Will my dual voltage 120/240V ballast operate on 208V or 277V?

Our Xtrasun and SG magnetic ballasts currently only have 120V & 240V capability. Our Powerhouse ballasts are wired for 120V and 240V, but have the capability to be rewired to 208V or 277V. If you already have a Hydrofarm ballast, consult a certified electrician to rewire this for you. For warranty coverage, ballasts with these voltages will need to be special ordered.

Are my ballasts generator-ready?

All of the ballasts we sell are generator-ready. Generator-ready ballasts include: Xtrasun ballasts, Phantom ballasts, Phantom II ballasts, and Quantum ballasts.

I have a 1000W ballast. Can I use a 400W or 600W lamp (bulb) in it?

As a general rule, lamps (bulbs) can only be used with ballasts that specify the same wattage rating. A 1000W lamp can only be used with a 1000W ballast, a 400W with a 400W, etc. Many ballasts are made to handle only one wattage level. An exception to this would be the Xtrasun "Dial-a-Watt" ballasts (XTEDW-), which have various settings for output power and are meant to be used with a lamp of the same wattage as the dial setting (for example, use a 600W bulb when the ballast is set to 600W, etc.).

Can an HPS ballast be used to power a metal halide lamp?

This is never recommended. The ballast and lamp (bulb) type (wattage and HID lamp type) must match. Convertible ballasts, however, can be switched between MH and HPS modes. There is also the option of using a conversion lamp. These are lamps that are designed to produce a MH spectrum while run on an HPS ballast, or vice versa. Phantom digital ballasts can ignite HPS or MH bulbs, except for the 750W model, which is meant only for HPS.
