IP Ratings: Where to Use What

An IP rating is a promise about one specific environment. Choosing one rating too low is the most expensive mistake on this list, because it fails after handover.

The IP (Ingress Protection) rating defines what a strip can survive. The first digit covers solids; the second, water. For LED strips you read the second digit.

Rating	Where	Examples
IP20	Indoor, dry only	Cove, under-cabinet, niche, stair
IP54	Damp / splash-protected	Bathrooms, covered porches, vanity
IP65	Outdoor, protected	Eaves, soffits, signage, façade
IP67	Outdoor, unprotected	Decks, hardscape, exposed façade
IP68	Continuous immersion	Pools, fountains, underwater steps

Rule of thumb: indoor dry = IP20; bathroom / kitchen splash = IP54; covered outdoor = IP65; exposed outdoor = IP67; pool / fountain = IP68.

Questions on this topic

Which IP rating do I need for an outdoor or wet location?

IP20 is dry indoor only. IP54 handles damp and splash locations such as bathrooms and covered porches. IP65 suits protected exterior positions like eaves and soffits, IP67 suits fully exposed positions such as decks and hardscape, and IP68 is the only rating for continuous immersion in pools and fountains. In the United States, also confirm the fixture and driver carry a UL or ETL listing appropriate to the location.
