Waterproof structure, matte surface, blue sealing ring, 4 suction cups on one side, it becomes not only more practical and durable, but also more beautiful. CAUTIONS:Suction cup can be used in both air and underwater ONLY ON FLAT AND SMOOTH SURFACE. Clean the surface before attaching.【IP68 Fully Waterproof Design】 Compare with normal pool led lights, we updated our mould with adding a thicker sealing ring which is much easier to close than others in the market, thus it's fully waterproof underwater. (Please close tightly enough to avoid leaking) The battery box can still keep completely dry to avoid internal corrosion even after a long period of underwater use.【164FT/50M Floating Color Changing Lights with Remote RF】 Unlike the infrared remote (IR), Radio frequency remote (RF) is much more stronger, IR remote can only control within 2FT, but RF remote can remote max 164ft/50m in air, 9.8ft/3m underwater. We use RF tech for better remote sensitivity, you don't need to worry about signal being blocked by water, walls barrier etc in large deep pools.【13 LEDs Color Changing Shower Lights with 16 colors】 Splonary submersible pool lights are made of 13 premium led beads, it’s 3 times brighter and more vivid than other 10 led underwater lights. 16 steady colors (like white, red, green, blue, yellow, purple and more), 3 color changing modes (flash, fade, smooth), 3 timer button (2H, 4H, 6H). Just one remote, you can control all the pool lighting and create a romantic atmosphere.【Easy to use】 Led lights for shower is powered by 3 x AA batteries instead of AAA batteries, which lasts 30-48 hours, 8 times more powerful and lasts longer than AAA battery(6 hours).
