Nichia LED NWSU333B UV 4900mW 365nm 3500mA 3.5V Emitter 13W

Nichia is one of the largest LED manufacturers in the world and inventor of the blue (and thus also white) light emitting diode. The innovative Nichia research department is a pioneer when it comes to efficiency and establishes records on a regular basis.

Durability, brightness and homogeneity are among the major strengths of the Nichia brand. Furthermore, the fine selection allows greater added value for professional processing.

The Nichia SMD LEDs in the range UV light can be used for a wide range of applications. The NWSU333B is available with two different wavelengths, while at 365nm wavelength it reaches a power of 4900mW. 

Fixtures with multiple LEDs can be used for disinfection, plant growth, ink or resin curing, lithography for medical, industrial and commercial applications.

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.
