An LED tri-proof light is an enclosed and gasketed light fixture that is designed for use in environmentally demanding locations. The term “tri-proof” means that the fixture is watertight, dust-tight and corrosion resistant. It’s a little bit of Chinese-style English. In fact, almost all tri-proof lights are constructed to be in a way that dust, water and vapor will not enter the enclosure, so they are vapor-, water-, and dust-tight. In contrast, a waterproof or dust-proof luminaire is so constructed or protected that water or dust might enter the enclosure but will not interfere with its successful operation. In North America, these types of light fixtures are called vapor tight fixtures.
Tri-proof lights have a diversity of use not found in other types of lighting systems. A vast variety of applications are accommodated by tri-proof lights, ranging from commercial, industrial and retail spaces to institutional buildings, hospitals to outdoor covered structures. In these facilities, lighting often needs to fulfill special requirements due to the presence of high humidity, dusty or corrosive atmosphere as well as splashing water, hosedirected water, spillage or other soiling with normal use. These environments are frequently seen in car washes, warehouses, parking garages, cleanrooms, food processing plants, stairwells, pool areas, sauna, laundry rooms, utility rooms, mechanical shops, industrial kitchens, livestock containment buildings, breweries, underpasses, tunnels, etc. The rugged, watertight lighting systems can be surface mounted to a ceiling or wall, or suspended by a chain, cable or stem.
