What is the best UV light to kill mold?
The type of UV light that’s able to kill mold is UV-C, which has a short wavelength. UV-C lamps are effective at disinfecting air ducts, air conditioners, and other indoor spaces that attract mold spaces. UV-C lamps are also called germicidal lamps because they are able to disinfect even air and non-porous surfaces.
Does mold react to UV light?
The aiming angle with a blacklight
You should shine the ultraviolet light closely along the sides of the suspected surface or walls. The angle of illumination will show the presence of fungus easily, without much effort.
Will UV-C kill mold?
If properly designed, ultraviolet germicidal irradiation (UVGI) cleaners that use ultraviolet radiation from UV lamps may destroy indoor biological pollutants such as viruses, bacteria, and some molds that are growing on the moist interiors of HVAC surfaces (e.g., cooling coils, drain pans, or ductwork).
Does UV light kill mold in HVAC?

Will LED light kill mold?
LED light is killing bacteria, fungus and mold, and the scientific community has validated the results. Lab researchers, diode fabricators and fixture manufacturers are working to market LEDs that are an effective and safer disinfectant than ultraviolet (UV) light, while also offering a much longer operational life.

Does UV light kill Candida?
Methods: Candida auris was seeded on glass slides and exposed to UV-C for 5, 10, 20 and 30 minutes at 2 and 4 m. Results: A maximal effect of C auris killing was found after 30 minutes of UV-C exposure at 2 m. With half the time or twice the distance, the efficacy strongly diminished to ~10 and ~50 fold, respectively.
