Greener lighting-----LED lights

Lighting accounts for a large part of global electricity consumption, which is estimated by the European Commission to be about 15%. In the United States, residential and industrial/commercial lighting uses 7% of total energy (not just electricity).

With the advent of the climate crisis, we need to reduce the electricity consumption of lighting and we need to cut it drastically so that the countries that signed the Paris Agreement can achieve their greenhouse gas reduction targets.

LEDs can help achieve this: residential LED lights usually provide lighting energy efficiency (lm/W) of more than 90 lumens per watt they consume, and suppliers claim that some new models are 200 lm/W or more. In contrast, traditional light bulbs may reach 15 lm/W, halogen lamps 25 lm/W, and "energy-saving" fluorescent lamps are usually around 55-60 lm/W.

For enterprises, the light source of choice is usually fluorescent lamps, with a relative energy efficiency of about 100 lm/W. But the quality of the light it produces is dazzling, and the warmer light produced by LEDs is usually the first choice for most people. Newer LED fixtures provide the same amount of light with half the electricity of fluorescent lamps, which is a win-win situation.

Lower power consumption also creates new opportunities to make possible electric lights that were not available before—especially solar-powered electric lights without a main grid. For example, between 2010 and 2017, 130 million solar LED lights were deployed, mainly in Africa and Asia. There is clean and safe lighting after sunset, which can greatly improve people's quality of life and children can study at home.

Government regulations have accelerated the switch to LEDs in certain areas. For example, in the European Union, there is a minimum energy efficiency standard for LED lamps, and other lamps with lower energy efficiency are no longer allowed to be sold.
