light (within the range of 280-320nm), is normally received from the sun. When a plant detects UVB at 288nm, it produces the UVR8 protein. This protein acts as a chemical messenger which in turn, signals to the plant to secrete more oils and resins to help protect itself from the UVB rays.
Virtually no lamps produce UVB in the 280-320nm range due, in part, to the limitations of the glass. Solacure lamps are the sole exception as they use a type of glass designed specifically for transparency across the entire UVB spectrum.
This patented glass technology, combined with a unique blend of phosphors and high output, t makes Solacure lamps the most effective producers of UVA and UVB light, and the only lamps capable of triggering the full UVR8 effect.
