DALI vs 0-10V Dimming Comparison
Lighting control protocol comparison.
0-10V is analogue: one control pair per group, no addressing and no feedback. DALI is a digital bus: every driver carries an address and can report lamp failure, burn hours and dimming level back to the controller.
| Comparison | Option A | Option B | Winner |
|---|---|---|---|
| Addressing | Individual | Group | DALI |
| Reverse feedback | Yes | No | DALI |
| Cost | Higher | Lower | 0-10V |
| Best for | Large projects | Simple retrofit | Application-dependent |
Conclusion
Use 0-10V for straightforward dimming in warehouses, car parks and retrofit projects where one group is enough. Use DALI when the building needs per-fixture addressing, fault reporting or BMS integration — the extra cost per driver buys diagnostics and control granularity.
