## Abstract

A lamp including a first group of solid state light emitters that produce a general illumination light mode. The general illumination light mode is provided by a first range of light wavelengths emitted by the first group of solid state light emitters having a correlated color temperature ranging from 2700K to 6500K. The lamp also includes a second group of solid state light emitters that emit a second range of light wavelengths that are not visible to insects in a substantially insect free illumination light mode. The second range of light wavelengths have a spectral power ratio of wavelengths of less than substantially 550 nm to a total spectra of less than 700 nm, that is equal to 5.8% or less. The lamp further includes the ability to switch between the two modes of light.
