This thing is great right out of the box and does not need a lot of set up. Pull the plastic tab out the remote, plug this bugger in, use the remote to turn it on and bam! you have an ocean on your ceiling. I love that there are so many colors to choose from and you can adjust the brightness. You can also adjust if you want to stay on one color,We have a cathedral ceiling in our bedroom and this thing is definitely bright enough to throw it all the way up there. If you are into mood lighting, you need this in your life.
