visDIM PRO 30 is our new 'media friendly' 30kHz PWM frequency DALI-2 dimming sub-controller designed to eliminate unwanted flickering effects that can potentially be picked up in some video recording devices and be noticeable in video playback. Compatible with a wide selection of KKDC LED strips, please look out for the new visDIM PRO green tick icon throughout our product specs and speak to your local KKDC branch for more information.
