PAR16 LED Bulbs
Parabolic aluminized reflector (PAR) 16 LED bulbs are designed to control light more precisely. They produce about four times the concentrated light intensity of general service A shape incandescents. Like all light bulbs, the 16 value represents the diameter of the bulb in 1⁄8 of an inch. Therefore, a PAR 16 is 2 inches in diameter.
Unlike their halogen predecessors, PAR16 LED bulbs are more energy efficient and give off less heat as well. Most people know that since LEDs use less energy the cost of electricity to operate them is very low, and they can even reduce how much you use air conditioning in the summer months. Most PAR16 LED light bulbs are Energy Star certified, dimmable, and have a high CRI (color rendering index).
Due to their smaller size and narrower beam angle, PAR16 LED bulbs are very popular for use in track lighting, recessed lighting, display lighting, and pendant lighting. However, their most commonly found in jewelry stores, art galleries, and museums. They are even small enough to be used in antique cabinets and under cabinet lighting.
