Frequently Asked Questions

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.
