IP66 is an international standard that indicates the level of protection provided by an electrical enclosure against the ingress of solid objects and liquids. The “IP” stands for Ingress Protection, and the “66” indicates the degree of protection. An IP66 rating means the enclosure is completely dust-tight and protected against powerful water jets from any direction. It signifies a high level of protection against dust, dirt, and water intrusion, making it suitable for outdoor lighting fixtures exposed to harsh weather conditions. IP66-rated fixtures are designed to withstand heavy rain, snow, and other environmental elements while maintaining their functionality and durability.

You can find all LED lights which are IP66 waterproof with this tag.
