Understand full-spectrum LED grow lights, blue, green, red, far-red and UV channels, and the data buyers should compare before sourcing.
What full spectrum means
Full spectrum is a broad industry term, not a single fixed recipe. Most horticultural fixtures combine white LEDs with optional deep-red or far-red channels. Compare the published spectral power distribution rather than relying on the label alone.
Blue, green and red
Blue light influences morphology and stomatal responses; green light can penetrate deeper into a canopy; red photons are efficiently used in photosynthesis. The useful balance depends on crop, stage, intensity and environment.
Far-red and UV
Far-red can influence phytochrome responses and canopy behavior. UV can trigger crop-specific responses but also creates exposure and material-safety considerations. Separate control and a measured trial are preferable to a universal claim.
What buyers should request
Ask for a complete spectral graph, PPF by wavelength band, actual input power, efficacy, crop-plane PPFD map, dimming behavior and the exact model configuration represented by the test data.
