Switch to LED Lights
by Serena Woods
LEDs (Light Emitting Diodes) are the newest and most promising invention in the lighting industry. LEDs have many advantages over more traditional forms of lighting systems.
Conserve energy
LEDs generally consume low amounts of power to produce light. In contrast to other types of bulbs, LEDs are more efficient and therefore require less power to produce the same amount of light. The Center for Efficient Energy Consumption conducted a study which states that "LEDs reduce power consumption by more than 60% when compared to other forms of lighting."
LEDs also have a long service life. Frequently switching them on and off does not affect their performance. People do not need to replace LEDs for many years, unlike traditional light bulbs and tubes.
LEDs are more energy efficient. They have an estimated energy efficiency of 80 to 90%. This means that they use 80-90% of electrical energy, and only around 10-20% is lost and converted to heat energy. In comparison, traditional bulbs have an estimated energy efficiency of only 20%.
Safe energy
LEDs do not contain any harmful materials. They are 100% recyclable, which makes them easier to dispose of responsibly. Many traditional forms of lighting contain materials that can be dangerous. LEDs are a safer option.
Minimal disadvantages
Researchers have found that LEDs can have a negative effect on our health. They suggest that LEDs may cause headaches and affect our sleep. However, the many benefits of LEDs outweigh these concerns.
Make a difference
If more people switch to using LEDs, it will save considerable energy. So, do your bit and start using LEDs.
