Niseko Triangular LED Flush Ceiling Light 50W CCT Dimmable Remote - Light Brown

The Niseko is a 611mm triangular flush ceiling light with an integrated 50W LED panel and a light brown wood-effect finish. The triangular frame has softly rounded corners and sits 63mm from the ceiling, with the LED strip mounted along the inner edge to cast light both downwards through the centre diffuser and outwards as a halo around the perimeter. The result is 3000 lumens of output distributed across a 145-degree beam angle, giving even coverage across 12-18m² rooms.

Designed for living rooms, bedrooms, home offices and dining areas where a central ceiling fitting provides the main ambient light, the Niseko combines functional output with a geometric form that reads as a design feature rather than just a light fitting. The included remote control adjusts both brightness (0-100% dimming) and colour temperature between 2700K warm white and 5000K cool white, allowing the light to shift from relaxed evening ambience to task-focused daytime brightness without changing bulbs or rewiring.

The light brown finish is a printed wood-effect vinyl wrap over a metal base, giving the visual warmth of timber without the weight or maintenance requirements of solid wood. The triangular footprint measures 611mm point-to-point, which suits ceilings in rooms between 3m x 3m and 4.5m x 4.5m where a circular fitting of equivalent size (550-650mm diameter) would feel too predictable. The 63mm projection keeps the fitting tight to the ceiling, making it suitable for standard 2.4m ceiling heights without reducing headroom.

The Niseko uses edge-lit LED technology where the light source sits in a narrow channel around the triangle's perimeter and diffuses through an acrylic panel in the centre. This produces soft, flicker-free illumination without visible LED dots or hotspots. The remote control operates on RF (radio frequency) rather than infrared, so it works without line-of-sight and can be used from adjacent rooms or through furniture.

Is the LED replaceable?

No. The LED is integrated into the fitting and rated for approximately 25,000 hours of use (around 11 years at 6 hours per day). The entire fitting would need replacing if the LED fails, though Mantra provides a 3-year warranty.

What room size does it suit?

The 3000 lumen output and 145-degree beam angle suit rooms between 12-18m², which equates to living rooms or bedrooms of roughly 3m x 4m to 4.5m x 4.5m. In larger rooms the Niseko works well as accent lighting or paired with additional fixtures.

How is the colour temperature adjusted?

The included RF remote control has dedicated buttons for warm white (2700K), neutral white (4000K), and cool white (5000K), plus a slider for intermediate temperatures across the 2700-5000K range. The remote does not require line-of-sight to the fitting.

Can it be installed on a sloped ceiling?

The Niseko is designed for flat horizontal ceilings. Installation on a sloped ceiling would require custom mounting and is not recommended by the manufacturer.
