With an upscale lighting operation, a rethink of the technology can reap enormous energy-saving benefits for the user. In some cases, the surrounding neighbourhood can also be better off.

This was the situation when the Port of Auckland's lighting towers were given a major rethink by Philips Lighting, says senior product manager Carol MacDonald.

"The scale was huge, the towers' floodlights gave off enough light to turn night into day for around 20 hockey fields," says MacDonald. "Our lighting engineers looked at two issues addressing the extravagant power consumption of the luminaries and also the ongoing problem of light spillage. This had provided a glaring distraction for onlookers at night, even from across the Waitemata harbour."

Philips recommended that the Port Authority switch to using Philips Lighting Optivision floodlights on all its towers.

"Optivision produces three times less spillover than other asymmetric floodlights and ten times less than conventional floodlights, reducing the eye sore for neighbours," she says. "Secondly, thanks to minimal internal reflection in the Optivision's optics, a 20% higher light output ratio (LOR) is achieved than with most other asymmetric floodlights. There-fore, fewer Optivision floodlights in the new installation were needed to achieve the required lighting level over the same area, reducing the Port of Authority's electricity bill by a staggering 15-20% per annum."
