In most areas the fittings were replaced on a point-for-point basis, though wherever possible the opportunity was taken to reduce the total number of fittings.Philips GreenSpace IP44-rated downlights were used extensively in the project, utilising different light outputs to meet specific lighting requirements. The 1,100 lumen version has replaced surface-mounted 2D fixtures, as well as 1 x 18W, 1 x 26W and 2 x 18W compact fluorescent downlights. The 2,000 lumen version of the GreenSpace proved an ideal alternative to 2 x 26W fluorescent downlighters, while single and twin T8 fluorescent fittings in internal corridors were replaced with the 200 lumen GreenSpace. In addition, PowerBalance luminaires have been used in offices, examination rooms, consultation rooms and interview rooms, with CoreView luminaires installed in wards that previously had surface-mounted T8 luminaires.
