Last updated 08-12-07

The Light-Up Coaster is...well...a light-up coaster. That is, when you set your drink on it, not only will it protect your precious apothecary table (the one you may have purchased at Pottery Barn like they did on the TV program "Friends") from those obnoxious white rings, it lights up your drink.

It has three LEDs in it that shine up throgh a transparent, textured diffusing window, and they come on automatically when you set a drink on it. The LEDs don't just run constantly; they fade in and out to give your drink a color-changing, glowing effect.


To use the The Light-Up Coaster, just set it down on any flat, hard surface, and set your drink on it. The LEDs will automatically come on when the drink is on the coaster, and automatically go out when the drink is removed.

To change the batteries, turn the coaster upside-down, and unclip & remove the three little battery doors. Set them aside.

If necessary, remove and dispose of or recycle the three AAA cells from the compartments.

Insert a new AAA cell in each compartment, orienting it so that it's flat end (-) negative faces the spring for it in its compartment.

Place the battery doors back on so they snap shut and are flush with the bottom of the coaster, and be done with it.

This is a light-up coaster, not a flashlight designed to be carried around, thrashed, trashed, and abused. So I won't throw it against the wall, stomp on it, try to drown it in the toilet bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannonada (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large display or with a handheld wand), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that flashlights may have inflicted upon them.
So this section of the coaster's web page will seem SIGNIFICANTLY more bare than this section of the web page on a page about a flashlight that was born to be a flashlight.

The "green" LED is actually an original cemistry yellow-green LED, not an indium gallium nitride (InGaN) emerald green LED.

Washing instructions were not furnished with the coaster; best suggestion I have is to wash it with a damp cloth (not a dripping cloth, but one that has been wrung out!), and then dry it off with a paper towel.

The LEDs are not as bright as I thought they'd be; having the unit actually light up your drink would require that it be used in near total darkness.

Test unit was purchased on the My Virtual Zone website on 07-15-07 and arrived on the afternoon of 08-09-07.

Product was made in China.
A product's country of origin really does matter to some people, which is why I published it on this web page.
