Photoluminescent Pigment (Glow-in-the-Dark Powder) – Product Description
Overview
Everyglow Glow-in-the-Dark Powder, also known as photoluminescent pigment, is a high-performance light-storing material that absorbs energy from natural or artificial light and releases it as a visible glow in darkness.
Unlike traditional zinc sulfide materials, modern strontium aluminate glow powder delivers superior brightness, longer afterglow, and extended lifespan, making it ideal for safety, industrial, and decorative applications.
How It Works (Photoluminescent Technology)
Everyglow Photoluminescent powder functions like a “light battery”:
- Charging: Absorbs energy from sunlight, UV light, LED, or fluorescent light
- Energy Storage: Stores absorbed light energy within its structure
- Discharge: Slowly releases energy as visible glow in darkness
👉 UV light provides the fastest and strongest charging performance
Key Features
- Long Afterglow: 10–12 hours visibility after full charge
- High Brightness: Up to 30× brighter than zinc sulfide pigments
- Infinite Recharge Cycles: Can be reused for 20+ years
- Non-toxic & Eco-friendly: No radioactive materials
- Energy-saving: No electricity required
- Invisible in Daylight: Off-white appearance, glows only in dark
