I have tried both with Lutron Grafik Eye and Lutron Grafik Integrale. Both have the same issue. I got a fluorescent tube (1) with built in electronic ballasts. The problem is, that when this fluorescent light is set to "0" (off) in a zone, the light flickers slightly. When the light is turned on, there is no flicker, also when the Lutron is turned off via "ALL OFF" button there is no flicker. I have set the light as "NON DIM, FIRST ON FIRST OFF" Any ideas? Might the reason be that the load is too low? (1light), or the light is not suitable?
