Plasma will be much brighter in your home than at the store. When I have my 50" plasma on at night (in the lowest contrast mode), it produces enough light to light up the entire room like a lamp is turned on. If I put it on in vivid at night it would be like having flood lights on. There is a big difference between having a plasma on in a 100,000 square foot store with giant flood lights, and watching a plasma at home with 1 or 2 100 watt lights in the room.
