In October 2014, we undertook a project to upgrade the lighting in a gym in Australia. The existing 400W Metal Halide lamps had suffered significant light loss over time, becoming yellow and dim. Initially, we tested our XJ-HBL150W High Bays, but the lux levels were too high. We then recalculated using the XJ-HBL120W, which proved to be the perfect solution. This upgrade provided a brighter and more suitable environment for gym-goers, meeting the customer’s requirements efficiently.
