LED lights are today everybody's choice.

Before the invention of electricity, when fossil fuel was the only source for light and warmth, atmosphere was continuously being polluted by the burning of fossil fuels. However, the world was so sparsely populated in those days that the lighting technologies posed no threat to the environment. The arrival of electricity changed things a lot, but today even incandescent bulbs, which were the best thing that could have happened to the world when it was first invented, are way below fluorescent lights and LED lights in the evolutionary scale.

Fluorescent lights which work by heating trapped gas use only less than half the amount of energy as incandescent lights which use the technology of passing current through a filament. A fluorescent bulb on an average lasts about 10 times as long as an incandescent bulb as well. But fluorescent lights are an environmental threat because the amount of mercury contained in one fluorescent bulb is enough to pollute about 2000 gallons of liquid. And though it lasts longer than incandescent lights, they last only an average of 1000 hours and cannot compare with LED lights that could last anything from 50,000 to 100,000 hours.

The number of discarded fluorescent lights is steadily increasing in garbage dumps and the mercury seeping down from it will be large enough to pollute groundwater after a stage. As such, though fluorescent lights are considered better than incandescent lights for energy efficiency and thus for reducing carbon footprints, it poses its own set of hazards.

LED lights are the answer to all these problems. Besides lasting long, it consumes only about one-tenth the energy consumed by incandescent lights. LED lights also do not contain any hazardous substances like mercury, and are fully environment friendly. Further, the light intensity of LED bulb clusters is such that it is possible to make smaller, low profile vehicle lights using LED lights. When smaller lights are mounted on the roof of the vehicles, lesser energy is required to propel the car forward as there is less difficulty in overcoming air drag. This too helps in energy saving and reduces carbon emissions.

Governments of various countries and states are making a concerted effort to transition into LED lights to reduce carbon footprint by improved energy efficiency. Australia has made a long term plan to raise its energy standards by limiting the use of incandescent bulbs from 2009 onwards. The attempt is not to completely transition to LED lights at this stage but to switch to both fluorescent lights and LED lights. It is believed that by the shift the country will be able to reduce about 800,000 tons of emissions within three years starting from 2009.

Venezuela and Cuba are also among countries that are planning a gradual transition from incandescent lights into LED lights. The state of New Jersey is planning a phased removal of incandescent lights from government building. A similar plan is on the anvil in the state of California also where it is planned to stop the usage of incandescent lights altogether.
