Which type of light bulb is described as high in yellow and providing warm light?

Incandescent bulbs are known for producing light that is high in yellow and offers a warm glow, which is often associated with a cozy and inviting atmosphere. This warm light is a result of the way incandescent bulbs work; they produce light by heating a tungsten filament until it glows, emitting a spectrum of light that includes a lot of yellow and red hues in its color temperature range, typically around 2700K to 3000K. This characteristic makes incandescent bulbs popular for residential settings and areas where a warm ambiance is desired, such as living rooms and dining areas.

In contrast, fluorescent bulbs often emit a cooler light while LED bulbs can provide a range of color temperatures, including cool and warm, depending on their design. Halogen bulbs, while also producing a bright light, tend to have a whiter light spectrum and are not classified predominantly as ‘warm’ light in the same way that incandescent bulbs are. Thus, the warm, yellowish light characteristic of incandescent bulbs confirms them as the correct answer to the question.
