HIGH FREQUENCY ELECTRONIC BALLASTS<br />
Reading Date Codes for Warranty Date on <strong>Electronic</strong> <strong>Ballasts</strong><br />
Most date codes are stamped on the back of the ballast (opposite the label side). The date code is part of a larger group of numbers and<br />
letters, which call out the various codes for the factory where the ballast was manufactured. Depending upon which <strong>Advance</strong> Transformer<br />
factory manufactured the ballast, the date stamp can vary slightly, in terms of its position on the ballast and the number sequence.<br />
Some electronic ballasts manufactured from 1988 to 1991 may have the date code in ink stamped on the ballast label. Some ballasts have<br />
the manufacturing code printed in ink on the end of the ballast.<br />
A typical date code for an electronic ballast will have the week and the year the ballast was manufactured. Some ballasts will have the day<br />
of the week included too.<br />
ADVANCE TRANSFORMER’S ELECTRONIC BALLASTS HAVE A (5) YEAR WARRANTY FROM DATE OF MANUFACTURE, EFFECTIVE WITH<br />
MANUFACTURING IN JANUARY, 1994 (DATE STAMPED 01-94). ELECTRONIC BALLASTS WITH A DATE CODE PRIOR TO THAT DATE, HAVE<br />
A THREE YEAR WARRANTY (DATE STAMPED 52-93 OR EARLIER).<br />
