Is Prakash LED light truly eco-friendly?

Absolutely!

Let me mark it by points.

1. No loss of energy in the form of heat.
2. All directional lights always waste some energy. LED lighting is mono-directional.
3. Less requirement of electricity – leads to less production in national level.
4. Savings on natural resources – whatever be the generation process, surely we are converting some form of energy to electricity.
5. Indirect savings: Perfect example is reduction in cooling cost – air conditioners for example.
6. Longer life leads to reduction of environmental impact. Impact during manufacturing, packaging and shipping.
7. Contains no mercury. Mercury from scrap of CFLs seeps into water supply and adversely affect sea life, and people who eat it.

So, be environment conscious and use Prakash LED.

"LIFE" of an LED bulb

Sometimes there is a certain understanding that changes over time. It happens in many parts of our life, workspace, love etc. etc. Same is the story about the “Life” of an electric bulb. With the typical yellow round lamps (GLS) we knew it’s life is over when the small thread is “cut”. But that is not considered as the life of a bulb.

Any bulb, when lit for the first time provides the maximum lumen. And it reduces and reduces and reduces – so slowly, that we do not understand the change. Experiments show that in a typical office people will not notice the change in amount of light till it hits 30%. Means the old lamp is providing 70% of its initial capacity. And that is majorly considered as the “LIFE” of a bulb – how long it can provide 70% of its initial brightness.

Let us start with GLS. A normal incandescent lamp has a life of 750 to 1,000 hours. A better make can go up to 2,000 hours (maximum).  For Halogen incandescent lamps the maximum figure is doubled – 4,000 hours.

If we consider CFL, they give a pretty good data. CFLs generally lose not more than 20% of initial brightness over 10,000 hours life. High-quality linear fluorescent lamps (T8 and T5) using rare earth phosphors will lose only about 5% of initial lumens at 20,000 hours of operation.

In this context Prakash LED is a monster here. Prakash Group, as a manufacturer of high-power white LEDs estimate a lifetime of around 50,000 hours to the 70% lumen maintenance level. And, depending on drive current, operating temperature, etc. some of Prakash LEDs have a useful life values greater than 100,000 hours.

So, switch over to Prakash LEDs – it is a lifetime investment.

Energy efficiency and Prakash LED

What is energy efficiency? In smart words – getting the same service with less input of energy. In the field of lighting this statement can be mapped as getting same light using less electricity. This is the latest saga of a long-long journey through ages. When the first light bulbs were invented in 1879 by Edison, the cost of producing electricity was high. But soon, it came down and using electric light became cheaper than traditional oil lamps. That was the mere beginning. Afterwards we got the normal tube lights of 4 feet length, the CFL’s and then the LED’s for domestic usage.

Total amount of emitted light from a source is measured by the unit lumen (lm).  And our usage of electricity is measured by the unit watt (w). So, the ratio of lm/w determines the highness or lowness of energy efficiency of a light source.

Say for example, if a 60watt lamp gives 800 lumens and another 10watt lamp gives 400 lumens — then which one has got more energy efficiency?

The TOTAL lumen is not the only factor here; you have to think as ratio, as I wrote. The first 60w lamp is giving 800lm – higher than 400lm, surely. But to produce double quantity of light it is using 6 times energy than the second one.

Now think from the reverse angle. Think, you need 8,000 lumens for your entire apartment. Then if you use the first kind of lamp, you’ll need 10 such (800lm x 10) and you’ll end up burning 600 watts (60w x 10). But if you use the second kind — you need to burn 200 watts (10w x 20), using 20 (400lm x 20) such lamps.

So, your electric bill will be 1/3^rd per month by using the second lamp !!!

Prakash LED does this exact thing. If you use a 60w normal lamp (GLS) – you get around 800lm. Similar light you’ll get using a CFL of 12w.

And Prakash LED? Well, you need to fit a lamp of 7w only.

What is so special about LED?

Well, there is no straightforward answer as LED started or modified more than a single thing in the history of lighting. The basic six advantages of using LED lamps can be considered as energy efficiency, long life, eco friendliness, low-voltage functioning, low-temperature functioning and better user experience (Ux).

Next, we’ll discuss these five points in details.
