I've been reading about how you should have a light for your TV when watching movies in the dark. I just got a new 27" TV for my bedroom, and will be watching it in the dark quite a bit, should I get a light? The TV is in a normal entertainment center. What kind of light should I get? I'm looking for something cheap, so would getting a fixture and light from Home Depot be my best route? Also, where exactly should I put the light? Thanks.
