I'm looking to add some glow-in-the-darkness to the side fret markers (on the top of the neck).
Anyone use markers or http://www.amazon.com/White-Glow-Pai..._bxgy_ac_img_z?
I'm leaning toward the paint. Figure the dots are sold with some kind or light to get them to glow. Sounds dubious. The paint seems more durable.
The Luminlay dots will charge with any light that has UV in it. Fluorescent lights work great, but so do incandescents, daylight, whatever. The LED lights they sell on the Luminlay site will also do the job nicely, but aren't necessary.
There are two classes of glow material. The older stuff is Zinc Sulphide, which is the stuff most of us grew up with. The glow is weak and doesn't last long. The newer material, Strontium Aluminate is orders of magnitude better. It charges faster, has a brighter initial glow, and the residual glow lasts longer. This is what Luminlay uses. When you buy glow-in-the-dark paint or markers, the seller may not know what chemistry their glow material uses. Buyer beware.
You can also buy Strontium Aluminate glow powder on eBay and mix it with your own resin. But the guys who make Luminlay have already done a ton of R&D to pack the most glow material possible into their little rods, and they work quite well. They also coat the outside of the rods with white to keep more of the light reflecting out the ends of the rod.
