Slim 460mm LED Flush Ceiling Light 50W 3000K - White

The Mantra Slim is a 460mm diameter flush-mounted LED ceiling light with an integrated 50W 3000K LED delivering 4150 lumens through a white acrylic diffuser. The fitting sits just 66mm from the ceiling, making it suitable for rooms with ceiling heights below 2.4m where a pendant or semi-flush would feel too low.

Designed for living rooms, bedrooms, home offices and hallways needing general ambient light without fixtures that project into headroom, the Slim distributes 4150 lumens across a 140° beam angle. This wide spread reduces harsh shadows and provides consistent coverage across rooms up to approximately 20 square metres. The 3000K warm white colour temperature sits in the relaxed end of the spectrum, closer to traditional tungsten bulbs than cooler daylight LEDs.

The white finish on the diffuser and trim gives a clean, neutral appearance that blends with white or off-white ceilings in contemporary and minimalist interiors. The acrylic diffuser softens the LED point sources behind it, preventing visible individual diodes and producing a uniform glow across the disc. At 0.92kg the fitting installs directly onto a standard ceiling rose without needing additional support.

The non-dimmable driver runs on 220-240V mains with a fixed 50W draw, equivalent to approximately 250-300W from a traditional tungsten ceiling fitting at similar lumen output. The 66mm profile leaves more vertical space than bulkier fittings while still housing the full LED array and driver within the ceiling-mounted body.

Is the Slim dimmable?

No. The integrated LED driver is non-dimmable. Connecting it to a dimmer switch may cause flickering or damage to the driver.

What room size does 4150 lumens cover?

4150 lumens with a 140° beam spread suits rooms up to approximately 20 square metres as primary ambient lighting. For larger spaces or rooms needing brighter task lighting, consider pairing with additional fittings or using a higher-output model.

What ceiling height is needed?

The 66mm projection from the ceiling makes the Slim suitable for standard UK residential ceiling heights of 2.3-2.4m and above. It works particularly well in rooms with lower ceilings where pendant lights would encroach on headroom.

How is the diffuser cleaned?

Switch off at the mains before cleaning. Wipe the acrylic diffuser with a dry microfibre cloth. For stubborn marks, use a barely-damp cloth with water only — avoid household sprays, polish or solvents, which can discolour or craze acrylic.
