Does it only work when in complete darkness?

I can see pet stains pretty well even with a room that is dimly lit, but it does work best with all the lights off. Even with some light still coming in the window though it works great

No, it works in dim light as well. I got this in the mail at 4pm when I got home from work, the sun was out. I pulled the curtains and turned off the lights inside, and it showed up. I have yellow shades I got from the "as seen on TV" shelf at Walgreens, they advertise to help with night vision. It makes all the stains glow brightly.

Well, let's just say "It works better if you shut the lights out"...but, It works well enough if you're trying to check a particular corner with most light off. You just need to get closer to the stain if the light is dim rather than it being dark.

I think it depends on the surfaces. The legs of one of my tables and my bookshelves glowed in low light. Depending on the surface (carpeting and walls, for example) might need total darkness.

I used this flashlight when it was mostly dark, but it wasn't completely pitch black. There was a little light coming through the window from the front streetlight. I'd say it was mostly dark...too dark to read, but there was enough to find my way around the house without the flashlight on. In rooms where it was pitch black (walk-in closet), the ultraviolet glow from puppy pee was much brighter.

On my carpets, I can see the dog urine stains with the light during the day as long as it is not in complete sunlight. You just have to hold the light a little closer (around 2 feet) from the floor. My carpets are all light to medium colors. I don't know if the results would be the same with darker colors, although I would expect it would be even easier to see the stains since they glow under the light and the contrast would be greater.

No, it's not backlit bright enough to type in complete darkness. What they meant by "backlit", is that on the top of the keyboard, it shows if the battery is fully charged, which is illuminated, but far from the degree to see the keyboard in complete darkness.

Night Vision works the best when it's complete dark. If you install camera in half dark environment, the camera IR LED won't completely turn on, that's the worse situation for night vision camera.

No, it comes on only at night when it senses motion, is quite bright, and goes off in less than 30 seconds. It uses 4 D batteries. We are extremely satisfied with the product. HMC

No, but you can reduce the sensitivity of the motion sensor AND decrease the amount of time it stays bright when triggered. So, the way I have it set, the light comes on at dusk at a low intensity and will stay on continuously until dawn. If you walk directly in front of it, closer than about 5 feet or so, it goes to full brightness, then if the motion is not triggered again, it goes back to the low brightness in about 1 minute or less. When set in this mode, at no time does it completely turn off, unless the batteries are really run down. When you first receive it, the batteries could be really low (mine was) and I thought at first it was defective, until I reread the instructions, and understood how it's programmed to function. The motion sensor has priority, meaning that when the battery gets really low, the light will discontinue the low intensity dusk to dawn mode, and save what power is left to turn on bright when motion triggered..... So be sure to let it charge at least one day in the sun before you turn it to any setting other than off. (Still charges battery when turned to off). Since I have had it it has always remained on until dawn, even with some really cloudy and raining days decreasing its ability to charge. Now if it's motion sensor gets triggered too often, I can see the battery maybe getting rundown..... It this happens you can use another trick I have used before....simply take black electrical tape and tape up a portion of the motion sensor. Covered by black tape it will NOT sense motion.

No, it only comes on in the dark (had this product for a couple months now, still HIGHLY recommend).

no, when plugged in it will only light up when there is a power failure. you can use it as a flashlight at any time when you remove it from the plug.

Yes, the lighing still shows. Not quite as bright as it would otherwise, but it works great in the dark.

No. When the power is on, it works as a light activated night light. When the power goes out, if it's dark, then the light actually increases in brightness.

You don't really need total darkness, but it works best in semi to complete darkness. You're better able to see small detail if you work in a darkened room with your projector.

I just checked... It does light up and will work in the dark.Thanks for your great question.

Yes works fine in a fully dark basement. You may have to wave your arm to get it to activate, but that would be because my sensor is between other things and has a small angle to pick up motion.

Pat, the light works with a motion defection sensor and has several time on settings. This is not a light that goes on dawn to dusk type. Settings vary from 1-15 minutes.I hope this helps you. I love this light.

Yes - the keyboard lights up around the keys. Works great for any level of darkness.

Without light on or with light completely removed? It works without light on

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.
