Mounting costs put old luminaries in the spotlight
The older a lighting system gets, the more expensive it becomes to run. Some of those costs can be obvious, with mounting energy bills indicative of inefficient, power-hungry luminaries. Others can be a little harder to track; the expense of ad-hoc repairs and upkeep, for instance, or even the lengthy warm-up times that go hand-in-hand with older systems. Either way, they all add up.
For Woolhope Tennis Club, its floodlighting costs were starting to add up and its outdated metal halide system had become almost prohibitively expensive to use. The ageing luminaries were proving to be increasingly unreliable, and replacement parts that much harder to track down. Change was clearly needed.
