Environmental friendly
LED lights are extremely friendly to the environment and do not contain hazardous chemicals or gases. On the other hand, traditional forms of lighting, such as incandescent and halogen lightbulbs, produce ultra-violet (UV) radiation. Similarly, compact fluorescent lightbulbs (CFL's) contain mercury, a toxic chemical that can be released if the bulb is broken or disposed of incorrectly.
Low power consumption
LEDs consume very little power, far less than standard light bulbs leading to greatly reduced energy costs and extremely enhanced global energy savings. LEDs also require far less energy to manufacture than other light sources, reducing the environmental impact of artificial lighting even further. Generally a LED is designed to operate at 2-3.6V, 0.02-0.03A current which means a LED typically requires no more than 0.1 Watt to operate.
Long Lifetime
When operating at specified voltage, current, and within specified environmental conditions, LEDs can enjoy a long life of up to 100,000 hours. A newer way to evaluate LED lifetime has been established and adopted by Environlight which is based on lumens depreciation over time to determine the Mean Time between Failure (MTBF).
High Luminous Efficiency and Low Heat Emission
Due to the special materials that are used to manufacture LEDs during electrons transition, LEDs mainly emit electromagnetic energy in the visible parts of spectrum. This is unlike incandescent filaments which are heated and emit large amounts of electromagnetic energy in the infrared spectrum which cannot be seen and is felt as heat. That is to say, LEDs can convert significantly more of the energy applied into light, and therefore LEDs have a higher luminous efficiency with substantially lower amounts of heat produced.
Environmental Protection
LEDs are made from non-toxic materials, unlike fluorescent lights that contain mercury which poses a danger to the environment and human health. LEDs are recyclable.
