Niseko Triangular CCT Dimmable LED Flush Ceiling Light With Remote Control 38W - White

The Niseko is a 421mm triangular flush ceiling light with an integrated 38W LED that delivers 2500 lumens through a white metal frame. The LED runs along the inner edge of the triangular form, creating a continuous band of light that appears to float within the geometric outline. Colour temperature is tuneable between 2700K warm white and 5000K daylight white using the supplied remote control, which also handles dimming across the full output range.

Designed for bedrooms, hallways, kitchens and living spaces with standard 2.4m ceiling heights, the 63mm profile sits close to the ceiling without dominating the room visually. The remote allows instant adjustment from warm ambient lighting in the evening to brighter neutral-white task light during the day, removing the need for multiple fittings or manual switching. The 145° beam angle provides even coverage across typical 12-16m² rooms without creating harsh shadows or hotspots.

The white powder-coated metal frame pairs cleanly with neutral palettes, pale woods and Scandinavian-style interiors. At 1.7kg the fitting mounts securely to standard UK ceiling joists or ceiling roses and connects to mains 220-240V supply without requiring external drivers or transformers. The triangular geometry breaks away from circular and square ceiling light conventions, adding a subtle architectural detail to rooms where decorative pendant lights would hang too low or feel visually heavy.

The Niseko is part of Mantra's range of geometric LED flush fittings and carries a three-year manufacturer warranty covering the integrated LED and remote control circuitry.

How is the colour temperature adjusted?

The supplied remote control provides buttons for both dimming and CCT adjustment. The tuneable range spans 2700K warm white through to 5000K daylight white, allowing gradual shifts or immediate jumps between temperatures. The remote operates via RF signal and does not require line-of-sight to the fitting.

What room size does the 2500lm output suit?

At full brightness the Niseko provides sufficient ambient light for rooms between 12-16m² (roughly 3.5m x 4.5m or equivalent). Smaller rooms can use the dimming function to reduce output, while larger open-plan spaces may benefit from pairing two Niseko fittings or supplementing with task lighting.

Is the LED replaceable?

The LED is integrated into the fitting and is not user-replaceable. Mantra rates the LED module for 25,000+ hours of operation, which equates to approximately 11 years of typical domestic use at 6 hours per day. The three-year warranty covers the LED and control circuitry.

What ceiling height is required?

The 63mm profile makes the Niseko suitable for low ceilings from 2.2m upwards. The flush mount sits tight to the ceiling, so there are no minimum height restrictions beyond standard habitable room requirements.
