Do they turn on when not placed in water?

Yes. There is a little button on the bottom that turns them off and on. They are very pretty.

Yes they do. There is a button on them. You press it and you can pick the color. If you want, you can place in water but you don't have too. :-)

I did not put them in water at all. They will change colors based on the setting you have them in.

I haven't submerged them, but I've been in pretty bad rain... The lights themselves seem like they'd be ok. They have rubber seals, but the wiring would need to be properly prepared.

Correct. They come on automatically at dark. You can shut them off with a switch on the back and keep the battery charged.

Since they are battery operated, I have not tried to do that... altho that would be beautiful if it worked. There are openings in the bottom which the switch is and the batteries go, I think if submerged in water may null the battery and LCD lights. Good Luck!

No trick. Room just needs to be dark enough for them to turn on. It works off a light sensor. They don't just turn on when you plug them in. If the room is dark but they won't turn on then they're defective and you should return them.

No, no turn on or off - you just plug them in and they heat up, unplug to shut off.

Hi, No, they have to be plugged in to light up and then unplugged to shut-down. I wish they did have a light sensor switch. On the other hand, it would be something else that could go wrong and prevent the system from lighting up if it malfunctioned.

Yes - but if you turn them on before the sensor thinks it's dark, it will come on for 10 seconds and then turn off.

Hi. Nope. They stay on, but during the day, you can barley notice them.. And they use almost no electricty either, which is good

Yes, do not turn it on before it is in they water and shut it off before it comes out of the water

I haven't tried, but I assume no. They have batteries in them and would no longer work if you submersed them I would guess.

they do have an on/off switch, however; they come on automatically at dusk - they are lovely. I have had to replace one, but they are still worth it.

No, they don't turn off during the day. But you don't notice them when it's light out, and they use very little power.
