LED Lights outperforming all other technologies in energy efficiency

Light fittings energy efficiency is measured in Lumen per Watt (Lm/W) and the above graph is showing the amazing pace that LED Lights have surpassed all other light sources in record time.
Today LED Lights are increasing efficiency at a pace of 20 lm/w per year and shows no sign of slowing down. As we are presently at 160 lm/w this equals to a 12% improvement per year.
