So arc fault breakers weren't tripping prior to LED drivers? I believe the UL listing on arc fault breakers state they need to support at least 1000 watts of dimmed tungsten lighting load. Tungsten lighting loads typically have a higher in-rush than standard incandescent loads and are still considered incandescent.
We've seen plenty of problems with dimming and non-LED arc fault circuits. Including having Siemens engineers out to our job site to determine what's going on. They found random things on other breakers (same phase) causing an arc fault breaker to trip.
The overall point is that arc fault circuits can be tricky. The age of the breaker can and the manufacturer can play a huge role into the issues.
this is true, but most folks do not understand that LED has a large in rush. in a lot if not all cases more than an equal amount of traditional incandescent loads
