Turn Off Power to Light Fixtures

because um we made it dark so um challenge I don't want it to get hot I'm going to see hopefully there's going to be a light switch that turns this off cuz what I want to do is mask this right here like this so I don't get anything bleeding through green lights are really expensive a lot of lights are inexpensive if you break them or get paint on them easy to fix but that's an expensive light so it's like that I'm going to see the customer's not home so I'm going to see if there's an onoff switch I'll turn that
