How long will the glow last?

It all depends on how thick the application ends up. Thin paint-like coats only tend to last 6-15 seconds. Thick strings like letters or filling in cavities will last longer. 1-3 minutes. It shrinks alot while drying, too. So multiple applications may be necessary. No better or worse than other glo-crafts.

Not too long, dome last longer. You can use them in bathtub, but didn't try to see them glow in water..they are very cute and kids liked them

The glow lasts a couple of days depending on how many coats you put on. Be sure to put your nails under the light or out on the sun after you apply the polish. It does not glow the color of the polish.

They seem to glow all night so roughly 6-9 hours. I bought them and stuck them up in July and they are still at it.

Yes, they should glow. I've used similar ones before, and all the glow-in-the-dark stuff tends to glow with a blacklight, which is nice, so they'll stay lit as long as you like. :)

You have to charge it with light so the longer you charge it the longer and broghter it will glow

No. It does however glow for many years without ever having to first be "charged" like the phosphorescent. It will however be at least as bright as the phosphorescent after it's lost it's "charge".

I did a test on mine which is about 18 months old. On a full charge, 3 lights illuminated on the side, it lasted 27.5 hours. It was still illuminated but about 1/2 the brightness of a full charge. You can easily get 24 hours of useful light out of this.

These are not designed for continuous lighting, but for intermittent and for a couple hours at a time. If left on continuously, the batteries will last around 25 to 30 hours. These had been considered for a commercial display case but were turned down due to having to change the batteries every 3 days.

It's hard to predict the future, of course, but LEDs are expected to outlast incandescents and fluorescents, so they should last many years, even at 12 hrs per day. Certainly long enough that the technology and prices may be significantly different by then.

The level of the glow will depend on how much light the print gets during the day. Ours gets a fair amount but at night the glow is very subtle.

Probably an hour or two... But it really depends how long the string of LED are... I can't really say for sure... They're not that costly so buy 'em and try 'em to see... If you have a dimmer they will last longer.

I found that putting it out in the sun (after its been printed of course) made the glow significantly brighter. As far as glow time I can say for sure but I would assume it would make it glow longer

You have to play with it for a bit. The more it softens up it will glow and change color.

As long as you don't leave it on for a long time. I have mine under my kitchen cabinets. I use them as accent lights and have had them on for about 4 hours at a time about 10 times and they are still going strong. They create a beautiful effect.

You will eventually need to change the UV bulbs out after they have been exhausted. They normally can last anywhere from 1-2 years.-Salon Supply Store

You just bend them to activate the glow and the light should last about a day (we activated ours at night and they were dead the following morning)
