A post light is the fixture that marks an address. It sits at the end of a driveway or beside a front path, and it is usually the first thing a visitor sees at night.
Height and placement
Driveway entrance — 6 to 7 feet to the top of the fixture. Tall enough to see from the road.
Along a front path — 5 to 6 feet, spaced 10 to 15 feet apart.
Beside a garage — match the height of the garage door trim so the two line up.
Scale matters more than people expect. A post lantern that looks large in a showroom often looks small once it is 6 feet up and surrounded by open sky. When you are between two sizes outdoors, take the larger one.
What survives outside
Material
Best for
Cast aluminium
Coastal and humid climates — will not rust
Solid brass
Anywhere; develops a patina rather than corroding
Cast bronze
Freeze and thaw climates
Powder-coated steel
Dry climates, lower budget
All post lights must be wet rated. There is no covered-location exception out in the open.
Dark sky and neighbours
A shielded fixture aims light down where it is useful instead of sideways into a bedroom window. Many towns now require it. Even where it is not required, it is the difference between a lit path and a glare source.
