Indoor lighting
The base layer sets illuminance, pool definition and glare. SUFN indoor lighting is built on dual-channel convective cooling, custom anti-glare lenses and SUFN monochromatic light: CRI above 95, SDCM at or below 2, dimming to 0.01%.
Indoor lighting is the base layer of any trackless-lighting scheme. It sets the illuminance level, the edge definition of every light pool and the glare control — the first layer to be specified and the hardest to change later. SUFN indoor lighting is built on dual-channel convective cooling, custom anti-glare lenses and SUFN monochromatic light, and covers downlights, magnetic track, linear tape and drivers as a complete chain.
Three hard numbers behind SUFN indoor lighting
CRI above 95, SDCM at or below 2
SUFN monochromatic light is tuned to Asian skin tones and perception. High CRI renders true material colour; the tight SDCM keeps every fixture in one room visually matched.
Dual anti-glare, UGR ≤6, cut-off above 45°
A custom SUFN anti-glare lens with cross-distribution raises useful output and cuts spill. The black-glare design gives a cut-off angle above 45° — light you see, sources you do not.
0.01% dimming depth, consistent across 100+ fixtures
Very fine light control for slow, silk-smooth fades. Even with more than a hundred fixtures in one zone, dimming level and colour stay in step.

Ruizhi II and MINI Cube are the two series in focus here; for the other series, see the matching page in the official product catalogue.
Ruizhi II DownlightThe baseline downlight where glare and colour rendering both matter: UGR ≤6, cut-off above 45°, CRI ≥98, with about 15% better cooling and 30% more light on target.
MINI CubeFor positions where a small body and high fidelity must coexist: CRI ≥98 in a single die-cast body, twelve variants, recessed or pre-embedded.

Drivers and dimming protocols
| Protocol / method | Where it fits | Notes |
|---|---|---|
| DALI | Whole-house, hotel and club projects | Constant-current, addressable per circuit with status read-back for commissioning and diagnosis. |
| 0–10V | Multi-circuit zoned dimming | Interfaces with mainstream building-control and third-party dimming systems. |
| Phase-cut | Retrofit onto existing wiring | Works with standard household wiring, including neutral-wire installation, with no rewiring. |
| Smart dimming and tuning (SUFN OS) | Whole-home scenes, zoning and linking | 0.01% dimming depth, executed locally across gateways, still linked when a gateway is offline. |
| Constant-voltage / constant-current controllers | Tape and bespoke sources | A serial protocol gateway is also available for third-party devices. |
