Some ballast like Work Horse will run different lamps. Your ballast guessing with the serial # will run 4 32 watt T8 or total 128 watts. WH#7 will run 220 watts of any lamp. The only way to see if this ballast is working correctly is with a Lumen or PAR meter using your ballast and then a ballast made for T5HO. Since your ballast is not UL Listed for T5HO I would not recommend it. And you are correct program and rapid start ballast help lamps run longer than instant start.
