A combination of efficient lighting design and careful floodlight design has rewarded Abacus with an international reputation for pioneering high performance Floodlighting combined with effective control of obtrusive light.Specific to Challenger1 the Abacus Light Control System consists of a series of complimentary measures to effectively control light pollution.
The double asymmetric reflector is designed to ensure full flow of light over the lit area from each floodlight. With the main beam emitted from the floodlight at an angle of 60° forward from the normal to the front Glass, it results in a flat appearance (fig 1). The benefit is that less of the reflector is visible to spectators and onlookers, resulting in low glare to the surrounding locality.
