Projects Updates for LED Bi-Level Lighting pilot

Search tips:
  • This form will search for words in the title OR the description. If you would like to search for the same term(s) across both the title and description, enter the same search term(s) in both fields.
  • This form will search for any of the words you enter in a field, not the exact phrase you enter. If you would like to search for an exact phrase, put double quotes (") around the phrase. For example, if you search for Bike Path you will get results containing either the word Bike OR the word Path, but if you search for "Bike Path" you will get results containing the exact phrase Bike Path.
  1. LED detail information from Eva Sweeney

    Associated Project(s): 

    Attached are the specifics from our parking lot E-15.  We were reusing 27’ poles on approx. 90’ staggered spacing. The BetaLED occupancy sensors are operating right at their max distance, but seem to give good coverage for both cars and pedestrians.  We were targeting a low footcandle level, only about 1.0fc average.

    Another LED fixture we have used with success is the Lithonia DSX2.  Due to taller poles (37’) on that project we did not use the occupancy sensors.  Lithonia has since indicated that their sensor may be able to adequately cover motion at that height, but we have not tried it.

    University of Illinois is now considering bi-level LED lighting for almost all of our new outdoor installations, particularly parking lots that don’t get a lot of traffic late at night.  Between the energy savings and reduced maintenance, it’s working out very well so far.
