How long does the glow last? Can the glow be reused?

They lasted all night which was several hours. However, I do not know of any glow stick that you can reuse. There were only a couple that did not work out of the 100

Some were still glowing softly the next night but most were no longer glowing in the morning. I tried to freeze and use them again and it did not work with these.

Once activated the glow stick bracelets glow for about 8 hours. The glow bracelets can only be used one time once activated but the connectors can be used over and over.

The package doesn't have any information on it regarding any kind of expiration date, but some larger glow sticks I have say they have a shelf life of up to 4 years. I can't imagine storing these little ones for more than 2 years.

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.

I haven't tested it (Thankfully) but I think I read in the packaging that it would last up to 48 hours. They are really fine LED lights so I could imagine it would last several hours for sure.

It uses an LED lamp, so it should last upwards of 50,000 hours. You probably won't ever have to replace it; at 4 hours of use every day it will last you over 30 years.

You can use any form of light. let it sit in the light for 15-30 mins and they will glow. The glow will fade over around 30 mins

When I used it it lasted a good month and a half. I recolored then because it was fading a bit and after that it lasted another month and a half. It even stayed purple through my rafting trip when I was in the river literally 6+ hours a day for a week.

As long as it's dark. I've had mine up for months and they still glow every night. They look awesome. I love them in my room.

No.but you don't have to worry about that.the LED will far outlive the projector.at 20k hours, you can use it anywhere from 4 to 10 years.

I know what Glow-On is, and it's a fantastic product! (In theory, I don't own it, but I see the potential.) However, I honestly am not entirely sure if this would 'recharge' it per say. Glow-in-the-dark materials require bright, visible light in order to activate their molecular fluorescence. I can only GUESS that the answer is no, but I could be wrong.

I've seen a notable drop in the effectiveness after a year and a half. Even though the bulb still glows, it wears out, producing less UV. I suspected recommended 1 year swap out is based on the the bulb is guaranteed to be still effective (producing enough UV) for a year... after that it'll drop off and become useless despite even it still light up.

It is reusable. I've probably used mine a hundred or more times. If you use it every day, you'll probably need one every three months. I only use mine a couple times a week and I can see mine lasting at least a year. It's pretty well-made.

Honestly, it lasts quite long. even with the crappy brand batteries the mouse came with it lasted quite a while. and in defense of the LED lights, they are cool as hell, and still do not drain the battery that much faster (depending on the battery you use).

It is reusable, but not indefinitely. I don't use it daily so it'll last much longer. It's worth the $$

The battery is in it. I don't think you could change the battery, so once it's used, the glowing aspect of the toy is over.

The glow doesn't last too too long but it does glow constantly under a black light an yes they glow the color of the polish

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
