I purchased these balloons in a pack of 5 to entertain my daughter last halloween. The balloons look almost the same as normal balloons except they have a small LED light attached inside them and a cardboard pull tab at the open end to activate.

We were very happy with the balloons which glowed quite brightly in a darkened room. They are clearly meant to be used in a party atmosphere and we didn't really expect them to be massively bright because only a small LED is used in them compared to the size of the inflated balloon.

Were we pleased with them?
Absolutely, they all lit up and all stayed lit for at least 48hrs albeit slightly faded.

Will we buy them again?
Definitely, they are not cheap £3.50ish for 5 but I would get them for a party or xmas etc.

At the end of the day they are very good glowing blow up balloons but if you expect anything more showy then perhaps helium is the way to go.
