A method and apparatus for a horticultural light that projects either a substantially uniform target illuminance onto a flat surface or an increasing target illuminance onto a flat surface. The horticultural light uses a refractor to receive the raw light distribution from one or more LEDs and then distributes an optically varied distribution having a minimized intensity at centerbeam with an increasing beam intensity as the beam width increases. The horticultural light utilizes both ultraviolet (UV) LEDs and non-UV LEDs arranged as an array to produce the optically varied distribution. A lens array is disposed in relation to the LED array and is comprised of UV compatible lenses and non-UV compatible lenses. A device may be disposed in relation to the UV compatible lenses to disallow incidence of UV radiation onto non-UV compatible lenses.
