I purchased the same light setup. My ballast is a different style. It's a good one.
I believe the rule of thumb on how close is to use your hand as a guide. When it gets hot on your hand it's hot on the plants.
I have a small fan blowing across the bottom of the bulb to keep the heat off my plants. This maybe be overkill for you since your basement is cool. An experienced grower can tell you for sure.
Definitely use a fan to blow slowly on the plants in order to strengthen the main stem.
Good luck
