You can get 2 oz from a 100HPS its been done. I never tried to put one of those in a "regular" socket but I thought about it. The fixture you buy at the home improvement store will have everything you need except a power cord. As asryda said it is easy to wire.There are usually parts that will shock/electrocute you so look it up first.Dont handle any part of the thing when it is plugged in.And do not touch any part of it with liquid (sweat,water,etc.)the oil from your hand will leave a residue and can cause almost any High Intensity Discharge bulb to implode/explode.I can get 150HPS for less than $100 USD.The more you learn the safer your fun can be.good luck.let us know how it goes.
