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

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

I would like to know if the white plastic housing and the blue cover can be replace rather then the entire lamp. Pics attach.

Hello Ricardo, thank you for contacting INYO POOLS. The parts you would need would be the Blue Lens (79109000)  and the Face Ring Color Adapter (79210000).

    Thank you. Do you have a video instructions to just install those two parts and not the entire lamp kit?

      Hi Ricardo, Unfortunately, we do not have a video for the installation of the pool light ring and lens, however the process is quite simple. If you run into any issues please reach out to us and we can help walk you through the installation process.

        Do I need to lower the water for the Blue Lens cap to cover the lamp so it would be dry or I can just replace the two parts without lowering the water level?

        • Commented on 10/30/2020 by InyoPools Product Specialist Patrick P.

          No you will not need to lower the water. If you watch from the 2:20 mark to the 2:45 mark on our Video on How to Replace a Pool Light Fixture it will show you how to pull the light up onto the deck, where you then can install the new parts.
