A post top fitter slips over a vertical pole or tenon and is secured with set screws. A pier mount bolts to a flat surface such as a masonry column, entry pier, or deck post. Many fixture families offer both mounts on the same lantern, so pick the body style first, then the correct mounting base.

Pedestrian-scale post lights typically run 8 to 14 feet, with 10 to 12 feet the sweet spot for walkways and entry drives. Larger commercial sites push to 16 to 20 feet for wider spacing. Lower heights need tighter spacing and lower output per pole to avoid glare at eye level.

Type III distribution suits paths along a perimeter, since it throws light forward and along the walkway with little spill behind the pole. Type V works for open plazas, intersections, and courtyards where symmetric coverage matters. Full cutoff versions of both keep light out of the sky and off adjacent property.

Many are, but not all. Look for full cutoff optics that emit no light above horizontal, and choose 3000K or warmer where local ordinances apply. Traditional acorn styles with drop lenses scatter uplight; modern LED acorns reproduce the look with shielded optics that meet most dark-sky requirements.

Solar post lights work for wayfinding, monument entries, and remote paths where running power is impractical. Their output is well below wired LED post tops and depends on daily sun exposure, so they are not a one-for-one substitute for wired area lighting where uniform footcandle levels are required.

Usually yes. If the existing pole has a standard 3 inch tenon and sound wiring, a new LED post top installs directly on it. Verify pole condition, tenon size, and voltage first. This is the standard approach for HOA and streetscape upgrades because it preserves poles and foundations.
