A look at the rapid growth of LED technology

To the everyday consumer, it may seem ridiculous for a product you purchased a year ago to be discontinued the next, replaced by a newer, but not identical model. If we were talking about phones or cars, the answer might be obvious – the result of money hungry corporations eager to sell the next big thing. But, when we’re talking about lighting, specifically LED lighting, it’s a different story altogether.

LED Lighting is an ever-changing, ever-growing market. Since 2016, demand for more energy efficient lighting from climate conscious consumers has driven this growth, as has government lighting regulations and laws. Since LED was first introduced, the price of production has reduced immensely, and manufacturers have begun to find new ways to improve its implementation and applications.

For you, the consumer, this means that something you buy today may be impossible to get in a years’ time.

More than just a gimmick

According to market research reports, the global LED lighting market size is projected to reach $54.28 Billion by the end of 2022, with a compound annual growth rate of 13% from 2017. While this is just a projection, there’s no denying that LED has quickly proven itself the future of lighting.

The main driving force behind this growth is the advantages LED Lighting has over incandescent and florescent technologies, and the environmental benefits it offers. LED consumes drastically less energy than both incandescent and florescent lights, making it more energy efficient, better for the environment, and cheaper for the consumer to run.

As a result, environmentally conscience government bodies around the world have been pushing for the uptake of LED within households and commercial properties. An example of this push can be seen within Australia, where government energy Incentive schemes are encouraging businesses to upgrade to LED through lighting subsidies:  The VEU in Victoria, ESS in New South Wales and REES in South Australia.

In hand with these new subsidies, a string of new lighting regulations and laws surrounding lighting technology has driven the growth of the LED sector. Measures to phase out Incandescent bulbs has been the biggest of these changes – with bans on both the manufacturing and sale of these bulbs since the late 2000s meaning that alternatives such as compact fluorescents and LEDs have become the new norm.

Smart Lighting – Not just for retrofitting

As the LED market is projected to grow a significant amount between now and 2022, one of the biggest segments of that growth will be Smart LED Lighting – estimated to grow from $7.93 Billion in 2018 to $20.98 Billion by 2023.

While in the beginning LED lighting was primarily targeting the retrofit market, that is, replacing existing lights, new innovations in connectivity and smart technology such as Wi-Fi, Bluetooth and LPWAN have revealed its true potential.

Smart Lighting uses a Wi-Fi network to allow light bulbs to talk to each other, enabling the user to control them through other networked devices such as their phones and laptops. This technology is linked to the growth of the larger ‘smart home’ technology market, which allows everything from lights to televisions to be connected through a central hub.


Innovating on what we already know

Smart lighting isn’t the only way LED lighting is changing the lighting industry. Products such as the Tri-Colour Downlights are innovating on the typical downlight design, offering a replacement to the older MR16 and GU10 technology. Highbay lighting has seen a massive shift from the previously standard High Intensity Discharge Lamps, to LED UFO highbays, which not only improve the lighting of warehouses, but the safety of the space as well.

What this means for you

So, LED lighting is a fast-changing technology, how does this impact you, the consumer? The simple answer is this – as LED technology changes rapidly every year, the products you can buy today may be impossible to get in a year. While there’s often a newer version on the market as a replacement, these aren’t always identical in design or look – or even price.

Luckily, LED lasts a long time, so the chances you’ll need to upgrade immediately are slim. This is one of the biggest benefits of the technology – it’s longevity.

That being said, if you’re concerned about not being able to acquire the same product again, especially in the case of commercial applications, buying extras to keep on hand is the best way to ensure you can replace or upgrade old bulbs quickly.

A look at Ultraviolet Lights

Ultraviolet Lamps encompass a range of lights that produce Ultraviolet light. As these lights are used in many unrelated industries and applications, with many variables in their output, we’ve created a one-stop guide for helping you identify the best UV Lamp for you.

What is Ultraviolet?

UV is a light radiation produced by the sun, and you may know of it due to classic Australian ads that talk of its dangers to our skin. Invisible to the human eye, UV travels on a wavelength between visible light and x-rays.

Ultraviolet ranges:

The most important thing to understand when buying UV lamps is the differentiation between the UV subtypes. As ultraviolet light is on a spectrum, it has levels of intensity based off its wavelength. The shorter the wavelength, the more dangerous it is for humans – because while the earth’s atmosphere protects us from all but the long wave UV light, some lamps are made to produce a type that is extremely harmful to the eyes and skin, and shouldn’t be used unless by a professional.

Just knowing the below will help you identify if it’s the right light for you.

UVA:  Longwave ultraviolet light, most commonly known as blacklight or blacklight blue in the lighting industry. These lights often use a filter material which makes the bulb appear violet. UVA is the safest of the UV spectrum.

UVB: Medium-wave, UVB is often used for reptile lights, and speciality tanning lamps.

UVC: Shortwave UV, and the most dangerous of the UV subtypes. Used for what is known as germicidal lamps, UVC disrupts DNA and can be used for a range of specialised applications, especially in sterilisation and water purification.

Lamp types:

Blacklight and Blacklight blue:

The most recognisable form of UV lighting, Black light and Black light Blue (BL and BLB) can be distinguished by the colour they emit.

Black Light Blue shines as a violet, purple colour, made due to the filter material of the bulb’s glass. Known as Woods glass, these appear almost black when unlit, filtering out most visible light. While not bright, BLB triggers a fluorescence in other colours, causing them to glow. This effect can be useful in a wide variety of applications, including medicine, forensics, detection of counterfeit money, and of course for decorative purposes in nightclubs.

Blacklight on the other hand ironically produces a bluer colour than Black Light Blue, and is often used in bug zappers and insect traps. This is due to insect’s ability to see UV light, attracting them. These lights don’t produce the fluorescence that BLB does, so make sure that the UV lamp you’re buying is dark in appearance and tagged with “BLB” if you require that effect.

Blacklight and black light blue lamps come in two core types: Fluorescent and Mercury Vapor. Below, we’ll go over the difference.



Normal fluorescent lamps produce light by sending an electric current through a tube containing argon and a small amount of mercury vapor. When the mercury vapours are excited, they produce UV light, which in turn causes the coating of the lamp to fluoresce or glow.

Fluorescent black light lamps work similarly, but use a phosphor on the inner tube surface which emits UVA radiation instead of visible light, and the dark blue filter coating over the tube.

As Fluorescent lamps already naturally produce more UV than any other light, they are well suited to the BLB and BL applications, and much more effective than incandescent BL and BLB lamps.


Mercury Vapor:

Mercury Vapor BLBs are most commonly used in clubs, concerts, and other large displays where the aim is to create a particular aesthetic through the fluorescent glow caused by the UV, aka the “glow in the dark” effect. Mercury vapor lamps are the most efficient producers of UVA, even more so then fluorescent tubes.


Germicidal Lamps:

While these may look like ordinary tubes, Germicidal Lamps produce the far stronger UVC. They do not have the phosphor coating of BL or BLB, as this absorbs UVC. These tubes have nearly triple the UV output of ordinary fluorescent lamps.

As previously mentioned, this UV type is the most dangerous to come into contact with, and can cause temporary or even permanent blindness and skin conditions if mishandled. For this reason, germicidal lamps are used primarily for specialised areas.

The most common of these is in Ultraviolet germicidal irradiation (UVGI). This is a method of disinfection that uses UVC to break down and destroy bacteria and other microorganisms at a cellular level. You may see now why it can be so harmful to humans as well. Most often used to purify drinking water, as well as medical equipment and even food.

Industrial Lighting Upgrades: Why you should go to LED

While the switch from traditional highbays to LED highbay lighting may seem like the obvious choice, many are still sitting on the fence when it comes to making the upgrade.

Industrial spaces such as warehouses, factories, and manufacturing facilities traditionally use older technology such as metal halides for their lighting requirements. When the time comes to replace a lamp, more than a few businesses will opt to simply replace old technology with old.

This is the easy choice, and perhaps the short-term savings choice – but not the most commercial option. While biting the bullet to upgrade to a high-quality circular LED highbay may seem like a large investment, the long-term savings and benefits are not to be overlooked.

Long life and better lumen:

New LED Highbays last up to 50,000 hrs vs a metal halide’s 11,000, and this doesn’t just affect the time to needing replacement.

While a conventional highbay will significantly reduce in lumen output as time goes on, new LED highbay’s will keep 95% of their initial brightness up until obsolescence. This more than makes up for the lumen reduction one will see in HID vs LED discussions.

Not only that, but every year LED technology improves, increasing the lumen output while keeping wattage low – and keeping the lights even more compact. Take the Deluxlite UFO Highbay as an example, it reaches up to 19,500lm while operating at just 150W!

Safety and better working conditions:

Metal halide lights, a type of HID (high intensity discharge) light, have a dangerous history of overheating and exploding from high pressure. While this is usually an end of life behavior – halides can fail and explode, even when new. This presents a risk not only to employees but the entire facility. Exploding lights can lead to fire and property damage.

Circular LED highbay lights mitigate this risk as they do not run hot, nor do they have a history of issues like the metal halide.

They also produce a better-quality lumen, and can be easily adjusted to point towards workstations and other areas where a concentration of light will benefit employees.

Save energy and money:

Industrial spaces like warehouses, factories, and manufacturing facilities are known for their high electricity bills and the detrimental carbon footprint they produce. Replacing old halides with LED Highbays will quickly help with both the presented issues.

LED’s produce far less heat and UV, use up to 70% less energy than a HID light, and last longer. Less replacement’s means less carbon produced in their manufacturing – and a lower electricity bill for you.

So, LED Highbays or Corn Lights?

Now that we’ve gone over the benefits of LED over traditional lighting, it begs the question of which LED replacement to choose. We’ve used circular LED highbays in our previous examples, but it’s not the only option for those looking to change.

Corn Lights:

Corn lights are the retrofit replacement for old HID systems such as metal halides and high-pressure sodium lamps.

These ‘corn-shaped’ lamps are a power-saving LED alternative to traditional bulbs. Coming in a range of lumens, sizes and voltages, there’s sure to be one that will fit your needs.


Replacing your old HID bulbs with these will still require some rewiring, however, you will be able to keep the same reflector setup as your traditional highbay’s, and once done it will be as simple as getting a new corn light should one (rarely) fail.

Like all LEDs, they are energy saving, environmentally friendly, and long life – up to 50,000 hours, although you may find some brands are lower in lumen than your traditional lights.

Don’t worry too much, though, as explained in our LED blog, LED lumen will not degrade like older globes, so the later in life output will be better than what you’ve had previously.

Circular UFO LED Highbays:

Unlike corn lights, which replace the bulb, a UFO LED Highbay light is a direct switch out from your metal halide or other HID setup. Comparable in shape to a ‘UFO’, these lights have a wide beam angle and high lumen output.


The fittings for your HID will be replaced with the new highbay, requiring more time to change out compared to a corn light. The wide angle of the light beam may not be suitable for aisles, and in changing from your metal halide setup, more consideration with have to be taken for placements.

If you don’t require a directional light, then the UFO option is a great way to reduce dark spots in your lighting.


It isn’t exactly the contest of one being strictly better than the other. All setups require consideration and review of what could best be applied. In the end, both options will see you savings on energy bills and long term maintenance costs, along with the other benefits of LED lighting.

If you’re still not sure of what to choose, it’s best to speak to either your electrician, or give our great team at Lightonline a call on 03 9819 1777.

DIY Replacement LED downlights – Points to Remember

Right, you are now ready to install your LED downlight yourself. Interesting fact is still many folks opt for halogen or compact fluorescent downlights, however we must consider LED downlights consumes less power as compares to other fixtures and thus would make one save on the power bills. Another benefit that is making those go green initiatives take a new shape is that LED fixtures do not emit anything that is harsh on the environment, no rays, no heat and no toxic elements. Also, LED downlights are a better option than other lighting as they are designed to last.

Different downlight fixing optionsGE spring based downlight fixture DIY

We stock different downlight fixture options such as

  • In a downlight with spring clips
  • In a downlight with twist front face plate/ flexible push in clips
  • In a downlight where the face plate comes off

Few points to remember before start replacing your LED Downlights

  • Always switch off power supply before commencing work.
  • Operating temperature range of the lamp should be between -20°C and 45°C ambient. Over-heating can affect lamp performance.
  • Only use in indoor applications and in open fixtures providing 10mm free air space.
  • Ensure the fixture has the appropriate lamp-holder.
  • Do not use or install the lamp in highly dusty or smoky environments. It is recommended that you install the lamp only after construction is completed.
  • Input voltage should be +/-10% the amount stipulated in the specifications.
  • If LED lamps are dimmable with compatible mix of transformers and dimmers, actual dimming performance depends on dimmer type (refer to the recommended dimmer & transformer list). Please note the different combinations based on the type of lamp and number of lamps.
  • Not intended to use with emergency light fixtures or exit lights or DC transformers.
  • Customer may notice a one second flicker during star tup. This is normal and will not affect lamp performance and lifetime.
  • Relative humidity in the installation should not exceed 80% Relative Humidity. Do not install in bathrooms, kitchens and wet areas. These lamps have no tolerance to water.
  • Lamps must be protected from the ingress of salt air.
  • Do not install the lamp close to medical equipment/televisions/studios/radio areas.
  • Certain lamps include a fan to assist performance. Noise might be audible in silent environment. (Applicable only to a range of dimmable lamps)
  • Products are not subjected to more than total of 20,000 fast switches (time between “on” and “off” should be less than 10 minutes).
  • Electrical installation in which the product operates must not be subjected to voltage fluctuations. The mains supply should have surge or over voltage protection equipment.
  • It is also recommended that all lamps on one transformer share the same brand.

How about installing the downlights

LED Lighting compared with Fluorescent Lamps

LED lighting is truly the next generation technology which features various benefits to not only buyers for Home LED Lighting, but companies also, with LED Downlight products and LED Tubes which can replace out-dated, flickering fluorescent lighting. LED lighting allows such benefits as a higher energy efficiency than CFLs and fluorescents, lower power consumption, lower maintenance costs, longer lifetime, durability and brighter light output than traditional fluorescent lighting. LED lighting is slowly filling the Home Lighting and Business Lighting marketplace with such innovative products as LED T5 and LED T8 Tubes, Flexible LED Lighting and LED Downlights.

Fluorescent lighting contains toxic materials such as mercury which is harmful to environment and human body. Did you know that if you drop or break a fluorescent bulb you must leave the room for 4 hours, due to the toxic materials floating in the air, which could cause respiratory damage, or Asthma in the long run for workers who have to deal with these fixtures regularly. For workers and personnel who replace fluorescent tubes at work such as electricians are the most impressed by LED tubes, since they are not only easier to install, requiring no ballast, but they are worry-free, as they can last upwards of 10 years, on for 24 hours a day, and do not contain any toxic materials like mercury dust that fluorescents do. For quick installation, LED tube lighting can be placed and installed directly into existing fluorescent T5 and T8 sized sockets, you only need to remove the ballast, plug the LED bulbs in, and you’re done! Contrary to popular belief, LEDs are very easy to install in this day and age, and the most LED products are now “plug-and-play” while still offering a slick look with unmatched energy savings.

Although fluorescent lighting is more energy efficient than incandescent lighting, it is still an energy wasting monster when compared with LED lighting. For businesses who have a large electric bill, switching to LEDs could cut your energy bill in half, while still keeping all of the brightness, and no fluorescent flickering! Even with the most advanced state of the art CFLs, fluorescent lighting accounts for a high percentage in existing lighting all over the world, switching from fluorescent lighting into LED lighting can greatly reduce the global lighting power consumption and greenhouse gas emissions. Now let’s do some detailed analysis to compare LED and fluorescent lighting, and there is no doubt that LED will defeat fluorescent lighting.

Replace your fluorescent lighting with energy efficient LED TubesIn contrast, LED lighting is solid-state lighting which does not contain any filaments that could break or hazardous materials like CFLs. The upfront costs of LED lighting are too high, due to the technology used to achieve such a high lumens per watt rating, it is true. However, think about the long-term energy conservation, and savings you will get from not needing to replace the lights, for up to 5 or 10 times as long, depending if the light replaced was incandescent or fluorescent. Either way, the more high-energy halogen, incandescent, or fluorescent lights you replace, the more money you will save every month. Check with your state, half the bill could be on them due to recent energy grants and programs set up by Government energy policies introduced in early 2010. Over the full life of the LED tube or bulb, the money saved by using LED lighting will be tremendous. When factoring in the true price of lighting, you must include all three variables such as Initial investments, maintenance expenses, and a maintenance to routinely replacing lights.
