Red-green-blue-amber-lime (RGBAL) light engines are evolving toward higher spectral quality, more channels, and smarter control, with a strong push from pro‑stage, film, and architectural applications. From RGBAL to multi-spectral Manufacturers are extending beyond RGBAL into 6–8 color engines (e.g., adding royal blue, deep red, indigo) to widen gamut and fix “gappy” spectra from older [...]
