Which statement is true about the characteristics of incandescent lighting?

Incandescent lighting is known for producing a warm light effect with a significant output of red and yellow wavelengths. This characteristic makes them rich in warm colors, and they emit a broader spectrum of light, including a fair amount of blue wavelengths, though not as much as some other light sources like LED or fluorescent lights.

Choice B accurately captures this aspect of incandescent lighting. The perception of warmth in incandescent bulbs stems from their higher emission in the red and yellow parts of the spectrum compared to blue. This creates a cozy and inviting atmosphere, which is often desirable in residential and hospitality settings.

The other options suggest characteristics that do not align with the nature of incandescent lighting. They tend to emit higher temperatures compared to other sources like LEDs, create a warm light effect rather than a cool one, and are recognized for their warmth in color, not for lacking it.
