The vapor proof led light fixture is used for indoor lighting or shed lighting , also it's designed IP65 , but fewly used for outdoor lighting .
Vapor means a substance diffused or suspended in the air, especially one normally liquid of water or oil , and if the fixture is not IP65 , the vapor gets into the vapor proof led light fixture body , it will harm the electronic parts of the driver , also the LED maybe defective if the sulfide gets into the lamp body , so the life time of the weather proof led fixture will be shorter .
