Hydrofarm, Inc. Lumatek 400W Ballast w/ Lumatek 400W Bulb Kit LK400KIT

Frequently Asked Questions Q: I have a 1000W ballast, can I use a 400W or 600W bulb in it? A: No, 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. *This does not apply to the dimmable Lumateks, which can use a 600W bulb if dimming switch is set to 600W, 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 operation) 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 special type of bulb which allows an HPS ballast to operate a MH bulb or visa versa. *This does not apply to the Phantom digital models* Ballast • Unique graduated fin design for more efficient cooling • Completely pre-wired with popular BAREF lamp cord • *3 years full + 2 years warranty • Internal Resin coating protects components for long life • External breaker system protects against power surges • Completely silent Lumatek 400W High-Par Output HPS Lumatek's high-par output lamps are designed by the world's leading HID lamp engineers.
