A Solution for the Pasadena Library
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.
