Does light work without water being on

No, the light is powered by the water. There is actually a slight hum when the water is on due to this.

No. Evaporation will collect on the lights. There's no protection on the lights to keep water off the electronics

Yes. The light strips are in protective tubes, so water can't get to them. I have 4 of these fixtures, all on open top tanks. :)

Afraid not. It's a simple circuit connected by water. So it's either on or off. It's fairly sensitive.

Let me first say that if Amazon sends you a light that works will be a small miricile. The sent me 2 used worthless lights. Let's say they work just for kicks and grins. If you put it out in the weather water will get in and not good things happen with water and electricity. The controls are on the bottom and it's designed to have the water flow with gravity.Good luck.Larry H.

No, but we leave ours on since we live in a very humid place & water condenses on it. We love it on all the time as a house night light. We have a big round one.

The light was very faint on mine. Just plug in after submerging. Worked great though.

As far as I can tell, no. You need some type of audio going for the water jets to react. The lights turn on as soon as there is power though.

The lamp was bought for my daughter, but she has not mentioned anything like that. She seems to keep it on most of the time also. I actually looked at it yesterday while there and I did not notice any water underneath it.

No, its hydro powered so just the water running through when its on makes the lights work. :-)

It comes on when it is heating so that the water is maintained at a consistent temperature. The heater does not run constantly however and that is why the light goes off.

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, you can turn it on with light or without light. The light can be turned off and it still operates!

I just got this at Christmas, but my understanding is that it works indefinitely. The light is actually powered by the water, so it should work for a long time.

Yes. The light toggles through various colors and gives the option to have no light.

Yes. There is a switch for the light, and a separate switch for the fan so that they work independently. So you could have the light on without the fan, or the fan on without the light, or have them both on at the same time.

Yes, lights have to have power. However you can dim lights to nothing through the app.
