New Ballast Energy Standards to Take Effect November 2014
In November 2011, the Department of Energy (DOE) issued new rules regulating the efficiency of fluorescent lamp ballasts, which take effect November 14, 2014. The rulemaking creates a new metric for measuring ballast efficiency and establishes a higher standard of efficiency that will impact many of today's fluorescent T8, T5 and T12 ballasts. Ballasts that do not comply will be prohibited from manufacture and import, but existing inventories can be sold until they are exhausted. The following ballast types are at greatest risk:majority of T12 electronic ballasts;
majority of outdoor-sign and residential-only ballasts; and T8 and T5 programmed-start ballasts lacking a cathode cutout design.
