40pcs LED Light Up White Balloons by ALUNME Non Flashing Party Wedding balloon Lights Long Standby Time for Dark Party Supplies,Wedding Decorates

These balloons worked great! I had no "duds". All of the lights worked. They stayed lit-up for several days. You do have to fully inflate the balloons with helium if you want them to float. I floated all of our balloons to our vaulted ceiling for an at-home prom during the pandemic, and the 8 high school grads who were here thought they looked beautiful. Posted June 2020.

I used these in our huge Maple tree as decorations for a 40th birthday party. Everyone loved them. I also used them to light a pathway at our family property. I tied them to trees and it made it look magical. At our family reunion, the kids had so much fun running around with these after dark. They were very excited to have light up balloons to play with. I have also floated them in our hot tub at night. Definitely a lot of fun to use and a great value.

Not at all bright as shown in the Advertising!!! Only bright in the circle of the light source. 10-12 hr max!!!

We got these for a 17th Birthday. We blew up the balloons with helium. They were very easy to inflate. We covered the ceiling with the lighted balloons. It looked amazing and the lights lasted the whole evening! The balloons were thick, but not too thick as to block the light.

Works as described. Just pull the tab and inflate. Only putting three stars on as the glow was very faint when the balloon was fully inflated. Tied them around the arch at a wedding and they barely glowed.. Found that inflating them smaller helped. It was during the day but was cloudy and lights in hall were dimmed. Still kids loved playing with them. Decent price and worked ok.

The light is dim, so to be able to see the balloon it has to be completely dark. It’s difficult to use them in a place with all the lights off. I used them at a party with low lighting, and you couldn’t tell they were turned on.

The lights literally last forever! They are bright the first 6 hours then demand a little after but stay lit for days!

These aren’t as bright as I expected even at night outside. They’re durable and retain air. The kids loved them way more than I did. You can basically clearly see the light in them, so it doesn’t glow like I expected.
