The brightness of leds (light-emitting diodes) is generally expressed in Luminous Intensity, which is a Candela CD. 1000ucd =1mcd,1000mcd=1cd. The light intensity of a single indoor LED is generally 500UCD-50mcD, while that of a single outdoor LED is generally 100McD-1000McD, or even more than 1000McD. Wavelength, the distance between two consecutive points of the same phase at the same time in the direction of periodic wave propagation. LED light and radiation, light is electromagnetic radiation (energy travels from one object to another without any medium in the process. This mode of energy transmission is called radiation) reaches the eye and is converted by the optic nerve into light, the part of the spectrum that can be seen by the naked eye.
