Highlights: Field Assessments of the Philips 60W L Prize Entry

Extensive field testing of the Philips 60-watt L Prize entry from June through October 2010 provided a wealth of independent, unbiased data and user feedback on its performance. In all, more than 1,300 samples of the Philips entry were installed in more than 40 sites across North America, representing a broad range of facility types, fixture types, tasks or areas to be illuminated, occupancies, hours of operation, use of controls (if any), and temperature conditions.

Assessments were done in collaboration with 14 L Prize partners, primarily utilities and energy efficiency organizations, who took measurements using existing lighting, then again after installing L Prize test samples; evaluated dimming performance; and gathered qualitative user/occupant survey responses. Partner reports were then submitted to DOE.

What did users and occupants think of the lighting? Feedback from all the qualitative surveys is summarized in these charts.
