An electrical lighting system consists of two or more, adjacently mounted, lighting modules where each module includes an elongated, box-type housing adapted to be mounted in a predetermined arrangement on a light source supporting surface, the housing being provided with mounting and electrical supply for a light source and, further, with longitudinal guides mounted on the sides of the box and adapted to accept and secure a slotted tubular translucent light cover when the slot edges of the tubular cover are slid into the guides and split collars providing slide-in openings adapted to accommodate the ends of two or more of the covers of the adjacently mounted lighting modules.
