Quick Assessment Bi-Level Stairwell Lighting Lab Test

Bi-level stairwell lighting is an underutilized technology that uses occupancy sensors to switch between higher light output (when the space is occupied) and lower light output (when the space is unoccupied) to save energy. The purpose of this testing is to validate the performance of a new bi-level lighting product that is a simple lamp replacement and does not require an electrician to install (unlike most other bi-level lighting products currently available). Lab testing will be performed to look at the products electrical characteristics when connected to various ballast. Light output will also be looked at to predict whether or not the product can meet minimum illumination levels. This is in preparation for a potential field evaluation.
