will this bulb still come on during the daytime or will it sense daylight and stay off??

I installed one on my back porch and it doesn't have a daylight sensor. It comes on day or night if it detects motion. Works good though.

This bulb does recognize daylight. I currently have this bulb on my front porch and its works marvelously.

It is not supposed to light up during the day. We had that same issues a few days, but most days the bulb did turn off. Our main problem is that it would turn on for no reason some nights...and then never turn off. But if there is one thing I am certain of....it shouldn't light during the day.

There is both a sensitivity switch and a switch which has a test position and various number of minutes you want it to stay on. In the test position it will come on even during day light. If you leave it in this position, the motion sensor will allow the bulb to turn on even during daylight. This will burn out the bulb fairly quickly. The longer time duration you choose will also result in shorter bulb life. I installed two of these over a year ago, set to 1 minute per activation, and have not had to replace the bulbs yet.

I placed the light bulb in the socket during the day. I then turned the light switch on. The light came on, so I shut the switch back off then back on. The light blinked a couple of times, then went out. I then left the light switch on permanently and the light has been turning on at dusk and shutting off at dawn. On a really dark stormy day, it might also come on while the dark persists.

It's not a dimmer, so it's really not an issue. I've been using mine with the same CFL bulb in it for almost two years without an issue. The bulb is on at sunset and off and sunrise every day.

Susanna, all the answers below are addressing you testing the light during the daytime. If so, they are correct. One item that you may want to consider is how you have the light powered. This is a powerful light, and at night time I can stand 300' away from my house and see it clearly. So, if possible make sure you are using the correct power source that came with the light, and also, if you have it in a power strip it does not always receive the power it needs. Try plugging it in to a single outlet, and you will probably solve the problemm. Good luck. Dan

No, I don't recall writing that. If I did, I must have been suffering from the sun myself. The light does not come on during the day. It comes on about 30 minutes after sundown on a low setting. If motion is detected it comes on nice and bright for about 30 seconds and then goes back to the dim setting. It stays active the entire night.

I notice it does trigger and go on in the daytime also, but it doesn't stay on for long so I don't know if it would really effect the battery life that much. I love the light! it's bright and lights up my steps better than others I have tried.

Seems like it will last all night if you have it in full sunlight during the day. Mine gets less than 6 hours during the day and is still on, though it be dim at 4am.

I keep it on in the mornings while at work. If it is dark outside, I immediately turn it on. You only need 30 min per day. I keep it about 3 feet away from me in the corner of my eye. It doesn't interfere with my vision at all. The bulbs are fluorescent, and I'm on my second season now with it. It really and truly does work, will give you more energy waking up and knock the blues away through the day. Warning! Don't use it at night as it may keep you awake.

No, this is a motion sensing light meaning it turns on whenever it senses motion. It does not have any sensor related to if it is night or not. If you put it in a fixture that control whether it turned on if it was night or not it would likely work but the bulb itself is only motion sensor meaning it turns on with motion and turns off after around 60 seconds without motion.

It won't come on in daytime unless you cast a shadow over it. I am very satisfied with mine. No luck with battery units, so this is great- a bit of electric, but works as stated.

Remember this is dusk to dawn light.. the light will not trigger ON during the day but Its on nite time if the sensor is triggered.. Hook it up to ON and OFF switch, turn on the switch and leave it ON..

I am also not sure what you mean by "daylight" bulb. If you are planning to use it as a grow bulb, I do not think it will function well in that purpose. This bulb does throw out a nice white (as compared to yellow) light, and it does make reading fairly easy.

It's a motion detector light, so I don't see why it should stay on for 2 hours. Mine is set for 10 minutes, or so. I've had mine for a year or two, and haven't yet replaced the bulb.

Not sure. I know that at twilight it wasn't turning on so I turned up the sensitivity and it turned on. I think if maid it more sensitive to light but I doubt it would work midday.

Yes, it will work fine. I have mine in an outdoor fixture that turns off and on with a dusk to dawn switch (just like a timer) and it works great.
