Led white spectrum
NettetSPD is the Spectral Power Distribution of a light source. The visible white light that we see is made up of a spectrum of various colors of light, ranging from wavelengths of 380nm (violet) to 760nm (red). The SPD is a graph that shows the power (strength) of each wavelength of light produced by a particular light source. Nettet16. feb. 2024 · So, for example, full-spectrum lights that fall in the “warm” part of the category are giving off more yellow light. In contrast, “cool” lights have more of a blue or white color. This means that bulbs that are just labeled “daylight” tend to have more blues in their color makeup, as that’s what we associate with them.
