    Fits most AA LED flashlights. Great replacement for my Ultra Fire SS C3. At 20 O rings you can't beat the price. These O rings have more uses than just in Flashlights. I would have liked the Phosphorescence or glow time to be longer, but it is reasonable. The O rings could be a fraction thicker,... Read more

    Soft, well made. Diameter 16 mm, universal rings is one of the most common thread diameter on the flashlight. The weak quality of light accumulation. Need a bright light to then see the result. Lit long time and need light to recharge again. These sealing rings are spare parts in case of failure... Read more

    These O-rings do what they are supposed to do (namely, prevent water from getting in at critical junctions). In addition, they glow in the dark, which can be handy at times. Their price is also quite cheap. The actual glow time (phosphorescence) of the O-rings is a little low. After exposure to I... Read more

    Green o-rings. Appear to be of reasonable quality. Lots of uses, 20 should last me a while. I don't know what happened, but my o-rings do not glow at all. I can leave them under a very bright light for a long time and then take them in the dark and there is no glow at all. I bought a Ultrafire C3... Read more

    O-rings were all present and accounted for. None were broken. They are a greenish color. They fit the 19187 Ultrafire A10 that I ordered at the same time Thery don't appear to glow. I've tried LED, tungsten, flourescent and sunlight. Don't have a UV light. The tailcap on the ultrafire is a they I... Read more

    Helps to seal stuff. Made my sku02083 light's twisty mechanism feel just right (the twisty felt loose). I think this was the right size, anyway. Pretty tiny little rings. Just get the right size; they make like a jillion sizes, so measure up. These are fun. Even if you don't care for the around I... Read more

    I used these between the lens and the reflector in my torches and they look so freakin cool after you switch off the torch because they are directly charged by the light produced when the torch is on! Really sexy green after glow! err. don't eat them? Please make informative reviews, reviews 500... Read more

    O-Rings arrived in good condition with the exception of a small tear on one of them. Useful for replacing a worn out o-ring, or adding extra o-rings to improve water resistance. They get pretty bright initially but start to dim quickly thereafter. They are still useful for about 45-75 minutes I a... Read more

    -O-rings that glow! Fun :D -Good price for the number of glow rings provided. -It seem that the o-rings are silicone not rubber. Should work better with more lubricants. -Kinda fun to find things to use these glow rings on. -Rings don't glow very brightly. -Glow doesn't last very long. After they... Read more
