The AOK iH Series linear high bay luminaires are engineered to deliver the most reliable performance and bring across many benefits of LED technology in open ceiling lighting applications. The high performance luminaire is designed for a multitude of industrial and commercial lighting applications, including warehouse lighting, manufacturing facility lighting, and other interior environment where robust lighting performance with an extremely attractive ROI is highly desired. AOK iH Series high bay fixtures produce up to 26,300 lumens with a system luminous efficacy of more than 130 lm/W. These 24-inch fixtures incorporate LUXEON 3030 2D LEDs that delivering high intensity output with superior lumen maintenance. A constant current Mean Well driver accommodates 100 to 277V (347VAC and 480VAC optional) input at 50/60Hz. The driver provides excellent power factor correction (0.94 at 277V) and offers a high full load efficiency (greater than 90%). Reliability and efficiency are ensured by a die cast luminaire housing with an integral heat sink designed to offer better thermal ventilation and heat dissipation that allow up to 50°C ambient temperature ratings. The IP65 rated weather-tight housing protects the light assembly and electronic components from dust and water ingress. Multiple dimming options including 1-10V, PWM and resistive dimming provide additional energy savings. The compatibility with network protocols and smart lighting modules provide flexibility for use in multiple fixtures.
