Ni Glo 2” UV Rechargeable Glowing Keychain – Multi-Purpose Glow-in-the-Dark Accessory for Camping

These are really cool little tubes and are more durable than I expected. I have one on my motorcycle key, which inserts on top of the headlight assembly, so this little guy spends hours every day bouncing around in the wind and rebounding off the chrome, and hasn't even gotten it's first scratch. The included keychain is good quality, too. When in bright sun, like my bike key usually is, it will charge quickly and shine very brightly if taken into a dark space, but the brightness fades to a dull glow rather quickly. It also takes a bit to change using a bright flashlight, though a UV light does the job faster, but again, it fades to a dull glow within a half hour. Basically, if it's daytime and you drop your keys in the shade or into a dark place like a sewer grate, you'll probably find them very easily. If you lose them in the dark, it will could help you find them using a bright flashlight, but only if you sweep slowly enough to allow the material inside the vial to charge as the beam passes. Just don't expect it to still be glowing through the night, even if it was in direct sunlight all day long. It's much more cost effective than a tritium vial, but not quite as convenient. Then again, with these you don't need to worry about carrying a radioactive isotope in your pocket, either. The included photos are comparing this item to two other glow in the dark keychain I own. The Ni-Glo is clearly the brightest, by far. It also retains its luminesce much longer, but it's still only for an hour or two. The pics were all taken at the same time using different shutter settings because I couldn't decide which best illustrates the difference between the three. They had all just made the morning journey home from work in my pickup and had the same amount of light exposure.

Compact, durable glow sticks that charge traditionally by being placed in sunlight. These things are perfect for my needs (ie: marking potential tripping hazards around my campsite at night and attached to headlamps/ lanterns to be located in the dark. They are not super bright and not supposed to be. They are visible for hours in the dark with a full charge though which make them perfect for locating or identifying items at night.

They are ok they glow very dim when in darkness. Bright at first then they dim down.

Set these in the direct sunlight for an hour and they will glow all night. Perfect for tents, hammocks, backpacks, etc. Also, the glow part is a powder! If you needed to mcguyver a message with something sticky that would not be readily visible, this would allow that. Just break oben the bottom of the vial. Maybe dust some on the ground as a secret marker, endless possibilities!

Something fun and different. I bought these for my keys and gear when I'm off camping or at work. I like that they react well to sunlight and have a good glow through the night. They seem to be made of a good quality plastic. Small in size to not clutter or get in the way.

Shine a light on it for a while snd it glows nice. An hour or less later it is pretty nuch dead. So luggage on a flight isn't really going to be effective. Says to shine for 10 minutes. I do not think that will help. I shined it for maybe 2 mintes with some bright lights. It glows real nice at first then quickly fades in 5 minutes. 30 minutes it is almost dead. If an hour goes by it is almost completely out. I think a solar light with a battery would be and work better or dog collar watch battery thing might be a better idea for a green glow. Nicely made and works at first but doesn't last like you hope it would. Glow sticks you break with a chemical in them would work better but that is a long term one time deal but is quite affordable. Maybe not TSA compliant. This doesn't work to find your luggage like you hope it would.

I added one to my 4 wheeler keys and hunting backpack. Don't plan to loose either in the dark but you never know. These soak up the sun very well and stay lit for a good amount of time after. But you really need to be outside for a while for these to be effective into the evening, otherwise they are very dim.

At about an inch and a half long this solar-charging mediocre glow stick (that is about the intensity of a day old glow stick that wasn't stored in the freezer) isn't doing much to help anyone find anything, that isn't already in front of them, at night. Yes, it is easy to clip onto a carabiner, or keychain, but the lack of illumination makes it a barely functional waste of money no matter how simple attaching it is.

Cumple su función a la perfección, buenos materiales, colores muy vivos y muy bonitos…

Very useful to clip on for keys.

Even after a while under just the lights in my room, never mind daylight, when I put the lights out they are very clearly glowing before my eyes adjust to the dark. I'm not sure about how long it lasts but certainly a few hours later middle of the night they were still glowing clearly, better than I'd expected.

ちゃんと光を当てればかなり明るく光るので、大事な鍵には必須のキーホルダーです

Sind nicht sehr groß aber passen schön an ein Schlüsselbund. Die Leuchtkraft ist direkt bei Sonnenlicht da und hält auch etwas an. Gut beleucht geht es die Nacht durch, wenn auch nicht sehr hell, aber ein feiner Schimmer sorgt für Orientierung. Gefällt und daher Kaufempfehlung.
