Hooked up the new hps and found something that i cant quite figure out. Im running an 800w genny and 3 150hpf's. When i bought the lights i expected to have to fire each one up seperatly due to the amps. (2.4 start up each light=7.2) and being an 800w genny should only handle 6.6amps All lights will start up same time and the genny never skips a beat or has any sign of struggle......and ive heard it struggle before...purrs like a kitten. Any ideas as to why this may be?
