The Orion Light is the first of Aurora's Deck Lights that uses a geometric shape in front of the glass creating a new element design. This new concept makes the Orion Light a beautiful accessory that adds another level of distinction regardless of the time of day. Made of solid cast aluminum, the Orion light and matching caps are designed for deck and fence post sizes from two through six and half inches. Designed to fit post widths of 3 1/2 in., 4 in., 5 1/2 in. and other sizes are available with conversion base. See chart.
