A light emitting diode (LED) lighting system includes a base, a power supply on the base, an LED module on the base having one or more LED dice configured to emit electromagnetic radiation having a selected wavelength range, and multiple interchangeable wavelength conversion lenses configured for removable attachment to the base in light communication with the LED module. Each lens has a different configuration such that the lenses can be changed to vary the electromagnetic radiation output of the light emitting diode (LED) lighting system. The wavelength conversion lenses can be separate from a cover for the light emitting diode (LED) lighting system or can be formed directly on the cover.
