Zero II 36W LED Flush Ceiling Light 5000K - White

The Zero II is a 380mm circular flush ceiling light with an integrated 36W LED panel behind an opal white acrylic diffuser, set in a white metal surround. The LED runs at 5000K natural white with 2450 lumens output, producing the clear, daylight-balanced illumination typical of commercial and modern residential spaces where accurate colour rendering matters.

Designed for kitchens, bathrooms, home offices and hallways with ceiling heights of 2.2m or above, the Zero II addresses two practical needs: high light output for working spaces and a 55mm profile that suits low ceilings where semi-flush or pendant fittings would intrude. The 120-degree beam angle spreads light across a typical 3-4m room without creating sharp shadows or hotspots at the centre. The white metal surround pairs cleanly with white ceilings, reducing visual clutter overhead.

The opal acrylic diffuser softens the LED panel behind it while maintaining efficiency — the 2450lm output from 36W gives approximately 68 lumens per watt, on par with contemporary LED fittings. The 5000K colour temperature sits between the warm white typical of living spaces (2700K-3000K) and the cool white used in clinical settings (6000K+), making it suitable for areas where both visibility and comfort are needed: bathroom mirrors, kitchen worktops, desk surfaces. The fitting weighs 650g and mounts directly to a ceiling joist or mounting plate without a visible canopy gap.

The LED is non-dimmable and runs on standard UK 230V mains. Mantra includes a 3-year warranty covering the integrated LED and driver circuitry. The Zero II is part of Mantra's broader Zero collection, which includes smaller diameters and different colour temperatures for rooms needing matched fitting groups.

Is the Zero II dimmable?

No. The integrated LED runs at a fixed 36W output and is not compatible with dimmer switches. The output is constant at 2450 lumens.

What ceiling height does it need?

The 55mm projection suits ceilings from 2.2m upwards. For lower ceilings the fitting can still be installed but may feel visually closer overhead in rooms under 2.4m.

What size room does 2450 lumens cover?

The 2450lm output and 120-degree beam angle suit rooms of approximately 10-15m² for general lighting. In larger spaces or rooms requiring higher light levels, multiple fittings or additional task lighting may be needed.

How does 5000K natural white differ from warm white?

5000K sits in the daylight-balanced range, appearing crisp and neutral compared to the yellow-toned warmth of 2700K-3000K LEDs. It enhances visibility for detailed tasks but may feel clinical in living rooms or bedrooms where warmer light is preferred.
