Beaubleu Paris Breaks Down SuperLuminova’s Glow and Its Limits

Beaubleu Paris’s journal describes Super-Luminova as europium-doped strontium aluminate in a binder, applied to hands, markers, or dials to absorb and emit light. The key detail: the glow peaks early, then fades over hours, and an uncharged dial emits nothing.

It details Standard, A, and X1 grades, noting X1 can be 60% brighter than Standard after two hours, per RC Tritec. Beaubleu’s Seconde Française 20.24 Pearl Grey and Salmon use X1 only on the round hands, not markers.
