Operating Instructions
Dimming Function
The XS1500 Pro and XS2500 models feature a dimming knob to adjust light intensity from 0% to 100%. Rotate the knob clockwise to increase brightness and counter-clockwise to decrease it.

Multi-Light Dimming Daisy Chain
For commercial growing or larger setups, you can connect multiple XS1500 Pro or XS2500 lights together for unified dimming control. Up to 20 lights can be daisy-chained.
- Connect the daisy chain cable from the "OUT" port of the first light to the "IN" port of the second light.
- Repeat for additional lights.
- The dimming knob on the first light will control the intensity of all connected lights.
