Well, I have to say that I have not put them up yet - because (as you can see in the first pic) they are jumbled mess and I think it's going to take a while to get them all laid out and then put up. The lights are RGB-IC which are good for holiday lighting. The cord part is only 8 ft in length, so you will need to adjust where you put them to be able to plug them in. They also come with tons of little screws so you can secure them well. There is no information on the brightness though. The LED lights should have a lumen number, but I cannot find anything in the description, which leads me to believe it might not be very bright. So, I will need to get them up and post a pic of the brightness and colors.
