We’ve moved past analog! ˈanlˌôɡ/ adjective 1. relating to or using signals or information represented by a continuously variable physical quantity such as spatial position or voltage.

We are in the age and we’ve moved past analog in almost every way…….

Except for Dimming!!!!

Why are we still controlling solid state lighting with an analog signal?

It’s like designing a Printed Circuit Board

On a Drafting Table!!

It’s time to move dimming to Digital!

It’s time to move dimming to Digital! And Digital in Lighting is

It’s time to move dimming to Digital! And Digital in Lighting is DALI

It’s time to move dimming to Digital! And Digital in Lighting is DALI

What is DALI? DALI = Digital Addressable Lighting Interface It is a communication standard designed specifically for lighting.

What is DALI? DALI defines how each component in a lighting control system communicates. True 2-Way Communication!

DALI is also an “Open” standard. Why is that important? What is DALI? DALI is also an “Open” standard. Why is that important?

What is DALI? As an open standard any manufacturer can create devices that communicate using DALI.

What is DALI? For example a DALI driver from one manufacturer will work with control stations, sensors, etc. from any other manufacturer using DALI.

What is DALI? Levels the playing field End user creates the exact system for their needs OEM’s have to become more innovative with their products More focus on design and customer service

What is 0-10v? A varied input from 0 to 10v One way communication The scale for 0-10v values are set by the individual manufactures.

So why isn’t it used more in the United States?

So why isn’t it used more in the United States? The Drivers are more expensive than 0-10v Drivers

$4 to $6 premium on DALI Drivers Harvard Technology $4 to $6 premium on DALI Drivers

So why isn’t it used more in the United States? Installers don’t have experience with DALI

Lutron Eco System

Lutron Eco System Is DALI!!

Lutron Eco System Or rather based on DALI. It has been modified to be proprietary, but still retains all of the functionality of DALI.

The real reason’s its not used more

The real reason’s its not used more Early DALI Systems were a nightmare to commission!

Exact color temperature on fixtures from different manufacturers 0-10v Color temperature changes with long wiring runs The same command sent to fixtures from different manufactures will produce different color temperatures.
