Glow-in-the-dark paint

Postby VultureChow » Thu Dec 11, 2014 11:01 am

Anyone with any experience using glow in the dark paint for an art project? I initially intended to do a reflective paint, but thought an off white glow in the dark paint might work as well. Bear in mind, this is not the primary method of nighttime safety illumination, rather just something to add to the experience.

So then, you're hoping the primary source of light will provide enough light to set the paint glowing?

Nah, primary light source is perimeter in ground lighting leading up to the piece. The piece itself, is more dimly lit from within. The glow paint would be exposed to enough sunlight to "charge"

My buddy painted his bike with glow-in-the-dark paint. It didn't work out too well, we think it was due to the thin layer of dust that ended up all over it. It was very dim, and only really visible from about a foot away. If you're looking for a very mild effect, it could be exactly what you're looking for, though.

Not sure what brand/kind of paint he used beyond that it was "glow-in-the-dark" and "charged" from light. We would draw on it with a laser. It was pretty fun to do that, at least!

If you want that charge to hold, you're going to be paying for some expensive paint. The manufacturers will say you get "6-8 hours under ideal conditions" or similar wording, but they will also let you know the paint will "dim over time". In my experience that dimming makes it barely visible in about 4 hours (and it starts getting noticeably dimmer within an hour).

I'd recommend going for a black-light paint, and then putting a small UV light in front of the piece, or attached to it. It will glow as long as the light is on, and it will make a much brighter glow.

Yeah I'll second Eric's plan. Fluorescent black-light paint illuminated by some blacklights does work pretty well. Glow-in-the-dark doesn't. I've used a little of each on the playa before.

It really is funny - Eric and I would seem polar opposites in every way, but tend to agree on everything! Opposites attract?

Glow-in-the-dark paint is very very dim after only 15 minutes. The "24-hour" paints are cool but only useful in pitch black.

Roscomake really great UV reactive paints, they're professional quality rather than just craft store stuff.

Oh great, Tatonka. Now you've got me drooling and my brain spinning.

Ugh. I'm going to have to request a quote...

And this is why I come to the brain trust here. Thanks guys. I'll be experimenting with UV paints. Thanks.

I've had some really great experiences with glow in the dark paint... however, you've got to have the right expectations.

First, it will NEVER last anything close to what they say. Second, most people who deal in lighting or glow related products have REALLY TERRIBLE websites lol. Third, trial and error.

The place to look into is called Glow Inc. They're pretty much the best performing provider out there, my guess is that they're the company who makes the powders that wind up getting used in the majority of peoples' paints and treatments. They provide some great info on their site, though from my experience the glow only lasts about half as long as they claim. My guess is that they're measuring glow with light meters, or in completely black enclosed rooms, where something you'd never see on the playa still has what's perceived as a noticeable glow. Using their longest-lasting paint, which should have lasted 24 hours, was dim by midnight and barely visible by the time the sky started lightening.

That wasn't too unexpected. I had picked up one of their little sample kits and made a little test board with the different colors and we experimented with it at home to see if it would suit our needs. That turned out to be really helpful, and saved us from spending money on a glow color we liked but that wouldn't have worked at all for our purposes.

Depending on what you're doing, you may also want to consider UV light. You could either go the direction of fluorescent/UV reactive paints and light to drive it, or use UV light as backup or to 'charge' your glow in the dark stuff. There are some pretty solid LED UV lights out there that can provide a decent amount of UV light without drawing a lot of power.

Here's a pic of my ziggurat at night on the playa... taken some well after midnight, I imagine. The purplish glow is courtesy of a UV LED flood that I have on each side of the installation. As you can see in the pic, the fluorescent-painted bits really pop nicely. If you look closely, you can see two little starburst-looking glyphs (bottom center of the panel). That's the effect of the most glowy glow-paint that charged all day and has that UV flood giving it some support.

Hope that info helps, and good luck with the project!
