You would need to open up the light to confirm which bulb version you have. You can always use the serial number as well and contact Pentair directly but for all of that you may as well just open it up.

My light looks just like the one that is pictured. I think its a 4 inch light. You have a s/n 77164100 for this light. When I look at the dimensions it shows in cone shaped. Is that right? Just want the right light. My light has series 77XXXX, watts 250, volts 120, bulb type T-4.
