COREglow, (250g) Small Blue Glowing Pebbles, expose to light and watch them glow blue [approx 75 pebbles]

描述

This Pebble averages 20mmx15mmx10mm Our COREglowTM stone is an engineered glowing stone, based on proprietary luminescent material and synthetic resins (PS, PP, etc). When exposed to a light source the luminescent material within the COREglowTM Stone becomes chemically excited and will maintain an afterglow, initially very radiant, then slowly dissipating. COREglowTM Stone is best viewed in a dark area, where ambient light sources are absent. The luminescent material in our COREglowTM is TMa multi-activated highly efficient powder cultivated from the earth combined with an activating agent, light-storing with a long afterglow, environmentally friendly and extremely Bright - The brightness and duration of the luminescent material we use is more than 10 times that of traditional ZnS luminous material and has a fantastic water resistance compared to the common ordinary aluminate luminescent material. Highly Efficient - With only 10-30 minutes of exposure to daylight or lamplight, COREglowTM maintains its glow in the dark qualities. Best results are achieved in tanks with a light or on a window sill in direct sunlight. Eco-Friendly - COREglowTM Stone is non-radioactive, non-toxic and completely harmless to aquatic life.
