Our original zigzag pendant light is hanged with stainless-steel wires in a gentle curve along the furniture layout. It illuminates both the 5700mm-high wooden louvered ceilings and the PC desks/ reading tables below. We hanged 23 lighting units in construction to minimize the costs: each made of double c-channels (75mm-wide, 40mm-high, and 3100mm-long) assembled one above the other containing 2 seamless fluorescents upward and 4 downward (33W, 1500mm).
