1. A light source for emitting emitted light to reduce microbial load, said light source, comprising:
at least one first light source for emitting a first light having a peak wavelength less than 400 nm; and
at least one second light source for emitting a second light, said second light being white light having a second light Color Rendering Index (CRI);
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 an emitted light CRI of at least 80; and
wherein said emitted light CRI is less than said second light CRI but no less than 80% of said second light CRI.
