Clamp for an elongated lamp
View Patent ↗A clamp for an elongated tube style white such as a versa tube. The clamp has one fixed side that holds the versa tube's mounting structure therein. The other side of the clamp is movable, and pivots between an open position and a closed position. In the closed position, the lamp is held into place, and in the open position the lamp can be removed. A single screw that holds the clamp into the open or closed position is knurled and hence the device can be removed without any tools. The two sides of the clamp occupy different longitudinal positions so that they can be placed directly next to each other, and one opened without moving or disturbing the other since the two sides are in different longitudinal positions.
