CyanLight

CyanLight is a term used in the lighting industry to describe light sources that emit cyan-colored light, typically in the 490 to 520 nanometer range. The label is applied to LEDs and lamp arrays that have spectral output concentrated in the cyan portion of the spectrum, and it is also used as a brand name by various manufacturers for product lines emphasizing cyan hues.

Technically, CyanLight devices may use cyan-emitting LEDs directly, or phosphor-converted white LEDs with spectral tuning that emphasizes cyan. The design often aims for high color saturation and adequate color rendering, with some products offering tunable white balance and adjustable intensity. Spectral purity and light output efficiency are common performance metrics.

Applications include architectural and stage lighting where cyan accents create cool, contemporary aesthetics, as well as signage, aquarium lighting, and specialized displays. In horticulture, cyan wavelengths are sometimes combined with other spectra to support certain lighting recipes, though cyan alone is not a universal requirement for plant growth.

Because CyanLight is not a standardized technology, specifications vary by manufacturer. Users should review spectral distribution, color rendering index, efficiency, and control options when selecting CyanLight products.
