These silicone filled wire nuts do work well for landscape lighting purposes. The silicone resists water entry and prevents oxidation. One thing that helps out a lot with this type of installation is orienting the wire nuts so that water can drain out if it does happen to get past the silicone.By: Jacob Carr 2018-01-02
