Long life lighting for City University

 

Installation of Chalmor’s long-life Endurance luminaires at the engineering laboratories of City University London has resulted in reduced life cycle costs as well as improved lighting quality.

Previously, the laboratory had been using a mixture of sodium and mercury light sources and the lighting levels and light quality were not considered suitable, so a decision was made to replace the lighting.

“We carried out a life cycle costing analysis, comparing Chalmor’s Endurance fittings with T5 fluorescent fittings,” explained Stephen McKinnell of the University’s Property and Facilities department. “Over the life time of the installation we calculated we would save at least £50,000 by opting for the Endurance, much of it on maintenance savings because of the exceptionally long life of the fittings. Having worked with Chalmor on a previous project, we were also confident we would receive a high level of technical support,” he added.

Long life was a key benefit for this project because of the difficulty of gaining access to light fittings for re-lamping. Endurance luminaires give a life of at least 60,000 hours, as compared to a maximum of 20,000 hours for standard T5 fittings. As a result, in most applications Endurance lamps never need replacing during the life of the fitting.

Installed by McGoff and Vickers, the Endurance luminaires have not only provided a lower installed load compared to T5 fittings, they have also greatly improved the lighting quality with an average three times increase in light levels across the space as well as better colour rendering and colour appearance.

“Users of the space have been very pleased with the higher visibility created by the new lighting, which also has significant health and safety benefits,” Stephen McKinnell continued.
