This set of two Classy Caps Imperial Black 4.5 Solar Post Cap Lights will fit your deck posts that measure 4.5" x 4.5". They have a low profile design, with rugged, maintenance-free powder coated cast aluminum housing, and non-yellowing, curved Plexi-Glas lenses. No electrical wiring or generator is required, all you need is the free solar power from the sun.

The solar fence post lights are easy to install, using the pre-drilled holes and provided hardware, and you will receive up to 10 hours of light duration at night.

A Volume Discount of 10% to 20% will be automatically applied with a 3 Set Minimum Purchase of solar deck cap lights. See breakdown below.

With your purchase, you will receive a set of two Black 4 x 4 solar fence post cap lights and two 4.5 x 4.5 mounting bases. You will need to take off the 4" mounting base, and install the 4.5" mounting base in order for it to fit your builder's 4.5" fence posts, such as Trex uses for their decking.

To change the mounting base, you will need to remove the lid by twisting it to the Left, then remove the 4 screws in the corners that hold the mounting base to the post cap light. Line up the 4.5" mounting base to the screw holes, and reinstall the four screws. Don't forget to take the reflector from the 4 x 4 base, and place it in the indentation in the new 4.5 x 4.5 base.

If you love this style but need a different color, we also have the Imperial 4.5x4.5 in a White or Bronze Aluminum powder coated finish.

    The trex brand lights are very expensive and had poor reviews. These lights were very easy to change the adaptor to fit my trex deck posts. They are bright and lit up the entire night with little time to charge the first night.
