I also have a new sewing space although not as large as yours. I didn't start from scratch; it had been a bedroom previously. But I do have two windows and plenty of natural light during the daytime. Night time is the challenge. I use compact fluorescent bulbs in 5000 or 6000 color temperature. I have seven bulbs between 60 and 75 equivalent watts each to use at night, but I find that it's still not enough. What I have decided to do is install track lighting all the way around the room. This way I can move the lights over each station in the exact amount I need. The type of bulb is really a personal choice. The key is brightness and near daylight color temperature. I personally need limited task lighting because of the brightness of the lights on my sewing machines. But if your machines don't have very bright light you may also need task lighting at each machine. Hope you find the perfect combination for you!
