How are they activated and how long will they glow, once activated?

They are activated by snapping(bending) them. It's been awhile, but I seem to remember them glowing for well over an hour. It may have been several hours. I remember by morning they were no longer glowing.

You just bend them and they light up. They last probably about 12 to 16 hours but my kids will put them in the freezer if they still have a lot of time left and when you take them out of the freezer they stay lit up for awhile longer.

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)

Hello, just as pictured and yes they do glow in the dark! My kids love them and are easy to handle. It took about 2-3 weeks to arrive, but worth it.

Once the Timer is set, it stays lighted for 6 hours....... then off for 18 hours. I bought 5 and I love them. I've used them on decorative wreaths on my front door and on house plants to add sparkle.

Hi. Unfortunately they cannot be programmed I have one in my backyard for my dog. It will usually stay on for 30-35 seconds. The sensor is pretty good with movement I also like the brightness of it Takes 4 D batteries. Durcells work well

They are on timers. They go off 4 hours after you turn them on, they are amazing!!!!

They will last all night and probably 2 to 3 nights. They are powered by three 1.5 volt lithium batteries and can get pricey. However, they are nice and soothing. They contiuously change colors

Mine glow all night. The length of time they glow depends on how long you have them in the light. If I leave my bedroom light on for a couple hours, they usually are still glowing by morning. They're not going strong like they were when I went to bed but they are glow in the dark stars that need light to build up their glowing power.

We use them to light up the engine compartment and interior of our show cars. Normally have them lit around 10 hours at a time. After 3 day's they become somewhat dim for what we want but are still lit. Bought a dozen and love them.

Not really sure about the actual "recharge time". The balls glow via something similar to 'day glow paint', so I'm guessing they'll start glow again from 5 to 20 minutes after re exposure to light. But the longer they are exposed, the brighter and longer they will glow--so, an hour or two works best for me.

They glow a pretty long time. We have it hanging in our bedroom and they almost keep me up because they glow so bright, haha. I'd say about 20-30 minutes until they are completely out.

When you first turn them on they come on and stay on for a few minutes. You can set how long you what them to stay on for up to about 15 minutes. If you know wiring you could by pass the sensor so they would stay one as long as you wanted them too with a switch.

I have only tried to use a few to the point of exhaustion, but the ones I had lasted for more than 24 hours. I used three in little votive glasses to be a night light for anxious grandchild, and they were bright and cheerful for two night. I did turn them off during the day, and they burned quite brightly for 2 nights plus. I like these.

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.

They are packed tightly in the box I just used them this weekend for the kids at my sister's wedding reception. In the whole box only 2 didn't glow. I would definitely buy them again.

They light up for a few seconds when they strike something. I'd say like 5-10 seconds

I don't know. We've had them for 3 months now and the glow is still strong. Having them out in the light seems to do it. Only time will tell if they become weaker.

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.
