When you first pick one of these up, you might be tempted to fill it up out of the faucet and drink out of it. Don't. Shake it once or twice and set it down instead. You'll be rewarded with a gentle, but colorful light show from the goodies hidden inside. The Zzz...Lite is designed to be used as a bedroom light, a nighttime sleep aid, and a handy light to take to the bathroom with you when nature calls at 4:45 in the morning.


The Zzz...Lite is very easy to use. All you do is pick it up & give it a shake, and then set it back down. You'll be rewarded with a colorful, color-changing light show that runs for approximately 19 minutes, slowly decreasing in brightness until it simply goes out. Automatically. You'll hear a little tinkling noise inside when you shake your Zzz...Lite; this is perfectly normal. It's from the "shaker switch" in action.

(IMPORTANT: This photograph is of the Zzz...Flame)

If you just shake it once or twice, the Zzz...Lite will do this automatic light show for you; but if you need it to be as bright as possible without flickering, shake it 5 or 6 times, using a long, slow arm motion - then the Zzz...Lite's LED will come on with all three dice (light-emitting chips) at full brightness and stay that way until you shut it off.

To turn the unit off anytime it's on, just shake it once, and out it goes.

To change the batteries in your Zzz...Lite, unscrew the black lid. You'll find the battery pack and the electronics mounted to a white round disc.

If necessary, you can jiggle the "guts" out of the black cap. Remove & dispose of or recycle the old batteries, and insert three new AA cells into the holder with the flat (-) side of each battery going toward the spring in its compartment. Place the electronics back in the lid, and screw the housing & lid back together.

The Zzz...Lite signals it's time for new batteries by displaying a reddish color when you first turn it on. With nightly use, a set of good alkaline batteries should last up to several months.

I stole the batteries out of my Zzz...Flame for the Zzz...Lite; however it does not display that telltale reddish color when turned on, so I believe I still have a valid test here.

The Zzz...Lite is definitely unusual, but is also quite nice to look at after dark. Never mind that it was built into a plastic water bottle - this turned out to be the perfect housing for it. The white, somewhat transluscent plastic of the bottle diffuses the LED light just enough (more so than in the Zzz...Flame, and it also keeps the electronics & batteries out of the elements. So if you want to take it camping, go right ahead.

The Zzz...Lite appears to be water resistant, seeing it's made out of a water bottle. :) If you took it to the bathroom one sleepy night and it fell in the loud chair (toilet), just wash it off. As long as the black lid is on tightly and the label on the lid is intact (insomuch as the label still covers the straw hole in the center), it should be water-resistant. You could also unscrew the cap & remove the guts, and then hand-wash the bottle if you're really that worried. Just make sure it's completely dry before putting your Zzz...Lite back together again.

Throw away that bottle of sleeping pills and replace it with a bottle of tranquility - a Zzz...Lite!

This is another video that shows the EternaLight Zzz...Lite in action.

O boy...a light changing colors!
So thrilling!! So heart-pounding!!! Actually, it kinda makes you want to beat the living tweedle out of one of those suicide-resistant prison combys with a hairbrush, doesn't it? :-O

That music you hear is zax from the pee-cee demo, "Delusion" by Sonic PC and from the demo, "Crystal Dreams 2" by Triton.
This product is not sound-sensitive; the music may be ignored or even muted if it pisses you off.
I may be a metalhead most of the time, but not *ALL* of the time; the choons in this video are also very pleasing for me to listen to.

I cannot provide either video in other formats, so please do not ask.

Unit was received on 01-21-05, and testing is continuing.

I made an observation that if there is an earthquake of sufficient magnitude to knock the unit off your nightstand or headboard, it will come on by itself when it hits the bed or the floor, serving as an automatic emergency light even if the quake knocks out power to your house. Those living in Seattle, San Francisco or Los Angeles can appreciate the Zzz...Lite for that feature in addition to its other uses.

Note: Light makes a slight ticking or tinkly sound when shaken - this is normal and does not indicate a problem with the unit.
