Highly efficient road lighting luminaire incorporating the latest LED technology 1 The heat sink and optic are protected to prevent gathering of dirt and dust and contoured to maximise airflow and minimise wind loading 1 Optimised heat dissipation extends LED lifetime 1 Designed for use with high-efficiency LEDs in 49W 1 Post-top or side entry mounting, with adjustable steps respectively) Entry connector for easy control

Energy efficiency Total Cost Amortisation Chart Total Life Cost Analysis This example compares a 98W Indra to a 150W HST lantern which fulfils the same lighting requirements. Dimming is automatic (input is via a control line from the switching cabinet) and adjustable according to a pre-set time schedule. Power reduction is in two (bi-level) stepped increments: at 50% and 100% of light output. As LEDs have a linear relationship between light levels and energy consumption, during the dim-down period power consumption is halved. Consequently, with a simple and accurate setting of the cabinet clock,...
