Abstract: In the feasibility study to management energy consumption of road lightings in Brunei Darussalam, flux regulation technique had been used to perform the energy-saving task of the lightings involved in trial. A 40 A, 3-phase regulator was used to regulate flux on 400 W high-pressure sodium road lightings throughout the trial period. Flux of lighting was regulated by the steady lowering of the output voltage from the regulator from normal operation to the minimum allowable voltage for high-pressure sodium bulbs. Twenty-six lightings had been involved in the study at the suburban area of Brunei. The findings from the trails had demonstrated that as much 92.7 kWh or 38.7 % of electrical energy can be saved from the implementation of the method with an illumination’s reduction of 52.6% respectively recorded at the end of lightings’ lines. The associated energy-cost savings was B$3,337.20 perannum. The method will also help reduce as much as 29.4 tonnes of CO2 emission annually.
