Review on Creatrek Submersible LED Lights - Color Changing, Ideal For Underwater Pools, Campouts, Garden Vases, Fish Tanks, Fountains, And Bathtubs (3 Pack, RGB) by Devin Tanner

I purchased these lights for my koi pond a couple weeks ago. I finally used them last Saturday evening during a outdoor get-together. I removed them from the water at the end of the evening. The following morning they were already showing corrosion/rust. I opened them to remove the batteries and all three lights had water inside. I sealed them tightly, but still water got in. They looked nice and had a variety of available colors.
