United States Government Increases LED Street Light Retrofit Goal

An acceleration of the “Presidential Challenge for Outdoor Lighting” program has been announced by President Obama.

The streetlight retrofit program is being managed by the United States Department of Energy as part of the Better Buildings program. President Obama had originally planned for 500,000 poles to be retrofitted with primarily LED-based, energy-efficient lighting, by 2016.

On January 23, at the US Conference of Mayors meeting, President Obama increased the goal to 1.5 million LED streetlight poles.

The installation is expected to be completed by May 2016. The Department of Energy will help the participants find and choose funding for LED streetlight conversion projects.

LED Long-Day Lighting Project Achieves Significant Results

Biosystems and Agricultural Engineering Department researchers at Michigan State University, in a collaboration with the Michigan Milk Producers Association (MMPA), announced results of a Long-Day Lighting (LDL) project. The project was funded by a Michigan Energy Office grant. The goal of the project was to document the benefits of LDL often employed by Michigan dairy farmers.

According to past research, LDL has demonstrated a positive impact on dairy cow milk production. The primary goals of the project included “properly measuring and maintaining light intensity and appropriately controlling the lighting system,” according to a Michigan State University Extension article.

The project was carried out at Wing Acres Dairy, a 100-cow dairy in Barry County, Michigan. During the project, which began full operation in January 2014, LED lights, automated sensors, and an automated control system were used. After 12 months of research at the dairy, the results were significant, including an 8% increase in milk production.

Data from the dairy’s operation in 2012 and 2013 was analyzed to determine if the increase was a result of LDL or other factors. It was ultimately concluded that the increased milk production during the project was directly attributed to the LDL system.

Before the project began, metal halide lights located in the barn were replaced with LED lights. This resulted in a reduction of at least 50% in lighting costs. Other important aspects of the project included using an accurate and reliable automated control system for LDL management.

Also important to note: the dairy farmer noticed that the cows within the milking herd were less agitated and more docile with the LED lights and LDL system.
