Description

The Knot is a 480mm semi-flush ceiling light built from three continuous white loops that curve and cross over a central mounting plate. Each loop houses an integrated LED strip inside frosted white acrylic, with the three strips combining to deliver 2520 lumens at 4000K cool white from a total 36W power draw. The loops sit 190mm below the ceiling, creating a sculptural form that provides ambient light without requiring the clearance of a full pendant.

Designed for living rooms, kitchens, dining rooms and hallways with ceiling heights of 2.4m or above, the Knot suits modern and contemporary interiors where functional brightness is needed alongside a decorative ceiling feature. The 4000K colour temperature produces a clean, neutral-white light similar to daylight office lighting, making the fitting more suited to task-oriented spaces and modern schemes than warm-toned traditional interiors. The 120° beam angle spreads light broadly across the room rather than creating directional pools.

The white finish on both the loops and the ceiling plate gives the fitting a cohesive monochrome appearance that recedes visually in white-ceilinged rooms while maintaining sculptural presence through the looping form itself. The frosted acrylic diffuses the LED strips evenly, avoiding visible LED dots or hotspots. At 1.2kg the fitting mounts to a standard UK ceiling rose and requires no additional joist support. The LEDs are non-dimmable and non-replaceable — when they reach end of life the entire fitting is replaced.

Frequently Asked

Is the Knot dimmable?

No. The integrated LEDs are non-dimmable and operate at full 2520lm output when switched on. They cannot be controlled by dimmer switches.

What ceiling height is needed?

The fitting projects 190mm below the ceiling. In rooms with 2.4m ceiling height this leaves approximately 2.2m clearance, which is adequate for most residential spaces. Lower ceilings may find the fitting intrusive in circulation areas.

Can the LEDs be replaced?

No. The LEDs are integrated into the acrylic loops and are not user-replaceable. When the LEDs reach end of life the entire fitting is replaced. Mantra typically rates integrated LED lifespan at 25,000-30,000 hours.

What light colour is 4000K?

4000K is a cool white, neutral daylight tone similar to office or retail lighting. It sits between the warm amber glow of 2700K-3000K domestic lighting and the clinical brightness of 5000K+ hospital lighting. It pairs well with modern grey and white interiors but can feel clinical in traditionally decorated rooms.
