lighting in retail
DESCRIPTION
We believe that a high quality lighting solution is about more than meeting standards. For this reason, we developed the Lighting Quality Standard (LQS), which focuses on the provision of optimal illumination that ensures the comfort and wellbeing of users. The LQS is a unique assessment methodology based on 20 objectively quantifiable criteria that enables the clear evaluation of a lighting solution's quality. A correctly designed lighting solution is able to set a desired mood, create a positive atmosphere, aid customer navigation, promote goods and motivate purchasing behaviour. Therefore, for RETAIL applications, we place a strong emphasis on the LQS criteria that are most able to support the provision of a high quality lighting solution.TRANSCRIPT
