We’ve moved past analog! an·a·log 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!
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 -10 v? • A varied input from 0 to 10 v • One way communication • The scale for 0 -10 v values are set by the individual manufactures.
What is 0 -10 v? • A varied input from 0 to 10 v • One way communication • The scale for 0 -10 v 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 -10 v 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 1. Early DALI Systems were a nightmare to commission!

HCL with 0 -10 v scale set by the manufacturer
Human Centric Lighting (HCL) DALI vs. 0 -10 v DALI 0 -10 v • Exact color temperature no matter how long the wire runs. • Color temperature changes with long wiring runs
Human Centric Lighting (HCL) DALI vs. 0 -10 v DALI 0 -10 v • Exact color temperature no matter how long the wire runs. • Exact color temperature on fixtures from different manufacturers • Color temperature changes with long wiring runs • The same command sent to fixtures from different manufactures will produce different color temperatures.
