Plug & play, 220-240V power cable included, IEC output. CE certified. Not compatible with hybrid HPS-MH lamps. Fast shipping to Belgium.
Superplant Gear Box 250W Ballast — Class H Magnetic DUO Ballast for Compact Grow Spaces
The Superplant Gear Box 250W Ballast brings the same Class H insulation quality and 10-year service life of the Gear Box range to the most compact format in the series. Ideal for growers working in smaller tents, or anyone who wants a dependable, long-lasting 250W HPS or MH setup without the running costs of a 400W or 600W installation. Pair it with the Superplant Sylvania Grolux 250W lighting set for a complete, ready-to-grow package.
250W — Right-Sized for 60×60 to 80×80 cm Grow Tents
Matching wattage to grow space is one of the most important decisions in HID lighting. A 250W HPS lamp delivers effective light intensity over a footprint of 60×60 to 80×80 cm — enough for productive flowering in a compact tent without generating the excess heat that higher wattages produce in confined spaces. Running costs are also meaningfully lower: a 250W system draws roughly 40% less power than a 400W setup and 60% less than a 600W installation, which adds up over a full grow cycle. The Superplant Gear Box 250W is the natural starting point for growers new to HPS lighting, or for those who want a dedicated lower-wattage zone for clones, mothers or early-stage vegetative growth alongside a larger main room. The DUO compatibility means you can run a 250W MH lamp during veg and switch to 250W HPS at flower — no new ballast needed.

Class H Quality Regardless of Wattage — No Shortcuts in the 250W Build
Superplant applies the same construction philosophy across all Gear Box wattages. The 250W model uses Class H thermal insulation (up to 180°C winding temperature tolerance), a capacitor housed in its own metal enclosure for extended component life, and a powder-coated steel housing with all-around ventilation slots for passive heat dissipation. Four rubber feet provide stable, vibration-damping placement on any surface. CE certified, 10-year service life, 2-year manufacturer warranty. The 250W format does not cut corners on materials simply because of its smaller size — you get the same build quality as the 400W and 600W Gear Box ballasts.
Plug & Play — Power Cable Included, Universal IEC Output
The Superplant Gear Box 250W ships with a 220-240V mains power cable and features an IEC output socket compatible with all standard reflector cords on the market. Three steps to a running installation: place the lamp in the reflector, connect the reflector cord to the ballast IEC output, plug in the mains cable. Input: 220-240V / 50Hz / 1.2A. Output HPS: 100V-3A. Output MH: 135V-2.1A. Always use standard 250W HPS or MH lamps only — never hybrid HPS-MH lamps and never lamps of a different wattage. Order today for fast delivery in Belgium. Also available: the Superplant Philips Son-T Pia 250W lighting set for a proven HPS combination.

What size grow tent is the Superplant Gear Box 250W ballast best suited for?
The Superplant Gear Box 250W paired with a 250W HPS lamp is most effective in grow tents from 60×60 cm to 80×80 cm. For spaces larger than 80×80 cm, a 400W ballast will deliver better light intensity and more even canopy coverage. The 250W format is also well suited for dedicated vegetative or cloning spaces where lower light intensity is preferable to the high output of 400W or 600W HPS lighting.
Is the Superplant Gear Box 250W a good choice for a first HPS grow setup?
Yes. The Superplant Gear Box 250W is a genuine plug & play ballast that requires no electrical installation — the mains cable is included and the IEC output connects directly to your reflector cord. The 250W format is an approachable starting point for new HPS growers: it produces less heat than 400W or 600W setups, which simplifies temperature management in a small tent, and its running costs are significantly lower. The Class H build quality ensures it will last across many grow cycles without needing replacement.
Can I run a metal halide lamp with the Superplant Gear Box 250W during vegetative growth?
Yes. The Superplant Gear Box 250W is a DUO ballast compatible with both 250W HPS and 250W MH lamps. A 250W MH lamp during vegetative growth provides a blue-dominant spectrum that encourages compact, leafy development. Switch to a 250W HPS at flowering for the red-dominant output that maximises flower and fruit production. Never use hybrid HPS-MH lamps or lamps rated at a different wattage with this ballast.
How much electricity does the Superplant Gear Box 250W ballast use?
The Superplant Gear Box 250W draws 1.2A at 220-240V / 50Hz. Total system power consumption (ballast plus lamp) will be slightly above 250W due to internal ballast losses — this is normal for magnetic ballasts. On an 18-hour light schedule, a 250W HPS system consumes approximately 4.5 kWh per day. This is roughly 40% less than a 400W system (around 7.2 kWh/day) and 60% less than a 600W system (around 10.8 kWh/day), making the 250W an energy-efficient choice for compact grows.
