As the below picture shows, regions in the Middle East and Africa are affected by direct sunlight all the year round, showing a state of high temperature.
For projects in these areas, they pay more attention to the temperature resistance of the product when selecting lamps. Indoors, the ambient temperature may exceed 50°C. For regular Highbay, it will not work properly at this temperature. So AGC brings up the specialized Highbay which can tolerant higher temperatures:
HB31 High-Heat 70°C Ambient Temperature
HB45 Ta70°C & Dust-Proof HighBay
