It depends on the type of light. Both Fluorescent lights and LEDs initially emit light in the UV range or near-UV range (high energy). This light is then absorbed by compounds which re-emit the light at longer wavelengths (lower energy). The difference in energy between what the compound absorbs and what it emits is dissipated as heat.
Different compounds emit different wavelengths when excited by UV light. By using a cocktail of compounds, a wide variety of wavelengths can be emitted, producing a spectrum that is very similar to that of natural light.
Full spectrum LEDs use a different compounds than fluorescent lights do, but the concept is the same.
Full spectrum lights are different from many so called white lights in that white lights usually emit only three or four discrete wavelengths. The eye averages the different wavelengths together to give the perception of color. If the ratios between the intensities of the wavelengths is just right, the light appears white.
incandescent light working principle is very simple. it is working in the current passing thought a filament the filament produce a large amounts of heat the heat to burn the filament .blowing of filament to generate light . incandescent using more power comparing fluorescent t lamp incandescent lamp are not energy efficient
A laser is a device that generates a beam of coherent light. Coherent light is light in which waves have the same wavelength throughout, and the crests and troughs are the same. Laser light is emitted when excited atoms of a solid, liquid, or gas emit photons.
Led rely on semiconductor heterostructures emitting electrons removed by barrier energy of the electrons in the direct light.
Any natural light bulbs that use incandescent lighting will work well, and give off a rounder light than the "sterile white" lighting of normal bulbs.
I have not had any problem obtaining incandescent light bulbs.

The costs of manufacturing costs of fluorescent and incandescent light bulbs are about the same aside from the slight different materials.

Argon(or nitrogen) and tungsten are used in incandescent light bulbs.

Incandescent light bulbs are the most common type of light bulb in the average home. Chances are, if you look up, you'll see one. They're used for just about everything. N.B.: The light bulbs that look like long tube are fluorescent, not incandescent.

Halogen light bulbs are what has been around for a very long time. Incandescent bulbs are new and are more energy efficient.
