Power Surge Protection – Generator Ready * Standard surge protector or circuit breaker is available with every iPower Digital Ballast * 8 ft heavy duty power cord included* *NEMA 6-15 (240 V) power cord sold separately Dimmable Lighting Control – 50%, 75%, 100% Power Level * The dimming knob changes the desired power level, changing output and power consumption. * Dimming control is only available after the lamp reaches operating voltage to ensure proper mixture of the ses within the filament to ensure a steady spectral output and color temperature of the lamp. * Best lumen-per-watt-per-dollar lighting system on the market Frequently Asked Questions: --------------------------- Q: How many s can fit under a 4' x 4' (16 sq. ft.) area? A: The a of s that can fit in a 4' x 4' area is completely dependent on the size of the s and the size of the pots used. A five gallon pot is about 12" in diameter on the bottom, which means you may have up to 16 pots in a 4' x 4' area. Q: Can a lower wattage lamp be used with a higher wattage iPower ballast, and vice-versa? A: Different mismatched wattage lamp and ballast per light fixture may cause premature ballast and/or lamp failure, and is not covered under warranty. Please use the same paired wattage lamp and ballast per light fixture; the dimming feature is designed for the purpose of a lowering lamp output when needed.
