IP rating: what comes before style in an outdoor wall light
An exterior light fixture has to stand up to rain and dust. That is what the IP rating measures. The first digit indicates protection against solids, the second against water. A waterproof outdoor wall light under an overhang or a porch needs at least IP44, which protects against splashes. On a wall exposed to driving rain or the spray of a garden hose, aim for IP65. Check the rating listed on each product page and respect it for the chosen location.
