Abstract

A lighting unit adapted to be mounted to a vertical member, preferably a pole for use at a checkout counter in a retail service location. The lighting unit includes a substantially polygonal housing secured to the pole. The housing typically includes at least three sides, a top, and a base; the top may have slots to promote ventilation. An opening is formed in the first side of the housing and defines a receiving location for the pole, situated between the top and base of the housing. A clamp plate is releasably engageable with the first side of the housing spans the opening adjacent to the pole, and releasably engages the pole to provide for easy vertical adjustment of the housing relative to the pole. Each flange can advantageously include at least one set of teeth for enhancing the gripping strength of the clamp plates and penetrating the vertical member.
