The eye broke and I cannot get the screw to hold at top of light! Is the mounting ring a two piece so that I can replace the outer ring instead of taking the entire light out. All I need is the top screw hole so that I can mount the light In place And lock it into place!

I currently have the old SAM pool light with the wheel. Sticker states series 600015, 600016, 600017, 600022. Watts 165 Volts 120 Bulb Type MR16 75W. I need 150' replacement. What I am not sure on is do I need 300W or 500W and what is the difference? Thanks

Hi, Andy. You can replace your existing SAM light with either a 300 or 500 watt Amerlite fixture depending on your preference. The brightness and energy consumption are the difference.
