Glamox remanufactures 25-year-old luminaires for Oslo hospital

Glamox has remanufactured and upgraded luminaires which it supplied to the Oslo University National Hospital 25 years ago

Rather than replace the ageing fittings, the company developed a custom LED gear tray – comprising the light source, driver and diffuser – to make it easy to swop out the original T8 fluorescent light sources.

The 67 ‘Indi’ luminaires, pictured right,  in the corridor ceiling were provided by Glamox in 1999 and have a distinctive grill finish to the diffuser which will be retained.

Glamox says this approach reduces waste and lowers the environmental impact when converting the building’s lighting to LED.

‘It’s only fitting that one of the world’s leading hospitals has 21st century lighting to match – lighting that reduces its carbon footprint and supports a circular economy,’ Toril Bache Jenssen of Glamox told the Circular Lighting Report.

‘Compared with the older fixtures, the smart lighting will enable the hospital to cut its electricity use for lighting by 60 to 80 per cent, which is significant given that most of the lighting is on 24 hours a day, seven days a week.

‘It is also long-lasting, so it will free up the time of maintenance staff as the previous T8 fluorescent tubes had to be replaced frequently. They had an 8,000-hour life compared to 100,000 hours for the new LED lighting.’

The fluorescent luminaires in the hospital’s emergency ward are to be replaced with 1,200 new connected LED luminaires that are controllable remotely and can dim down when people are not about.

The luminaires comprise different specifications of Glamox C-95 ceiling lights. These slim ceiling lights will be connected by DALI to a Light Management System. In addition, there will be control panels in the corridors and rooms.

The lighting refurbishment is part of a major ongoing expansion of the National Hospital.
