THX 1138 is a floor lamp made of aluminum and steel and liquid-painted in matt white or black. A large disc, which rests on a thin stem holds the light source. It comes in two versions. One is the THX 1138 T, with a diameter of one meter disc, which has a strong impact, almost becoming a fixed element. The other, the THX 1138 S, of smaller, more commercially viable size, is a traditional floor lamp. Both lamps are equipped with 250 watt halogen E14 bulbs with dimmer control. The THX 1138 T also comes in a de luxe version with a combination of halogen and RGB LED light and with a remote control to set the colour filters.
