This is a UV light stick sized for V0.1/Printers for Ants. Priced each.
These are 24v, check your current consumption as you may need a dedicated PSU if you’re adding a lot of lights.
Each stick has 24v, Gnd, and Data In on a connector. You can add a data out line to either end to go to the next stick, but you can’t daisy chain power.
