Understanding the New Fluorescent Ballast Rule EPCA 10 CFR 430

 

Status: Active
NEMA LSD 66-2012   [DOWNLOAD]

Provides educational information about the Fluorescent Ballast Rule and the associated measurement methods.

In 2008 Congress began the Rulemaking process for Fluorescent Ballasts as required by EISA 2007. The rule in effect in 2008 only covered the Federally Regulated T12 lamp ballasts for 4 foot and 8 foot T12 lamps, and Ballast Efficiency Factor (BEF) was the performance metric. As BEF was a system parameter, many factors in the lamp load and photometric measurement system contributed to a wide error range. This error range did not allow the accurate measurement of the small differences in today’s high performance electronic ballasts, so a new metric was developed, Ballast Luminous Efficiency (BLE), based solely on electrical measurements.
