Technical Data
last update: 25/08/2026Description
Downlight designed for use with a 2x18W compact fluorescent lamp in the horizontal position. Thanks to its professional optics the luminance of the reflector can be limited to values smaller than 200 cd/sqm with angles of observation greater than 60° with respect to the vertical axis (ref. CIBSE LG3 and DIN 5035 Teil 7 A60). Two brackets made of galvanized sheet steel are fixed to the die-cast aluminium perimetric ring to support the component box, also made from sheet steel. The lamp holder is fixed to the component box, which can be extracted from the fitting for easier maintenance. The superpure aluminium reflector is screwed to the fitting at the bottom.
