Are rattan pendant lights suitable for outdoor use?

Real rattan is a natural palm fibre, and it behaves like a sponge. Left exposed to rain, humidity, or morning dew, the fibres absorb water, swell, split along the weave, and develop black mould spots that cannot be cleaned out. Even under a fully enclosed porch, condensation alone will degrade untreated rattan within a couple of British winters. Natural rattan belongs indoors — in a conservatory with stable humidity, or a dry covered veranda in a sheltered climate. For anything beyond that, specify a purpose-built outdoor pendant light with an IP44 rating or better. Every fitting in our outdoor pendant lights range is sealed against splashing water and rated for exterior installation, which is the baseline a natural rattan shade simply cannot meet. If you love the woven look, the honest answer is to buy a rattan-effect fitting made from polyethylene or resin wicker, which we cover in detail below. The price difference is small; the lifespan difference is years.

The IP (Ingress Protection) rating tells you exactly what a fitting can withstand. The first digit covers solid objects, the second covers water. IP44 means protected against splashing water from any direction — sufficient for a covered porch, doorway recess, or pergola where rain never falls directly on the fitting. IP65 means protected against jets of water, which is the practical minimum for pendants hanging in open weather. Anything below IP44 has no place outdoors, full stop. British rain rarely falls vertically; wind-driven rain finds every gap, so treat the second digit as non-negotiable. For matching indoor and outdoor schemes, check the manufacturer's declared rating on the datasheet rather than the product photo — a rattan-look shade with an open top vent is not IP44 even if the lamp holder is. Illuminance targets for exterior installations, including recommended lux levels for porches and entrances, are published in the free SLL knowledge resources from CIBSE, and are well worth consulting before you finalise the layout.

Manufacturers have solved the rattan-outdoors problem with synthetic wicker. Polyethylene (PE) rattan and resin wicker replicate the woven texture of natural cane but are UV-stabilised, non-absorbent, and mould-resistant. They shrug off frost, hose down clean, and hold their colour — cheaper plastic copies yellow within a season, so check that the product specification explicitly states UV-stabilised PE or equivalent. Several outdoor-rated fittings pair this woven shell with a sealed IP44 or IP65 lamp compartment, giving you the aesthetic without the exposure problem. When you compare options, verify three things on the spec sheet: the IP rating, the material of the weave, and the rated operating temperature range (a proper outdoor fitting should handle -20°C to +40°C without the resin becoming brittle). Fittings such as the Terba range use a moulded, sealed construction rather than a decorative shade over an open lamp holder, which is why they carry a genuine IP44 rating. Choose a fitting whose entire body is rated, not just its electrical core.

Outdoor pendant installation follows the same mechanical principles as indoor work, with three additions. First, the fixing surface: mount the backplate to a solid, sealed surface — brick or block with a weatherproof gasket, not bare render or timber that will take up water. Second, the cable: use outdoor-rated flexible cable or conduit from the ceiling rose or isolation point, and make sure every gland and entry point is sealed with the supplied grommets; an open cable entry defeats the IP rating entirely. Third, the electrics: any new outdoor circuit or fixed fitting in Great Britain is notifiable work under Part P of the Building Regulations, so use a registered electrician. The Which? guide to hiring electricians explains how to check registration and get quotes properly. Finally, position the pendant so it hangs clear of door swings and head height — 2.1 metres minimum clearance below the lowest point is a sensible benchmark for a porch. Done correctly, an IP44 rattan-effect pendant needs nothing more than an occasional wipe-down.
