King’s College London, a
leading research and teaching
university, has replaced
manually switch-operated ceiling
lights with about 800 high frequency
sensor-controlled lights from Steinel
at one of its halls of residence. The
move will provide payback within
two years and help fund the next
energy/carbon reduction project.

The project was prompted by
lights being left on at the college’s
Great Dover Street halls of residence.

The 769 en-suite rooms in 13
apartments are served by a network
of enclosed corridors. Lights were
often on 24/7, 365 days a year.

Keith McIntyre, energy &
environment manager, says: “We had
quite a demanding specification.We
wanted a light with an integral
control system, as well as energy
savings.”
McIntyre first saw the Steinel RS
PRO 500 high frequency sensor light
at an exhibition and was impressed.

He says: “The RS PRO 500 has totally
solved our problem. Students have
some low level background lighting
(from the 3W LED module) with the
main low energy lamps (2 x 13W)
activating as soon as someone enters
the corridor. Further lamps activate
as the person moves along the passage.

Lamps remain on for 15min before
switching off automatically.”
RS PRO 500s can act as standalone
units, so no rewiring of the
corridors was needed.
