Formed Plastic Acorns

KASTLITE formed plastic acorns are post top globe replacements shaped in the traditional acorn profile used on streetlights, park fixtures, and residential lamp posts. We manufacture these in clear polycarbonate and white polyethylene, both with 4" fitter necks that fit standard post top bases. The acorn shape directs light downward and outward, which makes them popular for walkway and driveway lighting where even ground coverage matters.

Materials: Polycarbonate vs Polyethylene

Our clear polycarbonate acorns (FP108PCC) are virtually unbreakable and allow full light transmission. They are the best choice for areas prone to vandalism or storm debris. The white polyethylene acorns (FP108PEW) diffuse light more softly and hide the bulb from view, giving a cleaner appearance during the day. Polyethylene is also lighter, which puts less stress on the fitter and post.

We also carry a mid-size polycarbonate white acorn (FP107-9PCW) for smaller post top fixtures. Each model page lists the exact height, diameter, and neck dimensions.
