Lighting a room the right way will add a richness to your whole experience: A soft glow under a bar, light emanating from crown molding reflecting off the ceiling or a back light for your TV viewing pleasure. It provides a nice glow to the room and, depending on the mood you are looking for, can be great for a nightlight or a party. These strips that you can easily string around a room or to the back of your monitor can be bought at retailers like Amazon (listed below). They are super cheap, but look pretty expensive and it's all something you can do on your own.
I have my TV set up with a nice white light, but you can also buy these in colors and changing colors. I have Jeopardy set up on my Firestick through Amazon Prime and it's fun to place with a group of friends with the added mood lighting giving it the enhanced game show quality. Have fun with it and feel free to comment if you come up with creative ways to use these that I haven't thought of!
