How does it glow? Is it after leaving it in the sunlight?

Yes it's light charged, but really it's not a super bright glow. Don't buy this for the glow effect you will be disappointed, but do buy this for the style and look of the case as it is very nice.

Might not be a bad idea, but not required. Try to avoid pointing the light right in your eyes when checking to 'see if it's on'. Instead, point it at a white piece of paper, or white t-shirt. Even in daylight and on 'low', it'll really glow.

The spray goes on as a pale white/green layer, very neutral. It will glow in the dark for a short time like all glow in the dark paints. To test, "charge it" with a flashlight!

It's more of a glow than usable light. I use it as an accent for my walkway. Not sure of the wattage.

In short, yes. It needs to be exposed to light for only a few short seconds to make it glow. I've had this guage for a year and absolutely love it. Much better than the other guages in the market. Would not hesitate to buy again if needed.

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

I bought it last year and it's still glowing. But I don't know how many minutes are glowing. It's depends on the stars get a light, and it's like more than 30 minutes glowing. Sometimes more than an hour. I'm satisfied with that.

It should glow right away. Check to make sure your plug is 'live'. Otherwise, you got a defective unit.

Starting at dark, we noticed a low glow until we went to bed so how long after that I don't know. I know at least two hours then after that, don't know! :)You won't be covering much with one package of this. So far we have gotten two & will be adding to it as we can.

After being in sunlight for a long time, it will glow for 30 minutes or so. But can hold it up to light for 30 seconds and it will glow long enough for a fetch or two...

You are right. It does not glow no matter how much is sprayed on. I will never buy it again.

YES!! I held it in the sun for 20 seconds and walked into a dark closet. BINGO. The numbers and the hand DO glow. If you are trying not to wake a patient, just hold this in the light before you enter the patient's room. I didn't test how long it will glow but in the right circumstances, this could be very helpful.

Mine does not glow in the dark. But still I recommend it. I have had it for a year now, It is a very nice addition in my backyard. I am very pleased with it. It is very well built, It looks and it spins great. I absolutely recommend it.

Mine look like they glow after they have been also. They eventually go out. I haven't had any trouble so I'm sure it's OK.

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.

It's a black light, like the kind that makes certain colors like white glow brightly, only it's not an incandescent bulb, it's 12 LED's which doesn't give off much heat energy, so batteries last a lot longer. UV-A is a color of wave length that is outside of our visible range. Mine arrived kinda silver/chrome in color.

It is a spray paint that dries clear. In previous posts I stated that any light at all negates the glow effect. Hope this helps.
