochure.

The Everline® Retrofit Kit breathes new life into existing recessed fluorescent troffers by upgrading them to cutting-edge LED technology quickly, easily, and economically. LED provides a superior alternative to fluorescent sources for troffers in commercial, education, healthcare, and other applications.
