Abstract
A light source for emitting emitted light to reduce microbial load, said light source, comprising: (a) at least one first light source for emitting first light having a peak wavelength less than 400 nm; and (b) at least one second light source for emitting a second light; wherein said emitted light comprises a combination of said first light and said second light, wherein said emitted light has a spectral power distribution (SPD), wherein said SPD has a first power in said SPD between 350 nm and 800 nm, and a second power in said SPD between 350 nm and 420, wherein said second power is at least 40% of said first power, and wherein said emitted light has a CRI of at least 80.
