Unlike glow sticks and old school ceiling stars, the new generation strontium aluminate based stars can be recharged charged over and over.

You’ll notice that your glow art and stars are brighter at the beginning of the night than just before dawn.The difference in brightness happens because the light has been discharging all night and just needs to be recharged the next day. (If you can't wait you can blast it with a top up during the night.)
