NEMA Publishes Fluorescent Lighting Systems Standard

Aug 12, 2009 5:19 PM

NEMA, Rosslyn, Va., has published LL 9-2009, "Dimming of T8 Fluorescent Lighting Systems." This new standard is the first coordinated guidance from industry on the dimming of T8 fluorescent lighting systems and covers ranges between 100% and approximately 35% output (60mA lamp current). The publication was a result of discussions between numerous manufacturers and end-users as well as years of data gathering, testing, and analysis.

"This standard is an important step forward into the harmonization of dimming solutions for T8 fluorescent systems,” says S. Pekka Hakkarainen M.A., Ph.D., NEMA lighting division vice chair and task force on fluorescent dimming standards chair. “As programs for energy efficiency and for the effective application of lighting receive more and more attention, this standard and those that follow will provide much needed guidance to the marketplace. This standard will serve as a tool for both legislators and lighting planners to use in encouraging and designing effective T8 dimming systems."

LL 9 may be downloaded at no charge, or a hardcopy purchased for $36, by visiting the NEMA Web site.
