Work has recently started on replacing the fluorescent ceiling lights in the SSL with energy efficient LED lights. The LED light fittings use less than half the amount of electricity when operating at 100% brightness. Once all the lights are installed the brightness will be reduced to the optimal level and the lights will be connected to daylight sensors, so further energy savings are expected. The work is taking place outside of library opening hours to avoid any disruption to readers and it forms part of the Manor Road Building Facilities Team’s plan to improve lighting efficiency throughout the building.
