The front porch of this cottage faces north-northwest, which in the Cotswolds means it catches whatever the weather sends from the Bristol Channel. Three outdoor lantern sconces have come and gone since I moved in seven years ago. The fourth pair — installed 18 months ago — is the one I would recommend to anyone.
What Failed and Why
The first pair: powder-coated black steel, fairly cheap, IP44 rated. After one winter the coating had begun to bubble at the mounting bracket where water sits after rain. The rust was structural by spring.
The second pair: solid brass, beautiful in the shop, devastating in weather. The lacquer lasted exactly one season before the brass began oxidising green. I actually considered keeping the verdigris as a look — it suits the stonework — but the internal wiring housing had also corroded enough that an electrician told me to replace them.
The third pair: a premium brand, IP65, aluminium body, powder-coated anthracite. These lasted four years before the mounting back-plate cracked in an unusually hard frost. The lantern heads were fine; the plate that attached to the stone wall failed.
What I Have Now
Solid cast aluminium bodies with a powder-coated black finish over a zinc primer layer, IP65 rated, with a stainless steel mounting back-plate sold separately that I had a local ironworker fabricate to match the stone coursing. Eighteen months, two winters, one unusually wet spring. No rust, no bubbling, no cracks.
The mounting method is the detail I got wrong previously. Stone walls expand and contract differently from the mounting hardware. A rigid direct-to-stone mount eventually cracks at the fastening point. The ironworker used a lead plug system — expansion plugs set into the mortar joint rather than the stone face — which allows slight movement without transferring stress to the back-plate.
The Bulb Question for Outdoor Lanterns
I use a small golf-ball LED at 2700K inside each lantern. 250 lumens per fitting is enough for a porch — outdoor lanterns at full brightness near a front door create an unflattering upward-cast shadow effect on anyone standing below them. Lower lumens, warmer colour, more welcoming result.
I also put both sconces on a dusk-to-dawn photocell so they come on automatically. In winter this means they are on from half three in the afternoon, which matters for returning home in dark.
A Source Worth Checking
BO-HA's outdoor lighting range has lantern sconces worth comparing if you want something that arrives with an IP65 rating already verified and a finish tested for wet climates. Worth checking their current stock before committing to anything else.
The Lesson After Four Pairs
Buy the highest IP rating you can afford. Specify a separate, better-quality mounting plate. Use expansion plugs into mortar joints rather than stone faces. Keep the bulb wattage low. These four changes are the difference between replacing outdoor lanterns every 18 months and having a pair that genuinely lasts.
