Home Theater Bias Lighting Calculator
A proper bias lighting tool — D65 calibration, display-type intelligence, TV geometry visualisation, and brightness ratio guidance. Not just an LED strip estimator.
What are you setting this up for?
REFERENCE
Reference / Film
D65 — 6500K
Colour-accurate bias lighting matching broadcast standard. For critical viewing, colour grading, and film enthusiasts.
CINEMA
Cinema Warm
3000–3500K
Warmer than reference, easier on the eyes for long sessions. Some colour accuracy trade-off. Popular for home cinemas.
GAMING
Gaming / RGB
Dynamic / RGB
Reactive, colourful, immersive. Not colour-accurate — designed for atmosphere rather than reference viewing.
IMMERSIVE
Immersive / Dynamic
Adaptive / scene-matched
Screen-reactive ambient extension. Expands perceived picture beyond the frame. Ambilight-style experience.
Why D65 matters for reference viewing
D65 (6500K) is the international standard white point for broadcast television, cinema, and digital content production. Your display is calibrated to D65. Bias lighting at any other colour temperature introduces a competing light source that shifts how your eye adapts — making whites look blue-tinted, yellowing highlights, or reducing perceived contrast. RGB rainbow strips are particularly bad for reference viewing: they emit uneven spectral energy that contaminates colour adaptation. For film and colour-accurate work, neutral 6500K is the only correct choice.

Mounting & installation guidance

Design guidance only. Bias lighting recommendations are based on standard practice and your inputs. Display calibration, perceived brightness, and colour accuracy depend on your specific screen settings. For professional colour-critical work, use a hardware colorimeter to calibrate display and bias lighting together.
