For WEC's and Power T's, power up to 200, dual RGB-LED 24V pixels, across 200-feet. Will also power larger lamps in less quantities and distance. Use inline in a single direction with Power T. Power a WEC3 directly, or with a Basic T, back-feeding power to the controller while you power forward to the lights. Do not cross voltage-RGB-LEDs do not like to receive power from both directions, and this will decrease their lifespan and potentially cause data latency.
