Do not be mistaken, this is no glow-in-the-dark stick-on stars affair. We use specially designed and manufactured paint that, once charged, will glow for up to 12 hours. Any normal lightbulb can be used to charge your Nightsky3D ceiling. As daylight fades your Nightsky3D ceiling starts to glow (with lights out) and as dawn approaches your Nightsky3D ceiling stars will fade - just like the real thing! No need to worry about the weather when star gazing with your Nightsky3D ceiling. Glow-in-the-dark stick-on stars are nothing compared to a Nightsky3D ceiling!
