When considering an LED retrofit or incentive policy, do your research (MAGAZINE)

Feb. 3, 2010
Evaluation of 250 LED bulbs and fixtures from 23 leading vendors indicates that LEDs offer compelling payback periods when compared to conventional incandescent and halogen lighting solutions. However, as DAVID RAEZER and ROMAHLO WILSON describe, LEDs are not yet competitive as replacements for compact fluorescent, metal halide, and linear fluorescent lights.

While LEDs can save substantial energy and maintenance costs over the course of their lifetime, the investment case associated with their adoption is often difficult to discern among the maze of general lighting reports, marketing materials, and strong competition from conventional lighting solutions. The information and independence that municipalities, institutions, and real estate stakeholders need is often so illusive that a large municipality asked Cleantech Approach (CTA) to determine the scenarios—spanning a range of vendors, products, applications, and endmarkets— under which it made financial sense to move ahead with LED implementation.

As lighting accounts for approximately 16% of the municipality’s energy consumption, it is a central part of its energy efficiency and sustainability efforts. This information was critical as the municipality considered retrofitting their own facilities and sizable infrastructure, as well as creating effective legislation and financial incentives for property owners and citizens to retrofit their own properties.
