What is the difference between a DALI and a 0-10V dimming control system?

  1. They are identical systems with different names
  2. DALI is a digital protocol allowing individual addressing and bidirectional communication; 0-10V is an analog signal providing simple one-directional dimming
  3. 0-10V is more expensive and complex than DALI
  4. DALI can only dim to 50% while 0-10V can dim to 0%

Answer: B — DALI is a digital protocol allowing individual addressing and bidirectional communication; 0-10V is an analog signal providing simple one-directional dimming
