Mounting dimensions: 9-Inch L x 0.9-Inch W, Mounting slot set 0.3-Inch apart. UltraMax ballasts have a lamp-friendly low-lamp-current crest factor and virtually "read" and adapt to incoming voltage. Parallel lamp operation keeps the unit maintenance easier to manage, if one lamp fails others will stay on. Active current regulation independently controls current output to each lamp, ensuring lamp life is not reduced should another lamp fail in the circuit. Ballast factor rating of High 1.15 for high power, high bay light output, ballast factor rating controls light output and wattages of each lamp, a lower BF will reduce light output and wattage of each lamp, meaning more lamps would be needed to achieve a certain foot-candle level in the same area. Unit provides anti-striation control, auto-restart functions, and is thermally protected against damage. Ballast has a cold minimum starting temperature of -20 Degree Fahrenheit. UL Type CC rating provides protection against arcing in electrical components. Less than 68 KHz lamp frequency, EAS system friendly. UL Type 1 Outdoor, UL Type HL, UL Class P listed, CUL listed, ETL NRCan, NEMA Premium, and ROHS Compliant - Industry standards for safety and performance.
