RIDI has supplied 2000 luminaires from its AIDA range of suspended direct/indirect luminaires to buildings 509 & 519 at Pfizer's pharmaceutical research and development facility in Sandwich, Kent.

In a somewhat unconventional approach luminaires were redesigned to suit a predetermined layout. The results was the single lamp AIDA which has now been introduced as standard to the UK. This luminaire gave a suitable balance of illumination and uniformity.
