A commercial-grade high bay light is designed for use in environments with undemanding operating conditions, such as those found in big box stores, retail outlets, auto showrooms, commercial warehouses, convention centers, exhibition venues, leisure centers, sports halls, and gymnasiums. Unlike industrial facilities that are often notoriously challenging to illuminate, these environments are generally absent of lighting challenges such as extreme ambient temperatures, dirty power, vibration from large machinery, high humidity, corrosive atmosphere, caustic chemicals, and dust. Today, the high bay lighting market is witnessing a rapid switch from fluorescent and HID technologies to solid state lighting based on LED technology. The complex composition of LED lighting systems causes product design to sway in different directions. Commercial-grade high bay LED lights are a distinctive category of products that are designed with application-specific priorities.
