Municipal Street Lights• Lighting Up the World• Benefits of LED• Sioux Falls Pilot Projects and Results• Citizen Survey• 57th Street Tunnel

World Wide• First known street lights, Peking 500 B.C.• Rome had vegetable oil lamps• First public street lights, 1417 London• First US system was Baltimore, 1816• 304 million street lights estimated as of

May 31, 2016• 84% of street lights will be LED by 2025

Benefits of LED• Longer life span – HPS 3/5 yrs., LED

14/16 yrs.• 10 year warranty • Reduction of maintenance and $• Don’t carry toxic materials like mercury• Work better in cold weather• Instant on – no warm up period• Brighter colors• IES Dark Sky compliant

Benefits of LED

Benefits of LED• LED – 95% of the power for a lamp is

converted into visible light with no heat/IR (Infrared)

• HPS – 10% of the power for a lamp is converted into visible light and the rest is turned into heat/IR

Benefits of LEDNational average:• $.115/KWH operating 2 hours/day• 12w LED – $1.00/year• 14w CFL – $1.17/year• 60w incandescent – $5.00/year• 250w HPS – $120.45/year• 1000w interstate tower light – $530.00/year

Sioux Falls Street Lighting• Municipal manages 20,000 street lights• Sioux Falls has 4 power providers• Two systems – residential and commercial• Flat rate for residential street lights• Advantage to owning our own street lights

SF owned $102, PP owned $347• Change of business plan 2018

Sioux Falls LED Pilots• 65 street lights – all sizes, various

neighborhoods• One-year test pilot• Savings of 54% in power!• Lake Lorraine – October 2014• Past – 250w HPS, $.33/day • Now – 107w LED, $.15/day• Residential – 39w LED, $.03/day
