Twilight White LED Flush Ceiling Light 18W 4000K - 90cm

The Twilight is a 90cm diameter flush LED ceiling light with an integrated 18W LED rated at 4000K, housed in a white powder-coated aluminium body that sits 25mm from the ceiling. The light is built around two concentric rings — an outer diffuser ring and an inner recessed disc with a central mounting recess — both casting light downwards and outwards across the ceiling surface to reduce harsh shadows in large rooms.

Designed for open-plan living rooms, large kitchens, dining areas and commercial spaces with ceiling heights between 2.4m and 3.2m, the 90cm diameter provides wide light distribution without needing multiple ceiling fittings. The 25mm projection makes it suitable for low ceilings where a pendant or semi-flush fitting would hang too far into the room. The 4000K colour temperature provides neutral white light closer to daylight than warm white, making it suited to task-focused areas like kitchens, home offices and utility rooms rather than relaxation spaces.

The white powder-coated aluminium construction resists yellowing under UV exposure better than plastic equivalents and dissipates the LED heat efficiently enough to maintain the 18W output over the rated lifespan. The IP20 rating limits this fitting to dry indoor locations — it is not suitable for bathrooms, covered outdoor areas or anywhere moisture is present. The non-dimmable LED is fixed at full output when switched on, so pairing with a smart switch or timer provides the only control option.

Is the Twilight dimmable?

No. The integrated LED is non-dimmable and operates at full 18W output when switched on. If dimming control is needed, a smart switch or smart bulb alternative would be required instead.

What size room does the 90cm diameter suit?

The 90cm diameter and 18W output suit rooms between 15m² and 25m² — typical open-plan kitchens, large living rooms or dining areas. Smaller rooms may find the 90cm diameter visually dominant, while larger spaces may need a second fitting or supplementary lighting.

Can it be used in a bathroom?

No. The IP20 rating means it is not protected against moisture and must only be installed in dry indoor locations. Bathrooms require a minimum IP44 rating for ceiling zones.

What does 4000K colour temperature look like?

4000K is neutral white — cooler than the warm whites (2700K-3000K) typically used in living rooms and bedrooms, but not as stark as the daylight whites (5000K-6500K) used in clinical or industrial settings. It suits task-focused areas like kitchens, home offices and utility rooms.
