PUCK is one head, one tube and one base, repeated. Wall, floor, short, long — the parts are the same and the arrangement is yours. One in a hallway is a detail; five down a corridor is the lighting scheme. The dimmer is integrated into the lamp itself — touch the end of the tube to switch it on, hold to set the level. Nothing clicks and nothing moves. There is no control to see, only a surface that answers your hand.
