4. Advantages of LED Street Lights
Energy savings of percent compared to the predominant HPS lighting technology (on average);
Reduced energy costs;
Reduced maintenance costs of 50 percent or more due to their longer lifespan;
Improved lighting quality from better color rendering than the predominant HPS lights; and,
Opportunities to install advanced/connected controls

6. Eversource is Addressing Health Concerns of LED Street Lighting
Health concerns from disruptions to circadian rhythm from blue light sources
Includes tablets, cell phones, computers, LED street lights
American Medical Association recommends
Retrofitting street lighting to save energy
Using “warmer” color lighting (color temperatures ≤ 3000 K)
Eversource is using 3000K LEDs street lights in retrofits

DEEP approved with conditions the Electric and Natural Gas Conservation and Load Management Plan
Condition 3 was outlined in DEEP’s Order 3:
“The Companies shall submit to BETP for DEEP's records a report that summarizes the state of street lighting in Connecticut. Specifically, the Companies shall provide best estimates of the numbers of street lighting fixtures owned by the utilities, municipalities, and the State of Connecticut. To the extent such information is available to the Companies; the report shall quantify how many streetlights in each category have been upgraded to LED technology and/or with streetlights in each category have been upgraded to LED technology and/or with advanced lighting controls. The Companies will provide recommendations on the timeline for upgrading street lights in each of these categories, and the recommended funding mechanism for such upgrades.”
August 9, 2016 – Eversource submitted our response to Order #3
August 23, 2016 – DEEP issues Approval of Conditions #3 of C&LM Plan

12. AMA Statement
On June 14, 2016, The American Medical Association (AMA) issued an official policy statement on LED street lighting that included three recommendations :
First, the AMA supports a "proper conversion to community-based Light Emitting Diode (LED) lighting, which reduces energy consumption and decreases the use of fossil fuels."
Second, the AMA "encourage minimizing and controlling blue-rich environmental lighting by using the lowest emission of blue light possible to reduce glare."
Third, the AMA "encourage the use of 3000K or lower lighting for outdoor installations such as roadways. All LED lighting should be properly shielded to minimize glare and detrimental human and environmental effects, and consideration should be given to utilize the ability of LED lighting to be dimmed for off-peak time periods.”
