No it doesn't glow during the day....and you can barely see it during the night.

Sorry, I gave them to my grandchildren for Christmas and I've never seen them glow at night, much less during the day.

At night it will be. Can't see the glow effect in the day time. It's a nice little board tho.

Not dark at all. During the day you can see right through it. At night you can see your reflection, this not allowing you to see directly outside. Hope this helps

Mine does not glow. It is hung up on my toolbox in lighted area. Didn't even know it was suppose to.

You have to "charge" the area with light and then it will glow, it's not radioactive lol

If you left in the sun for an entire day and it still doesn't turn on at night, then it's defective. At night it will produce a low light and when motion is detected it will brighten significantly.

No it don't but it will not come on during the day and only when something is moving in front of it at night

I believe this manufacturer has an option to include an electric light within the tube. Mine puts out quite a bit of light into an otherwise windowless bathroom, but at night it emits a mild glow only when the moon is full. You would definitely need an electric light for benefit after sundown.

It's pretty bright during the day. Other's have said that this outshines most of the other lights. I don't know what lumens it produces, though

Sorry,but,I have never tried to ascertain if it actually glows in the dark or not...Or may be like the so called solar watch`s,at least those in the 1990`s...may be it got fried by the sun...may be the company`s web site might help.

Definitely at night. Day time would depend on the amount of ambient natural light. If its dark and cloudy and the "flash" goes off it may reflect... but if there is enough natural light I doubt it would work. It really won't matter though if you get T-boned or worse yet injure someone else.

It does not glow during daylight, instead it looks like white dot with a black border. It is much easier to see during the day for me than the factory bead sight, due to the much larger size and better contrast of the white and Black. As the other reviews say the threaded portion will need to be filled down so it doesn't stick down into the barrel and I recommend using good locktight and a appropriately sized wrench for installation.

Yes. During the day I use it only under my eyes; at night, all the way around.

Sorry for the late response. The on button glows, which is a little star. It wouldn't really be enough light to see it in the dark though.

During the day you can see out (not perfectly!) but someone outside cannot see you inside. At night, if you have lights on inside someone outside could see you (not perfectly).

It is bright enough to be seen during the day, especially if you have it on a flashing mode. It is very visible as night comes on.
