Power Force Technologies (Stand No. 509), the Singapore distributor for Carmanah Technologies, is displaying the Canadian manufacturer’s self-contained radio-controlled, solar-powered airfield lights, including units suitable for helipads, obstructions, runways, taxiways and thresholds. The equipment employs light-emitting diodes rather than battery- or generator-powered incandescent bulbs, thus making the lights independent from fixed power grid supplies. Singapore Changi is one of several international airports using such units.
