Bought for wedding center pieces
We used these lights for our wedding center pieces we placed them in jars filled with those water bead and WOW it really made them pop the color is bright and they reflected on the water beads well. One light was enough for a half gallon mason jar filled with beads. For time purposes don't forget to remove the paper between the battery beforehand so when you have a team of people helping you set up it's one less thing for them to do. All my lights worked when I tested them so that was a plus.
ProsReally bright only need one for a half gallon mason jar full of water beads
ConsMake sure to remove all the little paper pieces between the batteries
