I agree that the dimming control voltage should be measured to make sure that it can go down to 1V or lower. If it can't go that low then I suggest putting a meter in series with the dimmer contol output to measure the DC current at the lowest dimming setting. Each light's driver should be sourcing no more than 2 mA at the minimum dimmer setting. So for example if you have 5 lights and it's drawing more than 10 mA at the lowest dimmer setting, then one or more of the lights is defective.
The Lutron dimmer specs say they can "sink" at least 50 mA, and so they can operate at least 25 lights that are sourcing the maximum of 2 mA.
