A full-spectrum LED grow light is simply a marketing term that implies that your grow light closely resembles light from the sun. This marketing term comes from the concept of “full-spectrum light,” which in recent years has been used to refer to electromagnetic radiation from the UV to infrared wavebands.
What color LED is full spectrum?
LED luminaires that emit a “white” light are often referred to as “broad spectrum” or “full spectrum” lights because they include a broad band of the light spectrum (more similar to the sun) which renders a “white” light (there are no true white wavelengths).
How do I know if my LED light is full spectrum?

Which color light is best for plant growth?
What Color Light is Best for Plant Growth?
- Violet-blue light in the 400 – 520 nanometer range encourages chlorophyll absorption, photosynthesis, and growth.
- Red light in the 610 – 720 spectrum range promotes flowering and budding.
How do you use a full spectrum LED grow light?
Rather than bogging down in botany, keep your growing simple by following three guidelines: use full-spectrum LED grow lights for all cycles, keep them on at least 18 hours during vegetative growth, and cut back to 12 on and 12 off for flowering. Then sit back and enjoy your harvest.
What led grow light should I buy?
A good rule-of-thumb for LED grow lights is 32 watts of actual wattage per square foot of growing space for flowering medical or other large flowering plants. Vegetative growth for high-light plants need about half this wattage.).
