Mudder 40 Pieces LED Balloon Lights Mini Battery Powered LED Party Lights Bulbs for Paper Lantern Balloon Wedding Halloween Christmas Party Decoration Centerpieces

I bought these to take to a festival and gift out. They work great and everyone loved them. I put them in the porta potties at night and gifted them out to people without headlamps. They're prefect to put on a keychain or a string/necklace. Initially they're SUPER bright for their size. The brightness does fade, but I could use one an entire night. I love that you can easily replace the batteries, so they're not just single use garbage and the perfect size to easily fit in a pocket without taking up too much space. I can't recommend these more. I have one in all of my bags, on my keychain, in my car, and around the house for emergencies.

I made a Diaper Quad-Runner for my Son and Daughter-in-Law’s baby shower. I’ve seen a bunch of them before and this being my first attempt, I wanted to make it as wonderfully unique as possible. I added a “headlight” and used one of these balloon lights to make it more realistic. I got so many compliments on the Quad Runner, and everyone raved about the working headlight! It was a hit! The balloon light was just the perfect size and brightness. It was so easy to use! It also stayed on for the entire baby shower!

We do glow in the dark halloween egg hunts. These were perfect. Last couple years I used different things that weren't as bright. These are amazing

Pretty neat things -- really doesn't work in my application (glass bottle "lamps") but I'll use them somewhere

But after only a couple hours use, already very dim. I doubt they will last the night. It great that the batteries could be replaced but I’ve still got to compare the cost of buying new batteries (3per light) to just buying new lights. Disappointing.
