Irradiance estimation for a 365 nm UVA LED with 1 Watt Radiant Power: Warning UV danger for eyes and skin

UVA radiation in the wavelength range of 200-400 nm of more than 10W/m² may cause inflammation of the cornea as well as a UV erythema (sunburn) of the skin. The biological effectiveness of the UV radiation varies in the stated wavelength range and is described with the spectral response function (weighting scale) SUV. 

Safety precautions when using UV light sources must be respected, as detailed in  IEC Standard 62471:2006, ‘Photobiological Safety of Lamps and Lamp Systems’, EU-Directive-2006-25-EC or the applicable standard for your country.
