hey all, i just got a mh 150 w bulb from my lfs and a ballast from a local electric supplier. i wired them up last night with the help of my brother who is an electrician. we plugged the unti in and nothing happened.i never saw a filament in the bulb. i think that it is a bad bulb. my ? is do mh bulbs have a filament, or do i just not have enough voltage to fire it up. this is a totally diy project and need some input
