The First and Second Corridor of the Uffizi simultaneously serve as a sculpture gallery. Originally illuminated purely by daylight falling in through large windows facing onto the Piazzale degli Uffizi, the galleries have now been provided with a very discreet artificial lighting system. This is inconspicuously mounted in and above the casement windows, from where it effectively sheds light on the magnificently painted ceiling coffers. The lighting technology is derived from the ERCO Monopoll wallwasher luminaires for fluorescent lamps, used here as ceiling washlights.
