Incandescent Bulb: This bulb emits light through the heating of a filament wire. It is usually seen as inefficient because it heats up a space.
Fluorescent Bulb: Fluorescent bulbs do not emit any heat. Historically, their light was seen as unflattering and cool, but now they come in warmer tones. They use much less electricity and are more energy-efficient.
Natural Lighting: Sunlight has a full spectrum of colors. This type of lighting changes in temperature depending on the season and the time of day. It has a direct effect on reflective surfaces and colors used in a space.
