Coin Large Square CCT LED Flush Ceiling Light With Remote Control - White

The Coin Large Square is a 540mm flush ceiling light with an integrated 100W tuneable LED, delivering 4900 lumens through a white-framed square panel. The fitting comprises an outer white frame enclosing a recessed inner square, creating a two-tier profile 70mm deep that sits close to the ceiling surface. The central luminous panel spans most of the 540mm width, producing even illumination across its full width with a 120° beam angle.

Designed for living rooms, bedrooms and open-plan spaces where overhead lighting needs to serve multiple functions throughout the day, the Coin's tuneable CCT allows adjustment between 2700K warm white and 5000K daylight white via the included remote control. The remote also provides stepless dimming across the full brightness range, giving control over both colour temperature and intensity without requiring wall switches or app connectivity. The 4900lm output suits rooms up to approximately 20-25m² at full brightness.

The white finish on the frame is a smooth matte coating that diffuses ceiling reflections and keeps the focus on the illuminated panel rather than the fitting hardware. The recessed inner square adds visual depth without breaking the flush profile, while the rounded corners soften the geometry slightly compared to a hard-edged square. At 2.8kg the fitting requires secure ceiling fixings capable of supporting that weight long-term, particularly on plasterboard ceilings where spreader plates or cavity fixings are recommended.

The 70mm projection makes the Coin suitable for rooms with ceiling heights of 2.4m or above, where a low-profile fitting is preferred over a suspended pendant. The CCT tuning function allows the light to shift from warm relaxed tones for evening use to cooler task-oriented light during the day, replacing the need for separate fittings or layered lighting schemes in single-purpose rooms.

How is the colour temperature adjusted?

The Coin includes a remote control that adjusts the CCT between 2700K warm white and 5000K daylight white in a continuous range. The same remote provides stepless dimming from 1-100% brightness. No wall dimmer or smartphone app is required.

What room size does the 4900lm output suit?

At full brightness the 4900lm output suits living rooms, bedrooms and open-plan spaces up to approximately 20-25m². Larger rooms may benefit from two Coin fittings spaced across the ceiling, or pairing with supplementary task lighting.

Is the LED replaceable?

No. The LED array is integrated into the fitting and is not user-replaceable. The LED is rated for approximately 25,000-30,000 hours of use, equivalent to around 10-15 years of typical domestic operation before noticeable brightness degradation.

What ceiling height is recommended?

The 70mm projection and 540mm square footprint work best in rooms with ceiling heights of 2.4m or above. In lower ceilings the fitting may feel visually dominant due to its width, though the flush profile minimises the projection into the room.
