The 1188SE COB In-Grade Fixture 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 the rotation of internal tilt optics without opening the fixture. Ventilated flow-through 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. Corrugations in the housing also facilitate air-cooling inflow/hot exhausted air outflow. Four light distributions are available with outputs of more than 3000 delivered lumens in color temperatures from 2700°K to 5000°K.
