Freezer emergency lights and exit signs are designed for use in environments where temperatures reach -40ºF (-40ºC). Standard cold weather emergency lights can only handle temperatures as low as -4ºF, but our freezer rated versions are designed with a much more powerful internal battery heater that allows operation in the coldest of environments. The emergency lights and exit signs below are designed for walk in freezers, cold storage facilities, and use outdoors in northern states as well as Alaska and Canada. You can be confident that the models shown below will perform properly in the harshest environments and in addition to being rated for freezing temperatures, they are also NRMA 4X rated for wet locations and hose down areas.
