Abstract

Lighting Answers: T8 Fluorescent Lamps (2006) explores developments in 4-foot, 32-watt T8 lamps, replacing the 1993 publication of the same title. This report gives lighting professionals an overview of the performance claims for initial light output, rated life, lumen maintenance, and color. It discusses the uncertainties associated with these performance attributes and with power requirements. These uncertainties can blur the distinctions in performance claims, making comparisons between lamp models more difficult. Data gathered from a limited sample of T8 lamp models illustrates the uncertainties in performance, which impacts energy costs. Knowledge of these uncertainties will help lighting professionals to evaluate performance differences and to estimate total costs more accurately.
