The SG Lite 1000 Watt 277 Volt magnetic commercial ballast is great for large grow operations that need to limit their amperage. These ballasts will use less amperage as similar ballasts on 240 voltage, making them an attractive option when you want to get the most amount of lights within a given amount of amperage. If you're interested in a large quantity of these units, please contact us for bulk purchasing.

Get more ballast for your buck with the SG Lite, which is light on price but heavy on features. Experience the power of a ballast straight out of Hydrofarm's value line. This ballast is built to last with an exclusive design that allows electrical contact to happen only when a seal is achieved. The SG Lite 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 Lite 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 Lite ballast is wired for its 277V 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.
