Incandescent – This is the type of light bulb most people think of and is the most common type. It is easy to use, fits in many fixtures, and is usually the least expensive. This light bulb type has a warm and soft light and does not bleach out or discolor skin tones and other colors.
Halogen – This is a variation of the incandescent. Halogen bulbs produce what is known as a white light and is the closest we can get to natural daylight. It is important not to handle these bulbs with your bare hands. They get so hot that the oil from your hands can cause hot spots to form on the bulb, which can cause them to shatter or explode.
Fluorescent – These bulbs give off a flat, cold light that is often described as being bluish in color and it can be very harsh on the eyes. It is similar to daylight but cannot be put on dimmer switches. There are many types of fluorescent light bulbs available. Fluorescent bulbs work well to light large areas.
Compact Fluorescent Bulbs (CFLs) – This is a light bulb type that consumes a quarter of the energy needed to light the standard incandescent bulbs and they will also typically last 10 times longer. Unlike the other types, these bulbs have warmer, color-corrected tones so they do not discolor and affect light quality.
LED – LED stands for "light-emitting diode," and is long-lasting and extremely energy-efficient, and burn cold to the touch. They are best used for spot lighting such as under a display case or such, but not where diffused light is needed — like in a bedroom.
