it is common to cut up a heavy duty extension cord and wire the female end to the ballast and the male end to the lamp socket this allows you to just unplug the socket from the ballast if you ever needed to. while you wouldnt want to have an excessivly long cord lengths of 10-15 ft is often used.
bejay Reviewed by bejay on . REWIRING 400W HPS . My HPS has the ballast in the hood, which I want to seperate for cool tube purposes. Theres a blue and a white cord running from the bulb socket to the ballast. The white one is thicker, or more insulated. Can I just lengthen those two cords with just ordinary cords or are they both different? Will I kill myself? I know very little about electricity... Rating: 5
