Spartan Series® Metal 16 Light 240 V Controllers bring you quality and reliability for an economical cost. The heavy-duty enclosure will stand up to the rigors of a growing environment while controlling your lights flawlessly. The controllers utilize a heavy-duty definite purpose contactor that is rated for ballast usage. These controllers also have built-in circuit breakers for added protection. There are two options for activation: a built-in timer for easy consolidated installation or dual trigger cords that are designed to be plugged into any 120 V timer(s). The dual trigger cords allow you to either run all 16 lights at once or to split them and run two groups of 8 lights separately. These products also feature universal outlets that allow you to use a 120 V or 240 V cord to run your ballasts at 240 V.
