Industrial LED linear luminaires are an energy-efficient alternative to fluorescent lighting fixtures for both low bay and high bay applications such as manufacturing facilities, industrial halls, sports complexes, gymnasiums, warehouses, cold storage facilities, shopping areas and public buildings. Quality LEDs, superior thermal management and intelligent design contribute to high lumen maintenance and low total cost of ownership. The high return on investment makes these fixtures ideal for applications where long life, low maintenance, and improved nighttime visibility is required. The LED light source is typically mounted to an aluminum heat sink which is designed to maximize cooling effectiveness of the system. The most latest fixture designs come with modular LED bricks wired in parallel for ease of maintenance. Light distribution can be precisely customized to the specific needs through proprietary photometric design. The optical assemblies are often sealed for weather tight protection. Modern linear luminaires are IP65/66/67 rated with water- and dust-proof feature, suitable for use in lighting applications which could be prone to harsh conditions where dirt and moisture are present. The heavy duty housing is constructed of extruded or die-casting aluminum with anodized surface treatment for corrosion resistance. Wireless control and dimming technology are incorporated for greater energy savings and flexibility in lighting management.
