NEMA Publishes LL 9-2009 Dimming Of T8 Fluorescent Lighting Systems
July 28, 2009

The National Electrical Manufacturers Association (NEMA) 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; LL 9 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,” said S. Pekka Hakkarainen MA, PhD, 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 www.nema.org/stds/ll9.cfm, or by contacting IHS at 800-854-7179 (within the U.S.), 303-397-7956 (international), 303-397-2740 (fax), or global.ihs.com.

NEMA is the association of electrical and medical imaging equipment manufacturers. Founded in 1926 and headquartered near Washington, D.C., its approximately 450 member companies manufacture products used in the generation, transmission and distribution, control, and end use of electricity. These products are used in utility, industrial, commercial, institutional, and residential applications. The association’s Medical Imaging & Technology Alliance (MITA) Division represents manufacturers of cutting-edge medical diagnostic imaging equipment including MRI, CT, x-ray, and ultrasound products. Worldwide sales of NEMA-scope products exceed $120 billion. In addition to its headquarters in Rosslyn, Virginia, NEMA also has offices in Beijing and Mexico City.
