Questions about growing lettuce indoors

We’re trying to become more self sufficient when it comes to food. I eat tons of lettuce. I grew it for years in California, but we’re in upstate NY now, and it’s either too hot or too cold. I remember people mentioning that they grew it in their basement here, and I have questions.

I just got some good lights, but I’ve never grown things like this indoors before. We have a fantastic damp, cool basement for it, so I know it will love the temperature. My questions are: how close should the lights be to the plants, and how long should the lights be on each day? I’d love to hear about your experiences!
