4 Pack UVGloStik- Reusable Glow Stick

Small, light weight, can be seen from a great distance.

Since my kids are walking to school in the dark in the mornings, I ordered them to increase their visibility. Just putting the packs in a well lit room before school provides enough glow to give them the extra visibility on the way to school.

Long lasting. Very good for the price. I would not want to read from them, but for diving, you can see them well enough.

These things are great for markers but not great for much else. Very bright after a charge but fun quickly. That said they never go out and when your eyes adjust to darkness it’s more than bright enough to be see.

I cut these in half and get two for one. Then I used them for zipper pulls in my backpack and tent. Helps to find zippers at night.

These are an epoxy bar with some glow in the dark crystals inside.The epoxy is crude, with sharp edges. It's surely durable but could have been smoother.The glowing crystals aren't what they are drummed up to be. I have done Brady tape that shines much longer, this thing shines for less than an hour at usable brightness

I purchased 4 of the sticks and 2 of the packs at a camping fishing show 12 years ago. I accidentally left the packs on a boat I sold. So I don't know about them. Two of the sticks I put in the space between my hot tub stairs so I could see them at night. I had the hot tub for 4 years before I sold it and they were still glowing after being outside in the elements in Missouri. The remaining two sticks are still hanging on my doorknob and they glow every night. They're always ready when I need them. Great product. These glow sticks have outlasted many flashlights and cell phones. They never need batteries and they're always ready.

Is as bright as a chemical lightstick ONLY after charging it close to a bright light source, like 5 cm close. Ambient charging DOES NOT make it bright at all. I think those luminous stars stickers, etc are brighter from ambient charging. Worse is that the charge fades within 1 hour and become quite dim. As a test, I left one stick out at the window during the day receiving sunlight. It wasn't very bright and by midnight, quite dull and just be dawn, there is no luminosity.Can't recommend.You can test for yourself, just don't buy 4 of them.
