If so, please state your B Most external public spaces using LED lighting can apply UGR membership number: ................................................................................... C The CIBSE Journal CPD Programme The UGR may only be estimated using software D UGR can be usefully applied directly to all internal occupied spaces E Without knowing the specific application, UGR cannot be evaluated 3.For a 1,000lm output luminaire with the near Lambertian distribution in Figure 3, what is the approximate luminous intensity when viewed at 45 from the normal to the luminaire? A 100cd B 150cd C 200cd D 250cd E 300cd 4.Which of these is least likely to be true for a luminaire with a microprism diffuser? A It gives tighter control of light compared with opalescent diffuser B It always prevents veiling reflections and reflected glare C It will be manufactured from acrylic, polycarbonate or silicone resin D Viewers from more distant parts of the room are unlikely to suffer from discomfort glare E When applied appropriately in an office workspace, it may well have a greater overall efficiency compared with a luminaire with simple opalescent diffuser By participating in this CPD module, you consent to sharing your details with Tamlite.
