Which Colors Glow the Brightest?

Strontium aluminate naturally produces green and aqua hues. If you want to get technical, it’s green formulation has a wavelength of 520 nm and its aqua formulation has a wavelength of 505 nm. Blue has a wavelength of 490 nm. In plain English that means green glows the brightest, turquoise lasts the longest, and blue does well on both but is not quite as bright as green or as long-lasting as turquoise. Other colors can be made with strontium aluminate, as with our purple Lume ring, but glow times and brightness are a bit lower, as you get away from the colors strontium aluminate naturally produces.
