9. Pack Codes Example for a B232IUNVHP-N010C
A complete part number (or SKU) is the Catalog code plus the Pack code
The catalog code (on previous slide) identifies a unique ballast.
The same catalog/ballast can be packaged in multiple ways. This “pack code” is represented in the last four digits following the catalog. In the above example the pack code is 010C.
Typical pack codes include:
010C – carton pack of 10 ballasts
000I – shrink wrapped unit of one, known as “individual pack” or I-pack
000T – tray pack or pallet quantity
000K – Distributor kit for CFL ballasts.
There are many variations of pack codes available and are specific to the catalog. Consult factory for available options.

10. Thank you “Spec Finder” Tool
The website: has a ‘Spec Finder’ tool which allows you to easily type in the catalog number and view the individual spec sheet with full product information. For example ...
Go to There are two ways to get to the “Spec Finder” tool.
Type the catalog number into the catalog field which auto populates with options. If you don’t know the catalog number use the other fields to identify the ballast.
