Question

How do the spectra of the different types of light bulbs compare?

Incandescent light bulbs emit absorption spectra similar to the spectra of stars. CFLs and LEDs emit the light in the broad bands near specific wavelengths.

Incandescent light bulbs emit absorption spectra similar to the spectra of stars. CFLs and LEDs emit the emission line spectra with specific wavelengths.

Incandescent light bulbs emit generally continious thermal spectra. CFLs and LEDs emit the emission line spectra with specific wavelengths.

Incandescent light bulbs emit generally continuous thermal spectra. CFLs and LEDs emit the light in the broad bands near specific wavelengths.
