A Solution for the Pasadena Library

By LEDtronics, Inc.

LEDtronics has provided many clients with custom solutions to fit very specific needs. The City of Pasadena came to LEDtronics to provide a custom solution for the Pasadena Central Library.

The Library had over 30 historical pendant lighting fixtures hanging from the vaulted ceiling of its main common areas. These fixtures used two ballasted metal halide bulbs that were inefficient in many ways:

  • Using 900 watts of energy per pendant fixture, that resulted in creating inefficient lighting in the library’s main common areas
  • Shorter life cycle of both bulbs and ballasts resulted in costly maintenance

The Library’s goal was to reduce the burdensome maintenance of the 25-foot-high fixtures, reduce energy consumption costs and improve the quality of light for their patrons.

LEDtronics was able to meet these goals by customizing a high powered LED cluster to fit the existing pendant fixtures and maintain their historical integrity. These 95 watt clusters replaced the two 450 watt bulbs and reduced the energy consumption by nearly 90%. The clusters were properly fitted to point directly up at the reflector surfaces to achieve maximum luminance in the Library’s common areas. Due to the low maintenance nature of LED technology, the Library now saves thousands of dollars a year on periodic maintenance the City would otherwise need to schedule.

After this success, LEDtronics worked with the Library to also replace metal halide bulbs and ballasts in the adjacent Centennial Room with a similar LED cluster adjusted and dimmed for a lower hanging pendant fixtures.

The City now has an annual savings over 50,000 KwH of energy due to a solution provided by LEDtronics to the Pasadena Library. We continue to partner with the City of Pasadena to create additional lasting LEDtronics LED solutions to fit their many needs.
