Trouble removing pool light fixture

[mackics]

I'm having a difficulty in removing my pool light fixture. I unscrewed the single screw that holds the fixture (see attached image), but the fixture does not budge. I tried lightly prying it with a screwdriver, but no success. What am I missing? Is there a trick to removing these? All of the YouTube videos make this look like a simple job, so I must be doing something wrong.
Any help is much appreciated.

Welcome to TFP.

The light has a tab on the bottom and should pull out from the top after the screw is removed.

You never know if someone used silicone around the rim or something else that is sticking to it.
