ENERGY INDEPENDENCE & SECURITY ACT OF 2007 (EISA)

Effective January 1, 2009: Metal Halide 150w-500w fixture production will meet higher efficiency standards (88% for pulse start, 94% for probe start).

• This will virtually eliminate the manufacture of probe start fixtures
• One exception is significant: The 150w wet location fixtures (as rated per NEC 2002, section 410.4 (A)).
• 175w wet location rated fixtures will thus be replaced by 150w.

ENERGY ADVANTAGE

With pulse start technology you can use lower wattage fixtures for equivalent lumen output of higher wattage traditional probe start fixtures:

• 350w or 320w pulse start fixtures can replace standard 400w probe start fixtures
• 150w pulse start fixtures can replace standard 175w probe start fixtures

WHAT HAPPENS TO PROBE START?

The law allows manufacturers and distributors to sell all probe start MH fixture inventories produced before January 1, 2009.

• Ballast and lamp suppliers will continue to build components for replacement business.
• Replacement ballast and lamp business will not be impacted.

LABELING AND EISA LEGISLATION

Metal Halide lamp fixture manufactured on or after January 1, 2009, shall indicate conspicuously, a capital letter 'E' printed within a circle on the packaging of the fixture, and on the ballast contained in the fixture.

ENERGY SAVING PULSE START SYSTEMS

Hubbell Lighting fixtures powered by the most energy-saving HID technology are now marked with the "Powered by Pulse-Start™" logo*. The energy savings and lighting benefits from pulse-start systems (vs. standard probe-start ballasts and lamps) include:

• Increased lumen efficacy (lumens per watt) by as much as 24%
• Improved lumen maintenance by as much as 15%
• Extended lamp life
• Reduced warm-up time to 2 minutes
• Improved color consistency
• Reduced re-strike time to 4 to 5 minutes

*Specific wattages available for product families, refer to specification sheets for applicable model details

CARING FOR PULSE START METAL HALIDE SYSTEMS

Pulse Start MH lamps are designed without a starting electrode and thus require an external ignitor in the ballast circuit. This ignitor provides about a 4kV pulse to start the lamp by ionizing the gas between the two main electrodes within the arc tube and initiating the arc. High pressure sodium lamps which have been used for many years, employ a similar external ignitor with a lower energy pulse that is typically about 2.5 - 3kV.

Lamp cycling, failed lamps and empty lamp sockets are all conditions that cause continuous operation of an ignitor. Prolonged, continuous operation of an ignitor for weeks or months degrades ballast insulation, reduces ballast life and will eventually lead to total ballast failure. Since pulse-start MH ignitors produce more pulse energy in these abnormal conditions, pulse-start MH systems require more timely maintenance action than HPS systems. Best practice is the immediate replacement of failed lamps to prolong ballast life and to maintain luminaire performance. Hubbell Lighting recommends a routine lamp replacement process prior to lamps failing (at estimated end of life).
