Glow Sticks Bulk Party Favors - 6" Glow in The Dark Party Supplies Glow Stick Necklaces for Neon Party, Light Sticks for Kids and Adults (25pk Green)

Although the glow on this product technically lasts for 12 hours, it’s not as great as it advertises. In fact, half the intensity is gone within an hour.If you want specifics:Start - 100% brightness1 minute - 80% brightness1 hour - 50% brightnessThen a slow fade from 50% to 0% until hour 12It’s still a good product, but not as good as advertised. Best use is for children, kids parties. For anything professional such as use in clubs or for safety such as blackouts and emergencies, you can find better elsewhere.

Seen like pretty good glow sticks, the kids sure like them. They last all night and then some the next day.

I compared these glow sticks to two other brands. These shone brighter and lasted longer. These sticks were still glowing 48 hours later. Granted, they gradually faded, but they lasted longer and were brighter than any other glow stick I've used. I was very impressed with this product.

Eh. There are higher quality ones out there. They last almost an evening where others last over 30 hours.

These sticks do the job, average brightness. I cracked 4 on Halloween night, threw them in an ice chest with drinks, they were still glowing fairly well 12 hrs later.

Used for May the 4th for a class! They were a huge hit!

Long-lasting, very bright glow sticks that were perfect to add to my son's birthday party goody bags.

Given as party favors for my sons birthday party.
