how do I light a large room with no windows, just indirect light from the door?
If you do not want to do any construction, the best way IMO is to use lights flaring up in each corner. Buy them with opaque and a very material reflective interior. The light will be turned toward the ceiling and reflect from the ceiling down into the room. Paint your ceiling a bright white to reflect more light. http://www.lampsplus.com/products/floor-lamps/Type_Torchiere-Type/ The disadvantage of this option is that most of these halogen lamps which run very hot and can heat your room and make it uncomfortable especially in a room without windows. Search halogen alternatives. I think it is a new light intensity fluorescent high. Well, then You Get the dead, a fluorescent glow worrying. http://www.shop.com/+-a-torchiere+lamps+fluorescent-p38388941-k36-st.shtml
