Replacement Digital Ballast for 40W (RH51-425-40L) and 55W systems (WR-1A55BL)

IMPORTANT This ballast will not work with old 55W globes

Note: This Filtermate Ballast has a slightly different connector to the Waterguard Ballast, however will replace that unit without issue

The Filtermate Ballast supports standard 4 pin Philips and Filtermate UV Globes and is interchangeable with the Cynortic 40W Ballast used in the Waterguard Silver series
