Incandescent light is known for its ability to produce a warming effect on the skin primarily due to its heat output. This type of light generates warmth because it emits a significant amount of thermal radiation along with visible light. Incandescent bulbs work by heating a filament until it glows, resulting in a spectrum of light that includes infrared rays, which contribute to the sensation of warmth when it comes into contact with the skin.

While fluorescent light operates differently, primarily by exciting gas to produce light with less heat, it does not provide the same warming effect. LED light, depending on its design, can also emit less heat and is more energy-efficient, focusing more on specific wavelengths of visible light rather than generating warmth. Natural light from the sun can indeed provide warmth, but its intensity can vary greatly depending on factors like time of day, weather conditions, and geographic location, making it less predictable for consistent heating compared to incandescent light. Thus, incandescent light remains the most reliable source for producing a warming effect.
