Imperial Solar Post Cap 2 Pack

The Imperial Solar Post Cap is a solar-powered LED light designed to fit over standard 4x4 or 3.5x3.5 wooden posts. It provides automatic dusk-to-dawn illumination for decks, fences and pathways. The pack contains two caps, each finished in black powder-coated cast aluminium for weather resistance. Ideal for homeowners wanting low-maintenance pathway lighting without wiring.

DIY installation with included adaptor

Installation is a simple do-it-yourself task: place the cap over the post and secure it with screws (not supplied). The 3.5x3.5 adaptor is included in the box for smaller posts. The only common issue is insufficient sunlight on the solar panel, which reduces the 10-hour runtime. Ensure the auto-off switch is set to on after mounting.

15 lumen output at 4500-5500K

Each cap delivers 15 lumens of white light at a colour temperature between 4500 and 5500 Kelvin. This brightness level suits accent and way-finding roles but will not replace a floodlight or security fixture. Buyers needing higher lumen output or a wider beam spread for area lighting should look elsewhere.

Questions about this item

How can I confirm the Imperial solar post cap is working correctly after I install it?

After dark the cap should light automatically; the 15 lumen LED at 4500–5500 K will stay on for up to 10 hours if the AA Ni‑MH battery charged fully in sunlight.

What comes in the 2‑pack box and is anything else required?

Two black cast‑aluminium caps, two AA Ni‑MH rechargeable batteries and a 3.5″ × 3.5″ adaptor for smaller posts are included; no extra parts are needed.

Which version should I choose for a true 4″ × 4″ post versus a 3.5″ × 3.5″ post?

Each cap fits both sizes — slide it onto a 4″ × 4″ post directly or use the supplied adaptor for a 3.5″ × 3.5″ post.
