DALI vs 0-10V dimming comparison: bidirectional vs unidirectional, addressable vs group-only, wiring topology, maximum f…
| 对比维度 | 选项A | 选项B | 优胜 |
|---|---|---|---|
| Communication | Bidirectional (send + receive status) | Unidirectional (send only) | DALI (feedback) |
| Addressability | Individual fixture (64 per bus) | Group only (all on wire) | DALI (per-fixture) |
| Dimming Range | 0.1% — 100% | 10% — 100% (1% with special driver) | DALI (wider range) |
| Wiring | 2-wire bus (polarity-free), max 300m | 2-wire + 0-10V pair (polarized), max 100m | DALI (simpler wiring) |
| Cost Premium | +25-40% vs non-dimming | +10-20% vs non-dimming | 0-10V (cheaper) |
| Scene Control | 16 scenes, 16 groups per fixture | External controller required | DALI (built-in) |
| Energy Monitoring | Built-in power monitoring | Not supported | DALI |
| Best For | Large commercial, smart buildings | Simple dimming, small offices | — |
0-10V适用简单低成本项目：小办公室、零售、基础调光需求。DALI适用智能建筑、大型商业空间及需要单灯控制/能耗监测/场景管理的项目。DALI-2增加跨厂商互操作性。Compare2Best多数灯具两种协议可选——下单时指定。
