Lighting Science LED PAR16 - 25 Degree Beam

Useful for accent or task lighting, our energy efficient PAR LED bulbs (PAR is short for parabolized aluminum reflector) make great replacements for your hot-running halogen incandescent bulbs. They can be used indoors or outdoors in applications such as downlights (commonly referred to as ceiling can lights) or home security lighting.

How to tell the size of the PAR LED bulb you want to replace: The number following the PAR designation relates to the bulbs diameter in an unusual way. It represents the number of eights of an inch (1/8) that compromise the diameter of the bulb. For instance, a PAR38 LED bulb measures 4.75 inches in diameter (38/8 = 4.75). Or a PAR16 LED bulb measures 2 inches in diameter (16/8 = 2). This is a useful tip when the bulb you are trying to replace doesnt have markings indicating what size of PAR bulb it is.
