A study of the major lighting applications by the US Department of Energy revealed that switching to light-emitting diode (LED) lighting has the potential to save us billions of dollars.
The report, Adoption of Light-Emitting Diodes in Common Lighting Applications, divided the major lighting applications into nine subgroups: A-type, directional, MR16, decorative, downlight, troffer, high-bay, streetlight, and parking garage. There were three major conclusions from the study:
- In 2012, 49 million LED lamps were installed in the nine subgroups. 41% of these installations were A-type lights and yet they have a penetration rate of less than 1%.
- Just in the 2012 calendar year, the 49 million LED installations accounted for 71 trillion British thermal units (tBtu) in energy savings and $675 million in corresponding energy costs.
- If all nine markets were to switch instantaneously to LED lamps, annual savings could reach 3,873 tBtu. This would result in savings of approximately $37 billion.
If all nine markets truly did switch overnight, we would be able to cut the annual spending on lighting energy in half.
In addition to being extremely cost effective, LED lamps possess a multitude of benefits. The DOE shared that LED lights are long-lasting, provide directional lighting with minimal light pollution, function well in cold temperatures, reduce radiated heat, are unaffected by vibration, and produce uniform illumination and safety improvements in a smaller packaging size. Overall, LED lamps are a fantastic investment and possess an infinite amount of potential as its technologies are improved. The Department of Energy is hopeful that buyers in commercial, industrial, and residential industries will accept the technology and make the decision to commit to a greener and more efficient lifestyle.
