Abstract
A light emitting diode lamp includes a light source configured to emit light that defines a spectral power distribution curve including a first power peak and a second power peak with a first reduced power area extending therebetween. The first reduced power area defines a first reduced power area minimum in a green color region of the spectral power distribution curve and the spectral power distribution curve compares a power of the light versus a wavelength of the light.
