Luminescent and Reflective heat transfer vinyl (HTV) are specialty vinyls that create designs visible in the dark or in low-light conditions. While both offer a striking visual effect, they function in fundamentally different ways. 

Luminescent HTV - Also known as glow-in-the-dark HTV, this type of vinyl has the remarkable ability to store light and then emit it as a soft, luminous glow in the dark. 

Reflective HTV - This type of vinyl does not create its own light but becomes highly visible by reflecting any light that shines on it.
