Spectral Options

Full-Sunlight Spectrum: Broadband white light (380–730 nm) combining 6000K (cool white) and 3000K (warm white) LEDs, closely mimicking natural daylight with enhanced red and far-red continuity. CRI >90, suitable for full-cycle plant growth.
Targeted Red-Blue (RB) Blend: Optimized ratio of 60% deep red (660 nm) + 40% blue (450 nm) for vegetative vigor and compact morphology; ideal for seedling, propagation, or energy-efficient supplemental lighting.
Advanced Full-Spectrum + FR: Full-sunlight base with added far-red (730 nm) for photomorphogenic control (shade avoidance, flowering acceleration) – available on select models.
All above are standard configurations. Custom spectral recipes (e.g., 70/30 RB, UV inclusion, tunable white, or multi-channel control) are available upon request for commercial or research applications.
