How does the Lumen output of the LED-PlantBar compare to other grow lights?
Lumens and lux are measurements of how bright a light source appears to the human eye. Since the human eye is most sensitive to colors plants don’t need, and least sensitive to colors plants prefer, Lumens can’t be used to accurately compare the plant growing capability of grow lights. If a grow light manufacturer rates his grow light output in Lumens he’s only telling you how bright his grow light will appear to you and light your room, not how well it will grow your plant.
