Several LED bulb designs available on the market today were adopted from traditional lighting standards, during the era of incandescent and halogen luminaries. For homeowners looking to switch over to LEDs, it is important to know about conventional bulb sizes, to ensure compatibility during installation. With this in mind, this article compares the differences between a LED PAR 30 and a BR 30 LED bulb.

Characteristics and Angles

A PAR 30 LED bulb provides spotlighting features, with tight angles lower than 45 degrees. The acronym ‘PAR’ stands for Parabolic Aluminized Reflector. These types of LED bulbs can be used indoors and outdoors, depending on the ratings of the unit. PAR LED products may be offered at various angles, such as: narrow spot, narrow flood or wide flood. These options range from 5-15 degrees to 45 degrees.

A BR 30 LED bulb offers the opposite lighting characteristics, compared to a PAR 30 LED bulb, in a sense that the angles are noticeably wider. This is easily distinguishable, based on the term ‘BR’ which stands for Bulged Reflector. This type of LED bulb provides lighting angles wider than 45 degrees.

LED Applications

Based on the lighting characteristics of the LED bulbs, we can determine their respective applications. PAR 30 LED units illuminate specific objects or targets, making them ideal for track lighting systems, illuminating landscapes, paintings and general security lighting. It is important to highlight that when the bulb is used outdoors, they must carry specific waterproof ratings.

A BR LED bulb is useful for lighting up wide spaces inside homes. Such objects and locations include living rooms, kitchens, hallways and doorways. To maximize the unit’s beam spread, it is recommended to use this type of LED bulb with recessed lighting configurations or with lighting guards, especially with BR LED bulbs that offer very wide lighting angles.
