THX 1138 is a floor steel lamp, matt coated in white or black.
A large disc, resting on a thin stem, holds the light source. It comes
in two versions.
The THX 1138 T is the taller, with one meter diameter disc: it has a strong impact, almost becoming a fixed element. The THX 1138 S, of smaller, more commercially viable size, is a traditional floor lamp.
