Trama was designed in two versions, the suspension and the up-down, the latter being vertically adjustable by means of a zama spherical counterweight. Each is available with two different sizes of cap. Through its characteristic pattern silk-screened polycarbonate diffuser, the quality of light is enhanced to the maximum and diffused evenly in the atmosphere, without reducing brightness and without the tiresome dazzle and false shadows created by a direct light beam.
The polycarbonate cap, unlike glass, makes the lamp very light so that it can also be used for plasterboard false ceilings. The bulb is protected by a thin and well ventilated pyrex glass to ensure durability. Trama is suitable for rooms with heights varying from 260 to 340 cm.
