Coming to a Woolworths car park near you: the retailer is planning to roll out its LED lighting scheme to other stores following the massive energy savings it achieved in Coorparoo.
LUX reports: Compared to other conventional lighting solutions, T5 is still seen by some as too efficient for the facilities team to justify upgrading to an LED lighting system. But combined with controls, even the leap from T5 fluorescent lighting to LED can yield significant savings.
Woolworths is a case in point; the retailer’s branch in the South Eastern Brisbane suburb of Coorparoo managed to save 77 per cent energy in its car park area with LEDs and occupation sensors, and earned a Peak Load Reduction Reward for its efforts.
One of the reasons the management was looking for a new solution was the amount of hours the light was on in the car park. The T5 fittings, which had an average life span of two years, were on all day and night, with no control system in place.
The entry to the car part was lit with twin 28W T5 fittings which had been retrofitted in 2012.
When most of the T5s predictably started to fail at the same time, James Dwyer of Jones Lang Lasalle (JLL), which has a national building management contract for Shopping Centres Australia’s 77 retail assets, investigated lighting upgrade options. Dwyer was looking for a solution that would last longer than the T5s and save Woolworths the costs of frequent lamp replacements and maintenance.
The JLL team had recently completed a fire stair and car park lighting upgrade at CP1, a commercial office tower in Brisbane, where LEDs were installed. The positive feedback from the building manager there helped convince Shopping Centres Australia, the owners of Woolworths, that LED was the way forward.
Lighting manufacturer Enlighten helped Dwyer complete an unbudgeted capital expense application and detailed return on investment projection, which ‘impressed the owners and ensured that my application was approved,’ Dwyer said.
Dwyer opted for Enlighten’s Chameleon light fitting, which is built for long-lit areas such as fire stairs, car parks and back of house areas.
No more wasted light
Most of the new LED fittings will only be on when needed, thanks to an in-built motion sensor which instantly switches the light from the standby 8W light output to the full 35W output for a set period of time which can vary between 15 seconds and five minutes. When the set time ends, the light output returns to standby mode.
A 90W 2 module Cetus LED low bay light from Enlighten was installed in the car park entry. This fitting actually represented a net increase in energy consumption compared to the existing T5 fixture (68W including ballast), but it was necessary to improve the light levels in this area.
All lights were replaced on a one for one basis, with each parking bays having a standard 12 chip bulk head installed. The fittings lighting the driveways are permanently on, and the ones approaching a turn have side-emitting optical lenses to ensure good visibility.
An extra incentive
Coorparoo’s Woolworths is located in an area with electricity supply constraints, which means it qualified for a Peak Load Reduction Reward. Energy-saving scheme Energex rewards businesses within the area that contribute to reducing demand on the network during peak periods by replacing lighting with more energy efficient lighting. The reward payment given to Woolworths is estimated to be $500 for this upgrade.
The savings in numbers
The new LED lighting will save an estimated 77per cent energy in the car park area, which equates to 30,504 kWh per year. The project capital cost was $21,250 after the incentive payment, with a project payback calculation from energy and maintenance savings of 2.7 years.
According to Dwyer, the project has been well received. ‘The Chamaeleon fitting is perfectly suited to our undercover car park operation and I have received an immense amount of positive feedback from the tenants,’ he said.
Dwyer is planning to retrofit another shopping centre’s undercover carpark lighting with in early 2015.

When H&M arrived on Australia’s shores last year, it did so in style with a vast, mostly LED-lit flagship store in the former General Post Office building in Melbourne.
The building’s long history, and its 18 meter high ceiling, presented the facility team with a challenge of respecting its heritage while ensuring that the fixtures were as easy to maintain as possible.
This has been achieved mainly with linear LED luminaires, recessed from existing ceiling pockets, which focus the light down the central spine of the building’s three-storey glazed atrium.
Lighting designers kept in close contact with Heritage Victoria throughout the project and ensured that the lighting installation was fully reversible and didn’t do any damage to the building surface.
As well as recessed ceiling fixtures, linear LED luminaires have been placed high up to uplight the ceiling and emphasise the columns and the geometric shape of the atrium.
Lower down, mannequins sitting on swings and posing on podiums are lit with narrow-beam metal halide spotlights. The spotlights are placed in pairs on the columns around the atrium with linear LED uplights positioned in-between the spotlights to highlight the top part of the columns above.
The arcade arches around the building are lit with linear LED fixtures concealed within the structure. All light sources are warm white with a colour temperature of 3000k.
Using mainly LED light sources means the store has achieved an electrical load of 12W/m2 for the downward light and 10W/m2 for the architectural lighting to the arches, trees and ceiling structure.

From domestic households and the catering sector to industrial applications – light emitting diodes (LED) are becoming ever more popular, because high quality LEDs in particular from renowned manufacturers such as the lighting expert Osram feature significant benefits compared to standard light sources.
They feature good colour rendering, high energy efficiency and durability, consequently reducing running costs such as power overheads or replacement costs.
The structure and principal of LEDs
Light emitting diodes consist of several layers of semiconductor material that generate light upon the application of DC voltage. In contrast to incandescent lamps an LED is a monochromatic light source, and according to its composition emits light with a specific colour. White-emitting LEDs also initially generate monochromatic light that must then be converted, and this is usually achieved with a combination of blue LEDs with a yellowish phosphor layer or by mixing the light of red, green and blue LEDs (RGB). Furthermore, specific RGB colours can be mixed to create an infinite number of colour tones by varying the mixing ratios.
PET PCBs for greater flexibility
Typical LED modules consist of several combined LEDs, a fixed PCB and various other components. A practical alternative to fixed fibreglass PCBs are flexible materials based on polymers, as these enable the production of LED modules with a high diversity of forms, in turn opening the way to new designs and lighting solutions. Flexible light engines can also be manufactured on rolls, providing simpler handling as well as automatic manufacturing and the reduction of stock keeping overheads.
A robust, non-conductive material with a high optical reflection factor is ideal for producing such flexible PCBs, and the material should also be environmentally compatible and chemically stable. Such requirements are best fulfilled with polyethylene terephthalate (PET) versions. With regard to these advantages, the lighting manufacturer Osram developed its PrevaLED Flex Linear light engine that fully exploits the benefits of flexible PET PCBs. The light engine consists of a thin and pliable copper layer in which the requisite circuit has been etched and sealed between two PET layers.
An efficient direct current solution
Due to the electrical properties of LEDs, their drivers should directly supply a constant current to the module. The reason for this is that in contrast to LED systems requiring constant voltage, other current control components on the module are not needed with systems supplied by constant current directly from the LED driver. This provides efficiency increases of 5 to 15 per cent. A sophisticated system for grouping and mixing the various LEDs (various bins) is used to achieve homogeneous voltage distribution in the LED lines various (also switched in parallel) with simultaneous constant current operation, thereby also avoiding brightness and colour deviations within the partly long and flexible systems. This in turn enables a uniform distribution of light colour and brightness, across each section and the complete module.
Light on a strip
In addition to flexibility, a special benefit of the strip solution is cutting the strip to suit the desired length, enabled by switching the LEDs in parallel. With the Osram PrevaLED for example, the strip can be cut after each segment without the module forfeiting any quality of light. One segment has a length of either 93.3 mm equipped with 10 LEDs or 140 mm with 12 LEDs, and the length itself is restricted merely by the supply of current, which must be as homogeneous as possible for all LEDs to create light with high uniformity. In this regard the distance between the current source and the LED is an important factor – the maximal length of a flexible LED module with single-sided power input is currently 1.5 metres, and module lengths of three metres can be achieved with central power input. As a consequence, the length of the light strip can be individually modified between approximately 10 cm and three metres, and installations that previously required the back-to-back switching of several modules can now be produced as one unit.
PrevaLED also cuts installation costs by up to 30% compared to standard lighting solutions. The LED strip can be bonded simply into luminaires or luminous elements, enabling the saving of valuable work time. The broad flexibility of PrevaLED comes to the fore during simple installation and the implementation of sophisticated design projects, and the PET strip can for example be bent to form a circle with a radius of just 15 cm. With a colour temperature of 4000 Kelvin, a good colour rendering index of over 80 and up to 170 lumens per watt, PrevaLED Flex is not only a genuine alternative to fluorescent tubes but also opens up new possibilities for designing light.

New designs can be simply implemented with flexible PrevaLED Flex modules.
Light with savings potential
With regard to power consumption, the emission of greenhouse gases and maintenance costs, LEDs from quality suppliers such as Osram offer high potential for savings without any sacrifices in terms of light quality. If the significantly longer lifespans are also considered, the total calculation is distinctly positive. When upgrading to LEDs, power costs according to the specific system solution can be cut by up to 80%. Incandescent lamps in this regard are characterised by an efficiency of around 10 lm/W, halogen lamps have approximately 20 lm/W and fluorescent sources have 70 to 90 lm/W. Comparable white LEDs achieve an efficiency of between 70 and 100 lumens per watt according to type and light colour, with LED power consumption (according to type) being merely 0.1 to 15 watts. This means that even highly compact LEDs provide powerful lighting.
It’s a question of quality
In order to exploit the complete spectrum of advantages inherent in LED technology, when selecting the appropriate light source this mainly concerns the quality of components. The light source manufacturer Osram has upgraded its portfolio, helping consumers to more simply identify high quality LEDs at a glance, and will present its largest LED lamp spectrum until now in the Autumn of 2014. More than 90 LED lamp types will be available in the retail market with easy to recognise, uniform designs, and the consistent look of the popular candle, drop-shaped and mainly pear-shaped classic LED lamps will be characterised primarily by their smooth, white heat sinks. The uniform designs of the Osram lamps go beyond similar appearances to also provide a highly practical aspect – all lamps are based on identical modules used in different lamps.
Retrofit lamps are especially suitable for refurbishing classic lighting systems to energy efficient and durable LED technology. An example are lamps from the Osram Classic A40 series, featuring construction sizes and bases identical to classic incandescent lamps to enable easy replacement.
Light without shadowing
Decisive for the success of a lighting technology is whether the light from a lamp is perceived as being pleasant. This in turn depends on various factors, for example colour temperature and luminous intensity. The distribution of luminous intensity in the so-called far field is also important, meaning where light hits walls, floors or table surfaces for example. Of special importance in this respect is that light is distributed homogeneously and that minimum shadowing or linear structures are seen. The optics within LED lamps are responsible for this task. Because such optics can be seen from the outside with clear lamps, these are not only a functional element but must also be visually attractive. The optic also ensures that the “technology” of the lamp, meaning its LEDs and electronics, cannot be seen from the outside.
Optics in the classic bulb-shaped lamps in the new Osram LED portfolio have been designed to largely exclude irregularities such as dark shadow lines in far field light and to achieve homogeneous light distribution, and this is achieved by the particular form of the plastic optic developed specifically for the new lamp generation. The design of the optic was developed with the aid of in-house programmed software due to these stringent technical and aesthetic requirements. Optics in the new Osram LED portfolio radiate at beam angles of up to 300° and also achieve a high level of uniformity in illumination.

Highly diverse lighting solutions
In addition to high levels of efficiency, the inherent diversity of the compact diodes is also advantageous, ranging from applications for video walls in sports arenas to the illumination of refrigerators. Because of their specific properties such as low heat generation and flat constructions, LEDs can be used in locations where other luminaires may only be installed in compliance with strict conditions – such as in fire protection applications. LEDs also generate no infrared or ultraviolet radiation, making them ideal for use in foodstuff counters and hospitals, and thanks to their tough constructions, LEDs are the ideal light source for applications exposed to high loads such as in the automotive sector. Osram LEDs also achieve very good colour rendering values of up to Ra 95.
Novel Energy Lighting sells a range of Osram LED products. One of the more popular lamps is the Osram LED Star GU10 6.5W Dimmable.

Lux Magazine reports: The government is considering ways to slash demand for energy by encouraging homes and businesses to install low-energy lighting and controls.
A consultation on ways to reduce demand for electricity was launched yesterday together with the Energy Bill, and runs until the end of January.
The Department of Energy and Climate Change (DECC) believes that a quarter of the potential energy savings to be made in homes by 2030 could come from getting rid of incandescent lamps, while lighting and controls could account for more than a third of savings in commercial properties and nearly half in the public sector (including streetlighting).
In the residential sector, the major barrier to adopting these technologies is a lack of awareness, the government believes, while in commercial buildings the main problems are the payback period on lighting upgrades and the fact that the person using a building and paying the bills is not always the one with the power to make changes.
The government is considering various financial incentives for energy-efficiency measures as well as voluntary and information-based approaches.
Engineering body Cibse has welcomed the consultation, saying it comes “better late than never”. Cibse said that simple improvements to building performance could make a huge difference to the amount of energy needed in the future.
Any new measures to promote efficiency will come on top of the Green Deal, set to be launched fully in the new year, which will provide finance packages allowing households and businesses to pay for energy-efficiency upgrades from savings on their bills.
Energy minister Ed Davey said the Energy Bill and associated measures are designed to drive low-carbon economic growth and “keep the lights on”.
Last year 39TWh of energy (that’s 39 billion kWh) was used to light commercial and public sector buildings, while around 15TWh was used in homes.

Lux Magainze report: Energy-efficient lighting has come out top in a survey of green technology investments for businesses.
Over three quarters of businesses (77 per cent) polled by the Carbon Trust said they had invested in energy-efficient lighting in the past year, while 59 per cent had invested in employee training and 57 per cent had invested in energy metering and monitoring.
Almost all businesses surveyed said energy efficiency was an important consideration when buying or upgrading equipment.
However, the survey also highlighted reservations about the transition to the new technology, with only half of respondents (51 per cent) saying they were confident about manufacturers’ energy-efficiency claims.
Hugh Jones, managing director of business advice at the Carbon Trust said: ‘Our survey showed that return on investment is the most important factor for organisations considering investing in energy efficiency and low carbon technologies.’
The survey comes as the Carbon Trust launches the Green Business Directory, which lists suppliers that have been vetted under the trust’s Accredited Supplier scheme.

New lighting at several London Underground stations that are currently being redeveloped will be all-LED.
Bob Benn, stations engineering manager for London Underground, told the Lighting for Rail conference that stations including Tottenham Court Road, Bond Street and Victoria, will get 100 per cent LED lighting when the work is completed.
Lighting for the stations was initially designed several years ago as part of the redevelopment plans, with fluorescent products in mind. But lighting teams have managed to get specifications updated to take advantage of newer technology.
‘We were basically dealing with an obsolete design,’ said Benn. ‘We’ve managed to change it all to LED lighting, but that’s been a major challenge in London Underground in order to get that through the system.’
Changing the specification to LED means London Underground will reap significant energy and maintenance savings, despite a higher upfront cost. The high cost of conducting maintenance in busy and hard-to-access underground stations means long-lasting products pay for themselves quickly. An earlier project to replace T8 lamps in a number of London Underground stations with LED tubes has saved millions of pounds in maintenance costs, paying for itself in less than 18 months.
‘From the point of view of whole-life cost, we’re very aware of the reduced maintenance of new technology,’ said Benn.
An ongoing programme of station improvements is taking place all over the Tube, and many stations are being upgraded to prepare for the completion of Crossrail.
Work at Bond Street is due to be finished by 2017, while work at Victoria and Tottenham Court Road will go on until 2018.

Most people are unaware of the negative effects of traditional fluorescent tubes and bulbs for lighting. Fluorescent bulbs emit a decent amount of light but almost 20% of the input energy used by them is converted into heat. This is wasteful, and with the ever increasing price of energy, hikes up your electricity bill. Moreover, fluorescent tubes and bulbs have a short lifespan since they use high voltage as startup (as much as 300 volts), which affects durability. In order to start a fluorescent tube the mercury atoms need to be ionized before the arc can ’strike’. It is very common to see fluorescent tubes flickering at their end of life.
LED Tubes
What’s more, fluorescent lighting is not environmentally safe, since lamps and tubes it contain mercury and phosphor to produce light, these chemicals are toxic, and get released into the atmosphere when the lamps are disposed of, making them harmful to the environment.
This makes for a compelling argument to switch to a more economical and environmentally viable lighting source. Philips T8 LED Tubes supplied by Novel Energy Lighting can provide you with consistent lighting for a long period of time. These LED Tubes have wattages varying from 8W to 24W for 2ft through 5ft length tubes, to match the output of fluorescent tubes. You will see energy savings of 60% with LED tubes, and more if you exclude ballast, switchgear, and starter from the circuit..LED Tube Lights are very durable. The MasterLED range offer a rated lifetime of 40,000hours (L70) even if used continually. The value Corepro range offer a rated lifetime of 30,000hrs (L70). Our other top manufacturers offer LED tubes with similar long rated lifetimes, and high quality light output to match or exceed their fluorescent counterparts.
And unlike fluorescent lamps, T8 LED Tubes will not flicker or cause short circuits as they are capable of using power efficiently. They are designed such that they can be retrofitted into existing electromagnetic or high frequency fixtures, making lighting upgrade a quick and simple process. Some tubes even come with rotating end-caps which make them easier to install. Philips Master LED T8 Tubes come with a 5 year warranty, so you can have complete peace of mind once they are installed.
Philips MASTER LED tube Value InstantFit has been designed by the market leading experts in LED. This range integrates a LED light source into a traditional tube form that’s quick, easy and safe to install. The world’s first LED replacement tube that requires no rewiring, InstantFit is compatible with HF fixtures and drivers in linear fluorescent tube lighting. A simple switch that reduces the time it takes to replace fluorescent with LED to just a couple of minutes per fixture.
Novel Energy Lighting also supplies T5 LED tubes as an upgrade for T5 fluorescent tubes. Available with integral fitting, or in the case of Heathfield’s T5 as tube with external driver, we offer lengths and outputs to match conventional T5 tubes. These solutions are durable and come with a 3 year warranty.
So upgrade your fluorescent tubes to LED Tubes to save energy, reduce your impact on the environment, eliminate hazardous chemicals, and reduce your cost of ownership and ongoing maintenance costs. They are the perfect option for offices, hospitals, and commercial premises
