RK91 - LED Retrofit In-Grade

The RK91 Retrofit Kit is an innovative solution for seamlessly transitioning existing Hydrel® 9100 Series fixtures to the advanced, energy-efficient Vista LED technology found in the 1188 series. This retrofit kit is designed for ease of installation, eliminating the need to disrupt concrete or hardscapes, thereby saving significant time and effort in commercial settings such as hospitality or theme parks. The RK91 maintains all the high-performance features of the 1188, including Chip-On-Board (COB) LED technology, precision optics, and various light distributions with controlled cutoff. It offers more than 3000 delivered lumens in color temperatures from 2700°K to 5000°K and is IP68 rated. The RK91 Retrofit Kit not only replaces outdated halogen lighting but also enhances it with greater longevity and reduced energy consumption.
