Helvar amplitude dimming* DALI-2 controllable LED drivers offer the best available technology for dimming the light output in an accurate and flicker-free way. Amplitude dimming implements technique for adjusting the DC supply for the LED modules stably all the way down to 1 %. This means visually flawless light output that does not pose any risk to human eyesight or camera recording applications, and naturally complying with e.g. IEEE 1789-2015 standard about minimizing flicker. Amplitude dimming ensures constant light levels in all situations and lighting environments.
