While the bill is far-reaching, touching on many aspects of energy conservation, Section 324 sets energy efficiency standards for metal halide fixtures designed to be operated with lamps rated between 150 watts and 500 watts.

EISA affects outdoor and indoor lighting fixtures utilizing probe start technology in new installations but does not require replacement of existing installations. All EISA compliant products must display an encircled “E” label on all ballasts and cartons to indicate the luminaire meets all applicable Department of Energy (DOE) efficiency standards. Non EISA compliant products produced and/or imported before January 1, 2009 may still be offered for sale until inventories are eliminated, but no new probe start fixtures may be manufactured after this date.

EISA Exception

Exempt from EISA legislation are 150W ballasts in luminaires for use in wet locations where the ballast is suitable for use in ambient temperatures of 50°C or greater. It is not economically feasible to manufacture 88% efficient 150W magnetic ballasts and electronic ballasts have some difficulty operating in today’s outdoor luminaires. Other exemptions include products that use regulated lag ballasts and products that use electronic ballasts rated for 480 volts.
