These LED strips are the coolest thing I have ever bought.  It comes in a spool and you can cut the strip to fit whatever length you need.  It comes with a remote control so you can make the strip change colors more or less often, keep it on one color, or have it flash different colors.  The LED is very bright and would be great for parties.  We put ours on our patio for parties since they are also waterproof.  They are easy to hang since it just uses 3M tape.  They are easy to remove and add more strips to them as well.  These LED strips would be great for bars, kids rooms, parties, pools, anywhere you want to add a little fun.  I highly recommend them!
