Does this need to be used only in a dark room?

It is best used in a dark room or one with very low light. On the ceiling it the night sky. Suzy L

Yes, but it's garbage. The batteries will die on the planetarium setting within less than four hours a on 4 AA batteries. On the other side, the image stills end up VERY small, even from the floor, and aren't very clear. I gave it to a friend with an age appropriate child and they weren't fans either. Little boy got bored with them after a single viewing.

Yes it works best in a dark room. You do not see the lights during daylight.

Could arrange the device so that it doesn't get too much light from the lamp but it's effective when the room is dark -- we simply moved the lamp timer to a different room.

It's considered "dusk-to-dawn" due to that's when it would operate when set outside. It would work indoors at any time. I'm even tempted to buy more for the closets I keep forgetting to turn switches off :-)

In a dark room, it's about the equivalent of a candle with a thin wick. (Yes, I've measured this.) If your eyes are adjusted, it's enough light to keep you from killing yourself tripping over a chair or large dog. However, there are better ways to light a phone area without sucking down so much power. 3 AAA batteries will last a lot longer in a device designed specifically for area lighting. -tkh

Yes, enough so I can use it in the dark if necessary. There's a key to turn it on and off.

Yes, they only go on when the light is quite dim. It doesn't have to be totally dark. I was skeptical at first, these are surprisingly useful. I just ordered a second set for a different location in our house.

You need a dark room for the best picture. When I had this projector I tended to only use it at night.

It can be used in a partially lighted setting. My daughter has the bathroom light on and a nightlight. It doesn't affect the light. You can still see it very well.

When ambient light is low the unit lights dimly and stays lit dimly giving low illumination. Once activated by motion it becomes much brighter. This would of course conserve stored energy. I did not see anything in the manual that mentioned the ability to set the unit to provide light all night long without motion (keep in mind I'm operating off my memory as I no longer have the manual). I'll post again on the unit after its been in use for > 1 month to let you know what reliability is. It has operated for > 1 week without problems.

Yes but keep in mind its only about 50 lumens which means it will not do well I bright environments... in order to look good it needs to be in a dark room.

No - I don't believe it would be bright enough. This requires the room to be very dark.

Since the timer activates with darkness I would say no. You could turn the switch to "on" and plug it into the lamp timer. Of course it won't show as brightly as it would from a dark room.

No. I actually got it for the opposite reason. I wanted to allow light into my place without sacrificing privacy and it does that quite effectively. If you are looking to darken a room, this is not what you are looking for.

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.

You will only see red LED's when in a dark room. The sensor does not turn them on until it senses darkness. Additionally, your cameras needs to be 850nm to use this unit.

Hello Steve, this is not a good choice for low-light conditions. It only works in daytime, or indoors with good lighting.

yes if you have lights of some sort on. does not work in total darkness. exp lamp
