Cumbuco II 650mm Round CCT LED Flush Ceiling Light 50W - White

The Cumbuco II is a 650mm diameter flush ceiling light with an integrated 50W LED panel behind an acrylic diffuser, set within a white circular frame that projects 70mm from the ceiling. The CCT function allows the LED to switch between 2700K extra warm white, 3300K warm white, and 4000K cool white without changing the bulb, controlled by cycling the wall switch on and off.

Designed for rooms with low ceilings or where a pendant would intrude into headroom, the Cumbuco II delivers 3200lm across a 145° beam angle, making it suitable for bedrooms, hallways, bathrooms (check IP rating for zone compliance), kitchens and open-plan living areas up to approximately 16-20m². The white frame conceals the LED driver and wiring within a shallow housing that fits flush to the ceiling rose.

The 650mm diameter gives the fitting substantial presence without requiring significant ceiling height, while the 70mm profile keeps the fixture close to the ceiling plane. The acrylic diffuser spreads light evenly across the room without visible hotspots or LED dot patterns. The white powder-coated metal frame pairs with modern, Scandi and minimalist interiors, and the selectable colour temperature allows the same fitting to be tuned to different rooms or changed seasonally.

The fitting weighs 2.75kg, requiring secure fixing to a ceiling joist or spreader bar rather than just plasterboard alone. Installation follows standard UK ceiling light wiring with a separate driver unit housed inside the frame. The LED is integrated and non-replaceable, with the entire unit carrying a 3-year warranty from Mantra.

How does the CCT colour temperature switching work?

The CCT function cycles between 2700K, 3300K and 4000K each time you turn the light off and back on at the wall switch within a few seconds. The fitting remembers the last setting when left off for longer periods. This allows you to choose warmer light for evenings or cooler light for task-focused daytime use without replacing the bulb or installing a control unit.

Is this suitable for low ceilings?

Yes. The 70mm projection from the ceiling makes the Cumbuco II well-suited to rooms with ceiling heights of 2.3m or lower, where pendant lights would reduce headroom. The flush mount design keeps the fitting close to the ceiling plane while still delivering substantial light output.

What size room does the 3200lm output suit?

The 3200lm output from a 145° beam angle typically provides general ambient lighting for rooms up to 16-20m² (a 4m x 5m bedroom or lounge). Larger open-plan spaces may need multiple fittings or supplementary task lighting in specific zones.

Can it be dimmed?

No. The integrated LED is not dimmable. The light level is fixed at 3200lm, but the CCT function allows you to adjust the warmth of the light, which can make the output feel less intense in the evening when switched to 2700K.
