The Blue Moon Luminous Lux Board will emmit an eerie bluish color for up to 100 hours after a single charge. The glow comes from Strontium Aluminate with Europium as the activator. This an expensive industrial pigment that I mix with a binder and paint into the relief of the board. Like all of my glow-in-the dark pigments, it is non-toxic and non-radioactive. This board glows very bright but may take a little longer to charge than the green one. Interesting note: I was drying the board in the sun and then brought it into a brightly lit room. It was actually bright enough to see the glow in the light.

There will be more information added at a later date.
