PAR30 and PAR20 bulbs are two types of bulbs commonly used for lighting purposes. While they are both part of the PAR (parabolic aluminized reflector) family of bulbs and serve the same general purpose, there are some differences between the two that make them suited for different applications.
PAR30 bulbs are larger and brighter than PAR20 bulbs. They have a diameter of 3.75 inches and a length of 4.62 inches, which means they are ideal for use in larger spaces such as living rooms, kitchens, and offices. They also have a wider beam angle, typically around 40 degrees, which means they spread light evenly over a larger area.
On the other hand, PAR20 bulbs are smaller and less bright than PAR30 bulbs. They have a diameter of 2.5 inches and a length of 3.5 inches, making them more suited for use in smaller spaces such as bedrooms, bathrooms, and hallways. They also have a narrower beam angle of around 30 degrees, which makes them better for directional lighting applications such as accent lighting.
Another difference between the two types of bulbs is their wattage. PAR30 bulbs typically have a higher wattage, usually ranging from 35 to 75 watts, while PAR20 bulbs have a lower wattage range of around 20 to 50 watts. This means that PAR30 bulbs are able to produce more light and are generally considered more energy-efficient than PAR20 bulbs.
In terms of pricing, PAR30 bulbs are generally more expensive than PAR20 bulbs due to their larger size and higher wattage. However, since they are more energy-efficient, they can save you money on your electricity bill in the long term.
In conclusion, the main difference between PAR30 and PAR20 bulbs is their size, brightness, and beam angle. PAR30 bulbs are larger and brighter, with a wider beam angle, making them ideal for larger spaces, while PAR20 bulbs are smaller and less bright, with a narrower beam angle, making them better suited for smaller spaces and directional lighting applications.
