The RK97 COB In-Grade LED Retrofit Kit from Vista Architectural Lighting utilizes integrated Chip-On-Board (COB) LED technology and precision optics to achieve high performance distributions of various spreads with controlled cutoff. A patent-pending magnetic hot aiming system allows for the rotation of internal tilt optics without opening the fixture. Ventilated flow-through door design allows cool air to enter and hot air to be exhausted from the Rough-in Section (RIS) to improve cooling of the LED module.  Four light distributions are available with outputs of more than 3000 delivered lumens in color temperatures from 2700°K to 5000°K.
