Adjusta-Watt Smart Digital Ballast – Variable Output 250w/400w/600w/1000w for HPS, MH & Dual Spectrum

The Adjusta-Watt Smart Digital Ballast is a fully variable, high-efficiency digital ballast designed for growers who demand precision and flexibility from a single lighting system. Unlike standard dimmable ballasts, it runs each lamp to its exact specification — whether sodium, metal halide, or dual spectrum — at the wattage you select.

Available in 600W and 1000W models, with an Over-Drive feature that pushes output beyond rated wattage for maximum lamp performance.

Key Features

• Fully adjustable output — runs 250W, 400W, and 600W lamps (600W model) or 400W, 600W, and 1000W (1000W model)
• Over-Drive mode increases output by approximately 6% for maximum lamp performance
• Compatible with HPS (sodium), metal halide, and dual spectrum lamps
• Automatically adjusts output frequency to maintain constant performance despite input fluctuations or ageing lamps — eliminates lamp flicker
• Up to 30% more efficient than standard magnetic ballasts
• Built-in circuit breaker protection against faults
• Runs cool and quietly
