Laboratories And Practical Spaces
Laboratories and practical teaching spaces have specific lighting requirements.
Generally, these spaces require a higher illumination level, low-glare luminaires and sometimes CRI 90 is specified if the task involves accurate colour judgement. Good modelling is required, to properly illuminate the work items.
Choice of Luminaire
Luminaire selection will depend upon the application. The Sky-Dome recessed luminaire provides very good vertical illumination as well as a very uniform horizontal illumination level.
In some specialist higher education laboratories with high levels of dust or humidity, sealed luminaires such as the Cleanline should be considered.

BS 5266-1 recommends areas over 60 m² should be illuminated to a minimum of 0.5 lux. Workshops and similar rooms should be subject to a Risk Assessment to determine whether a higher illumination level is needed - additional guidance is given in BS 5266-1 and BS EN 1838.
