30x Battery Operated LED Party Lights Seasonal Lighting for Balloons Paper Lanterns, Waterproof - Warm White

I used a few of these lights in a Christmas cake I made to resemble a snow globe on top of my cake. I topped my “trees” with one light each and placed a couple in the “snow”. They are small enough to incorporate in your crafts or baking or decorating. Easy to use right out of box- just turn the top. No need to install batteries. They lasted for hours until I turned them off. The colors are so pretty. They alternate soft/warm colors slowly giving a nice ambiance to your project.

These work really well. I used the for a ramp I have for my elderly dog. He has a hard time at night. So I put three on a string and put them at the top and he headed for that. I could think of 100 uses. They lasted 24 hours a day bright for 3 or 4 days. I just looked they are still going albeit very low light. But I'm impressed.

Easy to use, the led light was bright.

The Good: These little lights are perfect for what I want and are the perfect color. I am 3d printing lithograph bulbs for Christmas. I don't know how long the battery lasts yet, but I know LED's tend to have a pretty long lifespan. The Bad: The description says that the diameter is 10mm. I made the mistake of printing my first bulb before they were delivered and made the opening 10mm. Well that measurement is WRONG. The correct diameter I measured with my Calipers is 11.1. For the majority of people that isn't a problem, but now I need to regenerate and reprint the bulb with the correct diameter. I also wasted the filament and 15 hours it took to print that bulb on my A1 mini.

these light bullets work as intended.

These lights are perfect for what I needed them for. They are small and bright. The batteries are replaceable. I used them to light up gel window clings. They worked perfectly. I haven't used them since Easter. Some of them have randomly turned on. That is the only issue that I have is when I turn them off a few will come on automatically and stay on. I would turn them off then later in the day a few of them would be back on. It would be both the same ones on or different ones on. The fact that they do this causes the batteries to die down and it makes the light dimmer. I don't want to keep turning them because it will eventually separate into two pieces and reveal the batteries.

I bought these to illuminate book nooks my students made for our school library. They’re small, inexpensive, self-contained, and worked very well for our purposes.

Update. Dropped my review from 5 stars to 1. Maybe I should have read the fine print but these little lights don’t last, period. Not even 6 hours after taking those pictures the lights were so dim you couldn’t see light coming through the windows. Sooo disappointed. Purchased these for my large Christmas Village Houses to replace the electrical chords. Wish they were a little brighter but I ended up throwing 2 in the bigger houses like the train station and chapel.
