What is the sample size for verification testing of a luminaire that has multiple identical light sources, e.g. a 3-light fixture. Is the sample size an individual lamp, or three sets of the identical light sources per Directive 2012-01? Follow

The sample size as outlined in Directive 2012-01 refers to each individual light source. For example, if a fixture has three heads that use the identical GU24 based CFL lamp, the sample size for performance criteria that requires three samples, would be three lamps total, not nine lamps (I.e. three sets of three lamps).
