Had plans for a BIG coral display, but the wife got pregnant and shut it down. My office is now a baby nursery.

Brand new. Two (2) available. Comes with everything you need except the electrical wire. Never been wired, never been fired.

These ballasts will perfectly fire high-intensity discharge lamps (including specialty bulbs like a Radium or Ushio 14,000 Kelvin or 20,000 Kelvin metal halide light bulb) to manufacturer specifications. These can fire a high pressure sodium (HPS) or a metal halide (MH) lamp. Using these will get you a very accurate color temperature from your bulb. This setup would be ideal for coral tanks (aquariums) or for an indoor garden if you're wanting full spectrum lighting. They are designed to be operated on a 220-240 volt circuit at 60 Hz (220V, 230V, 240V). They come with ignitors, motor run capacitors, hospital grade NEMA plugs, and a hospital grade duplex receptacle (everything you need to light your bulbs except the wire). See details below. The ballasts are made in Slovenia, the ignitors were made in Austria, and the motor run capacitors were made in Italy. These are not Chinese junk products. For some reason I can't post links or images. I have photos available, as well as links to the brochures/spec sheets. Let me know if you're interested and I'll find a way to get you them. Thanks for looking.

Ballast (HID magnetic choke) info:
Part number: 20880891
Description: Tridonic OGLIS 1000W 140 220-240/60 140B194
Voltage: 220-240 volts @ 60 Hz
Country of origin: Slovenia
Magnetic ballast for 60 Hz high pressure sodium and metal halide lamps. Chokes with reversible thermal cutout: trigger temperature 155 °C. Lamp wattage 1000 W. Rated lamp current 10.30 A.

Ignitor info:
Part number: 20826280
Description: Tridonic ZRM 20-ES/B
Country of origin: Austria
The special feature of these ignitors is that the ignition voltage is generated without placing a high-voltage load on the choke. This ensures maximum reliability. Minimal self-heating, which in turn gives luminaire designers extra creative freedom.

Capacitor info:
Comar MK 450 70 μF (mfd, microfarad) capacitors
Rated voltage: 450 Vac
Rated frequency: 50 / 60 Hz
Capacitance tolerance: ±5%
Operating class: 400V - B 10000h 450V - C - 3000h
Climatic category: 25 / 85 / 21 -25°C / + 85°C
Case: Bottom M8 metal stud self-extinguishing plastic case
Connection: Double / single terminal tag 6.3 x 0.8 mm
Country of origin: Italy
Dimensions: 50 x 120 mm

Also includes 250V hospital grade NEMA plugs and a hospital grade duplex receptacle.

I paid $296 per ballast which included the ignitors. I separately paid for the Comar motor run capacitors (which I believe cost me $50-60 each). I also paid $17 each for the hospital grade NEMA plugs.
