Multi-volt Instant Start T8 Ballast will accept up to 1 F32T8 lamp. Accommodates multi-voltages from 120 to 277-volts, extra versatile for your unique projects. Anti-striation circuitry helps to eliminate and prevent the spiraling effect from lights. Active current regulation independently controls current output to each lamp, ensuring lamp life is not reduced should another lamp fail in the circuit. 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. Energy saving high efficiency instant start electronic ballast, more than 90-Percent efficiency. Unit provides anti-striation control, auto-restart functions, and is thermally protected against damage. T8 ballast sound rating: Class A (20-24 decibels). Ballast factor rating of Low .77 for low power maximum savings, 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. Parallel lamp operation keeps the unit maintenance easier to manage, if one lamp fails others will stay on. Ballast has a cold minimum starting temperature of -20 Degree Fahrenheit. UL Type CC rating provides protection against arcing in electrical components. UL Type 1 Outdoor, UL Type HL, UL Type CC, UL Class P listed, CUL listed, NEMA Premium, and ROHS Compliant - Industry standards for safety and performance.
