Meditation doesn't have to take place any specific place - not in a dark room, not in a place of prayer, not in an ashram. meditation can take place wherever is comfortable for you or available for you. I meditate in my condo, sitting on a pillow, close to the windows - whether it's light or dark outside doesn't matter. all you need to do is find a spot that's comfortable for you. sometimes I light a candle, sometimes I don't. Don't let meditation intimidate you! It's a personal practice that can be done wherever YOU are.
