Dolby recently published a great article on how to set up bias lighting for Dolby Vision content creation, and we were thrilled to see the MediaLight Pro2 featured as an example of a professional-grade solution that meets their criteria.
The guide explains why bias lighting is such an important part of an HDR workflow—helping reduce eye fatigue, maintain accurate color perception, and improve the way we perceive black levels on modern displays. Dolby notes that the right bias light should:
Match the D65 (6500 K) reference white point
Offer smooth, adjustable brightness control
Reflect off a neutral gray wall for accurate color balance
We sent Dolby engineers a few MediaLight Pro2 units for testing a while back, so it’s nice to see them recognized in the official Dolby documentation. That said, it’s not just the Pro2 that meets these standards—our MediaLight Mk2 and LX1 lights also exceed SMPTE, ITU, and CIE recommendations for color accuracy and chromaticity.
So whether you’re mastering Dolby Vision content in a professional suite or just want a reference-quality setup at home, every Scenic Labs bias light delivers the same trusted D65 precision.
