Less Energy Consumption in LED Lights, Mean More for the Ecosystem

July, 2018

As a civilized human, taking care of the environment is an accountability that nobody can deny.

Most of us are aware of environment-friendly processes such as recycling to reduce the quantity of waste we generate and reduce the carbon trail. However, many people are still unaware of the latest and forthcoming technologies that can be applied to help reduce carbon emissions. A good example in this case is LED lighting, which offer a plethora of environmental advantages.

On the other hand, traditional incandescent bulbs work by passing an electric current through filament which becomes very hot and results in emitting light. Much of the electricity is wasted as heat (approximately 90%), making these inefficient, wasting electricity and producing carbon dioxide to a huge extent.

More CO2 + more energy consumption ≠ eco friendly environment

Effects of CO2 on Environment

Let me first discuss some effects of CO2 on the environment and how we can get rid of it by using LED lights:

The increased levels of CO² in the earth’s atmosphere have produced a greenhouse effect which is gradually warming up the earth. Approximately, at the end of the 21st century, the earth’s mean temperature could boost Carbon Dioxide 1.1 to 5.8 degrees centigrade if no modification is done. If this were to happen, it could be devastating for mankind and all other species. The effects expected are:

  • Extreme weather patterns, storms, droughts and flooding

  • Rising sea levels, resulting in coastal flooding

  • Extinction of many species due to their inability to adapt to the changes in the ecosystem


Thanks to LED Lights

The one thing that we can do to save our environment is by switching from traditional CFLs to LED lights. Compared to fluorescent and halogen lighting solutions, LED lights use a reduced amount of power per watt output. These lights offer improved lumen outputs with every use, indicating that a reduced amount of power is consumed which decreases the release of CO2 gasses. When you believe that they consume less power continuously throughout the year, their process is undoubtedly eco-friendly. Many countries are working on the latest LED technology; also LED lights in Pakistan are getting fame to a great extent.

The other advantages of LED lights that interlink less energy consumption and assure an eco-friendly environment are as follows:

  1. Energy Efficient

LED lights are up to 80% more efficient than conventional lighting such as fluorescent and incandescent lights. 95% energy in LEDs is transformed into illumination and only 5% is exhausted as heat. On the other hand, fluorescent lights convert 95% of energy to heat and only 5% into light. LED lights also consume much less energy than traditional lighting; a usual 84-watt fluorescent bulb can be replaced by a 36-watt LED to give the same level of light. Less energy use decreases the demand from power plants and reduces greenhouse gas emissions.

  1. Less Lights Needed

LEDs have a high quality of light distribution that focuses the light in one direction dissimilar to other kinds of lighting which waste energy by emitting light in all directions, often illuminating areas where light isn’t necessary (such as the ceiling). This means that fewer LED lights are needed to attain the same level of brightness given off by incandescent and fluorescents lights. Small number of lights will trim down energy consumption and will ultimately be a benefit to the environment.

  1. Ecology

LEDs do not hold toxic materials such as mercury and other metals that are dangerous for the environment. These are 100% recyclable, which helps to trim down carbon dioxide emissions. They are enclosed with chemical compounds that are responsible for the colour of its light (phosphor), which are not dangerous for the environment. Thus, results in contributing more to the ecosystem as compared to traditional lighting.


  1. No IR or UV Emissions

Less than 10% of the energy consumed by incandescent bulbs is converted to light; the majority of the power is transformed into infrared (IR) or radiated heat. Too much heat and ultraviolet radiation (UV) presents a burning danger to people and other living things. LEDs produce virtually no UV or IR. Fast advancements in LED lighting technologies, with more advancement, have resulted in lowered expenses and increased consistency of LEDs. And while it may be tempting to believe LEDs are the correct choice for all applications because of their energy efficiency, choice should be based on a combination of reasons as well as light quality and distribution, dim ability, and expected lifetime.


  1. Intelligence 

Today, light can do so much more than lighten our path. It can lighten our impact on the surroundings, make our environment more protected or boost up the comfort and efficiency of any interior space. Coupling LED lighting with intelligent sensors and controls, can facilitate to construct smarter, more sustainable solutions. It can ultimately lessen the energy consumption and protect the environment.
