FAQs

Q?

Are LEDs safer option than CFLs?

A.

CFLs contain mercury which is highly toxic. It poses immediate threat if CFL is broken and they have to be handled as hazardous waste. LED’s do not contain either mercury or lead, thus there is no threat if they are broken and can be disposed of in normal landfill without any threat to environment.

Q?

What is LED?

A.

LED is a diode that emits light when powered. These are known as Light Emitting Diodes. You may have come across LEDs in the form of tiny round or rectangular indicator lamps used in electronic and other equipment. Recent developments in LED technology make the use of LEDs for lighting a highly efficient, very promising and environment-friendly option.

LED lamps employ light-emitting diodes (LEDs) as the source of light. LED lamps have a long service life and are highly energy efficient. In recent years, with improvements in LED technology; light-emitting diodes with higher lumen output are making it possible to replace other type of lamps with LED lamps.

Q?

What is LED Lighting?

A.

The advent of high brightness LEDs opened the doors to use of LEDs for lighting applications. It is a solid-state technology. This means there is no glass bulb, no pressurized gases, no mercury and no burning filament. In the traditional bulb, heat was the main result while light stood as a mere by-product of electrifying the filament.

Q?

What are the advantages of using LEDs over traditional incandescent lighting?

A.

LEDs use just about 1/8th of electricity an incandescent lamp uses. LEDs typically last about 50,000 hours which translates into 17 years of life span if used 8 hours a day. They are also smaller and do not contain any dangerous chemicals like mercury. They can readily be put in places that have always been too small or out-of-the-way for many incandescent lights, as well as in places that were always very dangerous or difficult to get to. The bottom line is that LED’s are easier and safer to use than all previous lighting technologies. Plus, LEDs will save you money by consuming less power, lasting much longer, and generating much less heat, which in turn combine to result in lower climate control costs.

Q?

How widespread is the use of LED lighting?

A.

Architects and lighting designers are specifying entire lighting packages in their new designs. Contractors are using them in everything from custom kitchens to retail stores. Many homeowners are replacing their incandescent/fluorescent with LED bulbs. LED lighting can replace every aspect of old lighting technology; as well create entirely new lighting applications due to its versatility. Your imagination is its only limitation.

Q?

What are the colour options available in LED lighting?

A.

Q?

Do I need to change my existing lighting fixtures?

A.

As of February 2007 Australian government has passed a law which has seen the phasing out of incandescent bulbs by 2010. The other alternative given to replace the lighting fixtures were the compact fluorescent bulbs. These bulbs contain hazardous levels of mercury whereas LEDs do not carry any such materials. LED’s are by far the safer and cleaner option. Many people are using LEDs and compact fluorescent lights (CFLs) in a bid to shrink their carbon footprint. Be it household lighting, commercial, work or leisure. Switching from traditional products, LED is an effective, accessible change every person can make right now to reduce energy use and prevent green house gas emissions that contribute to global warming.

Q?

Do LEDs require separate compatible drivers?

A.

LED’s require constant current or voltage to operate optimally. LED drivers are made to do just that as opposed to existing halogen transformers. The only exceptions are the Edison screw (E27) and Bayonet Cap (B22) have inbuilt drivers and can be used as is.

Q?

Why should I choose LEDs?

A.

The LED’s are superior choice over other lighting products because:

  • They use very little energy as compared to other lighting sources. LED’s are nearly 8 times more efficient than heat producing, power hungry halogen globes.
  • LEDs last 5 to 10 times longer than compact florescent globes.
  • LED’s last up to or longer than 50000 hrs. This advantage eliminates the need for periodic change of bulbs which involve money and cost of maintenance.
  • LEDs produce very little heat which reduces the strain on air-conditioning and saves on that cost.
  • Use of LEDs decreases fire hazard as they do not produce the same heat as halogens
  • They are safe from harmful chemicals like mercury and lead which can be hazardous to both human and environmental health.
  • LED light bulbs are less sensitive to shock, vibration, and the extreme temperature changes that can quickly ruin a fragile halogen bulb. Fluorescent bulbs wear out much faster if they are frequently turned on and off. LED bulbs are not affected by frequent on-off switching.

Q?

What are the considerations one needs to look into while choosing LED lights?

A.

Colour

It depends on your personal taste and the area that will be illuminated. Colour is often represented by temperature in Kelvin. A low temperature of 2100 K indicates warm colours like yellow, while high temperature of 5100 K indicates cold colours like blue. Most people prefer warm colours for indoor and cold colors for outdoors.

Beam angle

It is another factor that should be considered when buying LED light bulbs. To focus light on small areas, an LED bulb with narrow beam angle of 15 to 30 degrees is suitable. To lighten up wide areas with subtle lighting, then choose an LED bulb with a wide beam angle of greater than 45 degrees as it spreads the light over a larger area.
