The old debate over whether luminaires are electrical appliances or design objects is obsolete, as the role of appliances that produce artificial light is now undisputed. They enhance safety, quality of life and the environment, while minimising their environmental impact. This is thanks to the awareness of manufacturers and designers, who have developed safe, reliable products that also meet the photometric, technical and environmental requirements imposed by international standards and the market. These are key factors for manufacturers, which IMQ supports by offering product and system certification; performance, energy efficiency, mechanical and environmental testing, and photometric measurement services.
