An Xtrasun convertible ballast means extra flexibility for your gardening. Use halide for growing, then once plants have started, switch to sodium bulbs for flowering.
- Convert from sodium to halide and back
- Dual voltage
- Works with Hydrofarm reflectors and most others
- Aluminum fins for more cooling surface
- CSA certified
Will my dual voltage 120/240V ballast operate on 208V or 277V?
Our Xtrasun and SG Lite 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, and Nano ballasts
I have a 1000W ballast, can I use a 400W or 600W bulb in it?
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. The one exception is the Xtrasun "Dial-a-Watt" ballasts (XTEDW-), which are meant to be used with the same wattage bulb as the dimmed setting (for example, use a 600W bulb when dimmed to 600W, etc.).
Can an HPS ballast be used to power a metal halide bulb?
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.
