I'd put them elsewhere and give them light for 18 to 20 hrs out of the day. Seedlings don't need a whole lot of light at first so any room and/or lamp that you can keep lit accordingly will do for the time being.
It sounds to me like they're ready. I go by where the branches snap as if "breaking" internally but they don't actually break into two pieces, if that makes sense. I'm no expert, though.
