Hawaiian Electric is the first company in Hawaii to own high-efficiency hybrid technology lighting for use during nighttime utility work.
A key reason for selecting the light towers was the Kubota hybrid diesel engine that combines solar energy with a DC generator. Four solar panels collect sunlight to charge the 24-volt DC battery, and six 150-watt LED floodlights with horizontal and vertical 180-degree angle lighting possibilities provide high-efficiency, super bright lighting.
A light tower can provide up to eight hours of runtime off the battery bank, and when depleted, the trailer engine auto-starts to recharge the batteries. This helps lower operational costs by reducing fuel consumption and engine maintenance due to the low engine use.
