The goal of IEA ECBCS Annex 45 was to identify and to accelerate the widespread use of appropriate energy efficient high-quality lighting technologies and their integration with other buildingsystems,makingthemthepreferredchoiceoflightingdesigners,ownersandusers.The aimwastoassessanddocumentthetechnicalperformanceoftheexistingpromising,butlargely
