The required ingress-protection rating depends on moisture, spray and cleaning practices in the facility. Higher IP ratings provide more protection against dust and water, but the exact number should be selected from the environment—not assumed from the word “commercial.”
Overhead spray, fogging, leaks and washdown can expose fixtures and connectors to water. Mounting location and orientation influence exposure just as much as the room type.
An IP-rated fixture connected with unprotected adapters can still create a weak point. Cables, connectors, dimming hardware and junction boxes need suitable environmental ratings too.
For “What IP Rating Should a Commercial Grow Light Have?,” these three models give you concrete products to compare against the requirements above, instead of leaving the answer at theory.
Our strongest starting point because its bar-style led / dimmable high-output fixture format makes it relevant when translating the lighting metric above into a real fixture choice.
A useful second comparison because its multi-bar led / dimmable format makes it relevant when translating the lighting metric above into a real fixture choice.
A contrasting third option because its high-output full-spectrum led / dimmable format makes it relevant when translating the lighting metric above into a real fixture choice.
