The HB165 LED high bay lights from Feiert Technology feature minimalist industrial design that provides a distinctive architectural solution for commercial buildings and industrial facilities with middle to high open ceilings, including warehouses, indoor sports arenas, car dealership showrooms, convention centers, supermarkets, retail stores, restaurants, mechanic shops and airport terminals. Rugged construction and excellent heat management maximize application efficiency and consistent performance over the life of the fixture. The open heat sink design allows ample air flow through the fixture to ensure long LED life with extended lumen maintenance. The vertical orientation of the driver housing offers improved thermal dissipating performance and makes it less likely to trap dust and dirt. The HB165 LED high bay lights use an array of high brightness, high efficacy Nichia LED chips with a minimum CRI of 80 Ra and luminous efficacy of 120 lumens per watt. Precision-molded acrylic lenses are indexed to the circuit board to ensure consistent optical alignment to ensure precise photometric distributions, improved uniformity and enhanced glare control. Optional integral sensor and dimming system provides occupancy and daylight harvesting for additional energy savings and flexible light control.
