Will this 400W HPS work?

  1. You wish it were as easy as just buying a bulb. For nearly any HID light, you must have a ballast. A ballast regulates the electricity going to light. The ballast itself is usually about $100-300 depending on the quality and whether it's digital or analog.

    So $20 for the bulb, say $100 for the ballast and another $30 on a crap reflector. You're not doing yourself any favors by buying everything individually unless you find some killer deal on a ballast and reflector.

    HID grow lights aren't just expensive for no reason
