What is the Difference Between Incandescent and Fluorescent Light Spectrums?

The main difference between incandescent and fluorescent light spectra lies in the distribution of colors in the spectrum. Here are the key differences:

• Incandescent Light Spectrum: Incandescent light bulbs produce a continuous spectrum, which means all visible colors are present. This type of light is often considered more uniform and evenly distributed, providing a warm, white light.
• Fluorescent Light Spectrum: Fluorescent light bulbs produce an emissions spectrum, which consists of discrete parts of the spectrum and is punctuated by lines. This type of light spectrum is less uniform than that of incandescent light bulbs, with shorter wavelengths and fewer colors present.

The difference in the spectra of these two light bulbs is due to the way they produce light. Incandescent light bulbs use a wire filament that glows when heated, while fluorescent light bulbs rely on a chemical reaction between mercury and a phosphor coating inside the bulb. Additionally, fluorescent lights are more energy-efficient than incandescent lights, as they produce the same amount of brightness with less energy consumption.

Comparative Table: Incandescent vs Fluorescent Light Spectrums

The main differences between incandescent and fluorescent light spectra are their spectra and energy efficiency. Here is a table comparing the two:

Incandescent light spectra are continuous, meaning they include all visible colors in varying percentages. In contrast, fluorescent light spectra are composed of discrete lines typical of the mercury spectrum and the phosphor. Incandescent lights are less energy-efficient than fluorescent lights, producing 16 lumens per watt compared to the 50-100 lumens per watt of fluorescent lights. Incandescent lights produce a warmer, white light, while fluorescent lights emit a cooler, yellowish light.
