How do LED lights better protect the environment?

Have you ever wondered what kind of light bulb (LED, CFLs, or incandescent) is best for the environment?

In the three-part study sponsored by the Environment Department, there is no doubt that LEDs are significantly better for the environment than other lighting options, such as energy-saving lamps, especially incandescent bulbs.

The study considered a wide variety of factors and assessed the extent to which each bulb affected our planet's air, water, soil and resources.

This is not surprising. Smart bulbs use less energy, last longer, and use materials that are safer than any other light bulb.
Low energy consumption for smart lighting

When it comes to energy consumption, smart bulbs rule the roost.

Traditional incandescent bulbs use a lot of energy, and most of that energy is actually lost by producing heat: up to 90 percent, which means only 10 percent of the energy actually generates light.

Compact fluorescent lamps (CFLs) have significantly lower heat loss coefficients, which is one reason why they can produce the same amount of light with 75% less energy than traditional incandescent bulbs. Instead of using electricity to heat a filament, as incandescent lmps do, they pass electricity through a chamber to excite mercury molecules inside to produce light.
While compact fluorescent lamps (CFLs) are extremely efficient in using energy, LEDs for smart bulbs actually use up to 80 percent more energy than incandescent bulbs. This is partly due to the solid-state structure of LEDs, which means there are virtually no moving parts. The current is simply emitted through a semiconductor, forcing electrons to jump from one place to another, a process that results in the creation of light.
These savings not only help reduce monthly electricity bills, but also help reduce global energy production and reduce carbon emissions. For example, in 2012 alone, U.S. consumers saved more than $675 million by switching to LEDs, and a full switch to LEDs by 2032 could save the U.S. more than $250 billion in energy costs.
The service life of smart bulbs
Long life is the second most environmentally friendly feature of smart bulbs. A typical incandescent bulb lasts about 1,000 hours, or about six hours a day, and lasts about four months. CFLs provide about 10,000 hours of service life, or about four and a half years at the same rate of usage.
LEDs, on the other hand, provide an amazing 25,000 hours. This means that if you leave LEDs on for six hours a day, they will last for nearly 11 and a half years, far more than CFLs, especially incandescent bulbs.
The benefits of longevity bulbs are easy to see. One LED takes the same amount of time as about 33 incandescent bulbs, which means we don't have to produce as many bulbs. It also means less use in landfills, lower production costs, less transportation, and of course cleaner air.
Mercury-free lighting
Another important point about the environmental impact of smart bulbs is that they do not contain the same harmful substances as other bulbs, known as CFLs.
As we have pointed out before, fluorescent lamps use mercury to interact with electricity to produce light. Many people know that mercury can have some very bad effects on our health. Since mercury poisoning is most common during inhalation, damaged fluorescent tubes need to be cleaned immediately.
In fact, fluorescent bulbs have special processing steps to deal with this potentially deadly compound. Although fluorescent bulbs now contain much less mercury than they used to, they should be exposed to as little of this element as possible.
LEDs, on the other hand, do not contain mercury. While you still need to watch out for broken smart bulbs, you don't have to worry about inhaling mercury during the cleaning process.
Other features
While the energy consumption, life span and safe materials of smart bulbs are one of the main reasons for being environmentally friendly, they have other features that can help reduce your ability to perform other functions.
Compared with other bulbs, LEDs have a more concentrated light distribution. Incandescent and fluorescent bulbs emit light in all directions, and LEDs can illuminate an area without affecting the surrounding environment. Think of other bulbs as a torch, and LEDs as spotlights. This means that instead of using eight incandescent bulbs to light up a room, it is possible to use five well-placed smart bulbs to achieve the same effect.
Smart lighting also lets you set schedules so they turn off automatically. So if you're in a hurry to get to work in the morning and forget to turn it off, you won't waste the whole day with the lights on
The dimming ability of smart bulbs can also reduce energy consumption significantly. Over time, you'll notice that this simple approach can really help reduce your electricity bill
