What does LED stand for?

Light Emitting Diodes

 

Why is LED Lighting the next generation of lighting?

LED lamps are the next generation of lighting that save energy, reduce maintenance and replacement costs and help protect the environment. They also last much longer than traditional lighting.

 

What type of light quality can I expect with LED lights?

LED lamps can match your existing lighting in terms of brightness and colour. But, as with any product, there can be poor quality and high quality LED lamps. You may have had experience with poor quality products already that do not match your existing lighting. This website will help you select the correct lamp to replace your existing lighting in terms of brightness and colour.

 

How energy-efficient are LED lamps?

LED lighting can save up to 90% of the electricity used by incandescent and halogen lamps and up to 50% of electricity used by fluorescents lamps.

 

Where are LED lights being used?

LED lamps are being used where the lighting is on for a long time such as hotels, restaurants, shops, factories, and homes.

 

Is LED lighting better than incandescent or halogen lighting?

Around 80-90% of the energy emitted from incandescent bulbs is converted to heat instead of light.

 

LED lighting is about 85% more efficient than incandescent lamps and hence do not need as much energy to product the same amount of light.

 

LED lights are also designed to last about 50 times longer than incandescent lighting.

 

What is the best, LEDs, fluorescents or CFLs?

Unlike LED lamps, most fluorescent lights and CFLs harbor hazardous materials, such as mercury. This requires their careful and proper disposal, ensuring that they do not contaminate landfill sites.

 

As most cannot be dimmed, Fluorescent lights may suffer from flickering. Unfortunately, people can be sensitive to this effect – resulting in eye-strain, migraines and other head-aches. LLED lamps utilize solid- state technology enabling stable dimming with no flickering.

 

Fluorescent lights may take noticeable time to reach optimum brightness, a problem that is compounded in cold conditions. LED lights are instant-on in any environment – even inside cold rooms and freezers.

 

How long can LED lamps last?

Good quality LED lamps can have a lifetime of 50,000 hours or more but the average is around 35,000 hours. But this all depends on their design and how they dissipate heat from the LED chip. Depending on how many hours they are used a day, that can last as long as 20 years.

 

Unlike other lighting products LED lamps do not completely fail – they get dimmer. At 50,000 hours of use (or their rated lifetime), an LED lamp will be designed to provide at least 70% of its initial light output (LOR). The lifetime is dependent on many different factors including lamp design, LED chip type, ambient temperatures and fixture design.

 

Actual life of an LED is complicated to calculate and should be based on LM-80 measurements (calculated by independent testing labs) of the LED sources. Well-designed LED lamps try to get the optimum balance between light output and longevity.

 

Aren’t LED lights too expensive?

The upfront cost of LED lamps do cost more than conventional lamps but they save a lot of costs over time from reduced energy usage, replacement and maintenance costs.

 

But how do you define expensive? Is it the up-front cost or is it the running cost of the lamp over time or the cost to change the lamp once it has failed?

 

If it is a new building, installing LED lighting is sometimes the same cost as traditional technology which means you will start to save from the word go.

 

Can LED lighting really save energy and money?

Figures released by the U.S Department of Energy estimate that embracing LED lighting on a large-scale by 2025 will:

 

    • See a 62% reduction in energy usage.

    • Result in 258 million metric tons of carbon emissions wiped out. Reduce the amount of materials being put into landfills land fill. No need to

       build 133 new power plants.

    • Overall it would save the US over $280 billion.
