YIOMAU YL-HB pro High Bay light is especially designed for indoor lighting with height more than five meters such as factory， warehouse， stadium， supermarket，airport buildings， etc.

High brightness LED lamps are adopted to make YIOMAU YL-HB pro. The LED lamp efficacy is up to 130lm/W. The usage of second lens assures the uniformity of illuminance and chromaticity on the ground surface. And three kinds of light distribution (W/ N/ R) can be chose for different lighting environment. The junction temperature is lower than 65℃， effectively controlling the light decay and prolonging the lifetime more than 50‚000 hrs.

The high reliable and intelligent driver and professional heat sink design technology assures the working temperature of the electronic components is not higher than 60℃， the power efficiency is very high， life time is more than  50‚000 hrs.   

        The intelligent function of electronic anti-reverse connection and automatic switch off which could be caused by the higher or lower supply voltage assure the safety of the light，and the perfect protection of over current， overvoltage and overheat function enhance the reliability. Meanwhile， such electronic driver design also provides several flexible and advanced control functions such as timer control， temperature control，photo sensor control， acoustic sensor control and internet control etc.
