<h2>The layers of the Sun</h2>
There are three inner layers as the Core, Radiative Zone and Convection Zone. The external coatings are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will adjust its research on the Chromosphere and Transition Region. The above three are only the layers of the Sun.

High heat lighting is that with the lowest number of degrees Kelvin and high red spectrum is generally defined as radiation with wavelengths between 600 and 700 nm.
<h3>What is warm lighting?</h3>
Warm light is the one with the fewest degrees Kelvin, typically around 2,700K, bringing in light that is pulled yellow.
<h3>What is red spectrum light?</h3>
Red light is generally defined as radiation with wavelengths between 600 and 700 nm. Although red light has a low luminous efficiency, which means the light appears relatively dim to people, it has a high relative quantum efficiency and is highly absorbed by the red-absorbing (PR) form of phytochrome.
With this information, we can conclude that red light has a low luminous efficiency, which means the light appears relatively dim to people.
