Gonio Scheme

LIA Gonio Photometer Scheme


To provide assurance and validity of photometric data produced by manufacturers when describing the performance of their lighting products, and minimising costs during product development.


Annual inspections and Audits by the LIA Laboratory experts will ensure your equipment, testing processes, quality management system and technical competence of staff are of a required standard and in return will entitle you to be a ‘Registered Laboratory’. This will not only add huge value to your photometric data, it will show your clear commitment to quality within the lighting industry.
