The objective of this scheme is to provide an assurance of the validity of the photometric data published by manufacturers when describing the performance of their lighting products.
A manufacturer participating in this scheme will be required to undergo a thorough inspection of their Laboratory in order to verify the adequacy of the photometric equipment, documentation and the technical competence of the staff to carry out photometric measurements using integrating spheres. A manufacturer who meets the requirements will be permitted to describe their Laboratory as a ‘LIA Laboratories Registered Photometric Laboratory’. LIA Laboratories will ensure, by regular inspection, that the quality of the measurements made by a ‘Registered Laboratory’ is maintained at an appropriately high standard.
The LIA Laboratories' technical scheme document details the requirements lighting manufacturers must fulfil in order to work towards certification.
