H-beam is a very simple structure, but its shape and weight make it well suited for use as a base for the lamp. H-1 is one of a series of lamps designed using the H-beam. To maintain the H-beam's simplicity, it is assembled from simple parts made of sheet metal bending, bolts and nuts. The pole of the lamp and the horizontal bar with the LED light source are assembled with the clamp, making it easy to adjust the angle, height and length.
