Does it have thje ability to run completely DARK (NO LIGHTS) while sleeping? How many hours will it run before it runs out of water? Auto-Shutoff?

You do not have to use the light. I never timed it, but you can adjust for times, just never used that feature. I have had very expensive glass atomizers in the past when they first came out, and this one is less vulnerable and delivers a once aromatic scent to the room.

DON'T get this unit!!! Mine broke within 6 mo. I bought a H2EO, I think bought thru Amazon about a mo after getting this one. It is awesome! Have had almost 2 yrs. It can rotate between 4 lights and YES the lights can be shut off. It has many settings and very good manual. I also remember not much price difference. Again I would NOT buy this model. I love this one, very dependable.

The water tank is colored blue and semi transparent but not lit. The lights are from the control panel which are blue but not bright enough to disturb sleep.

I've run my previous one for twelve hours or longer. However, I burnt it out when I let it run dry overnight. I'm sure it would have continued to run, had there been water to pump. The unit is so good, for so little money, I bought another.

I usually fill it to the fill line inside the unit (about a cup of water) and run it until it shuts off. That takes about 4 hours. Unfortunately, the unit doesn't "just" shut off. It alternately shuts off and turns back on for a while before finally stopping. The repeating off/on noise is noticeable enough that it wakes me up when using it at night.

The light can be turned on or off while operating. The power light is a bit bright though and stays on until it runs out of water. Hope this helps!

I fill mine to the water level or just a tad higher, i.e. like 1/4" or less. And it runs I would say between 6 to 7 hrs and then shuts down; after it shuts down it cools down to room temp...or cold. So mine does shut off by itself when the water runs low.

The light can be turned off or on bright or darker versions of red, green, blue or white. Super easy to clean and runs for 180 min before automatically shutting off.

Yes, in the sense that one can set it to run (in one hour increments only) from 1 to 12 hrs or "C" which means run continuously until it runs out of water.

No the auto shut off is built in and shuts off after 2 hours. I usually fall asleep with mine on so it's perfect for me, but you can just click it back on.

Depends on high you set it. If I leave it on low, it will run overnight for 2 nights. If I turn it up halfway to high, it is near empty by morning.

no night light - just a small red light when it's out of water and a green light when it is on.

The light has a photo cell that turns it off totally in daylight and only on when it detects motion at night. Mine never stays on all the time. My light did fail once manuf said water must have gotten inside but got it replaced under warranty. If yours is less than one yr old call them

Yes, it has a timer to run up to one hour. However, you must be awake to release the pressure when it shuts off. That is not automatic.

No, it auto shuts off after about 20 minutes. It runs off batteries with no rechargeable plugs, so it conserves its battery life this way.

No. It just turns itself off. If you need the diffuser to run all night, you can change the settings so the contents of the reservoir aren't used up as quickly.

I run mine on the intermittent setting (it runs for 6 hours)... approximately half the water is gone. I always reflll it before starting it again, so not sure exactly. Based on what I've observed, maybe 12 hours? It automatically shuts off after 6, or 3 (if on constant).

It has only one setting and yes, it does run out of water in about 3 hours. It doesn't hold that much water to begin with though. It does keep the water cool. There is no heat whatsoever created in the unit.
