Dear all, The Led lights are eco friendly, electricity saving and cheap source of light than CFL. But according to research survey it is found that, It may be dangerous to living being due to presence of lead, arsenic, copper and nickel on it. Can it triggers cancer and what will be the effect of its waste (two or four wheeler vehicle light breakage during accident) on human being and accumulation of its heavy metals on aquatic life?
Hello Mahadev,
Every research has two sides: cost and benefit. We always focous on benefit and after its use we talk about its cost. So, before release, everything must be tested for its cost and benefit. So far, the source of light in future is concerned then anyone doing research in this field shoud think about the use of the natural light by the process of deviation.
From efficiency point of view Light Emitting Diode (LED) is good than Compact Fluorescent light (CFL) and other lights.
In comparison of CFL, LED consume almost 50% less electricity, while CFL consume 75% less electricity than tube light.
Life if LED is 50000 hrs and that of CFL is 8000 hours.
CFL is comparatively less costly. The difference is almost 50%.
LED is durable and CFL is fragile.
In comparison of CFL, LED is smaller in size.
LED produce less heat while CFL produce more heat. This increase sensitive of CFL toward rain drops.
LED is recyclable and CFL is repairable. But recycling of LED is not in practice but repair of CFL is in practice.
Personal preference may be different. If someone ask me, I will prefer CFL over LED. Because I like it's shape and look. Besides this, my eyes are more sensitive to LED. Other may like LED.
The use of tube light is toward decrease. It is costly, but more electricity (almost 70%) is required.
It is also good looking and can work for a long time. Most of the people prefer tube light over LED and CFL.
I think in future researchers may work on LED and may make it more cost effective and good looking. But we don't know, there may be another technology in near future.
