IP67 on PC and aluminum housings

Almost every current Katuo product table prints Waterproof: IP67. That is a dust-tight, temporary-immersion rating on the finished lamp.

Warning mini bars and beacons use PC housings and PC lenses. Work lamps and forklift lamps use die-cast aluminum bodies with PC lenses.

Operating temperature printed across the warning and signal range is -40C to +65C.
