Understanding VLT: What Window Tint Percentages Actually Mean

If you've shopped for window tint before, you've probably seen it described by a percentage — 35%, 20%, 5%. That number is VLT, or Visible Light Transmission: the share of visible light that passes through the glass and film combined. A higher VLT means a lighter, more transparent tint; a lower VLT means a darker one.

Why the range matters

Most tint film locks you into one VLT the moment it's installed. GhostTint doesn't — it adjusts across seven preset levels spanning roughly 5% to 70% VLT, all from the same film and the same included wireless remote. That range covers most of what drivers actually want from tint: near-clear glass for a bright day or a parking garage, a mid-range setting for everyday privacy and glare control, and a deep, near-blackout setting when you want maximum privacy.

Matching VLT to the moment

Different situations call for different VLT levels. Highway driving at night benefits from a lighter setting so you're not losing visibility. Parked in direct sun or on a hot afternoon, a darker setting cuts glare and heat. Because GhostTint switches levels on demand, you're not locked into one tradeoff — you're picking the right one for right now.

One thing to keep in mind: tint laws set limits on how low your VLT can legally go, and those limits vary by location. We cover what to check before you install in our guide on whether adjustable window tint is legal.
