The SLK22-40ML-EDU TRONIS TROFFER RETROFIT KIT is a versatile and energy-efficient solution for upgrading existing 24-inch T12 or T8 Linear Fluorescent lamp fixtures to modern and more powerful LED lighting. This retrofit kit is specifically designed for educational institutions and comes with various features that cater to the unique requirements of learning environments.
The SLK22-40ML-EDU kit includes 22 pieces of 29-watt, 4000K LED tubes. These tubes deliver a bright and consistent light output that closely matches the color temperature and quality of traditional fluorescent lamps. With a Color Rendering Index (CRI) of 80 and a Ra value of 80, these LED tubes can effectively render true-to-life colors and maintain excellent color consistency.
The kit is designed to be easily installed and requires no rewiring or modifications to the existing wiring. The retrofit tubes feature a unique twist-and-lock design that enables a secure connection to the ballast, ensuring a stable and reliable electrical connection. The LED tubes can also be installed in either the 2-pin or 3-pin positions, making them compatible with a wide range of T12 and T8 fixtures.
This retrofit kit is designed to provide significant energy savings compared to traditional fluorescent lamps. Each LED tube consumes only 29 watts, while a standard 40-watt fluorescent lamp consumes 40 watts. By replacing four 40-watt fluorescent lamps with this retrofit kit, you can save up to 112 watts of energy and reduce your lighting-related energy costs.
The SLK22-40ML-EDU TRONIS TROFFER RETROFIT KIT comes with a five-year warranty on the LED tubes and a one-year warranty on the electronic ballasts. This warranty covers defects in materials and workmanship, providing peace of mind and ensuring a long-lasting and reliable solution for your lighting needs.
In summary, the SLK22-40ML-EDU TRONIS TROFFER RETROFIT KIT is an excellent choice for educational institutions looking to upgrade their existing T12 or T8 Linear Fluorescent lamp fixtures to energy-efficient and long-lasting LED lighting. With its ease of installation, compatibility with various fixture types, excellent color rendering, and significant energy savings, this retrofit kit is an investment that will pay for itself over time while providing a brighter, more consistent, and more cost-effective lighting solution.
The SLK22-40ML-EDU TROFFER Retrofit Kit by SLK Lighting is a 24-piece set of T8 LED tubes designed to replace traditional 29-watt fluorescent tubes with a more energy-efficient and long-lasting alternative.

3. Color Consistency: The 4000K color temperature ensures consistent and uniform light output across all tubes.
4. Easy Installation: The retrofit kit is designed to be easy to install, requiring no rewiring or ballasts.
