VLT, or Visible Light Transmission, is a measurement of the amount of visible light that can pass through your window tint. It’s typically expressed as a percentage. A higher VLT percentage indicates that more light can pass through, resulting in lighter window tint. Conversely, a lower VLT percentage means less light can pass through, resulting in darker tint. Understanding VLT is important as it determines the level of privacy, glare reduction, and heat rejection provided by your window tint. It’s essential to be aware of the legal VLT limits in your area to ensure compliance with local regulations when choosing your window tint shade.
