The beam angles are where the differences really appear. ![]() The beam angle of each bulb affects the shape of the light produced. Note that BR bulbs tend to produce fewer shadows than a PAR. The soft-edge of the light beam produced by Sunco BR LED Bulbs will create a nice wall wash in interior light fixtures or a great downlight to illuminate a space in a recessed ceiling can. Some might say the edges are not as crisp. The light BR bulbs produce is of a softer quality. In other words, they cast a wide pool of light. Sunco BR bulbs produce a wide beam angle to illuminate a large area as directional flood lights. You will notice the bulging shape on our BR LEDs above the socket base (when looking at the bulb from the side like in the graph above). Traditional BR bulbs include a bulged reflector on the inside of the housing to increase light output. If you look across the entire lighting industry, specialty PAR lights are used in theatrical and film lighting, along with automotive applications. Instead of a bulbous shape, PARs tend to have a bowl shape, similar to those you use as vehicle headlights. PAR bulbs range between 2.48” to approximately 4.75” in diameter. However, Sunco PARs generate direct light with softened edge shadows. When compared to a BR light, PARs produce a crisper edge. Also, note that PAR bulbs tend to have a high lumen count to provide a bright light. PARs are more suited to exterior applications, some are even waterproof. PAR bulbs (Parabolic Aluminized Reflector) combine the lamp, reflector, and pressed lens into a single unit within the lamp. Also note: BR bulbs may extend past the end of a can, while PARs sit lower inside a recessed can, due to the variance in length. The physical shape of a PAR and BR bulb, including the diameter size (see chart below for more specs), is a quick way to identify a bulb. And you thought energy efficiency was the only difference between traditional bulbs and LEDs.Īlthough LEDs do not require a reflector, manufacturers continue to create the same bulb shape as the reflector bulbs you used to purchase in the past. Incandescent and other reflector bulbs still require that. ![]() LED bulbs do not require a reflector to produce the same light due to the technology used. The internal reflector of traditional PAR and BR bulb types redirects downcast light to the front of the bulb to make the most of the light produced. In addition, both Sunco PAR and BR bulbs feature CRI80 for accurate color rendering and clear definition of textures. You can swap these bulb types to change from wide to spot, depending on what you need in each location.īR and PAR LED replacements for your traditional flood or spotlight bulbs not only create a different style light beam from each other, the bulbs also look different. Notice that a PAR30 is the same diameter as a BR30 bulb. Example: BR30 = 30/8 inches or approximately 3 ¾” Diameter for these two bulb types is measured in eighths of an inch. The number indicates the diameter of the lamp portion, not the base of the bulb. Manufacturers use standard numbers like PAR30 or BR30 to indicate the bulb size. ![]() ![]() What do the Numbers on PAR & BR Bulb Names Mean? This blog will help you choose the right bulb for your next lighting project as you learn the differences between the bulb styles and varied sizes Sunco sells.
