In case Mark doesn't see this posting and answer... I can tell you the last note that he sent me about the paint. First of all, he'd tried a paint from a company that claims that their paint glows for 48 hours... and found that was not the case. NOw, maybe it will, but you would really have to charge it up good, have it in a room that gets zero light in it... and then you would not be able to leave the room. Your eyes would need to stay used to the dark. Any going out into the light would cause you to lose your "Night Eyes" and it would be very hard to see the paint for a long time, once you went back into the room.
Anyway, he'd just tried the other company's paint when mine arrived. I hadn't heard back from him for a few days so I wrote to him to see how my paint was working (he wanted to paint the mural himself).
Here is his rely: "Actually yes I did get them, I painted some stars on the ceiling and they appear a tad brighter, been real busy this week so I didn't have time to see how long they last or play around with figuring out some way to light them that doesn't involve dragging out lights."
So, from that, and then not hearing back from him... I am assuming that it wasn't working out for him the way that he was hoping.
If he sees this post... I'm sure that he will answer with more detail.
As for your ceiling... you do not need a white ceiling for these murals to work. Just know that the darker the ceiling color, the more likely my paint will be to have some show up in the light. Out of, let's say, 5000 stars you might see 50 to 60... and they are usually the constellation stars. And, some of the people I've painted for have said they liked seeing the constellations against the black ceiling. It's a personal thing... and ceiling height has something to do with the number that you will see.
Having black lights in the socket, is definitely the way to go, if you have the room for them. With the flip of a switch you can have them charging and with a special paint that I can use... you would also see a lot of the stars, even during a movie. Just as you can see in this picture...
After the movie is over, if you wanted to see the night sky it probably wouldn't hurt to flip on the black lights for 3 or 4 minutes to boost them back up to their peak levels. Then, you could stay in and sit under them for a few hours and enjoy the night sky.
I have had some people leave the dark theater room and then come back in and not see the stars like they were when they left the room. Again, it's a thing with your eyes and the light. With black lights in the soffits... a quick charge is all that is needed when you come back in, and the lights won't mess with anyone's eyes who might be in the room like white light would... and everyone should see the stars right away.
If you want instant stars at all times, during a movie, after you've been in the bright sun or just on demand... then fiber optics are the way to go. But, just know that you will give up a lot of realism. Fiber Optics are easy to use when you want them on-demand (once the wires are run, holes drilled and clipped and then set in place). There is no doubt about it. But, you do give up realism with fiber.
Not sure that helps... but I would be happy to send you a sample of some stars painted on some dark paper so that you can try it out for yourself in your room. If you will send me a PM... with your address and the color of the paint you are using, I will try to match that as closely as I can. Or, if you can send me a sample of the paint on some sheet rock or piece of wood, I will paint some stars on that and send it back to you.
That may be the best option.
Anyway... let me know if you'd like to have me do that. Or, if you are in the Sacramento area, in Texas, Florida, and possibly Wisconsin... I have tentative trips planned to those places in the near future and can drop something by too.
