Conventional 400W HID lighting at CourierPost depots around the country has been replaced using PowerSave Light’s 200W high intensity fluorescent (HIF) highbays and 110W floodlights.
Energy savings achieved from an industrial lighting upgrade is one thing but more important, says New Zealand Post Properties national asset manager Keith Morris, is a quality lighting outcome.
“As a busy 24-hour operation with multiple vehicle movements good lighting is critical to operational safety as is the ability of staff to clearly read address labels on packages.
Hamilton CourierPost depot manager Matt Johnstone says the upgrade at the depot in October 2009 had a profound effect on the “brilliance” of inside depot lighting.
“Staff said walking into the depot after the upgrade was like walking into a lit stadium because of the white colour of the lamps. They also said reading and sorting mail is now a lot easier.”

"Power Save was right on the money. The kilowatt hours consumed was just over half that of the 400W sodium HID lamps including ballast losses and overall lighting was better.
I'm no lighting expert but their bright daylight colour has made a world of difference with improved clarity and virtual elimination of annoying glare off stainless steel tanks, vats, process vessels and other equipment working around the plant.
Staff have also commented on how much brighter and clearer everything appears and how much more comfortable they feel working around the plant without orange-yellow glare from the sodium HIDs.
And because Power Save lights have a power factor of 0.99 of better there is no requirement for power correction units on primary lighting circuits.
We are replacing all exterior floodlights at another industrial site with Power Save floodlights and proximity sensors which will reduce exterior lighting costs by as much as 70%."

"Metal Skills' staff love the light and that the roof operates like one huge reflector. With the white colour of Power Save lights, the inside of the building actually looks like it is daytime, even at night, and I know this helps cheer the guys up when they get to work for the night shift.
I am also pleased that our lighting has improved staff safety. Power Save lights restart immediately, so if there is a 'brown out', machine operators are much safer than with normal lights.
The end result is our lighting will use less then half the power of a typical factory / warehouse. For us it means we can redirect the $30,000 saved into other areas that will add value."

"Pacific Hygiene Ltd recently constructed a purpose designed distribution centre for health and hygiene products. Having never owned our own DC previously there were a lot of questions over what systems and technology were required that would actually create honest measurable efficiencies. However after seeing the savings produced from electronic fluorescents the lighting options were easily answered.
We decided early that having good industrial quality lighting that was economical, innovative and flexible to use was of high importance and so decided to use highbay lights from Power Save Light Company. Even though they are placed at an 11m height with spacing of over 6m they deliver excellent working light in dark or overcast conditions.
As well as the saving in electricity costs one of the key features of these lights for us was the ability to turn them on an off without delay and have them controlled by movement sensors and light sensitive switches.
We import 400 containers per year and most of these are delivered and collected during the night. Using PowerSave's Energy Saver Floodlights externally gave us the ability to fully light our yard automatically with sensors when trucks arrived, making the movements safer and easier for the driver."

"Metal halides are sensitive to voltage fluctuations and tend to shut down when trawler crews engage winch motors to set and retrieve nets.
Crews are plunged into darkness while trying to work in rolling seas and have to wait for metal halides to cool and restrike. Power Save floodlights are not affected by power fluctuations and have performed well since fitted to the trawler fleet."

"We wanted to improve our workshop lighting and coincidentally came across Power Save Light Company when I was blinded by the lights from their stand at the 2006 EMEX Show.
We also had a problem in that the existing lighting circuit was at its load limit so we could not add more lights to increase the light level.
We went ahead and replaced the existing lights and added 10% more light fittings. We ended up halving our load, improving our lighting and reducing our power costs.
We are impressed by the way Power Save Light operates and have installed their lighting in our new factory as well as additional buildings retained by the business as investments."

"At Rayglass our major electricity costs are from lighting. We wanted to reduce our costs but it was also important for our showroom lighting to enhance the look of our premium products. With the Power Save lights we have achieved both; the daylight colour of the lights creates a bright, clear look and in the production facility the light quality ensures clarity and excellent colour rendition which is important for us.
We have reduced our electricity costs by more than half and will be looking at light sensors to reduce it further.
One of the pleasing outcomes was that we recovered the capital cost very quickly and reduced our operating costs immediately."
Adam Wickes, Rayglass Boats
"Our 200 watt Highbay lights from Power Save Light have transformed a dullish assembly hall into a place usable by day or night for intricate machine assembly. At 5m up we get 600 lux, exceeding our >/=300 lux specification. The bright white and flicker-free light gives easy identification of electronic component colours, as well as easy observation of defects and smearing on stainless steel surfaces.
Priced similarly to traditional 400W Highbay HID units, their ease of hanging (only 2kg on one hook), efficiency and light quality has drawn favourable comment from both installers and users. Although light level sensor controls have not yet implemented by us, their instant restart capacity enables that option, in contrast to some older lighting technologies.
I knew a better light was out there! It took some finding, but I certainly won't be buying anything else for our future expansion plans."
