20 LED Light Up Balloons Mixed Colors Flashing Lasts 24 Hours Glow in the dark for Birthday Glow Party Favors Supplies Wedding Halloween Christmas Decorations

They are to light and stay lit for the full twenty four hours .. only downside you dont want to let them go the look sooo good

I would have loved for them to stay lit a few more days , heres a suggesting how about putting two lights in and two pulls and you can pull the tabs for the lights as needed .

Colors are great, blow up easily using inexpensive store-bought balloon inflator. LED easily lasted 24+ hrs in the majority of balloons. Highly recommend, would definitely buy again.

These balloons only stayed inflated for a few hours, it was pretty disappointing because they didn’t even stayed inflated for the whole party for my son.

I wish I used helium instead of my breath! It was alot of work!

These were so great for my daughter glow party! We’re better than expected in glowing and lasted more than a day! Kids played with them for awhile. Great accent to add more glowing to the mix

Was so excited for these for an outdoor masked birthday gathering. Paid $1.29/balloon for helium fill and within a couple of hours they wouldn’t float, so either the balloons are leaking or more likely the LED light is too heavy. Also, you need 100% blackout darkness for full effect. Due to a streetlight we did get light blinking which was definitely cooler than unlit balloons, but if we took inside to a totally dark room they would really light up like a strobe light, so just be super aware of tour planned use.

These were great and we received many compliments on them.

Some of these lights inside the balloons lasted for WEEKS!! Will buy again and again!! My autistic son LOVED THESE for his birthday and everyone else did too!!

My kids love these balloons but they didn’t stay lit very long, only 4-6 hours. Def not all night or 24-48 hours like other reviews said. We did buy our balloons 3 months before using them so maybe we had them too long initially. We also didn’t use helium. Some reviews say they aren’t as bright. We found that if you blew them up to max capacity they aren’t as bright so don’t blow them up quite as big. They’re bright if you blow them up to a nice round balloon size. Definitely ordering again and using right away to see if that makes a difference in longevity of light. I will update
