LightLead photoluminescent pigment is based on strontium aluminates-silicates, excited by rare earth, free from any radioactive substance and toxicity and with strong capability of absorbing-storing-emitting light, the pigment can glow in the dark automatically for several hours after absorbing varieties of visible lights for 5-10 minutes. 

Lightleader can also provide the traditional zinc sulfide base pigment excited by copper, the difference is that the excitation and emission time of this pigment is much shorter.

Lightleader can offer UV Excitable Pigments. These pigments have a yellowish or white color body under visible light and produce a bright vibrant color when exposed to a Ultra-Violet light source.
