Entire glow in the dark room?

Ignoring the practicalitites of expense, chemicals etc, would it be possible to paint and ENTIRE room, or at least a whole ceiling, in glow-in-the-dark paint? I'm thinking what would it be like to have an off-the-grid room that would have a useable amount of light, using glow-in-the-dark paint, for say 4 hours after sunset. Can anyone find any pictures of a room painted like this?

I found this Instructable searching for information on using glow paint as a replacement for solar garden lights. If the pricey, high-quality glow paint can light up a room for hours after being exposed to light, I imagine that it might work well for what I'm imagining, but does anyone have any experience with this? I envision rocks painted with glow paint that illuminate my garden paths and eliminate the need for low-voltage/solar lights altogether.

First, let me disclose that I am a Senior Technician at Glow Inc., which manufactures glow in the dark paint.

The majority of glow paint sold in retail stores is 1/30th the brightness of high-end glow paint. Not only are the higher end pigments 20+ times brighter, commercial products are usually made with a 20% ratio compared to retail product at about 1% ratio.

A quart jar of V10 grade glow paint sitting next to my bed was bright enough to read by after the first hour. It was bright enough to navigate the room after 5 hours. If you painted all 4 walls and ceiling, I am quite certain you could read by it all night.

With how much charging? If you read the old posts, it sounds like the idea is to illuminate the room at night given no more than "typical" (indirect sunlight through windows?) illumination during the day. I doubt that even really good GITD paint is up to it. (The advantage of solar panels is that you can put them in the sun and the powered light-source where you need the light.)

A problem with solar-powered light sources in general (both GITD and solar-electric) is that they tend to waste a lot of their energy when it isn't really needed. My solar garden lights go on at dusk, and "waste" an hour or two wort h of their scarce energy lighting up their LED before it's really dark enough to need it. Sometime I'm going enter one of those "low power microcontroller design contests" with nothing more than a solar-powered solution that has a better "dark detector."
I still stand by my original statement that I am certain a room painted with V10 level glow paints would provide at least 4 hours of enough glow that you could read. This includes the fact that there is no other lighting or power and the only charging source is the windows. In fact, I think it would be down right annoying to sleep in the room.

Interesting. So in rough figures how much would I be looking at to paint a 3m x 3m ceiling?
Two quarts ($334) for the ceiling. But it gets the least amount of charging light. The walls would be a critical component. You would need 2.5 gallons ($1250)for the whole room. I am providing costs for reference only. I am not posting this to be a sale or spam. My intention was to simply point out that high-end glow in the dark is an option. Danny Clark Glow Inc.

Totally understand that, thanks. Well it seems like it could be an interesting and totally unique option. Although I'm guessing international shipping might be a problem?
We can ship raw glow pigment, but not the paint internationally. Thanks, Danny Clark
Here's one from the vault.

It sure is possible.... In fact - a few years ago - a friend did that to his dorm room... With washable glow in the dark paint :) As for would it work for your use.... probably not as phosphorescence doesn't give off that much light in this application :/
