sunflower-image-press-release

Since their debut, Sunflower Highbays (or UFO Highbays as they are also known), have been cornering the market. Their huge leap in success falls to several key benefits held over their predecessors; the most versatile of which is their enhanced minimalistic profile and extreme light output. Through consideration of the sheer number of applications suited to Industrial Highbays, it quickly becomes clear just how many businesses and individuals can benefit from the new Sunflower Highbay advancements.

Such improvements are possible due to intense light outputs via the unique ‘Sunflower’ aesthetic, which allows for maximum heat dissipation contributing to the effective use of more powerful components and a more reliable running life. The nickname Sunflower attributes to the yellow centred chips which geometrically harmonise to mimic the visual characters of an actual sunflower.

Thanks to LED technology, LED Manufacturers are now able to produce LED fittings such as the Sunflower Highbay with higher light outputs than their Metal Halide counterparts whilst decreasing the power consumption by more than half.

The new and improved significantly smaller profile allows for much greater range of use, where previously Highbays, (LED or otherwise) involved large bulky Drivers and Reflectors that when combined created a tall and heavy unit. Though retrofitting options do exist in the form of LED Corn Lights and similar designs, these are ineffective comparatively and significantly more expensive, especially when compared to the benefits received from a dedicated Sunflower Highbay.

The absence of an exterior Reflector in the new Sunflower design, allows for a flat, non-intrusive floor facing profile and feature a much more compact Driver allowing for the LED chips to sit flush against the fixture. This not only creates a more streamline aesthetic, but also frees up otherwise occupied ceiling space – eliminating a potential complication with older Highbay models for warehouses featuring high levels of forklift use.

Many Sunflower Highbays feature strong polycarbonate lenses; providing extra durability and impact resistance. The improved Sunflower design would particularly benefit applications such as Gymnasiums and Sporting Arenas where damage from stray sporting equipment would be significantly decreased.

Many new Highbays take advantage of the slimmer design, offering adjustable arms to turn a ceiling mounted Highbay into a completely adjustable high powered Floodlight. Those rated to IP97 offer the most versatility with many businesses already substituting their traditional Floodlights for these adjustable, extremely luminous Sunflower Highbays.

Previously, heat was dissipated directly upwards through a hefty Driver housing often utilising a frilled design, whereas these new Sunflower Highbays make the most of their surface area through numerous cut outs and holes around the entire excess of the fixture. This allows heat to dissipate from extra positions that are completely separate to any components, further minimising potential wear from excess heat.

In summation, the advances of the new Sunflower Highbays amount to almost zero maintenance, longer lifespans and highly increased efficiency to name a few. Sunflowers are second to none in the current Industrial Highbay market.

Energy SchemeThe Essential Services Commission is responsible for bringing in the VEET Scheme back in 2009, along with it the ESS scheme in New South Wales and the EEIS in Canberra are fighting for the same goal to lower energy use and in turn pollution across Victoria, New South Wales and Canberra. They hope to accomplish this by offering rebates on energy efficient products, making the switch more affordable and encouraging investment with the ultimate goal of reducing green house gas emissions. Since then businesses have continually grown offers and options around this rebate scheme, despite the substantial accreditation processes required to become a supplier for these energy schemes sadly not all of these options are created equal. To clarify the significance of this statement correctly, utilising these schemes can yield immense savings for you the consumer through continual energy savings spurred on by the rebate funded energy efficient lighting. You can’t just trial and error your way through however as the rebate is available only once, therefore making the right choice the first time is essential. Lamps and fittings that fall within the schemes guidelines range widely in brand and model and with those varying suppliers comes varying levels of quality. Sadly the schemes efficiency requirements are solely focused on energy output, the overall efficiency and longevity of the light is not assessed nor assured. A lamp may run with fantastic energy efficiency but corrode quickly with time. If you’re looking to get the most of these rebates, long term viability is an obvious goal.

This post is not pushing to sway you in one direction or another but instead to point out the often overlooked fact that meeting the numerous schemes standards does not necessitate quality. As discussed, with such limited chances heading into the decision with as much information as possible is the key to a positive long term outcome.

Long standing businesses are a great place to start, new businesses started up to take advantage of the schemes, encouraged to make a quick profit but often without the necessary long term foresight and experience gathered over a long career to make informed decisions on their product. An established company that has existed before the schemes were put in place has already spent years choosing and culling product to find the level of quality required to conduct long term business. Another key factor to keep an eye out for is warranty, a long warranty shows faith in the product and allows the most time for you to reap the rewards of the scheme without fear of being left in the dark. It’s important to note that although a long warranty may seem foolproof you need to rely on the company to achieve a successful claim, a young company imposes more risk offering a warranty longer than the company has been in business should be treated tentatively, although there is no guarantee they will go out of business there is no assurance they won’t either. This loops back around to the first point of finding a long standing business increasing the chances dramatically that they will be around to fulfil the warranty for years to come.

Ultimately in any situation where one is spoiled for choice statistics demand that not all are going to be ideal, but knowing that discrepancies within the schemes exist and not all lighting and their suppliers aren’t created equal is half the battle, armed with that knowledge you can make a more informed and hopefully more fruitful business decision.

IP Ratings are used to classify different degrees of protection against intrusion or immersion

IP Ratings are used to classify different degrees of protection against intrusion or immersion

The world is ever-changing and evolving around us and with the influence of technology as one of the largest factors, we are constantly made to keep up with the changes.

Technology in lighting has highly evolved and with the growing popularity of items such as LED lighting and smart phones, the public should be becoming more aware of IP ratings and their importance – let’s face it how many of us are frequently worried about dust or water damage to our precious phones? The same concern should also be directly applied to lighting.

Dust and water-proofing used to be features associated with the kind of tough phones you’d expect mountain-climbers to pack into their rucksacks. Or the phones people on construction sites take to work. Times have now changed and the ability to brave the elements in phones continues to develop. These days waterproof and water-resistant smart phones on the market are not huge ‘rugged’ phones, but sleek, pocket-friendly handsets with some of today’s best features.

Protected devices are judged by the Ingress Protection Rating, also known as the International Protection Rating (IP rating). This rating system is also directly applicable to lighting and is essential to products where it is important to monitor or stop the ingress of dirt and/or water (such as outdoor accent lighting, garden lighting and swimming pools/ponds as well as indoor areas where water is present such as kitchens, bathrooms and laundries).

IP stands for Ingress Protection and is fundamentally a rating system developed by the International Electrotechnical Commission or the IEC. The system is now being used to classify different degrees of protection against intrusion or immersion. The IP rating is an informative way to communicate how well a product is guarded against dust or water from damaging a product 1

In an IP rating the first number always refers to dust protection, while the second refers to water resistance. For example, a rating of IP54 would mean a dust protection rating of 5 and a water resistance rating of 4. Dust-resistance levels go from 0 up to 6 while water-resistance goes from 0 to 9 (see table for further explanation)

When it comes to light fittings, many people are concerned if the fitting is suitable for their bathroom or outdoors. Rui Pi (Compliance Officer) from ANL Lighting states,

Some questions we often get from our customers are ‘is this fitting suitable for my bathroom’ or ‘are these fittings suitable for use outdoors or in wet areas near a pool’, so understanding IP ratings is fundamental knowledge for our representatives to pass onto our customers.”

As a recommendation, ANL Lighting suggest a minimum of IP65 for outdoor applications in temperate climates. Rui Pi suggests,

Generally we recommend IP65 for exposed outdoor lighting with the option to drop down to IP44 for covered areas i.e. Patios, where there is roof cover and low exposure to water and rain.”

Due to the growing popularity of beautifully landscaped gardens and outdoor accent features, alongside the concerns of product performance to natural elements such as dust and rain, Vibe Lighting are set to launch their new Elite series of LED Recessed Ground Lights and LED Outdoor Projector Lights.

With an IP rating of 68, the soon to be released Elite series of products offer supreme waterproof and dust protection. With the LED Recessed Ground Lights and LED Outdoor Projector Lights’ IP68 rating, coupled with energy efficient CREE LED chips, advanced construction and a 3 year warranty, makes these products the first choice for anyone looking for the perfect lighting solution to wet indoor or outdoor environments.

The Vibe brand of light fittings is synonymous with style and quality. Vibe supplies an ever growing network of lighting retailers and hardware stores, electricians, landscape designers, architects and builders with a wide range of lamps, light fittings and other electrical merchandise.

Clean, clear and bright light is paramount to all medical staff

A hospital’s number one precedence is patient care. Improving patient care has become a priority for all health care providers with the overall objective of achieving a high degree of patient satisfaction.

‘The Australian health system is world-class in both its effectiveness and efficiency: Australia consistently ranks in the best performing group of countries for healthy life expectancy and health expenditure per person.’ (Doctor connect, 2015)

The quality of patient care is essentially determined by the quality of infrastructure, quality of training, competence of personnel and efficiency of operational systems. However, fundamental to any hospital effectiveness is the quality of medical and technical expertise and the equipment in practice. One (of the many) crucial aspects of medical diagnosis is from clinical observation.

Regular measurement and documentation of clinical observations are essential requirements for patient assessment and the recognition of health deterioration. An important aspect of medical diagnosis through clinical observation is the reliable detection of Cyanosis.

Cyanosis is a physical sign where the skin and mucous membranes give off a bluish discolouration, indicating that the oxygen levels in the blood are dangerously depleted. Cyanosis is associated with cold temperatures, heart failure, lung diseases and smothering. It is seen in infants at birth as a result of heart defects, respiratory distress syndrome, or lung and breathing problems. (Gale Encyclopedia of Medicine, 2008) While pulse oximeters are used in operating rooms and recovery areas, there are areas within hospitals where these are not universally used and there are some medical conditions, for example where patients have poor peripheral circulation, which can make their use unreliable. In such instances,the ability of medical staff to reliably detect the onset of cyanosis by visual observation may be critical to a patient’s health and well being.

Colour is observed by reflection of light from objects. Daylight or artificial light sources are not optimal for detecting cyanosis. The detection of cyanosis requires an adequate light wavelength of around the 660nm. (Midolo, 2007) If the output is too low a patient’s skin colour may appear darker and they may be misdiagnosed. Subsequently, if the output is too high it may disguise the cyanosis and it may not be diagnosed when it is in fact present. The underlying key is that clinical staff cannot rely on visual detection alone.

Extensive clinical trials carried out at Royal Prince Alfred Hospital in Sydney in the early 1970s identified a number of lamps that were suitable for reliable diagnosis of cyanosis. This led to the publication of AS 1765:1975 which included a graphical method of determining which lamps were suitable based on colour temperature and the colour rendering indices Ra and R13. An outline of the method can be found in AS/NZS 1680.2.5:1997 Appendix H.4

The lamps identified in the 1970s used halo-phosphor technology and generally had a continuous spectrum. In the 1980s, however, tri-phosphor lamps entered the market and over a period of time have replaced halo-phosphor lamps except for special purposes. Tri-phosphor lamps provide major efficacy and life benefits.

As part of a review of AS 1680 in the 1990s, Standards Australia Committee LG/1, Interior Lighting, revisited hospital lighting. Resources were not available to carry out the large scale trials of the 1970s, which had established the original cyanosis observation criteria. However, using the data from the first trials and the known reflective properties of blood, a methodology for calculating a Cyanosis Observation Index (COI) was established and published in AS 1680.2.5:1997. This publication sets out lighting recommendations for a variety of tasks carried out within hospitals and medical facilities, specifically for particular tasks associated with clinical observation, treatment and care.

The COI is a dimensionless number and is calculated from the spectral power distribution of a lamp. The methodology calculates the colour difference between blood viewed under the test lamp and when viewed under the reference lamp. To meet the Australian Hospital Standard and be suitable for detecting cyanosis in hospitals, all lamps must meet two criteria: a Cyanosis Observation Index of less than 3.3 and a colour temperature between 3200K and 5500K. Lamps with colour temperatures above 5500K provide false positive diagnoses of cyanosis and lamps with colour temperatures below 3200K results in failure to detect cyanosis.

During the development of the COI method and leading up to the publication of AS 1680.2.5:1997 a number of different lamps were assessed. At this time no triphosphor lamps or triphosphor based lamps were found to comply. It should also be noted that normal tungsten (incandescent) or tungsten halogen lamps generally do not meet the AS/NZS1680.2.5:1997 criteria although some special high colour temperature or filtered light sources will comply.

Modern lamps use rare earth-based phosphors which provide better colour rendering and provide more light output. Fluorescent lamps commonly in use may not have a continuous spectrum. When selecting lamps for the reliable diagnosis of cyanosis, Hospitals need to ensure that the lamps chosen have a COI of 3.3 or lower, have a colour temperature between 3200K and 5500K and are long lasting and cost effective.

In meeting such strict requirements, the COI compliant Hitachi AAA tube was developed. The Hitachi AAA tube uses a new type of high colour rendering phosphor for the highest CRI of 98 emitting the closest light output to natural light and reproduces all colours accurately. This fluorescent tube is suitable for hospital lighting applications in operating theatres, patient treatment rooms, consultation rooms, accident emergency areas and other areas that require close colour rendition of skin.

Since the research and work carried out based on the publication of AS/NZS 1680.2.5:1997 and prior in 1970, there are now several lamp types available in Australia that meet the COI and colour temperature requirements of AS/NZS 1680.2.5:1997. The Hitachi AAA fluorescent tube has a COI of 3.0, a colour temperature of 5000K and the highest colour rendition index of all lamps currently on the market.

Selection criteria for lamps for clinical observation:

The following selection criteria should be taken into account when selecting lamps for the reliable diagnosis of cyanosis:

  • COI of 3.3 or lower
  • colour temperature between 3300 K and 5300 K
  • lamp price
  • lamp availability
  • lamp life
  • lamp efficacy
  • lumen maintenance
  • lamp range

Moreover, with the continual influx of new technologies and the shift in focus for sustainable, energy efficient products, hospitals are continuing to look to the benefits of COI compliant LED lighting. LED technology has largely progressed and the technical development of LED continues to stride ahead.

Hospitals and healthcare facilities have some of the most rigorous lighting requirements of any setting. Clean, clear and bright light is paramount to all medical staff, whilst warm and welcoming environments can promote tranquillity for patients and visitors and denote safety. Hospital lighting must support the overall integrity of the most general – to the most highly specialised health care environments within the facility.

With such abundant amounts of electricity usage to be exercised, alongside the increasing outward cost pressures, it is paramount that hospitals make use of the benefits of LED lighting and its energy efficiency.

‘Energy efficiency’ entails using less energy to achieve the same level of outcome, or improved level of outcome for the same amount of energy. Improving energy efficiency offers economic benefits as it reduces energy consumption and thus energy expenditure. In an environment of increasing energy prices energy efficiency could stabilise energy expenditure.

Today’s LED lights are also more than 5 times energy efficient than conventional incandescent lights, cut energy use by more than 80 percent and can 10 times longer. The longer service life, reduced maintenance and lower energy requirements of LEDs result in substantial overall savings for any hospital or clinic.

Along with advantages such as energy-efficiency and controllability, the use of LEDs can help facilities managers lower maintenance costs because of their longevity. Hospital staff will spend less time maintaining the lighting and changing bulbs, which in turn potentially reduces the risks of install injuries such as ladder climbing, resulting in fewer accidents and work compensation claims.

Victorian public health services have been implementing energy efficiency initiatives for over ten years. Some of the more common initiatives include:5

  • installing more efficient lighting such as LED
  • installing lighting controls, for example motion sensors in infrequently occupied rooms, such as store rooms
  • installing variable speed drives for fans or pumps
  • installing newer and more efficient air-conditioning plant
  • installing air-conditioning controls such as time controllers that switch equipment off after hours
  • improving the maintenance of building systems.

Hospitals are focused on patient care and the patient experience, and lighting greatly influences the comfort of staff and patients. It is critical to foster environments that protect and promote the health and wellbeing of communities. The health and medical department plays a key role to communicate the importance of the natural and built environments to health and wellbeing of people.

Hitachi AAA Fluorescent Tube

Good lighting helps promote quality and competence within a hospital providing a welcome reassurance for patients. Hitachi recognises this and has designed a fluorescent tube that cares for patients’ health and safety while providing the hospital with optimal light that lasts.

Introducing the Hitachi AAA fluorescent tube with a Cyanosis Observation Index (COI) below the Australian Hospital Standard and the highest Colour Rendition Index (CRI) of all lamps on the market. The Hitachi AAA has been tested, approved and is the recommended fluorescent tube for hospitals.

The Hitachi AAA tube uses a new type of high colour rendering phosphor for the highest CRI of 98 emitting the closest light output to natural light and reproduces all colours faithfully.

The Australian Hospital Standard COI must be below 3.3. The Hitachi AAA tube has 3.0 CRI, that’s better than the Australian Hospital Standard so you can be sure that Hitachi AAA is the best lighting solution possible for your hospital and patients.

The AAA lamp emits absolutely no UV rays and will prevent discoloration and fading of objects and products while also caring for patients and staff in the hospital. ANL Lighting Marketing Manager Stephanie Leung says ‘This makes the Hitachi AAA Fluorescent Tubes the best lighting option for operating theatres, patient treatment rooms, consultation rooms, accident emergency areas and other areas within a hospital that require perfect colour rendition of skin.’

The Hitachi AAA tubes have a long life of 10,000 hours and hold a 1-year warranty that covers lamp failure and fading and is available in two sizes, a 20Watt and 40Watt lamp.

COI has been calculated in accordance with the method described in Appendix G of AS1680.2.5 : 1997.

It's important that medical staff be able to correctly diagnose cyanosis through clinical observation.

A hospital’s number one priority is patient care. An important aspect of medical diagnosis thorough clinical observation is the reliable detection of cyanosis.

Cyanosis is a condition where the skin and mucous membranes give off a bluish discolouration, which indicates that oxygen levels in the blood are dangerously depleted. The ability of medical staff to reliably detect the onset of cyanosis by visual observation may be critical to a patient’s well being.

The detection of cyanosis requires adequate power output around the 660nm wavelength. If the output is too low a patient’s skin colour may appear darker and they may be diagnosed as cyanosed when this is not the case. On the other hand, if the output is too high it may mask the cyanosis and it may not be diagnosed when it is present. The end result is that clinical staff cannot rely on visual detection.

To meet the Australian Hospital Standard and be suitable for detecting cyanosis in hospitals, all lamps must meet two criteria: a Cyanosis Observation Index of less than 3.3 and a colour temperature between 3200K and 5500K. Lamps with colour temperatures above 5500K provide false positive diagnoses of cyanosis and lamps with colour temperatures below 3200K results in failure to detect cyanosis.

Vibe T8-T5 Fluorescent-Converter

Vibe T8-T5 Fluorescent Tube Converter

Next time that fluorescent tube finally flickers and dies, think about this energy saving alternative from VIBE Lighting that could save you 35% in energy costs.

Rather than replacing the inefficient 36W T8 fluorescent tube with another one, VIBE has an eco-friendly convertor kit that allows a thinner, more efficient 28W T5 fluoro tube to be DIY installed in the existing fixture.

This simple retrofit – which can be installed by any home handyman – allows you to maximize your energy savings by using the more energy efficient T5 tube while also saving you the cost of replacing the existing T8 fixture.

The VIBE T8/T5 retrofit convertor kit features electronic ballasts that make stuttering starters redundant, while delivering excellent levels of light stability.

The Australian-approved convertor kits eliminate any flicker or hum commonly associated with tubes equipped with standard magnetic ballasts and have a 25,000 hour life – up to three times longer than the ‘fat’ T8 tubes.

The convertors are available in a variety of wattages matched with tube lengths:

14W – 600mm

21W – 900mm

28W -1200mm

35W -1500mm

There are two choices of VIBE T8/T5 convertor kit which can come with or without an optional high-grade reflector to focus strong, white fluorescent light on the task at hand and help reduce instances of fatigue and eye-strain associated with flickering tubes and dim lighting.

The convertor is easy to install and does not require any re-wiring or modification or any special tools – simply remove the old tube and standard magnetic starter ballast and install the adaptor and lamp.

Where existing fixtures are already equipped with an electronic ballast it must be removed by a registered electrician before the convertor kit can be installed.

Other features of the T8/T5 retro-kit include:

• Triphosphor tubes give full colour spectrum light output

• Higher colour index gives better colour reproduction (CRI of 83)

• High colour temperature for better visual acuity

• High power factor of 96 converts more energy to light

VIBE Lighting says an office replacing 200 conventional tubes with 28W T5 convertor kits could save an estimated $1305 in energy costs and more than 80kg of C02 per year.

VIBE says large users of energy for lighting such as hospitals, schools, offices and retail stores are set to benefit most by retro-fitting the convertor kits.

VIBE Lighting Marketing Co-Ordinator Stephanie Leung: “ There are any number of T5 fluorescent tubes on the market that can be used in the retro-kit. We recommend the 28W Hitachi T5 UV-Cut for its longer 25,000 hour life, its low mercury content of 2.5mg and because it cuts potentially harmful UV rays by up to 75%.”

Hitachi clean tube test

Hitachi Clean Tube Test

Claims by Hitachi that its fluorescent ‘clean’ tubes can result in cleaner air have been verified in an independent test  done in a leading Melbourne hospital.

The Hi-Lumic Clean tubes, which are coated in an optical catalyst film, work to break down organic substances and purify the air whenever they are switched on reducing the  number of volatile organic compounds and bacteria in the  air.

Comprehensive laboratory tests conducted by Korea Testing and Research Institute for Chemical Industry show significant reduction in number of bacteria and elimination of bad odours with Hitachi Clean Lamps.

“We wanted to see if we could replicate a similar result here,” said ANL Lighting Managing Director Eddy Awad.

These claims have been confirmed in a test commissioned by ANL Lighting, the Australian distributors for Hitachi lamps and carried out by Advanced Air Technologies.

Jordan Panayotov for AAT, said: “ In terms of air quality every door is a different story as different pollutants in different concentrations present in the air at specific premises.

“ Having in mind that, for example, there are more than 1000 volatile organic compounds and over 400 species of mould and fungi – the combinations of these pollutants are myriad. On top of this the concrete situation can be very different in different points of time at the same premises.

“ Conducting tests for everything is rather complicated, time consuming and very expensive. Therefore a feasible and cost-effective solution is to measure the total number of particles in the air. For this purpose we use Ultrafine Particle Counter P-Trak product from U.S. company TSI – world leader in air quality monitoring,” he said.

For the test only particles sizes between 1micron to 0.02 micron were measured. For comparison – human red blood cell is 7 micron.

Measuring the number of fine particles in the air in two separate tests (4/7 &  11/7/08) in two separate areas within  the hospital – ground level and level one. Both cases included an inner corridor and adjacent rest room – readings were taken of the ambient air with the Hitachi  Clean tubes and with  conventional fluorescent tubes.

Data obtained in both tests using conventional lamps showed no difference in the number of fine particles in the air between the inner corridor and the adjacent rest room. Repeating the tests using Hitachi ‘Clean’ tubes showed a reduction in the number of fine particles which include  volatile organic compounds and bacteria.

Tests showed that, although that there was difference in the number of fine particles measured in the air in  the two dates (4/7 & 11/7/08), in both dates readings with Hitachi  Clean lamps were down by about 25 % – from 13,800 – 14,200  (conventional tubes) to 10,800 – 11,200 (Hitachi) per cm3 (on 4/7/08);  and from 13,200 – 13,800 (conventional tubes) to 9800 – 10,200 (Hitachi) per  cm3 (on 11/7/08).

Designed to purify the air whenever the lamp is switched on, Hitachi Clean tubes are coated with a thin film of titanium oxide which works to breakdown bacteria and eliminate odours.

As well as breaking down organic substances, the optical catalyst film on the Hitachi tube also reduces smelly odours and smoke in food preparation areas and toilets.

ANL Lighting’s Eddy Awad: The Hitachi ‘clean’ tubes are very effective in not only providing efficient lighting but in all areas where people and business are concerned with reducing bacteria and unpleasant odours, thus  providing cleaner environment.

“ Top of the list are hospitals and aged care facilities, medical rooms, schools and childcare centres – and into the hospitality industry, food industry, supermarkets, dining rooms, clubs,” he said.
