I just ordered three 105 watts from the same place. There are two kinds of sockets that can be used for CFL's: mogel (e39) or the meduim (e26). The meduims are regular socket that fit normal bulbs. Yours are the mogul kind. Make sure to order mogel sockets and they will work fine. You should get 2700k and 6500k color temp. One is veg and the other flowering. Yours are 5000k full spectrum. You get better results if you get the right color temp for each phase. Mogel sockets are the way to go for you. Most of the higher watt cfl only can be used in the mogel socket, so if you plan on upgrading, you wont have to buy new sockets as well.
