CALI Strong King Rasta Black T-shirt Glow in the Dark

Glow-in-the-dark T-shirts achieve their unique effect through photoluminescent pigments in the ink. These special pigments absorb and store light energy, slowly releasing it as a visible glow. Here's a simple breakdown:

• Light Absorption: The pigments contain phosphors, which are molecules that absorb light energy.
• Energy Storage: When exposed to light (especially sunlight or UV light), the phosphors become energized.
• Glow Emission: As the stored energy is released, it's emitted as visible light, causing the T-shirt to glow. This glow can last for hours after the light source is removed.

Glow time depends on the quality and amount of glow pigment, light penetration through the ink, and the T-shirt's exposure to light. Because CALI Strong uses the most advanced and expensive photoluminescent pigments, you can expect:

• Brightest Glow: Up to 2.5 hours
• Visible Glow: Up to 9 hours
• Faint Glow (in complete darkness): Up to 20 hours or more

At the dawn of creation, the nine lost gods of the universe gave their very souls to draw forth into our bleak reality the greatest glow shirt of all time and space. This may or may not be that shirt.

Yes! Think of it like a battery. To get the best glow, "charge" your T-shirt by exposing it to bright light. Sunlight or strong artificial light works best. The longer and stronger the light exposure, the brighter and longer the glow will be.

• Sunlight: Lay your T-shirt in direct sunlight for 15-30 minutes.
• Artificial Light: Place it under a bright lamp or a UV black light. UV light is especially effective for quick charging.

Absolutely! To keep your T-shirt looking its best, follow these care instructions:

• Turn it inside out: This protects the design.
• Cold water: Use a gentle cycle with cold water.
• Mild detergent: Avoid bleach or harsh chemicals.
• No ironing on the design: Ironing directly on the glow-in-the-dark areas can damage the pigments.

With repeated washing and wear, the glow may gradually become less intense. Proper care, as outlined above, will help prolong the life of the glow-in-the-dark effect.

Yes, glow-in-the-dark T-shirts will glow brightly under UV (black) light. Black lights are also a great way to "charge" the pigments for a more intense glow.

We're not saying we've achieved zero electrical resistance for our glow apparel from being so cool... but we're also not not saying that.

• Glow-in-the-Dark: These absorb and store light energy, then emit it later as visible light.
• Fluorescent: These don't glow in the dark on their own. They appear extra bright under black light and normal light because they convert invisible high-energy UV light to visible low-energy light. This makes them seem to glow.

• Maximum Charge: Expose your T-shirt to direct sunlight or a strong UV light source for at least 30 minutes.
• Dark Environment: The darker the surroundings, the brighter the glow will appear.
