you need to have a ballast with hps lightsman i definitely need some help. I bought a basic clamp light with porcelain socket that holds up to 300w of light power & also bought a 150w High Pressure Sodium light bulb. When tried to put both together and plug in my light bulb, it did not light up. Is that the wrong light bulb for that clamp light socket??? If so, what other kind of light bulb should i buy to replace it in order to have enough light on my plant? Whats the best alternative light buld to use for it?
