We prevent the factory to deliver 1,000pcs of 200W Highbay lights to the overseas buyer, by the inspection before shipment. More important is: We prevent our customer to face the challenge from the end users, who would use these IP failure products. Thank our QC's careful work. Thank the customer's trust, and they fully understand, support our quality process. Thank the factory's understanding and cooperation. We are unique Team, help buyer get reliable quality lights from China. Question: According to IEC60598, A or B, which one is more like a correct one? Is the distance between the Light and "Water gun" important?
