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...
