Bias lighting is the soft illumination placed behind a display, rather than in front of it. Its purpose isn’t decoration — it’s precision. By raising the ambient light level around the screen, bias lighting:

• Reduces eye strain in dark viewing environments.
• Improves perceived contrast and black levels, so you see shadow detail without crushing blacks.
• Stabilizes color perception by giving your eyes a consistent reference white.

For professionals in post-production, calibration, or photography, it’s a standard requirement. For home theater users, it’s an inexpensive way to make any display look better and more comfortable to watch.

True bias lighting isn’t just any strip of LEDs stuck behind a TV. To meet industry standards, it must follow a few strict rules:

1. Correlated Color Temperature (CCT): The light must be 6500 K (D65), the same white point used for mastering video content.
2. Spectral Accuracy: The spectral power distribution (SPD) must match D65, not just “look white.”
3. High Color Rendering Index (CRI): A CRI of 95 or higher ensures neutral whites and accurate grays.
4. Even Distribution: Light should be smooth and uniform across the wall behind the display.
5. Flicker-Free Dimming: Pulse-width modulation (PWM) flicker can cause eye fatigue, even if you can’t see it.
6. Stable Brightness: Proper bias lighting should be set to roughly 10% of the peak brightness of the display.

Anything that doesn’t meet those benchmarks isn’t true bias lighting — it’s just backlighting.

Most LED strips marketed for “TV backlighting” are bright, colorful, and cheap — but scientifically wrong. They use commodity white LEDs that deviate wildly from D65, shift green or magenta over time, and often flicker when dimmed.

MediaLight was designed from the start to fix all of that.

Engineered to Match D65: Every MediaLight system uses custom phosphor LEDs developed to simulate the D65 reference standard used by professional colorists. Our LEDs have a CRI ≥ 98 Ra and CCT of 6500 K ± 50 K — accuracy that’s typically 40× more costly than the parts used in consumer light strips.

Flicker-Free Comfort: All MediaLight Mk2 systems include a flicker-free dimmer as standard, eliminating PWM flicker that can cause eyestrain or interfere with camera sensors during production.

True 6500 K Across All Models: Whether you choose the professional-grade MediaLight Mk2 or the more affordable LX1, every unit is calibrated to the same reference white. That means you can use LX1 behind a client monitor and Mk2 in a grading suite — and they’ll look consistent.

Proven Reliability and Support: Every unit is assembled, tested, and warranted by Scenic Labs, with industry-leading coverage and direct support from the same people who create the Spears & Munsil UHD Benchmark discs used by calibrators worldwide.

Trusted by Professionals: From mastering studios to broadcast facilities, MediaLight has become the de facto standard for D65 bias lighting. Yet it’s just as beneficial for anyone who wants their home display to look as good as it can.

Bias lighting isn’t an accessory — it’s a fundamental part of accurate image viewing. Without it, your eyes constantly adapt to changing screen brightness, leading to fatigue and distorted color perception. With it, you see what the creator intended.

And because MediaLight adheres to every professional requirement — spectral accuracy, CRI, flicker-free dimming, even illumination, and robust warranty — you get reference-grade performance for a fraction of what a studio lighting system costs.

If you care about seeing your display the way it was mastered, MediaLight is the straightforward answer. It’s not mood lighting. It’s precision lighting — designed for color accuracy, comfort, and longevity.

Illuminate. Captivate. Enjoy.
