Technical Features
  • Body of high-pressure die cast aluminium, first given a zinc chromate substrate, then finished in RAL7035 light grey polyester powder coating for optimum protection against harsh environments
  • Narrow, medium and wide beam, double asymmetric light distributions
  • Toughened front glass, secured within an aluminium frame
  • Double asymmetric reflector system of high purity, polished and anodised aluminium. Incorporating an internal baffle to improve efficiency and reduce glare
  • Galvanised steel stirrup, with additional locking screws
  • Sealed to IP66; with silicone rubber gasketing
  • Electrical connection box (IP66) housing ignitor, located on the side of the stirrup, fitted with 2 x GORE membrane breathers
  • Simple aiming using a separate aiming device for accurate results
  • Breather management system regulates air flow through the cable hose and in/out through IP67 GORE membrane. This method alleviates stress on the front glass

Features

Abacus Light Control System
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 Challenger® 1 the Abacus Light Control System consists of a series of complimentary measures to effectively control light pollution.

The Abacus Light Control System
Double Asymmetric Reflector
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.

Double Asymmetric Reflector
Internal Baffle
The internal baffle re-directs upward stray light back into the floodlight beam, providing increased efficiency. At angles above the beam the baffle shields direct lamp glare (fig 3).

Produces sharp run back above high peak resulting in greater overspill containment and minimal intrusion to adjacent areas bordering the installation (fig 2).
