DOE Energy Conservation Standards for Fluorescent Lamp Ballasts
sets forth a regulation that 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
is a direct replacement for the present 'standard ballast
' and adjusts power consumption for each lighting fixture.
With 5,000 ballasts
costing around $20 each, the material replacement cost at the 12th year would be $100,000.
Investigation by the agency revealed that about 800 out of a total of 1,250 public schools in New York built before 1980 were never upgraded, and the existing magnetic ballasts
in the fluorescent luminaires most likely contain PCBs.
In the new retrofit energy saving CDM designs, these starting issues are circumvented by applying a neon argon Penning mixture to reduce the breakdown voltage of the lamp sufficiently below the minimum available voltage of ANSI rated probe start QMH ballasts
to insure reliable starting; lamps also start reliably on pulse start magnetic systems and result in the same energy saving opportunities.
are rated by the type and number of bulbs the fixture holds.
Tom Ribarich, director, Lighting Design Center at International Rectifier, said, "The IR2167 is maximized for high-end, indoor lighting ballasts
where power factor correction at the mains input is required by law.
Featuring IntelliVolt technology, the ballasts
allow end-users to significantly reduce their ballast
SKU inventory requirements, while also reducing the possibility of errors in shipping and installation.
allows a single ballast
to be deployed on lamps with different wattages with increased efficiency of the lamps in terms of power consumption and luminance.
Against this background, the paper discusses the engineering and economic characteristics of standard and energy-efficient magnetic ballasts
for fluorescent lighting.
According to Consumer Reports, magnetic ballasts
are the best energy savers, averaging 15,000 hours.
