A study of the installed performance of industrial luminairesJules Thorn Lighting Laboratories of Thorn Lighting Ltd., Enfield
Jules Thorn Lighting Laboratories of Thorn Lighting Ltd., Enfield In many industrial installations the luminaires are seldom cleaned except during re-lamping. This may result in substantial loss of luminaire light output and therefore of task illuminance. To minimise the effects, manufacturers have developed luminaires having a so-called 'self-cleaning' action. This paper reports on both field and laboratory studies made on such high-bay and fluorescent lamp luminaires.
