New Publication: NLPIP Diagnoses Lighting Problems
By Jennifer Taylor
Lighting Diagnostics

Lighting systems are becoming more complicated and harder to specify, install, and commission properly. To help facility managers, lighting specifiers, and building owners, the National Lighting Product Information Program (NLPIP) is now publishing Lighting Diagnostics reports. Lighting Diagnostics documents actual cases in which NLPIP researchers have helped to diagnose and solve lighting problems in commercial buildings.

In the first issue, Dimming T8 Fluorescent System Problems, NLPIP worked with a major retail chain that had encountered problems with its dimming fluorescent lighting systems, including early lamp failure. This issue summarizes the problems encountered and the evaluation and findings of the NLPIP Lighting Diagnostics team sent to investigate. The investigators determined several problems relating to the lamps, ballasts, luminaires, lamp holders, and the installations themselves.

“We hear a lot of anecdotal reports about problems in the field with many types of lighting systems and applications, particularly daylighting and dimming systems,” said Conan O’Rourke, NLPIP program director. “With the Lighting Diagnostics program, we hope to learn more about why systems don’t perform well in the field when they do in the lab.”

NLPIP’s Lighting Diagnostics service provides site-specific consultation, diagnostics, technical assistance, testing, and evaluation to help diagnose and solve lighting problems in commercial buildings.

NLPIP is currently seeking commericial sites with lighting application problems for evaluation, particularly issues with dimming and shortened lamp life. Interested building owners, facilities managers, or occupants may contact NLPIP at lrc@rpi.edu for more information about the program.
