SU Series
The SU series draws on the steelyard, China’s earliest balance, under utility model patent ZL202321681200.9 and the 2023 Red Cotton Design Award. Head beams adjust from 24° to 55°, and lengths and drops are customisable.
Most pendant spotlights are locked to a fixed point with limited adjustment, which caps what lighting can do in a room. The SU series draws on the steelyard — China’s earliest balance, one rod and one weight, an emblem of fairness and openness. The design strips everything back to a straight rod, then pairs that line with a source that moves freely.
SU-Chan: lighting and water in one
Built around the tea-room brief: lighting, water and ornament in one object. A contactless spout is safer and more hygienic, paired with deep anti-glare spots for a relaxed ambience.
SU-Heng: a horizontal external track
A safe low-voltage track carries deep anti-glare heads with lens and honeycomb stacks. Heads glide left and right and rotate through 360°. For studies and bedrooms; length is customisable.
SU-Yuan: a removable, aimable head
A removable head on a track-adjustable pole, rotating through 360° horizontally for precise aim.
SU-Pan: soft area light above and below
A circular acrylic guide emits above and below — soft, glare-free fill for large or small rooms.
SU-Jian: a narrow-beam floor accent
A very narrow beam gives focused floor-level accent lighting; the pole tilts 25° and the head rotates 360°.
SU-Yin: a water-and-light pole you can resize
The hollow pole carries a purified-water line, swings 25° horizontally, and opens by touch. It can be extended or shortened to suit the room.

Optics and warranty
| Item | Value | Notes |
|---|---|---|
| Beam angle | 24°–55° via knurled head rotation | The knurled head rotates to focus; fixed 15°, 24° and 36° sources are also available. |
| Colour rendering | CRI ≥95, SDCM ≤2 | SUFN monochromatic light, the standard figure across the range. |
| Glare | Deep anti-glare heads with lens and honeycomb stacks | On SU-Heng the safe low-voltage track works with stacked anti-glare optics so the source stays hidden. |
| Material | Minimal metal rods, acrylic guides and circular acrylic light guides | SU-Pan uses a circular acrylic guide to light above and below. |
| Customisation | Lengths and drops customisable | Size, form, smart functions and combination patterns can be specified per project. |
| Power & safety | Safe low-voltage track | Low voltage raises the safety margin, which matters in studies, bedrooms and tea rooms where people linger. |
| Warranty | Source and driver 5 years, body 3 years | Residential interiors only; project, hotel and club work is uniformly three years. |
Frequently asked questions
QHow does the SU series differ from an ordinary pendant spot?
Ordinary pendant spots are locked to a fixed point. The SU series pairs a minimal linear form with freely adjustable sources: SU-Heng heads glide along the track and rotate through 360°, SU-Yuan pendant heads move vertically, and the modular heads take removable sources.
QCan the SU-Heng track be custom-sized?
Yes. SU-series lengths and drops are customisable, and the SU-Heng track is ordered to the measured span. Measure the clear wall width and leave about 150 mm of fixing margin at each end.
QWhere does SU-Chan belong?
SU-Chan merges lighting, water and ornament. The contactless spout is safer and more hygienic, which suits tea rooms, tea tables and wet bars; the deep anti-glare spots provide relaxed ambient light.
QCan SU-series fixtures join the smart system?
Yes. The safe low-voltage supply lets SU fixtures join SUFN OS circuits for dimming and scenes at 0.01% depth. The connection must match the driver, so tell us the driver in the enquiry form below.
