01 / The feeling
Sculptural Simplicity, Beautifully Lit
The Riba brings effortless modern style to any room with its clean, sculptural form. The dome-shaped shade, detailed with fine vertical ribs, creates soft shadows and gentle texture across your ceiling whilst casting warm, inviting light below. Its bright white finish complements everything from contemporary kitchens to minimalist bedrooms, adding a touch of Scandi-inspired charm without overwhelming your space.
With its low-profile design, this 40 cm ceiling light sits sleekly against the ceiling—perfect for rooms where height is precious. The single E27 lampholder gives you complete control over brightness and ambience (bulb not included), and it's fully dimmable with a trailing edge dimmer and compatible bulb. Rated IP20 for indoor use, it combines quality plastic construction with practical, everyday reliability. Class I earthed fitting for your peace of mind.

Good to know
A few questions,
before it comes home.
Does the Riba ceiling light require an electrician to install?
Yes, the Riba is hardwired and must be installed by a qualified electrician in compliance with UK Building Regulations Part P. The installation involves connecting mains wiring directly to the fitting, which is notifiable electrical work. Most electricians will find it a moderate difficulty job, and the fitting is suitable for mounting on plasterboard, timber joists, or concrete ceilings.
What type of bulb does the Riba 40cm ceiling light take?
The Riba uses a standard E27 screw-in bulb (also called an Edison Screw), with a maximum wattage of 7W. The bulb is not included, so you'll need to purchase one separately. For best results with the ribbed shade design, choose an E27 LED bulb with a warm white colour temperature (2700K-3000K).
Can the Riba white ceiling light be dimmed?
Yes, the Riba is dimmable when fitted with a compatible dimmable E27 bulb. You'll need to install a trailing edge dimmer switch to control the brightness smoothly without flickering. Both the dimmer and the dimmable bulb must be purchased separately, as neither is included with the fitting.
Is the Riba ceiling light suitable for a bathroom?
No, the Riba has an IP20 rating, which means it's not protected against moisture and is only suitable for dry indoor locations. It cannot be used in bathrooms or any areas where it may be exposed to water or high humidity. For bathrooms, you'll need a fitting with a minimum IP44 rating (or IP65 for shower zones).
What are the dimensions of the 40cm Riba ceiling light?
The Riba measures 40cm (400mm) in width and 32.5cm (325mm) in total height from ceiling to the bottom of the shade. This makes it well-suited for standard ceiling heights in bedrooms, hallways, or smaller living spaces where you need a compact yet sculptural ceiling light that won't hang too low.
What warranty does the Riba ceiling light come with?
The Riba is covered by a 2-year manufacturer's warranty against defects in materials and workmanship. The fitting is CE marked and RoHS compliant, meeting UK safety standards. Note that the warranty covers the light fitting itself; bulbs are consumable items and are not covered.
