Dispelling the myths surround LED lighting technology
By Reggie Nxumalo, GM, Philips Lighting Southern Africa
As with many other industries, the ebb and flow of technological advancement has resulted in the lighting industry undergoing significant change over the last few years. One of the most important of these technological developments has been LED technology, which has allowed for a range of benefits to lighting applications such as longer lifespan, lower carbon emissions, enhanced efficiency as well as a marked improvement in the quality of light. This has ultimately culminated in LED lighting systems obtaining an ever-growing market share.
However, even though more and more people appreciate the benefits of LED lighting, there are still stories and misunderstandings going around surrounding the technology. This article aims to shed light on the most common myths in order to provide a clearer picture of how LEDs can work you’re your business or home.
LEDs last forever but are not bright enough
Compared to the average light bulb, LED bulbs do last a lot longer. However, they won’t last forever. Like all light sources, they eventually fade over time. But remember that Philips’ LED light bulbs will keep shining almost as brightly as they did when new for most of their lifetime. Many other brands start to noticeably fade – even after just a year of use.
When it comes to brightness, LED bulbs emit the same amount of light as traditional light bulbs, energy saving sticks as well as twisters. In fact, many outdoor roads, tunnels, entire building facades, indoor offices and shop floors are entirely lit using LED lighting today. The main difference is that they use far less energy.
For example, a 7W Philips LED bulb is just as bright as a 60W traditional light bulb or a 12W energy saving stick. You can choose a LED light that shines with the familiar warm glow of a traditional lightbulb, or go for one that closely mimics natural light. There’s a LED light for every need in your home or office.
LEDs don’t get hot but their price makes you hot under the collar
LEDs do emit heat, but much less than energy-saving sticks, twisters or conventional light bulbs. Just as importantly, when used in your light fittings at home, LEDs don’t emit infrared (IR), only visible light. You can’t see IR, so it doesn’t add to the brightness of the light. Instead, IR just makes bulbs hotter and wastes energy. Another plus point is that LEDs don’t emit ultraviolet (UV) light either.
In the early days of LED, pricing used to be the biggest hurdle to the widespread adoption of LED lighting systems, but this quickly changed as a result of increased competition amongst manufacturers along with decreased production costs.
While the initial investment in LED systems is higher than that of conventional systems, the return on investment for the use of these systems is surprisingly rapid, especially when taking maintenance and energy costs into consideration. Due to the long life of the LED, no replacement is required for a long while, and users can expect an energy saving in the region of 50% to 70% compared to traditional lighting systems. Economic payback, then, can be experienced within less than two years.
LED light quality is poor and LEDs have problems switching rapidly
There are several measures that are used to describe light. For instance, colour temperature characterises the colour appearance of a source and describes the apparent warmth or coolness of that light source.
The colour rendering index (CRI) on the other hand, is a metric used to measure the quality of light. The CRI for many white light LED systems is typically between 70 and 85 (out of 100), and continues to improve rapidly, making it suitable for nearly all lighting applications. CRI is currently the prevalent method for judging light quality.
On the topic of switching rapidly, LEDs are capable of reaching their full output almost instantly after switching on. Moreover, these lighting systems can be switched continuously, without shortening the useful life.
3W LEDs are brighter than 1W LEDs and LEDs are not resistant to vibration
Not necessarily! In the past, original equipment manufacturers relied on wattage to give an idea of the brightness of a traditional bulb. But the number of watts (W) is just a measure of the power the bulb consumes. With LEDs, the number of watts does not tell you about brightness. Two different LEDs can consume the same power, but differ noticeably in light output.
When selecting LED bulbs, it’s better to look at light output instead of power. The light output of a bulb is measured in a unit called lumens (lm), and this is indicated on the packaging. In addition, Philips also shows the wattage of an equivalent traditional incandescent bulb that would give the same light output, because buyers are still more familiar with this measurement.
On vibration, there are no moving parts, filaments or fragile glass used in LED bulbs, so they are very robust. The Philips LED products all pass vibration tests according to internationally agreed standards (IEC), and in some cases, we use even tougher military standards to make sure our LEDs are going to last.
Hopefully, this article has managed to debunk some of the LED myths. In the end, figuring out the ROI for using these lighting systems at your home or business will come down to a range of considerations that include energy usage, maintenance costs, lifespan of the systems, colour quality, colour consistency as well as making the best of the available technology.
LED lighting myths decoded – Part 2
By Reggie Nxumalo, GM, Philips Lighting Southern Africa
Over the course of the last decade, LEDs has become popular lighting solutions because of its energy efficiency, the long-life of the light source, as well as its increasingly affordable. In more and more applications, this established technology is now the lighting of choice. Moreover, it is also lighting up the path towards the future of lighting that is based on the next generation of light-emitting diodes: OLED.
However, even though more and more people appreciate the benefits of LED lighting, there are still stories and misunderstandings going around surrounding the technology. This series of articles aims to shed light on the most common myths in order to provide a clearer picture of how LEDs can work you’re your business or home.
LEDs need time to warm up and can’t be dimmed and controlled
LEDs do not require any time to warm up. Unlike fluorescent lamps and energy-saving twisters that come on slowly and my even flicker, LEDs shine with their full light output almost instantly after switching them on. They can also be switched on and off continuously, without shortening their lifespan.
LEDs can also be dimmed and controlled, as these lights are digital, which basically means they are either on or off. To dim them, they are switched on and off very rapidly (faster than the eye can see), so they can be controlled. However not all LED light-bulbs are designed to dim, so if you want to use a dimmer, then you must choose the lamps that show that they can be dimmed. Look for the dimmable logo on packs. In many cases, you can use your existing dimmer switches. Just remove your current lamp and replace it with a dimmable LED lamp.
LEDs don’t work in extremely cold environments & shine with a very white light
LEDs actually become more efficient and last even longer when used in cold temperatures. Excessively high temperatures can shorten the life of electrical and electronic components (which is partly why traditional incandescent lamps don’t last very long), so running a LED lamp in even the coldest climate is not an issue.
The first LED bulbs were very white, as this was the most effective way to use them. However, today they are also available in an array of ‘shades of white’ ranging from warm yellow through to cool blue. Look for the ‘shade of white’ indication on the packaging.
LEDs contain hazardous substances and are harmful to the eyes
LEDs do not contain mercury, lead or other toxic materials and are completely recyclable just like most other electronic devices.
LED lights LED lights are as safe to the eyes as any other artificial light source. They are not like lasers, the light is not focused to a single point, and the intensity is comparable to traditional bulbs and halogen lamps.
LED lights affects Circadian Rhythm Cycle
The human body utilised light cues such as those provided by the sun, to time its internal functions. These light cues regulate mood, sleep, energy, appetite, as well as digestion. These daily internal cycles are called Circadian rhythms.
These rhythms are stimulated by our eyes’ photoreceptor cells, as they measure the blue light spectrum in the light. Although there is a small amount of blue light present in LEDs that are used for general purpose, this is a tiny fraction of the emissions when compared to natural day light.
So in short, a LED luminaire designed for general lighting applications does not have enough blue light spectrum to stimulate photoreceptor cells in our eyes, thus it cannot influence our Circadian rhythm.
Hopefully this article series has managed to debunk many of the LED myths.
In the end, deciding on the perfect lighting solutions for your home or office will come down to a range of considerations that include energy usage, maintenance costs, lifespan of the systems, colour quality, colour consistency as well as making the best of the available technology.
