LED ice cubes are the easiest way to make a punch bowl, centerpiece, or bathroom display glow. Floating LED ice cubes for events and waterproof glowing cubes in bulk are a staple promo and event item, available in steady or color-cycling modes. This guide gives bulk buyers the specs to brief a supplier and get an accurate quote.

Material & waterproofing
The PS shell is sealed and waterproof, so the cube floats in drinks, pools, and vases. It is sold as a decorative floating ball / bathroom accent as well as a drink garnish.
Sizes
Two square sizes — 2.7 cm and 3.5 cm — let you mix scales in one display. The 3.5 cm reads best in a punch bowl; the 2.7 cm suits individual glasses.
Battery — sealed, not replaceable
These use a sealed AG10 cell that cannot be replaced by the end user. Battery life covers typical event use, but plan to treat them as single-event or limited-reuse items. If you need a replaceable version, ask in your brief — we can confirm availability.
Light modes
Choose single-color steady for an elegant look or 7-color RGB flash for party energy. (Note: some listings show a water-sensor variant that activates on contact with liquid — confirm the exact function when you request a quote.)
