No - A t-8 is a flourescent fixture. You will need a ballast and a socket set for the HID (high intensity discharge as in the HPS or the MH) bulbs. They sell replacement bulbs but not the fixtures. The fixtures and ballasts are specific to the wattage of the bulb. The bulbs are the cheap part of HID lights. You can do a search for HPS (high pressure sodium) and MH (metal hallide) systems and you will see what I mean. Figure out what type of system you are going to run and purchase parts or the whole system and then the bulb. Some systems come with a starter bulb.
