That is a security bulb. The housings and ballasts are sold at hardware stores. You should know that the spectrum of a security HPS and an agricultural HPS are not necessarily the same. I have run a 70w sec lamp before and while it does grow plants, it grows lanky plants compared to a better lamp. And the reflector is totally wrong. For the cost of a security light, you can get an El Cheapo setup from a discount grow supply vendor. I'd recommend saving your money and getting something better, like a 250w agricultural ballast-reflector-bulb set. Just my 2 cents.

Need some help I just received a 70 watt hps bulb from a friend of mine and was wondering if anyone knew if there is a way I could find a cheap ballast set online? And if so, will it come with wiring instructions or will wiring be easy. The most important question is if I do buy a ballast kit for it will I be able to wire it so I can plug it into any household outlet? Rating: 5
