We print your design in your choice of CMYK colors. The LEDs illuminate the entire coaster including your printed design when turned on. LEDs will not light up black print, but will shine through colors (white glows brightest).
The coaster design illuminates through a gravity switch on the bottom. The weight of a drink placed on top will initiate the lighting effect for an interactive experience!
The coasters are designed to be waterproof with 1 CR2032 batteries placed within the coaster (included). Gently snap the outer ring off the coaster, then open it up like a clam shell to access the batteries for replacement. Batteries last around 50 hours.
How long do the batteries last? 🪫
Typically the LED coasters can run for 50-54 hours of use before needing to be replaced.
How does "drink activated" lighting work?
We call our LED coasters “drink activated” as there is a button on the bottom side of the coaster that activates the light effect. When you place a drink on top of the coaster then the button is pressed, causing it to light up. As soon as you pick the drink up off the coaster the lighting will stop, and then resume once you put the drink back down again.
What color print options are available?
The most popular option is a white logo print on black background so that the LED light shines through the white print. You can print the logo or background any color you’d like, but the light does not shine as well through darker colors. We recommend colorful logos are paired with white LEDs for a true-to-color glow effect.
How big are light up coasters?
The coasters are about a 4″ diameter, which is standard size for a drink coaster. Most other LED coasters are made much smaller to fit within a car cupholder.
Are LED Coasters waterproof? 💦
Yes! Our LED drink coasters can withstand a drink being spilled on it. The battery pack is hidden inside the coaster with an acrylic exterior that repels liquids. Just don’t submerge under water fully – these are not dishwasher friendly! Wipe down to clean.
How do you replace the batteries? 🔋
LED Coasters are powered by 1 CR2032 button battery and is easy to replace in three steps:
- Remove the silicone ring around the coaster
- Open the coaster into two pieces like a clam shell
- Remove the current battery and replace with new one in same position, & reassemble. See here.
I am extremely satisfied with my order of led coasters. We ordered for my son’s Bar Mitzvah and all the kids were impressed
