LED lights are up to 80% more efficient than traditional lighting such as fluorescent and incandescent lights. 95% of the energy in LEDs is converted into light and only 5% is wasted as heat. ... Less energy use reduces the demand from power plants and decreases greenhouse gas emissions
Mercury is not used in the manufacturing of LE lights like in the fluorescent strip. These strips contaminate the environment when disposed of in landfill waste. Switching to LED avoids the cost and time implications required for compliant disposal . It also helps to protect the environment from further toxic waste.
LEDs have a better quality of light distribution and focus light in one direction as opposed to other types of lighting which waste energy by emitting light in all directions, often illuminating areas where light isn’t required (such as the ceiling). This means that less LED lights are needed to achieve the same level of brightness given off by fluorescents and incandescent lights. Fewer lights will reduce energy consumption and will therefore be a benefit to the environment.
A longer life span means lower carbon emissions. LED Lights last up to six times longer than other types of lights, reducing the requirement for frequent replacements. This results in using fewer lights and hence fewer resources are needed for manufacturing processes, packaging materials and transportation.
