The Ultimate Guide to PAR Bulbs: PAR16, PAR20, PAR30, PAR38

When it comes to lighting, there are many different types of bulbs to choose from. One popular option is the PAR bulb, which stands for "parabolic aluminized reflector." These bulbs are known for their directional lighting and are commonly used in track lighting, recessed lighting, and floodlights. In this article, we will explore the different types of PAR bulbs, including PAR16, PAR20, PAR30, and PAR38, and their uses.

What are PAR Bulbs?

PAR bulbs are a type of halogen or LED bulb that features a parabolic reflector to control the direction of light. This means that the light is focused in a specific direction, making them ideal for accent lighting or highlighting specific areas. PAR bulbs are available in a variety of sizes, with the number after "PAR" indicating the diameter of the bulb in eighths of an inch. For example, a PAR16 bulb has a diameter of 2 inches.

PAR16 Bulbs

PAR16 bulbs are the smallest of the PAR bulbs, with a diameter of 2 inches. They are commonly used in track lighting, recessed lighting, and display lighting. These bulbs are available in both halogen and LED options, with the LED bulbs being more energy-efficient and longer-lasting. PAR16 bulbs are also available in different beam angles, allowing you to choose between a narrow spotlight or a wider floodlight.

PAR20 Bulbs

PAR20 bulbs have a diameter of 2.5 inches and are slightly larger than PAR16 bulbs. They are commonly used in recessed lighting, track lighting, and display lighting. PAR20 bulbs are available in both halogen and LED options, with the LED bulbs being more energy-efficient and longer-lasting. These bulbs are also available in different beam angles, allowing you to choose between a narrow spotlight or a wider floodlight.

PAR30 Bulbs

PAR30 bulbs have a diameter of 3.75 inches and are larger than PAR16 and PAR20 bulbs. They are commonly used in recessed lighting, track lighting, and floodlights. PAR30 bulbs are available in both halogen and LED options, with the LED bulbs being more energy-efficient and longer-lasting. These bulbs are also available in different beam angles, allowing you to choose between a narrow spotlight or a wider floodlight.

PAR38 Bulbs

PAR38 bulbs have a diameter of 4.75 inches and are the largest of the PAR bulbs. They are commonly used in floodlights, outdoor lighting, and security lighting. PAR38 bulbs are available in both halogen and LED options, with the LED bulbs being more energy-efficient and longer-lasting. These bulbs are also available in different beam angles, allowing you to choose between a narrow spotlight or a wider floodlight.

Choosing the Right PAR Bulb

When choosing a PAR bulb, it is important to consider the size and purpose of the space you are lighting. For smaller areas, such as display cases or track lighting, a PAR16 or PAR20 bulb may be sufficient. For larger areas, such as outdoor lighting or floodlights, a PAR30 or PAR38 bulb may be more appropriate. It is also important to consider the beam angle of the bulb, as this will determine the spread of light.

Conclusion

PAR bulbs are a popular choice for directional lighting, offering a focused and controlled beam of light. With options ranging from PAR16 to PAR38, there is a PAR bulb for every lighting need. When choosing a PAR bulb, consider the size and purpose of the space, as well as the beam angle, to ensure the best lighting solution for your needs.
