I am going to use them in my bathrooms that have a grid ceiling with see through panels and florescent lights I will install them and use recessed lights that will give it a modern look I need to have access to the bathroom ceiling as there is plumbing from the upstairs condo that runs through the bathrooms Hopefully that will never happen.I purchased some samples a couple of months ago to see how they worked in a damp and wet environment and they passed my test
