25th April 2015 marks 100 years of Anzac Day.
Lightbox Studio was appointed by Bayside City Council to carry out lighting design for a cenotaph and the newly installed flagpoles at Green Point reserve. The reserve possesses a special historic, aesthetic and cultural significance in Bayside city.
Green Point cenotaph is a war memorial site built to commemorate those who served in the various conflicts that Australia was involved in. It was built in 1927 and has been used for Anzac day services for many years. It is a heritage listed site and is predominantly made of sandstone that forms the obelisk and walls and mounted on a granite base.
Lighting design to the cenotaph was briefed to be subtle while accentuating the beautiful sandstone colour of the obelisk and highlighting its details and writing. Warm white LED floodlights with beam controlled lens were used for both the cenotaph and flagpoles. An adjustable automatic lighting control system is also used to turn the lights on and off at preset times.
Lighting for the memorial site was officially switched on a few weeks ago and we received good feedback from the Council.

It’s the year the Sheep!
Our office’s Lunar New Year celebration with a traditional Malaysian dish called “Yee Sang”. Once all the ingredients are added into the dish, it is supposed to be tossed by everyone while saying their good wishes for the new year. Gong Xi Fa Chai, everyone!
Another year has almost gone and we find ourselves at the time of the year when we can let our hair down, have some fun and do some reflection.
Thank you for your support throughout the year and we look forward to working with you again next year! Happy holiday 2014, everyone!
An upgrade to the lighting at Theatre Royal in Camperdown was just recently completed. It received good feedback and we are really excited to share some photos of the new and improved theatre! All the old pendants with incandescent lamps have been replaced with new LED chandeliers which will provide significant energy savings while giving the main auditorium a glamour boost. The chandeliers were chosen with the historical heritage of Theatre Royal in mind, and we think they fit the space very well.
Below are some images of the main auditorium and an article from a local newspaper about the upgrade.
Final article in a mini-series about LED technology by Angela Fedele, an industry journalist for Sourceable.
The future of LED technology is bright as buildings young and old continue to migrate to the environmentally friendly light source.
LEDs are rapidly transforming the commercial market as manufacturers continue to unveil products that offer increased brightness, increased reliability, affordability and lifespan.
The industry is looking to LEDs for their greatest value – energy and CO2 reduction. Government and green policies which move away from incandescent bulbs and compact fluorescent lamps are helping drive this trend.
According to a recent research report, Industrial And Commercial LED Lighting Market – Global Industry Size, Market Share, Trends, Analysis And Forecast, 2013 – 2019, the growth potential is there but it is being limited by older light technology.
“The global industrial and commercial LED lighting market was valued at 12,927.9 million in 2012 and is expected to grow at a CAGR 30.8% during the forecast period from 2013 to 2019,” the report states. “However, dominance of fluorescent lamps and high initial cost of deployment for LED lamps are some of the factors inhibiting the growth of this market.”
Commercial buildings accounted for 53.5 per cent of LED usage in 2012. Countries across the globe including Australia gradually phase out inefficient incandescent light bulbs. Australia has committed to phasing out incandescent bulbs by 2020.
The report noted that the global industrial and commercial LED lighting market is currently dominated by few organised players: Phillips Electronics N.V., Osram Opto, Cree Incorporation, Cooper Industries Plc and GE lighting.
Kevin Dinh, partner at Light-Box Studio
Despite their growing popularity, LED lights may not be the energy efficient answer for every project according to Kevin Dinh, partner at Light Box Studio, a boutique firm in Melbourne. In fact, Dinh doesn’t usually use LEDs in commercial office lighting design due to light output distribution, glare issues, higher costs and minimal energy saving compared to linear fluorescent light at this current stage in the market.
Dinh also recommends speaking to an architectural light expert to really help maximise the environmental and purposeful objectives of a project’s lighting solution. Today, he has kindly outlined exactly what questions to ask the experts before leaping into LED technology:
Some manufactures might void their warranty if an LED fails prematurely due to this factor.
Heat Sink Design and Construction
Optical Glare and Glare Reduction
This extensive list of considerations is crucial to larger commercial projects whose performance is measured over time. In summary, the lumen output, beam angle, colour temperature, colour consistency, CRI, luminaire design and physical dimensions must all be considered.
Dinh asks that those behind projects looking to install LEDs to secure a Green Star “tick” understand that the policy does not focus on light sources but rather energy consumption.
“With the use of LEDs, compliance with Green Star requirements in terms of lighting power density can be a bit easier,” he said. “We would suspect though that Green Star will need to be updated to reflect the advances in LED technology so that we don’t just add more LEDs and still be under its consumption requirements because we can.”
Third installment of a mini-series about LED technology by Angela Fedele, an industry journalist for Sourceable.
Organic LEDs (OLEDs) are light emitting panels made from organic carbon based materials that emit light when electricity is applied.
OLEDs have been used in television and mobile phone industry for years but have not been very popular in the lighting industry until recently. With its flexibility and glowing surface, OLEDs have captured the attention of some Lighting Manufacturers and Designers and could open a whole new world of luminaire design and applications.
Link to the article:
With LEDs at the forefront of energy efficient lighting trends, it was only a matter of time before their organic counterparts gained momentum.
Organic Light Emitting Diodes (OLEDs) are already being used in television sets and in automobile taillights, but they are gaining more traction as they are light, flexible and provide warm and even illumination.
“Within the same LED family, Organic LED, which are light emitting panels made from organic carbon based materials that emit light when electricity is applied seem to have received some attention from the lighting industry lately,” said Kevin Dinh, a partner at Light Box Studio. “The technology has been popular in the TV and handheld device industry but not so much in lighting.”
“As OLED panels can be made flexible or transparent, they can open a whole new world of luminary design and applications to be seen in the new future.”
LG Chem had unveiled the world’s largest OLED lighting panel
While there are not extensive differences between LED lights and OLEDs, the latter come are built as extremely thin and small panels, which makes them more versatile.
Last year, IDD Aerospace/Zodiac Lighting Solutions announced it would design an OLED lighting prototype for aircraft interiors which could lower fuel consumption, carbon emissions and energy costs.
Its “extremely thin, lightweight utility light design” make it ideal for aircraft and for small urban spaces by requiring little space.
LG Chem OLED table lamp
Phillips has conducted research that reveals how electricity passes through the one or more organic semi-conductive layers in OLEDs.
“These layers are sandwiched between a negatively charged layer of aluminium, and a positively charged, transparent layer of indium tin oxide,” Phillips’ website reads.
“The whole ‘sandwich’ is attached to a sheet of glass or other transparent material, known as a ‘substrate.’ When current is applied to the aluminium layer, it is conducted to the positive layer through the organic film. As the current passes through the film, the film emits light. Different materials in the films emit different colour light.”
Last month, LG Chem unveiled the world’s largest OLED light panel and its own OLED Table Lamp at Light + Building 2014 exhibition.
According to LG Chem, OLED offers illumination that mirrors natural light more closely than other artificial lighting forms. The company added that OLED’s spectral power distributions allow people to feel “emotionally comfortable” within the light.
Andy Zhou’s OLED Plus Pendant
LG Chem’s table lamp is the first product of its kind to utilise a curved OLED panel as a light source, with the panel but a millimetre thick. It provides no glare or shadow and, unlike LEDs, produces very little heat (below 35 degrees Celsius).
It can be remotely controlled with a compatible smartphone or tablet using the LG lighting control app. The light can last up to 40,000 hours, with LG hoping to increase this to 60,000 hours by 2016.
This year, Australian designer Andy Zhou unveiled her OLED Plus Pendant, a luminary that combines a series of flexible OLED panels that move to create illumination that ranges from an area light to a spotlight. This is enabled through the use of magnets and tensile wiring mechanisms, and is designed to demonstrate the capability of the technology.
OLED Application in a retail environment
“It uses 36 rigid OLED panels to emulate future capabilities of organic technology such as its razor thin profile and flexibility,” Zhou says on her website.
The project was supported by Australia’s national research agency CSIRO and was constructed with environmental ethics in mind.
Timber components that make up the suspended column of the light are from “century-old recycled timber” sourced from the original Princes Pier in Port Melbourne, Australia, while Zhou notes “the fabric cover is manufactured by a process called 3D CNC Knitting…This process uses white polyester and grey wool thread to create a seamless textile in a single piece.”
OLED lighting could be the next big thing in energy efficient lighting. This makes for an exciting prospect for architects and designers seeking a more flexible application for their luminaries and small installation spaces.
Second part of a mini-series about LED technology written by Angela Fedele, an industry journalist for Sourceable.
This part focuses on alternative energy efficient light sources. We believe that other electric lighting technologies such as linear fluorescent, metal halide, etc. are still relevant and usable in certain applications. Daylight should also be considered and be incorporated into the design where possible. LED might not be the answer to all lighting applications, not yet anyway, until its issues are addressed.
We hope you find the article informative and enjoyable.
LED lighting is booming in popularity, and stands as one of the fastest developing technologies in the lighting sector.
There are limitations to LEDs, however, including their thermal properties, expensive production and costly maintenance.
Kevin Dinh, a partner at boutique light firm Light-Box Studio in Melbourne, has noticed a strong trend toward LED lights.
“LED seems to be the magic word associated with energy saving and long lasting lamp life at the moment,” he said.
He noted, however, that architects and designers need to be diligent with their light sources, with three options standing out.
1. Linear Fluorescent Lighting
Linear fluorescent lighting still remains the ideal choice for commercial applications and workplaces.
“There are other electric lighting technologies that are, we believe, still relevant and still have their own use in certain applications,” Dihn said. “For example, linear fluorescent light is still energy efficient and effective in office and task lighting applications; metal halide is still usable in large area lighting and road lighting.”
“Long life linear fluorescent lamps with rated lamp life up to 50,000 hours for T5 and 80,000 hours for T8 can also be a cost effective and considerable option.”
Linear fluorescent lights remain best for offices
An interview debate conducted last year by Cundall, an international multi-disciplinary consultancy saw two light experts battle out the question: Are LED luminaries ready to replace fluroescents in office applications?
Peter Raynham of the Bartlett School of Graduate Studies and the Society of Light and Lighting said LEDs are expensive to produce and maintain.
“The fact that LEDs are expensive and difficult to make is perhaps just a reflection of where we are in the current state of LED technology; it is likely that, in future, LEDs will be both easier and cheaper to make,” he said. “This will solve a lot of problems but, for the present, my feeling is that they do not quite have the edge on linear fluorescent lamps when it comes to office lighting.”
Daylighting works to complement circadian rhythms
In recent years, architects have been opening building envelopes through atria, skylights and floor to ceiling windows, allowing natural light to flow inside and minimising the need for artificial lighting.
“Daylight can be harvested in a numbers of ways such as directly through glazed windows/ façades, atriums, light wells or through the use of light shelves, solar tubes, and solar reflective mirrors to redirect into the internal spaces,” Dinh said.
Daylighting also provides heat in cold weather, though in summer, glazed windows and curtain walls may be required to keep temperatures down.
Along with energy savings, natural daylight has also been linked to improving human health and well-being.
According to Ali Sayigh’s 2013 book, Sustainability, Energy and Architecture: Case Studies in Realising Green, “natural changes in daylight synchronise and reinforce the body’s circadian rhythms, which help determine sleeping and eating patterns, brain wave activity and hormone secretion to affect a cascade of responses throughout the human body.”
Sayigh notes that “optimised daylighting increases the quality, economy and sustainability of buildings” and that horizontal skylights are the most efficient for daylighting “because they face the full sky’s hemisphere of 180 degrees receiving relatively high luminance from its zenity.”
3. Circadium Rhythm Electric Lights
“Circadian rhythm electric lights, which change colour temperature according to time of the day to mimic the natural daylight cycle (cooler, bluish in the morning, warmer in the afternoon, and cool white at twilight), have also been considered,” Dinh said. “Studies have shown that (these lights) can be used to aid sleep/wake cycle in nursing homes and hospitals or improve concentration in education facilities or be beneficial to areas where access to natural daylight is limited.”
The Drift Light, a self dimming light bulb, was designed to mimic the natural daily occurrence of sunset while “promot(ing) relaxation and an increase in melatonin.”
It moves away from the “bluer” light commonly associated with LEDs, which has been linked to surpressing melatonin.
Daylighting is best for the environment
A 2013 case study by the University of North Carolina entitled The Visibility of Research highlights the benefits of mimicking a natural environment for a building inhabitants. Doing so can lessen symptoms of dementia in the elderly, help patients concentrate and improve sleeping patterns.
“Maintaining circadian rhythmicity in a postindustrial society is becoming increasingly difficult for a culture that spends a disproportionate amount of time indoors in artificially illuminated environments facing electronic screens that largely emit light in the blue spectrum,” the report states.
Lightbox Studio had a discussion with Angela Fedele, an industry journalist for Sourceable about Light Emitting Diodes (LED) technology. Sourceable is an online news source which focuses on architecture, construction, design, engineering and property.
LED is currently leading the lighting trend which sees its uses in a wide range of applications from indoors to outdoors. LED seems to be the magic word that associates with energy efficiency and longevity. However, the technology still has some drawbacks that many might not be aware of.
Below is a link to the first part of a small series that focuses on the LED technology, celebrating its advantages as well as examining its disadvantages.
We hope you enjoy the article.
Modern architecture and design projects continue to deem energy reduction a top priority, and LED lighting is one of the core elements used to accomplish this goal.
The market for halogen and incandescent light bulbs has dimmed, with LED lighting taking their place due to its energy efficient nature.
Thel movement has been recognised by environmental groups, industry members and even governments, many of which are now implementing policies to formalise the use of LED lighting.
Kevin Dinh, partner at Light-Box Studio
When considering its application in a commercial setting, it is crucial that LED lighting design contributes both practically and environmentally.
In offices, lighting is required to support productivity, be kind to human eyes and be automated for flexible working hours. In a retail environment, lighting is used to highlight point of sale items and encourage customers in store, while hotel use lighting to create guest room ambiance.
Before architects and designers instantly seek LED lighting for their next project, however, there are plenty of benefits and limitations they may not be aware of.
Kevin Dinh, partner at Light Box Studio in Melbourne, a boutique lighting design firm providing architectural lighting design review and assessment, has worked with his team on an array of projects, including the lighting design of 41X, the new Australian Institute of Architects Building in Melbourne.
Lighting design at AIA 41X building
In recent years, Dinh has noticed a steady increase in clients requesting LED lighting, saying the technological improvements to LED have been “tremendous.” He attributes the appeal of LED lighting to its flexibility – it can be used indoors and out – along with its “efficiency and effectiveness” compared to other lighting sources.
“We have also seen many manufacturers focussing a large portion of their research and development on LED technology and luminaire development with some even phasing out other light sources all together,” he said.
Despite LED lighting’s growing popularity, Dinh noted several technical parameters that designers and users should be aware of before making their lighting decision.
Luminous Efficacy – how well a light source produces visible light
“Luminous efficacy indicates how efficiently a light source can produce visible light,” he said. “Currently, white LED can produce up to 130 lumens per watt which outshines the linear fluorescent technology at around 100 lumens per watt and certainly is a big improvement from the once popular halogen light source at around 20 lumens per watt.”
“LED efficacy continues to improve substantially. We can either have the same LED lumen package for less energy consumption or have the same energy consumption with much more light generated from the newer chips.”
Colour Rendering Index (CRI)
Colour Rendering Index
CRI denotes the ability or a light source to reveal the colour of an object it is illuminating. The maximum CRI value is 100.
“This is particularly important in applications where colour matching is required (e.g. dental labs, paint shops, etc.) or merchandise display (e.g. retail shops),” Dinh said. “CRI80+ for LED has become the norm in the industry while CRI90+ has become readily available and CRI100 is not far behind.”
Designers need to consider optical control and glare reduction
Dinh says heat is LED lighting’s biggest limitation.
“Overheating is one of the main reasons for light output reduction and premature failure. This generally happens when the ambient temperature exceeds the manufacturer’s recommendation of +40 to +55. Better thermal management means improved lamp life and luminous efficacy, which is the main focus of many researches,” Dinh said.
A 2014 study on the Effect of LED lighting on the cooling and heating loads in office buildings found that while LED lighting has the potential to provide energy savings, 75 to 85 per cent of the light electric power in LED lights is still generated at heat levels which could in turn have a negative effect on the cooling load.
Glare is another issue Dinh has come across.
The small-scale design of LED chips allows them to fit into an array of lights, offering flexible application. There is, however, a drawback.
“With so much visible light produced from a small surface area, they can produce obtrusive glare,” Dinh said. “Optical control and glare reduction are important considerations. We find that concealed LEDs rather than LEDs close to the surface tend to address this issue.”
Colour control is a limitation to LED lighting
“Another issue with LED technology is colour control and colour variations in the light output, especially in white LEDs,” said Dinh. “White LEDs generally comprise blue LEDs and a yellow phosphor coating. The colour output depends largely on the phosphor components.”
Dinh referred to MacAdam Ellipses – an industry term used to describe colour variations in terms of perception of LEDs produced by the same manufacturer.
“Some manufacturers choose to follow an international standard of seven step MacAdam at +/- 3500 Kelvin. However, there are manufacturers who don’t recognise this standard,” he said. “It’s important to note that the higher MacAdam step, the greater the variance in LEDs’ light output colour from one to another, making a constant colour surface. Some higher quality LEDs are manufactured to 2-3 step MacAdam, which means a more consistent in colour appearance to the naked eye.”
The Indigo Hotel in Shanghai demonstrates LED lighting design
While LED lighting can offer savings of up to 80 per cent on energy costs and require less maintenance, their replacement costs remain a significant limitation. LEDs cost more to replace compared to other light sources and in some cases, an entire luminaire (LED lamp and housing) needs to be replaced once the LED has reached its end of life or failed.”
“In certain applications, once examined over a long period of time, say 100,000 hours, taking into account capital costs, lamp replacement costs and energy consumption savings, an LED light source still struggles to be more cost effective than other light sources,” Dinh said.
All things considered, LED lighting remains a developing technology, though Dinh predicts it will continue to dominate the lighting market, particularly once some of its limitations are addressed.
“We will see the energy efficiency improves further with even higher efficacy, increased CRI and better thermal control,” he said. “With mass productions and the competitive market, the price will be even more affordable which will see a further growth in applications and projects. We have seen an increase in LED panels with opal diffuser on the market to combat the glare issue, making them a considerable option for office lighting. These panels’ prices have dropped significantly to be almost on par with the traditional linear fluorescent option. This might be the next trend in office lighting.”
We, as lighting designers are inspired by the architectural and interior design. We use light to interact with forms, shapes, textures and colours. Light can be part of the design features in the form of decorative pendants, floor lamps and table lamps or be in the background as discreet downlights and indirect ‘cove lighting’.
Lighting effects can be tangible and intangible. Light can affect us consciously and subconsciously (think of lighting in fast food restaurants and casinos where one is to get customers in and out quickly and the other is to retain the patron’s interest for longer durations).
We, at Lightbox Studio use a few different mediums to express our ideas and hand sketching is one of our favourites.
Below are some of our hand sketches.
A night where Melbourne celebrated the arts and culture. Melbourne White Night 2014 on 22nd of Feb was such a great success! For one night, the city did not sleep.
From 7PM to 7AM the next morning, Melbourne CBD was alive with light projections, colours, live performances, exhibitions, music… The atmosphere was pulsating with Melburnians and tourists alike that flocked to the CBD to celebrate the event.
It was great to see lighting take center stage with lots of colourful and animated projections on building facades, light installations, interactions and amazing transformations.
Below are some moments captured by us at Lightbox Studio.
Theatre Royal was built in 1927-28, during the boom period of cinema construction, at the rear of the Mechanics’ Institute in Camperdown. It was designed by a local architect W Perry Knights.
The theatre consists of a main flat auditorium (hall) which is also used for public meetings, balls and dances and civic events and a balcony seating area on level mezzanine.
Both Theatre Royal and Mechanics’ Institute are of historical and social importance to the Camperdown.
Lightbox Studio have completed a lighting upgrade design for Theatre Royal with care given to the luminaire selection to preserve its heritage style while incorporating modern technologies. Using LED light source for the upgrade, energy consumption saving will be in the order of 80% compared to the current incandescent bulbs.
We have gained approval from the Council for our design and have obtained a permit exemption from Heritage Victoria.
The construction phase will start in the near future and we will update with more images of the project once it is completed. Can’t wait!
