| Q: | Will my dual voltage 120/240v ballast operate on 208v? |
| A: | Some of our magnetic ballasts have a 208v lead coming out of the transformer located inside the ballast housing. The Xtrasun magnetic ballasts currently do not have extra voltages, only 120/240V. You may have the Powerhouse magnetic ballasts specially ordered to operate at 208v instead of 240v, or if you already have a Hydrofarm ballast, consult a certified electrician to rewire this for you. |
| Q: | Are my ballasts Generator-Ready? |
| A: | All of the ballasts we sell are generator-ready, except for the UltraGrow E-ballasts. They are not recommended for use with a generator. Generator Ready ballasts include: Xtrasun Ballasts, Phantom Ballasts, Nano Ballasts Super Grow Ballasts |
| Q: | I have a 1000W ballast, can I use a 400W or 600W bulb in it? |
| A: | As a general rule, ballasts can only be used with bulbs that are of the same wattage rating. A 1000W ballast can only be used with a 1000W bulb, a 400W with a 400W, etc. |
| Q: | Can an HPS ballast be used to power a metal halide bulb? |
| A: | This is never recommended, the ballast and bulb type (wattage and HID bulb type) must match. Convertible ballasts, however, can be switched between MH and HPS modes. There is also the option of using a conversion bulb. This is a bulb that is designed to produce a MH spectrum on a HPS ballasts, or vice versa. Phantom digital ballasts can ignite HPS or MH bulbs, except for the 750W model, which is meant only for HPS. |
