ABOUT LED LIGHTS

CITY OF SYDNEY MOVES TO LED LIGHTING

WHAT IS LED LIGHTING

Unlike incandescent lamps, which use a filament or fluorescent, which uses a gas filled tube, an LED (light emitting diode) is a semiconductor or solid state light source. Appearing as practical electronic components in 1962, early LED’s emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness and efficiency. Light-emitting diodes are used in applications as diverse as aviation lighting, automotive lighting, advertising, general lighting, and traffic signals. LED’s have allowed new text, video displays, and sensors to be developed, while their high switching rates are also useful in advanced communications technology

CREE-chip

Recent advances in LED technology have produced LED lights that compare in quality and brightness to many traditional lights, such as Halogen Downlights and Incandescent Bulbs. LED lights are currently more expensive than traditional lights, but considering they can last 20 times longer, use 5 times less energy and are far better for the environment, it seems there popularity will continue to grow and there cost decrease 

REDUCE YOUR LIGHTING COST

LED lights use over 80% less energy than conventional incandescent lights and 60% less than compact fluorescent tubes. An investment in LED lighting will usually pay for itself in less than 2 years for an average business or household and you receive all the benefits of healthier lighting and helping the environment from day one

The table below illustrates an estimate of the cost saving benefits by using 10w LED lighting for a period of 24 months compared to traditional 50w Halogen lighting. These calculations assume a typical 3 bedroom house or commercial property with 25 x 50w equivalent Downlights

ADDITIONAL BENEFITS

  • Changing to LED lights not only saves you money by using less energy but you also contribute to a cleaner and healthier environment
  • LED Lights last much longer and need less maintenance, saving you time and money
  • LED lights help you achieve a 7 STAR Home Energy Efficiency Rating and also help to meet BASIX standards for efficiency in new homes
  • LED lights produce 65% less heat than conventional halogen globes, reducing work for air conditioners and reducing your power consumption

HELP YOUR ENVIRONMENT

The evolution of LED technology will change the way we look at illuminating our world forever. Eco friendly motivation is an increasing factor in today’s society. Most of us make conscious attempts to take advantage of new and emerging technology to reduce our energy consumption, therefore reducing our negative impact on the environment. Researchers are making incredible advances in more energy efficient and longer lasting devices. LED technology advancement is a prime example of our growing need to improve our environment, its  incredibly efficient, healthier and fully recyclable

LED technology has many environmental benefits
  • Traditional filament based lamps (Incandescent) and even newer compact fluorescent (CFL) contain toxic chemicals such as tungsten and mercury which makes them hazardous to recycle. LED lights contain no toxic materials and are fully recyclable
  • Unlike incandescent lamps , LED light produce no harmful UV radiation and will not fade fabrics or works of art and are much healthier to work under
  • Due to LED’s low power consumption, 80% less than incandescence’s, they create far less carbon emission, which is great news for the environment
  • LED’s lights generate far less heat and are reasonably safe to touch, even when left on for long periods. They dramatically reduce the chance of fire and heat related problems and are particularity safe with young children around
  • LED tubes are now available to replace existing fluorescent tubes. Existing florescent tubes can cause discomfort and headaches for some people
  • LED lights work at a different frequency than traditional lighting and therefore do not attract insects

WATTAGE

A Watt is the amount of power or energy that a light will consume. LED lighting produces more lumen per watt than traditional incandescent lamps and this is the main reason that LED lighting can save you money, same amount of light for less energy consumption

BRIGHTNESS

Brightness is measured in lux and lumen’s and is a common and easy way to evaluate LED lighting. However, lux and lumen are only two of many characteristics that determine quality and suitability to suit an environment. The temperature of the light is critical to evaluate brightness. For example, a 6w LED light in a cool white temperature will have more lumen than a 6w LED light in a warm temperature. A light with a smaller angle will have a greater brightness than a light with a wider angle due to the photon concentration in a smaller, tighter beam

LUMEN

Lumen is the total amount of light a lamp will produce. Much of the light from traditional lamps, such as Halogen, is wasted energy as its directed away from where its required such as back into a roof cavity. LED lights have far more directional focus and are therefore more efficient and achieve about the same lumen as traditional incandescent

LUX

Lux is the concentration of light on a particular point at a particular distance from the light source. One Lux is equal to one lumen per square meter and since the light area increases with the distance from the source, Lux is given at a particular distance. Lights with a smaller beam angle will achieve a greater Lux

COLOUR TEMPERATURE (CCT)

Considering the colour temperature of lighting is important when determining the warmth and ambiance for living, working and commercial areas. For example, a warmer light is often used in public areas to promote relaxation, while a cooler light is used to enhance concentration in offices and work spaces. Colour temperature is rated in Kelvin (K). Color temperatures over 5,000K are cool colours and appear blueish white, while lower color temperatures 2,700–3,000K are warm colours and appear yellowish white through red

      • 1200k  candle light
      • 2700k  light bulb
      • 2800k  halogen lamp
      • 4000k  fluorescent lamp
      • 5000k  flash light (camera)
      • 5600k  day light

The colour temperature control of LED lighting has advanced dramatically over the last ten years. LED lighting is now superior to traditional lighting and is available in several colour ranges to suit application

LED Warm White light

LED Warm White – 2700K Typically used in a warm relaxed atmosphere like lounges and bedrooms

LED Neutral White

LED Neutral White – 4000K Typically used in a working atmosphere  like kitchens, bathrooms and entertainment area

LED Cool White

LED Cool White – 5000K – 6000K Typically used in a professional atmosphere like shops, offices and commercial space

CRI (colour render index)

CRI or colour rendering index is the lights ability to reproduce the colours of various objects in comparison to natural light. The higher the CRI range the more accurately the colours of objects will be reproduced. CRI ranges from 0 – 100 and generally, LED lighting ranges from 70 to 90. The amazing Brightgreen D900 Curve, is particularly accurate at a CRI of 95+

BEAM ANGLE

Beam angle determines the spread of light from a single source. Most LED lamps will have a spread of at least 15 ° and some up to 120 °. It is important to consider the beam angle when choosing your LED lighting. One high wattage lamp with an angle of 100° can provide the same light coverage as 4 lower wattage lamps with an angle of 60 °

LED DRIVERS

All of our LED products work in the 220-240 volt or 12 volt range. 12 volt MR16 Spotlights require a separate 12 volt driver/transformer to power the LED. The driver changes 240v down to 12v and in most cases are installed in the roof or wall cavity. Our 12v Spotlights are carefully selected to be compatible with the majority of new drivers and those that are currently used with old Halogen lights

On rare occasion, LED replacement lamps may not be compatible with your existing drivers. If you find that your new LED lights flicker, randomly turn off, don’t turn on with full brightness or buzz, then your old drivers may not be suitable. If you find that this is the case, we can recommend a compatible low cost driver to match your new lights – Please call us to discuss requirements

If your unsure of your driver compatibility, then you may like to consider our Downlights. These are supplied with the lamp, stylish fascia fitting and matched LED driver.  Click here for our LED Downlights

We recommend that all 240 volt installation work is carried out by a licensed electrician
