Blue 450nm LED Dome Lens SMD LED 60-Degree

What color is 450nm light? 

For both blue SMD LED and blue through-hole LED,  they all name as blue LED that emits blue color. The wavelength range of blue LED are from 440nm to 490nm. Which means blue wavelength are between UV LED color and green LED color. When the color goes longer, the color of light will be greener and when we wavelength of blue LED close to UV LED, the color will go deeper and purpler. 460nm LED are the pure blue. Comapre with 460nm or 470nm LED, the light color of 450nm LED will be deeper and purpler. People name it as royal blue or deep blue. 

Size of Dome Lens SMD LED 60 Degree LED;

*Soldering confition: Soldering confition must be completed with 3 secongds at 260℃

*Luminous intensity is measured by ZWL600.

*λD is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
