Mindseye specified LED fittings for Pizza Express in Solihull. OSRAM LEDs have been used in the arch above the Durban stadium in South Africa.


‘There are a lot of architects and designers (possibly even some lighting designers) who are using LED where they are really not the best solution.’ Douglas James, director at Mindseye Lighting

director, Adrian Kitching, believes that until relatively recently the application of LED light sources has been limited by their inability to match the brightness and colour rendering of other light sources. ‘More recently though, advances in LED technology have led to products entering the market that provide a direct retrofit for any other light sources, including spotlights. So, for example, a 7W LED lamp can now offer the same 600 candela luminous intensity as a 35W halogen lamp.’ Kitching says similarly the colour tolerance of the more advanced lamps has been greatly improved. ‘So, whereas poor quality LEDs may have a colour shift of as much as 400K, the better light sources have a tolerance of just 100K.’ Light Bureau has completed an interesting feature for the reception space at 95 Gresham Street, a new speculative office development by Standard Life and designed by Rolfe Judd Architects. The space includes a feature wall internally illuminated with colour changing LEDs. Nulty believes that LEDs are very close to becoming a really good, usable replacement for some incandescent

that’s some way.


‘So in a nutshell LEDs are good for some applications but not for everything, and of course, the small size of LEDs does allow us to integrate lighting in ways that we couldn’t have dreamed possible 10 years ago so certainly they are allowing a design revolution; let’s just not get too far ahead of ourselves or the technology just yet!’

sources – particularly MR16. ‘But they do need to make a final leap to combine good colour rendering, colour consistency, longevity and luminous efficacy. There are good products available which tick some but not all of the boxes,’ says Nulty. ‘However, LEDs are not the panacea that many manufacturers would have you believe and I think they are a particularly poor substitute for diffuse sources such as fluorescent modules. I’m yet to see a really convincing product that can be used for cove lighting with as good a quality run-out as cold cathode. Maybe that’s the niche OLEDS will fill but in practical terms
