I have a 24V LED attached to a L3DA4U1UKL-CV240 driver and a MSCF-6AM dimmer. The perceived brightness change with each press of the rocker switch is far greater at the very low end than at the high end. Why is that? Is there any way to even out the steps? This is particularly noticeable when it fades in and out because it looks like it drops out abruptly on the low end.
