Multi Color LED Light up ice cubes with Push Button on/off and with 8 modes (blue, red, green, pink, aqua, lemon lime, confetti and a rotating combination of all 7). Each push of the button will change the color in steady on and the last setting flashes each color in rotation. Push Button cubes last longer and work in ice, unlike cubes with moisture sensors (which only work when submerged in liquid). When off, cubes are clear. FDA approved clear acrylic shell is sealed for safe use in beverages or in ice. Mix in with ice in your cooler for a very nice light ambience and also provide visibility inside cooler. Perfect for parties, events, or adding a playful touch to bath time. They are attention getters in cocktails and glasses of wine. They can be frozen to add some mild chilling to a beverage. Our cubes are sealed so that they are safe for use in drinks or in ice. Batteries cannot be replaced. Battery life is about 18-28 hours. They will last longer in the blinking mode vs. the steady on mode so the variation of lifespan is determined by how they are used. Since most typical events range from 3 to 5 hours, the benefit is that they can be used multiple times for multiple events before the battery expires.
