Optional selectable dimming levels at 400W, 600W and 1000W levels. Boost your output 10% by switching to 1000SL. When changing to a reduced power option, the Slow Start Transition System in the Air-cooled gradually adjusts the input wattage so as to reduce bulb shock, increasing the life of your lamps.


Q:I have a 1000W ballast, can I use a 400W or 600W bulb in it?
A: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. *This does not apply to the dimmable Lumateks, which can use a 600W bulb if dimming switch is set to 600W, etc. The Dial-A-Watt technology inside Lumatek ballasts gives them the ability to power different wattage lamps on the same ballast. If you have a resin sealed Lumatek 1,000W ballast you can use a 600W, 750W or 1,000W lamp in it. If you have a new Air Cooled Lumatek ballast you can use a 400W, 600W or 1,000W lamp in it.*
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 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.
