Lighting installations in work places must be maintained and, where required, repaired at the latest when the maintained value on the relevant reference surface according to EN 12464-1 is undercut. Hence, illuminance at workstations must be checked regularly. Predictive maintenance methods regularly record pertinent values at workstations. Lighting installation repairs are facilitated where lamps and luminaires are accessible without complication or danger. Under some circumstances, it may be more efficient to perform lamp replacements in groups after a certain operating period and to clean the installation at the same time. When replacing lamps, it is important to observe that performance and luminous efficacy as well as light colour and colour rendering properties fulfil minimum requirements regarding photometric quality criteria.
