Mantra Niseko II 42cm Triangular Ceiling Light - Black

Same Idea, Different Shape

Niseko II usually shows up as a circle, so the 42cm triangular version stands out simply by breaking that pattern. The outline is a softly rounded triangle rather than a sharp geometric one, which keeps the fitting feeling calm and considered instead of gimmicky.

Black, With An Edge

Finished in black, this version pairs the unusual silhouette with a colour that keeps things grounded rather than showy, so the shape gets noticed before the finish does. It suits rooms that already lean towards clean, contemporary lines, where a plain circular fitting might feel like the safe option rather than the right one. The Niseko II triangular shape is also available in white, gold and a wood effect finish and in a larger size, so the look can be scaled up or coordinated with the round versions elsewhere in a home.

How It Works

A single 38W LED is built into the fitting and diffused through the black band, producing 2500 lumens across a 145 degree beam angle with a CRI above 80. The remote control supplied with the light lets you tune the colour temperature anywhere from 2700K to 5000K, moving from a warm glow to a cooler white without needing to change any bulbs. Brightness and colour temperature are both set through the fitting's own driver, so it is not intended to be run through a separate wall dimmer.

Where It Works Best

Measuring 42.1cm along each side, this is a compact fitting that suits bedrooms, hallways or as a secondary light in a living or dining room, similar in scale to the 38cm round version but with a shape that reads quite differently on the ceiling. It is worth using where the ceiling itself is a feature, since the triangular outline is more visible from below than a plain ring would be.

Made By Mantra

Mantra has been designing lighting in Valencia since 2000, building a catalogue that now covers decorative, technical, outdoor and ventilation products while staying rooted in that original idea of design led lighting at sensible prices. The brand's design credentials were recognised externally in 2024, when Nacho Timon's modular track fan won Gold at the regional ADCV design awards, built with components designed for separate recycling and some recycled or sustainably sourced materials. That same design team is behind the more experimental shapes in the current range, including this triangular take on a normally circular fitting.

Questions People Ask

Is this a sharp cornered triangle or a softer shape?
It is a softly rounded triangular outline rather than a sharp geometric one, so the corners are curved rather than pointed.

Can the colour temperature be adjusted without an app?
Yes. The light is tuned between 2700K and 5000K using the remote control supplied with the fitting, so no app or extra hardware is required to use it.

Can this be controlled with a wall mounted dimmer switch?
No. Dimming and colour temperature are both handled by the fitting's own remote and driver, so it should be wired to a standard switched supply instead.
