Is the Easy Plant LED light waterproof or water-resistant? Can I use it underwater?

The Aquarium Co-Op Easy Plant LED is highly water-resistant, but it is not designed to be used underwater. The IP67 rating means it is totally protected against dust and is protected from the effects of temporary immersion between 15 cm and 1 m depth. In practical terms, this means that if you accidently knock the light into a tank or it gets sprayed with water from an air stone, it will continue operating. This product has a 3-year warranty, and we focused on making sure that every feature lends itself to longevity.

Note: The controller and power adapter are not water-resistant and should not get wet.
