Can anyone identity this old Hayward fixture? Would the Duralite be the proper replacement?


A  Answered on 11/3/2021 by InyoPools Product Specialist Megan C.

Unfortunately, I am able to view the images up close. Are you able to reply back with images with a tape measure across the front of the faceplate showing the diameter and one down the side from the front of the faceplate measuring the depth to the end of the can? Do you see a label with a model or series number on it? What cord length, Volts, and Watts do you need?

Is it possible to replace the light housing while using the existing electric cable?

A  Answered on 6/1/2006 by InyoPools Product Specialist Patrick P.

You cannot use your existing light cable.  You will need to pull the new cord through the conduit on the new light.
