Cumbuco II 500mm Round CCT LED Flush Ceiling Light 40W - Black

The Cumbuco II is a 500mm diameter flush ceiling light with an integrated 40W CCT LED behind an acrylic diffuser, framed by a 68mm-high black metal housing. The CCT function allows switching between three colour temperatures (2700K extra warm white, 3300K warm white, 4000K cool white) using the wall switch, with no remote or app required — cycle through the temperatures by switching the light off and on again within two seconds.

Designed for rooms with ceiling heights below 2.4m where a pendant or semi-flush would hang too low, the 68mm profile keeps the fitting tight to the ceiling while the 500mm diameter provides enough coverage for bedrooms, hallways, home offices and bathrooms up to 12-14m². The 2800 lumen output at 40W input gives general ambient lighting rather than task-focused brightness, and the 145° beam angle spreads light wide across the ceiling plane to reduce shadows in the corners.

The black frame sits flush against the ceiling rose, concealing the fixings and cable entry point behind a clean circular perimeter. The acrylic diffuser prevents glare from the LED array inside while maintaining even light distribution across the full 500mm face. The non-dimmable driver is built into the housing, so no external transformer or control gear is needed — wire directly to the mains ceiling supply and the CCT switching function is active immediately.

The black finish contrasts with white or light-coloured ceilings to give the fitting a defined visual presence rather than blending in. Combined with the ability to switch colour temperature on demand, the Cumbuco II suits spaces where lighting needs change between morning (cooler white for focus) and evening (warmer white for relaxation) without needing multiple fittings or complex control systems.

How does the CCT colour temperature switching work?

The CCT function cycles through three colour temperatures (2700K extra warm, 3300K warm, 4000K cool white) using the wall switch. Turn the light off and back on within two seconds to advance to the next colour temperature. No remote or app is required — the driver remembers the last setting when you turn the light off normally.

What room size does the 500mm diameter suit?

The 500mm diameter with 2800 lumens output provides general ambient lighting for rooms up to 12-14m². This works well for bedrooms, home offices, hallways and bathrooms. Larger living spaces may need multiple fittings or a larger diameter flush light for adequate coverage.

Is it suitable for low ceilings?

Yes. The 68mm height makes this flush light suitable for ceilings below 2.4m where pendant lights would hang too low. The fitting mounts directly to the ceiling rose with minimal projection into the room.

Can it be dimmed?

No. The integrated LED driver is non-dimmable. Installing a dimmer switch will not dim the light and may cause flickering or damage to the driver. The CCT switching function provides three fixed brightness levels at different colour temperatures, but this is not the same as dimming.
