These ballasts are brand new. havnt even opened the boxxes that they came in. they are 1000w metal halide or high pressure sodium. also since theyre digital you can pug them into 220v or 110v without the need of any switches. same with changing bulbs from blue to red. Its plug and play. They have sun system plugs to plug directly into your hood. no need for any wiring. they are also power saving since they are digital. about 10% savings when run on 110v, and 20% savings of power when run on 220v. I am selling these only because i do not use indoor equiptment anymore. And i have a loan to pay to the bank. $200 a piece FIRM. There are 2 of them. and i need to sell ASAP to pay off my debts. Thank you, .
