The Pablo Designs Swell collection is exactly what you need. Infinitely flexible, the Swell series answers the question: What do you want the light to do? Required when purchasing Swell String Singles, the Swell Power Feed Cord and Canopy makes the expandable lighting system possible. The power feed cord allows for large quantities of String Singles, accommodating up to thirty-four lamps with one cord. The canopy refers to the vertical mounting option, completing the kit included with the String Single.
