Advance Transformer HM-2SP20-TP Ballast

Philips Advance HM-2SP20-TP is a magnetic fluorescent ballast designed to drive two lamps in compatible fixtures, providing the essential start-up and current regulation that keep two-tube luminaires operating consistently and safely. It is cataloged by Philips Advance as a HM-2SP20-TP ballast, with Magnetic Fluorescent construction and a place in the Standard ballast family; verified cross-reference SKUs include 8G3867 and 8G3867WF, which correspond to this model in catalogs and replacement guides. As a two-lamp ballast, HM-2SP20-TP supports two fluorescent tubes within a single ballast unit, aligning with common two-lamp configurations in older commercial luminaires. The exact electrical ratings, lamp compatibility, mounting provisions, and installation guidelines are defined by the fixture and the 8G3867/8G3867WF variants, so replacement should be performed with the same model family and in accordance with local electrical codes. Consulting the fixture's documentation or Philips/Advance catalogs will confirm the appropriate lamp types and mounting arrangements for safe and reliable operation.
