This ballast is built to last with an exclusive design that allows electrical contact to happen only when a seal is achieved. The SG ballast offers a compact design, to save space in the grow room, and a water-resistant seal to protect against misting and sprays. All SG ballasts also feature the Lock & Seal plug system, with recessed contacts to ensure safety during plug-in; a unique, circular prong pattern for secure electrical contact; and a collar that protects against accidental electrical contact. This SG ballast is wired for its 480V capability (power cord included), and is CSA certified.

Exclusive Lock & Seal Plug System

The unique pin configuration and the recessed receptacle design offer convenience, safety, and a water-resistant seal. This design allows electrical contact to happen only when a seal is achieved, guaranteeing the user's safety and preventing premature ballast failure that can occur in other brands due to inferior plug designs.
