IP rating and outdoor LED

An IP rating (Ingress Protection) is a two-digit code. The first digit is solids and dust. The second is water. Outdoor LED modules and cabinets are commonly sold around IP65: dust-tight and protected against water jets. The mark on the brochure only helps if the installed wall keeps that seal: gaskets seated, cable glands tight, drainage paths clear, and no field cuts that open the cabinet.

Canadian outdoor installs see rain, snow, freeze-thaw, and low winter sun. Brightness is a separate problem from weather sealing. Long-throw signs often need many thousands of nits so the picture survives daylight; see Brightness. Automatic brightness sensors cut the wall down at night so it does not glare into the street. Many municipalities expect that behaviour.

Sealing at both module and cabinet level is stronger than sealing only one of the two. Fanless outdoor designs avoid intake paths that pull weather and grit into the electronics. Front or rear service access has to be planned before the wall is welded into a structure you cannot reach.

The LED face is only half the system. Controllers, media players, and network gear need a dry, temperature-managed enclosure. Outdoor jobs often use a NEMA-rated box with heat and cooling, plus a brightness sensor that sees the same sun as the wall. Copper or fibre runs, PoE for a site access point, or a cellular modem are site choices, not display pitch choices.

IP rating is not electrical certification, and it is not structural engineering. You still need a recognized safety mark on the product and a mounting design that carries the load. See Electrical certification in Canada and Mounting and structure.
