NANO PYROS: compact professional projector for halogen, metal halide and RGB LED lamps. An extremely compact lighting fixture equipped with precision optics for high efficiency: NANO PYROS can be used for discrete, low-impact installations without sacrificing any of the precision and potential of single-socket discharge lamps. In the halogen versions, NANO PYROS houses an electronic transformer in the projector body; in the discharge versions the electronic power unit is housed in a box mounted on the fastening bracket. The electrical connection on the halogen version is housed in the base of the fastening bracket, concealing the power cord that is protected from accidental yanking.
