A steric retiform lamp is provided where a string of lamps are connected into a meshwork forming a steric cylinder or cone shape. A cylindrical or a conical lamp network net is formed by a complete cord connecting all the bulbs in series, wherein the cord is constructed into a multiple-concentric-ring structure sequentially, by fastening the start end and the final end of the cord together. Each bulb-holder of the inner ring is linked to the adjacent external ring in a point to point wiring arrangement.
