Presentation by John Paulson, City of Hutchinson. An LED street lighting forum was hosted at the League of Minnesota Cities Annual Conference on June 19th, where a packed room of 40 people learned first-hand from a tremendously knowledgeable line-up of speakers from across Minnesota.

LED Street Lights: Better Light, More Savings
Thursday June 19, 2014John Paulson Environmental Specialist
Questions?????...?
? What…? Kind of fixtures do we have
? MH, MV, PSMH, HPS, LPS, Induction, LED
? Is the maintenance frequency
? Is CU, CRI, CCT, Efficacy, Lumen, etc.
? Are Photometric Reports, Luminaires, etc.
? Who…? Owns the lights/poles
? Pays for the electricity
? Can provide technical guidance
? Has money to make it possible
? Is the right product supplier
? Where…? Are the tools to help me make decisions
? Are the street lights located
? Do we start/stop
? Can I get more information
? When…? Does it make sense to move forward
? Does it not
? Can we start
? Do fixture warranties expire
? Should we replace new rather than retrofit
? Why…? Should we replace street lights
? NOT?
? Are LEDs better
? Should we care
? And the all important HOW…? Can we hit a fast moving target
? Do stakeholders feel about it
? Can the utility help
? Do we pay for it
? DO WE KNOW WE ARE MAKING THE RIGHT DECISION?!?!?!
Special Thanks To:
Checklist of Completed Steps when Considering a Switch to LED Roadway Lighting Become acquainted with terminology, technology, and major manufacturers. Use a CCT and CRI suitable for the roadway lighting application. Check Ingress Protection (IP) ratings and choose appropriately for application. Establish whether a RoHS compliant device is preferred. Determine roadway lighting distribution classification and recommended illuminance levles. Complete as much of the “LED Roadway Lighting Specification” form as possible. Send form to manufacturers. Request and examine operating temperature data and how it is used in luminaire efficacy
and lumen depreciation calculations. Request and examine AGi32 simulations and photometric reports. Ask about detailed luminaire warranty (three to five years on parts is deemed reasonable
for roadway lighting). Inquire about control systems and compatibility. Contact electricity provider and inquire about rebates for energy-efficient roadway lighting
projects. Conduct an economic payback and life-cycle cost analysis. Obtain at least two working samples of each luminaire under consideration and install on
adjacent poles to verify performance. Assess glare and compare to currently installed technology.
