You can also get painted glow in the dark stars on your ceiling by an artist however by it's very nature painted stars will die off very quickly and you will not have the longevity that you will get with a designer product like my XVR glow in the dark stars.
The reason for this is very simple, painting a glow in the dark star as an individual dot or trying to flick glow paint on your ceiling to get multiple glow in the dark stars in one shot will give you stars without any pigment mass.
Why will this matter?
In order for each individual glow in the dark star to perform at a certain glow level and for a given amount of time it needs to have a certain level of glow in the dark pigment loading. The required loading above a certain level of brightness is not achievable by a painting method as there is simply not enough mass for each glow in the dark star to contain the correct pigment.
Think of each glow in the dark star as a body of water, the correct amount of water would be say 9oz yet the painted glow in the dark star can only hold 2oz because it has no physical mass to hold any more.
Having said this more intensity does not = a more realistic product. Take fibre optics this is a great example of too much intensity and no control. Great glow in the dark stars will have a range of intensity from very faint to very bright but fibre optics are on or off and when they are on they are far to bright to produce anything even remotely close to realistic.
My glow in the dark stars are unmatched in realism they are a designer product and the creation of many years of development so if you are after a very relaxing night sky illusion that will give you the look of the truly realistic night sky then my XVR-Glow in the Dark Stars are for you!
