Stuck Light Bezel

I have an inground pool and my light has gone out. I started by unscrewing the one screw holding the light bezel in but now the light bezel will not budge! Ive slid screw drivers into the side to try and wedge it out and still no luck. The lens has now cracked so everything inside is getting wet. Anyone know any other ideas to get the bezel off?

I hope someone can help you. I know nothing about IG lights, but be SURE not to turn them on and turn off the breaker.

It sounds like there is something else holding the light in. Can you turn it clockwise or counter-clockwise in case there's a latch holding it in place?
