Trying to figure out how to install the 5g into my pentair quickniche. Nothing seems to match up right. I thought the light would actually be inside the niche but the only way i can get it close to working is if I install the niche faceplate and then the 5g light on top of that. It doesn't seem very sturdy that way and just doesn't seem right. Does this sound right to anyone or has anyone had this issue?
