Hydrofarm, Inc. Ultra Grow 600W E-Ballast w/600W Bulb Combo PMEBC600

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* Ultragrow Electronic Ballast with 600w Bulb (PM600S) • Safety Certification: CE, FCC, UL, cUL • Available in 1000 and 600 wattage • Five year standard warranty • Dimmable: 100%, 75%, 50% & Super Lumen • Dual Input Voltage: 120V & 240V • Compatible with HPS and MH lamps • Patent-pending soft dimming technology • 5% higher lumens @ "100%" output compared with traditional magnetic ballasts • 10% higher lumens @ "Super Lumen" output compared with traditional magnetic ballasts. • Technical Specifications Rated Voltage: AC 100 ~ 260 V Input Frequency: 50 ~ 60 Hz TA: -40 ~ 50ºC CF: < 1.7 PF: >=0.99 THD:
