According to ENERGY STAR, energy efficiency lighting is the fastest, cheapest, and largest untapped solution for saving energy, saving money, and preventing greenhouse gas emissions.

There have been significant changes in lighting in regards to energy consumption and industrial demand for light. The lighting market is in a period of great change with new technology affecting the market in the coming years. 

LEDs as disruptive technology

LED has been introduced and promises large energy savings potential.  LED technology directly challenges traditional light sources such as incandescent, halogen, high intensity discharge (HID), and fluorescent light sources.  Today, LEDs are competing successfully across a variety of applications due to their high quality and cost-effective performance. 

LED Cost Barriers

The impact of LED technology has been limited due to lamp cost.  LEDs are now penetrating into general illumination applications at an accelerating rate.  The technology will need continued research and development to reach high penetration in all aspects of industrial lighting. 

Public awareness campaigns assisted by electric utilities across the U.S. have been effective in shifting the market towards more energy efficient technologies. 


The Design Lights Consortium is a collaboration of utility companies and regional energy efficiency organizations that offers technical information and training.
