  Title A Win-Win-Win for Municipal Street Lighting: Converting Two-Thirds of Vermont's Street Lights to LED by 2014. Type (up) Journal Article
  Year 2012 Publication American Council for an Energy-Efficient Economy. Abbreviated Journal  
  Volume Issue Pages  
  Keywords Lighting Systems  
  Abstract Reducing energy costs and enhancing the nighttime environment with LED street lighting

is by now well understood. However, few municipalities and utilities have successfully taken

advantage of this opportunity to convert their street lighting operations to LEDs. Before a

system-wide conversion of existing street lights can occur, a utility must obtain the large amount

of required capital, identify appropriate LED street light equipment for their applications,

consider changes in utility rate structures, and design effective methods for recovering costs.

Using Vermont as a case study, this paper presents a partnership model among the statewide

energy efficiency utility, the state’s largest electric utilities, and several municipalities. The

model was designed to overcome the challenges to widespread LED street light conversion. By

2014, more than two-thirds of Vermont’s municipal street lights will be upgraded to LED

technology. The conversion will: (1) provide municipalities with better nighttime street lighting

and significant cost savings—at no additional capital expense to the municipalities, (2) deliver

8,000 MWh of cost-effective new savings to the energy efficiency utility, and (3) deliver

financially attractive returns for Vermont’s utilities. This win-win-win model is scalable and

replicable, and is now being considered in Massachusetts and Rhode Island

  Title Optimization of solid-state lamps for photobiologically friendly mesopic lighting Type (up) Journal Article
  Year 2012 Publication Applied Optics Abbreviated Journal Appl Opt  
  Volume 51 Issue 35 Pages 8423-8432  
  Keywords Lighting Systems; Circadian Rhythm; Color; Equipment Design; Humans; Light; *Lighting; Melatonin/metabolism; Photobiology/*methods; Semiconductors; Time Factors; Vision, Ocular  
  Abstract The circadian and visual-performance-based mesopic systems of photometry were applied for the optimization of the spectral power distributions (SPDs) of the solid-state sources of light for low-illuminance lighting applications. At mesopic adaptation luminances typical of outdoor lighting (0.1-2 cd/m(2)), the optimal SPDs were obtained through the minimization of the mesopic circadian action factor, which is the ratio of the circadian efficacy of radiation to mesopic luminous efficacy of radiation. For correlated color temperatures below ~3000 K, the optimized dichromatic light-emitting diodes (LEDs) are shown to pose a lower circadian hazard than high-pressure sodium lamps and common warm white LEDs; also they are potentially more efficacious and have acceptable color rendition properties under mesopic conditions.
