    Pool light wiring question

    Got a question that certainly has a quick answer.

    I'm replacing a couple of pool light assemblies and when I opened the J-box in the deck it was packed with a sort of putty.
    Makes sense, since it's protecting the connections, but what kind of putty/ packing is it exactly? Plumber's putty? Modeling clay?
    After many years it's still pliable.
    Any suggestions?

    Thanks, Pete

    I'll bet it's silicon grease. It's nonconductive, and protects the wires from oxidizing. And bleach is a strong oxidizer!

    MajorDIYer - Spot on I think, based on a read of your link.

    Richard320 - You're right, silicone grease is an excellent sealer. I was a little concerned it might migrate down the conduit. I can worry about anything!

    Thank you both for taking a moment to help.
