In an indoor environment, in addition to the basic illumination required by plants, reducing the difference in light intensity on each leaf surface is a key factor to help plants to have a more balanced growth. The illumination of most lighting is mostly concentrated in the middle and top areas, creating a strong contrast with the peripheral light intensity. OURA’s 3D even brightness patented design effectively reduces the difference in light intensity received by leaves at different height positions, improving the evenness of the illumination, so that the plants’ appearance can be more natural and pleasing.
