Your reduced energy use impacts on power generation, as power that isn’t used doesn’t need to be generated. That creates less environmental impact and reduces problems with power generation capacity.
An average installation of LED lights, in an office for example, can save up to 30-50 metric tons of CO2 each year. We’ll calculate the exact reduction in your own carbon footprint.
LED lights contain no harmful chemicals or toxic by-products, which are problems that make fluorescent tubes inconvenient and difficult to dispose of.
