Solar Post Cap for RDI Excalibur Railing Posts
What It Is
The Excalibur Solar Post Cap is a solar‑powered LED post cap meant to be installed on top of an RDI Excalibur steel railing post (or other posts of compatible size) to provide automatic nighttime illumination without any wiring or external power. It enhances both safety and ambience around your deck, porch, or patio.
Key Features
Solar‑Powered LED Lighting
- Features an integrated solar panel on the top that charges internal rechargeable batteries during daylight.
- At dusk, the internal light automatically turns on and stays illuminated throughout the night without requiring wiring, transformers, or electrician help.
- Provides cool white light (around 5000 K) typical of RDI solar caps — bright enough for ambient accent lighting around posts and rail lines.
Easy Installation
- Designed to fit the Excalibur steel railing posts and other posts compatible with RDI’s post cap system.
- No electrical wiring, transformers, or low‑voltage landscape wiring required since it’s fully self‑contained and solar‑powered.
- Typically slides or mounts onto the post top for a clean, finished look.
Weather Resistant
- Built for outdoor use so it can handle rain, sun, and seasonal exposure.
- The construction (often die‑cast or similarly rugged material) is suitable for decks, patios, pergolas, and other outdoor structures.
