ColorLEDProfessional ColorLEDProfessional TYANSHINE brings the RGBLAC 6-channel LED architecture to professional film, broadcast, and stage lighting — engineered for uncompromising color fidelity across every wavelength.
Traditional RGBW covers only ~65% of the CIE 1931 gamut. The critical yellow-green region (540-580nm) — where human vision peaks — remains poorly represented, causing visible color inaccuracies in warm white tones.
4-channel mixing produces metameric matches that look acceptable to the eye but fail on digital sensors. ARRI, RED, and Sony Venice cameras expose color mismatches invisible to the naked eye.
RGBLAC extends the controllable gamut by ~1.4x vs RGBW. Lime (565nm) and Amber (595nm) channels fill the critical warm-white gap, while Cyan (498nm) perfects cool-white reproduction.
6 independent channels enable spectral tuning per camera sensor response. Achieve TLCI > 95 and SSI > 90 simultaneously — a feat impossible with 4-channel architectures.
The 6-channel RGBLAC engine spans 400–700 nm with zero spectral gaps. Lime fills the critical green-yellow valley; Amber anchors warm skin tones; Cyan bridges blue-green.
Each channel serves a specific role in the spectral reconstruction chain. Understanding their purpose reveals why 6 channels outperform 4.
Foundation of warm color rendering. Critical anchor for skin tones, reds, and the entire warm-white CCT range from 1800K–3200K.
The gamut extender. Fills the critical yellow-green gap where human vision peaks. Single most impactful addition for CRI and TLCI improvement.
Primary luminance channel. Dominates the luminous flux output at ~70% of perceived brightness. Essential for daylight simulation.
The warm transition bridge. Smoothes the Red-Green boundary for superior 2700K–4000K reproduction. Eliminates pink/magenta cast in skin tones.
Cool-white anchor. Powers CCT ranges above 6500K. With Cyan support, enables precise Ge-Mg shift control for broadcast compliance.
The cool precision tool. Bridges Blue-Green gap for accurate 7000K–20000K reproduction. Essential for daylight-balanced broadcast and HMI emulation.
Extending the spectral boundaries at both ends of the visible spectrum, this 8-channel architecture goes beyond the core RGBLAC engine. Deep Red 660nm anchors the long-wavelength frontier — dramatically boosting R9 saturation, enriching skin-tone fidelity, and delivering the visceral warmth that standard RGB solutions inherently miss. At the opposite extreme, Indigo 405nm unlocks near-UV excitation and fluorescence effects, enabling theatrical UV-reactive staging and specialized horticultural spectra without external UV fixtures. Together, this platform pushes color gamut well beyond Rec. 2020 coverage, delivering true full-spectrum white, hyper-saturated theatrical color, and human-centric circadian tuning — all from a single compact LED array.
1.4× wider gamut than RGBW. Covers DCI-P3 and Rec.2020 with superior metameric control. CRI > 95 across entire 1800K–20000K CCT range — no falloff at extremes.
Factory-calibrated per-LED spectral LUT. 6-channel DMX/RDM with Ge-Mg shift compensation. CAM16 perceptual uniform space for smooth CCT transitions.
Linear Optimization over 6 degrees of freedom. Simultaneously optimizes color accuracy, max brightness, and CRI. Supports spectral tuning per camera sensor (ARRI/RED/Sony).
Netflix-approved cinema lighting. Broadcast-compliant Ge-Mg control. Stage-ready with professional console integration. 500W+ high-power module leadership.
IESNA LM-80-20 compliant. Lumen maintenance > 90% at 60,000 hours. Tested per IES standards.
Full CCT range 1800K–20000K. Ra > 95, R9 > 90. No falloff at warm or cool extremes.
EBU Tech 3355 compliant. Netflix-approved spectral quality. SSI > 90 for cinema sensors.
RGBLAC is a 6-channel LED architecture that adds Lime (555–570nm), Amber (590–600nm), and Cyan (490–505nm) channels to the traditional Red, Green, Blue triplet. This expands the controllable color gamut by ~1.4× and enables CRI > 95 across the full 1800K–20000K CCT range — something impossible with 4-channel RGBW systems.
RGBLAC achieves TLCI > 95 and SSI > 90 — meeting Netflix and EBU broadcast standards. The 6-channel architecture enables spectral tuning per camera sensor (ARRI, RED, Sony Venice), eliminating metameric failures where colors look correct to the eye but wrong on camera.
TYANSHINE provides RGBLAC COB LED modules from 100W to 2500W, covering compact on-camera lights to full-size film studio arrays. All modules maintain CRI > 95 and TLCI > 95 across their respective power ranges.
The main trade-offs are: (1) Higher cost — 6-channel calibration requires per-LED spectral measurement and LUT generation, roughly 2–3× the cost of RGBW; (2) Control complexity — 6 DMX channels require professional consoles with proper color engine support; (3) Optical design — 6 wavelengths require careful mixing to avoid color fringing in projected beams.
The 8-channel extension adds two strategic wavelengths at opposite ends of the visible spectrum, yielding measurable gains across five key dimensions:
1. Expanded CIE Gamut: ~1.7× vs RGBW (up from ~1.4× with 6-channel). Deep Red 660nm pushes the red primary to the spectral locus edge, while Indigo 405nm extends blue-violet saturation beyond what standard Blue 450nm can achieve alone.
2. Extended CCT Range: 1600K–25000K+ (vs 1800K–20000K on 6-channel). The 660nm channel enables accurate sub-1800K candlelight/firelight simulation, and the 405nm channel refines daylight accuracy above 10000K for HMI emulation.
3. Superior R9 & R12 Values: R9 (saturated red) rises from 85–92 to >95 — critical for skin tone fidelity under Netflix/EBU broadcast standards. R12 (saturated blue) jumps from 80–88 to >92, eliminating the common "blue muddiness" of multi-color LED systems.
4. Fluorescence & Special Effects: The 405nm near-UV channel excites fluorescent materials, enabling glow/blacklight FX that are impossible on 6-channel systems. This is increasingly demanded in concert touring, immersive theatre, and EDM festival lighting.
5. Multi-Industry Applications: Deep Red 660nm matches Chlorophyll A absorption — enabling hybrid film/horticulture fixtures. Indigo 405nm is the standard wavelength for forensic inspection and UV curing, expanding use into industrial/commercial markets.
Trade-offs vs 6-channel RGBLAC: (a) 2 additional control channels increase DMX footprint and console complexity; (b) approximately 25–40% higher BOM cost due to additional LED dies, drivers, and 8-channel spectral calibration; (c) the 405nm channel falls within IEC 62471 blue-light hazard classification — fixtures require appropriate optical diffusion and safety labeling; (d) deep red's low photopic efficiency (V(λ) < 0.1 at 660nm) means the channel contributes minimal perceived brightness per watt — it is a color-quality investment, not a lumen boost.
From cinema stages to broadcast studios and touring rigs, TYANSHINE RGBLAC modules are engineered into productions that demand flawless color. Here is what our partners tell us.
The RGBLAC modules finally killed the color fringing we'd fought for years. Our ARRI Alexa footage now matches the on-set monitor with zero LUT work — the spectral tuning per sensor is the real deal.
TYANSHINE' 2500W COB arrays powered our national stadium tour. TLCI > 95 held rock-steady across 60+ show nights, and the riggers loved how clean the beam edges stayed.
As an automotive OEM, the CRI > 95 white consistency across our 1800K–6500K range passed optical validation on the first try. That's a first for any LED supplier we've qualified.
The 8-channel build's 405nm FX channel gave our EDM festival a signature blacklight look the audience couldn't stop filming. Nobody else could hit that near-UV pop from a single engine.
