How sensitive is the sensor to darkness? i.e. does it stay turned on all afternoon like some, or does it only come on once very dark?

I think it's a bit like Goldilocks (of "thee bears" fame) would want it... it seems just right. It doesn't wait until total pitch darkness to illuminate, but when there is sufficient ambient light, it shuts itself off. It does it well enough that it seems natural and unobtrusive to us.

It is about a good as they come. I have it installed in a bathroom and it's on when the room in dim and turns on within 5 seconds of turning on the light and stays off. It does not flicker on and off around the threshold of darkness. Some of the cheaper one will turn on and then light up the room to make it think that it's bright enough to turn back off, only to repeat very quickly causing the flickering on and off; this one does not do that. I only wish I had bought it years ago. You won't be disappointed!

Ours is in a dim hallway with no direct natural light, and it is off during the day. It only comes on at night when none of the bedroom lights are on and the hall is dark. It does exactly what we wanted it to do.

Sensitivity to darkness is excellent. I comes out when light is very low, but not pitch black dark.

I have mine set up on a stairwell that has a skylight above it, so it's getting the full amount of sunlight. But it works great. It turns on and off exactly when I would want it to.

We have fairly dark hallways and it stays off until dark. No problems yet and we are pleased.

Mine are pretty sensitive. They are all in hallways. As soon as the afternoon sun is gone, they all turn on.

Yes, it turns on during some time of the day if it's in some dark area. As for mine, when a person passesby it, it turns on only if it's really dark during the day, mostly in the early morning and late afternoon. When it's cloudy outside, the light turns on too when a person passes by it. It doesn't turn on during most time of the day.

This unit has a photo light sensor. You just set how long you want the lights to stay on for. So auto on at dusk and off base on how long you set the duration for.

The light will not stay on continously once the motino sensor is tripped, unless its malfunctioning or running low on battery power. I found it says on for 30 seconds, then turn off regardless if you are in front of the sensor moving around. It will then to take about a full second before it will come on again if you move around the sensor.

I bought two (2)... one works just fine as adjusted. The second one just started to comes on days and night and stays on for 3/4 seconds. I tried adjusting the sensor and time duration with no positive results. Trying to contact All Pro for resolution.

Yes, the easiest way is to plug it into day/night sensor plug. That way it comes on automatically in the evening and goes off at dawn.

Mine goes off once it is very bright outside. It stays on well after dawn. It stays on when it is bright enough to read a newspaper right next to the sensor, adjust sprinklers in the hard, drive a car without lights. I emailed customer service about this issue and their answer was: "There are no adjustments to the photo sensor, if the sensor is located under the eave it is possible that it's not receiving enough ambient light to turn it off. Try installing some reflective or mirrored tape close to the sensor to see if that will direct enough light to the sensor to turn it off." I am going to try the tape, but it does not work as promised, and it is an expensive unit. Not happy. Mine goes off once it is very bright outside. It stays on well after dawn.

It can be set to come on dusk to dawn, or set to come on when it detects motion. It can also be set to stay on for 1to 20 minutes after it senses motion. The sensitivity to motion can also be controlled, but that takes manual adjusting. All controls are on the unit, so if it's mounted up high, you need to go up and down the ladder until you have te settings to your preference. Overall, it's turned out to be the best motion sensor light we've installed.

The camera does a decent job once is fully dark, but during the change from day to dark is a little bit washed, also sometimes the motion sensor triggers with put actual motion with in the field of view. I am currently twiking the sensor levels

The program (on/off) is set by the time of day for a seven day period. If you know the time of sunset you could program in that time, but there is no light sensor. I previously had put sensors on my lights, but they were not that "accurate" and after a few months they quit working all together. Being able to turn on the lights at a specified time is much better for me, although some reprogramming will be required as DST kicks in and the hours of sunlight changes. Hope this helps.

Yes the day light sensor is disabled by default, just motion sensor is enabled. The daylight is an additional setting you can enabled if desired.

I agree that the camera does not work well at all in the dark but is fine in daylight and hope that will be upgraded or improved in future versions. Other cameras might work better for night but mine does go off if senses motion.

In this sensor's normal operation, it stays triggered to ON for four minutes before resetting to OFF. If motion is repeatedly detected within 4 minutes, it stays ON. There are three sensitivity settings, at the most sensitive, it will pick up some rather slight movements. If you can set your program to monitor the status of the sensor to turn the light off after the sensor returns to off, that should work. If 4 minutes isn't enough delay, there is also a "Test" mode in this sensor that eliminates the 4 minute reset time and it will continue sending out ON signals every time motion is sensed. You could program in your own time delay in this mode. No clue on how it would affect the battery life.

It has a light sensor in it. When it is daylight it does not come on. At night the motion sensor is great. The light is very bright, I use it in the entry of my garage to light the way. I would highly recommend it if a bright light is what you are looking for.

A. No, light sensor leaves light off during day even when motion detected.B. If light switch is off, lights are off and sensor has no control.

It works great in mine - here's a tip though.....for some reason my bulb would turn itself off every few hours when it was dark out, perhaps being triggered by some reflection of its own light. I put some pieces of masking tape over the light sensor to make it less sensitive and that fixed it, now it's on all night long but still off during the day.

If you mean, does it come on at dusk and go off a dawn, no. This is a motion sensor light that only works in the dark. Also note, I have other motion lights (120v and much brighter) on my garage. When they are on, this light won't come on because it too light around my front door.
