|LED lighting in hospital atrium|
The halogens that were ceiling-mounted at 18 m had required regular lamp replacement after every 5,000 hrs of operation. However, the "new lights are to be on 8 hours per night, which given the expected lifetime of the fixture LEDs, means they should still be operational in 20 years. All the fixtures are low wattage; the biggest of our ø225 Series 36LED spots draw just 54 W, so the installation is both very economical in maintenance terms and carries a fast payback in energy saving,” said Steve Whiteley, operations director for Zyphos.
“The atrium has three levels,” Whiteley continued. “On the ground floor, there is a conference area and a shop that are closed during the evening. However, the main entrance is used by shift personnel. The walkways and corridors leading off from the atrium provide access to wards, theatres and other hospital facilities. So achieving the correct level of illumination was not just a matter of aesthetics, but also of traffic and safety.”
Zyphos supplied a mix of PuraLED floodlights, projectors and spotlights, a total of 46 fixtures that were all pure-white LED versions with a 5500K-7500K light temperature. The installation was completed in two days.
