DELTA Assesses T5 High-Output Lighting System in High-Bay Warehouse Application

The LRC's DELTA (Demonstration and Evaluation of Lighting Technologies and Applications) program field-tested the performance and energy efficiency of a 6-lamp T5 fluorescent lighting system. This system, equipped with wireless motion-sensing lighting controls, was installed in a large distribution center warehouse located in Albany, N.Y.

High Bay The new lighting and motion sensor combination replaced metal halide luminaires in several storage aisles. The sensors switched the lighting to 1/3 power when no motion or activity was detected. DELTA's evaluation compared illuminances and energy usage, as well as worker feedback of the previous lighting with three light levels of the T5 fluorescent system.

The fluorescent luminaires provided three times the light output of the existing metal halide high-bay lighting, while simultaneously requiring 23 percent fewer watts. Warehouse employees favored the new lighting system as well, noting a decrease in glare when looking upward at shelved warehouse stock.

Evaluation results have been published in a 12-page brochure; this document may be downloaded free from the LRC's Web site; printed copies are also available. The New York State Energy Research and Development Authority (NYSERDA) sponsored the project.
