Hayward Lights

Thank you for your help. One more question. Is the lpcus11100 the same size as the lplus11100 or will I need a contractor to enlarge or close up the current space?
Sorry I was not more specific. I currently have Hayward lplus11100 white lights in the pool. I want to change them to the lpcus color lights. I wanted to know if they are the same size so I can take one out and put the new one in.

Should be.

Where are you buying the lights?
