What type of light is produced by an ordinary light bulb and yields red tones?

Incandescent light is produced by heating a filament until it glows, resulting in a warm light that yields red and yellow tones. This type of light illuminates spaces with a softer, more diffuse glow, which is often considered flattering in various settings, including homes and salons. The characteristic warmth of incandescent bulbs contributes to the red hues they produce, making them popular in environments where a cozy atmosphere is desired.

In contrast, fluorescent light typically emits cooler, more clinical tones, often leaning toward bluish hues due to the type of gas and phosphor used. LED light is known for its energy efficiency and versatility but often produces white or cool tones rather than the warmer reds. Halogen light, which is a type of incandescent bulb, provides bright light and higher efficiency but can lean more toward white and bright yellow tones rather than the softer reds. Understanding these properties helps estheticians choose the appropriate lighting for different treatments and skin assessments.
