dimmer control means reducing the current supplied to the led lights. This reduces the output current and the intensity of the light. As you gradually lower the brightness of the led lights, you will dimming the brightness from 100% to 0%. This saves electricity when 100% light is not needed.

The control signal is a DC voltage in the range of 0-10 volts. When the 0-10 V dimmer led is turned up to a maximum of 10 V, the output current will also reach 100% of the power output and the brightness will be 100%. When the 0-10 V dimmer led is modulated to 0, the current is minimal and the light is completely off. However, if it does not to 0 V, it will not go off completely, which will cause power consumption.

The principle of DC 1-10 V dimming also describes the maximum value of the driver as 100% to 10%. When 1-10 V is dimmer led to 1 V, the light is the darkest, and it is off when 0-1 V.

So the difference between 0-10 V and 1-10 V dimming is different led lights and turn off voltages.

When it is 1-10V dimming, the dimming signal voltage is the darkest when the dimming signal voltage is 1V, and the light is off when it is lower than 1V to 0V. If it is 0-10V dimming, it will still be on at 1V, and will be completely off at 0V, so if it does not jump to 0V, it will not be completely off, and there will be power consumption and electricity consumption.
