Subtitle B—Lighting Energy Efficiency
Sec. 324. Metal Halide Lamp Fixtures

Description: The Act amends the Energy Policy and Conservation Act to create new efficiency standards and labeling rules for metal halide lamp fixtures.

Efficiency rules: Starting January 1, 2009 (or the “date that is 270 days after the date of enactment of this subsection”), lighting fixtures manufactured for operation of metal halide lamps:

• > or equal to 150W and
• < or equal to 500W

… must contain:

Ballast efficiency: For the purpose of the Act, efficiency is measured using this formula:

Efficiency = Pout/Pin

Where:

Pout = the measured operating wattage of the lamp
Pin = the measured operating input wattage

Exemptions: The standards do not apply to:

• Fixtures with regulated lag ballasts;
• Fixtures that use electronic ballasts that operate at 480V; or
• Fixtures rated only for 150W lamps, for use in wet locations, and contain a ballast rated to operate at ambient air temperatures above 50°C.

Compliance: A review of metal halide ballasts suggests that probe-start metal halide magnetic ballasts will be virtually eliminated from new lighting fixtures after January 1, 2009. Electronic ballasts comply and so do many pulse-start magnetic ballasts. Be sure to look for ballasts that are certified to comply with the new regulation after it takes effect.

Just the fixture, not the ballast: This provision covers only newly manufactured fixtures featuring metal halide ballasts, not the ballasts themselves. (Nor does it appear to prohibit sale of existing inventories.) The replacement market is therefore not covered by this law, so owners will not be required to retrofit existing fixtures, but instead be able to continue purchasing probe-start magnetic metal halide ballasts with lower efficiencies after the enactment of this provision.

Labeling: The labeling of all metal halide fixtures manufactured on or after January 1, 2009, or “the date that is 270 days after the enactment of this subparagraph,” must contain a capital E printed in a circle on the ballast label and the fixture packaging. (The Act instructs the Federal Trade Commission to create the labeling rules by July 1, 2008.)

State action: Various states have already begun regulating metal halide fixtures which are effective until the Federal legislation becomes effective. These states include California, Arizona, New York, Oregon, Rhode Island and Washington).
