Understanding standard LED lights is crucial to answering this question. Most white LED lights combine red, green, and blue wavelengths using two primary methods: either mixing individual red, green, and blue LEDs, or coating a blue LED with yellow phosphor. The phosphor method dominates the industry due to its efficiency and superior quality for home lighting. It works by using yellow light to stimulate both green and red receptors in human vision, creating the perception of white light. While excellent for illumination, this approach delivers excessive green and yellow wavelengths while lacking the essential red spectrum that plants require for optimal growth.
Groxlum addressed this challenge by prioritizing the photosynthetic light spectrum first, then fine-tuning it to achieve premium white light quality!
