Outdoor lighting makes using your deck much more enjoyable, but it can be expensive when you have to have an electrician come out and wire them. These Solar LED Stained-Glass Postcap for 4X4 Posts lights don’t need wiring because they have solar panels built in to charge the included 1 AA NiMh rechargeable battery that powers the 18-lumen warm-white LED light. The fixture has a brushed copper finish and plastic panels with a stained-glass look. The fixtures fit the top of a standard 4X4 post, or they can be mounted with the included side post bracket. The lights have a 120o beam spread; they come on automatically at dusk and stay on for up to 6 hours when fully charged. The Solar LED Stained-Glass Postcap for 4X4 Posts light is $15.90 from Pegasus Lighting.
