When something gives out light, it is called luminescence. This could be from artificial sources like light bulbs or natural sources like the sun or fire.
The word for something that gives out light without heat is "luminescent." The process is called luminescence, and the light produced is often referred to as "cold light."
The light that a torch gives out is typically called a beam or a beam of light.
An object that gives out its own light is called luminous. Examples include the Sun, fireflies, and lightbulbs.

No. It's what we see. (The amount it actually gives off is called the absolute magnitude.)
The sun is a natural source of light that provides warmth and illumination to Earth.
Bioluminescence - if it gives of visible light. However heat is also light and metabolism itself therefore gives off light, but you can not see it because it is infrared light.
Compromise - an agreement reached where each side gives up something is called.
