Mary Modern Geometric Aluminum Post Cap Light, Matte Black

A fence line or gate pillar can do all the right things structurally and still look unfinished on top — bare metal or a flat cap that vanishes the moment the sun goes down. Mary corrects that: an inverted pyramid cast in solid aluminum, its four faceted planes catching daylight edge-on like a small piece of geometry, then glowing evenly along the base once the sun sets. It's sized to sit flush on a standard post or pillar, no adaptor or extra hardware required.

The powder-coated black finish is what keeps that geometry looking sharp — rain beads and runs off rather than staining, and the coating resists the chipping and fading that leaves a plain aluminum cap looking tired within a season. Because it's sold individually or in sets, you can light a single entry pillar or run the same fixture down an entire fence line for one continuous, matched look after dark.

Features

• Faceted pyramid form — a genuinely sculptural cap shape, not a flat lid with a bulb hidden inside.
• Solid cast aluminum — powder-coated to resist rust, chipping, and fading through repeated seasons outdoors.
• Two scales, three pack sizes — a 12-inch/30.5cm 6W cap or a 16-inch/40.6cm 8W cap, each sold as 1, 2, or 4 pieces so a whole run of posts matches.

Covering your run of posts

The built-in LED lights roughly 10–15 square metres per fixture, which is enough for a gate post or a single pillar on its own. Spacing several along a railing or driveway is exactly what the multi-packs are for — buy a Set of 2 or Set of 4 and every cap on the run lights, and looks, the same.

Available sizes

Specifications

Each cap is hardwired, so have an electrician run the wiring, or fit it yourself if you're already comfortable working with post lighting circuits — it's a repeatable, straightforward job once the first one's up. Installation notes are available on request at info@clerachic.com.

Frequently asked questions

Which size should I choose for a standard fence post?
The 12 in/30.5cm version suits most fence and railing posts; save the 16 in/40.6cm size for wider pillars or a statement entry post.

Do I need one fixture per post?
Yes — each cap covers 10–15 square metres on its own, so buy the Set of 2 or Set of 4 to match the number of posts you're lighting.

Is IP54 enough for an exposed gate post?
IP54 protects fully against dust and against water splashed from any direction, which covers open-air posts and pillars in normal weather.
