DALI on the spec, deaf on site. Why there's no such thing as a "DALI strip"

The lighting schedule says "DALI LED strip". On site, the evening scene won't recall, the run doesn't take its address, and the commissioning engineer is looking for a DALI device that was never ordered.

Where DALI actually lives

An LED strip is a load. It receives power and turns it into light. It doesn't speak DALI, 0/1–10 V or any other control protocol by itself.

In a DALI system, the part that speaks DALI is the driver or interface that powers the strip. That device has the DALI address, receives commands from the bus and dims the strip. Choose the right gear and the strip dims smoothly under DALI. Leave it out, and no strip on the drawing will respond.

As our technology page puts it: DALI, 0/1–10 V and phase-cut control require a compatible driver or interface. For tunable white over DALI, specify suitable DT8(Tc) gear. The strip itself does not make a system DALI certified.

Why the confusion happens

• Shorthand on schedules. "DALI strip" is quicker to write than "constant-voltage strip on a DALI driver".
• Kits and bundles. A strip sold with a DALI driver can be called a "DALI strip" in one catalogue and simply an "LED strip" in another.
• Tunable white. Adjusting colour temperature over DALI needs gear that supports it (DT8 Tc), not just any DALI dimmer.

What helps

1. Specify the gear, not just the strip. Write the protocol, the driver or interface model and the device type on the schedule.
2. For tunable white over DALI, name DT8(Tc). Otherwise the run may dim but not change colour temperature.
3. Match voltage and load. The driver's output voltage and capacity must suit the strip model and the total watts of each run.
4. Plan addressing and commissioning. Our technology page lists what a commissioning brief should record: zones, pixel count, dimming range, scene behaviour, power-feed locations and signal runs.
5. Decide who owns the control schedule. The designer, the electrical contractor or the integrator: one party should hold it, and check it against the gear actually ordered.

The same applies to other protocols

0/1–10 V and phase-cut dimming also depend on a compatible driver. DMX and SPI depend on decoders and controllers. In every case, specify the complete signal path alongside the power path.

If you're writing a schedule for a controlled strip system, send us the protocol and the zones. We can help match the strip to the right controllers and decoders.
