How to plan our wedding and as we run sky lanterns are prohibited, we came to them up to the idea of LED balloon in the air. To test we bought a pack to the balloon test. We bought it in white. The balloons light up really nice, of course, it must be in accordance with this dark.
The test balloon we have inflated Sunday evening and on Thursday could still recognize a subtle glow in the dark. We are still definitely buy a few packs and leave to rise for the wedding.
