Glad I could be of assistance.
Are you getting the 2x2 tent? If you are, the light you had listed above looks fine for growing. Just pay real close attention to the distance away from the plant. Seedlings are VERY sensitive to to light.
I was growing with CFL before I got my LED so I still use the CFL for seedlings but that is a personal thing. The LED will work fine as long as you keep an eye on the plants.
Later in the grow, when you start flowering, you will need a fan and filter. The light will produce heat and you need some way to control it. The flowers also produce a lot of smell and unless you want your entire place smelling like pot for a while, I would get one like this. This one is nice as it has a controller to control the amount of air that goes in and out. It also helps control humidity in the tent. A 4" fan is more than enough for a 2x2 tent.
I kind of specialize in growing in small spaces, my grow box is only 18"x16" x48". I still manage to get good yields. This is my current grow.
Hope this helps. Jerry
