Blue and Red LEDs are very good for plant growth. They are low power and high
intensity.
Our bulbs are brighter than bulbs that cost more than twice as much. In fact our bulbs have more diodes (210) and are brighter than any that we know of.
The LEDs are at 100% density. This is what high light intensity plants want.
We have done a lot of research and strive to always bring the best bulbs to you.
