A19 vs. BR30 Bulbs – Which is Better for Your Needs?

August 20, 2025
Difference between A19 And BR30 light bulb in terms of shape and size

When it comes to choosing the proper lighting for your space, two popular options are A19 and BR30. Both of these LED bulb options are efficient and enhance the overall ambience of the setting. This article explains the differences between these bulbs to help you make the right choice. Let’s dive in!

All you need to know about A19 Bulb

A19 is a famous bulb code, which explains the shape and size of the bulb. The A in A19 explains the standard round shape of the bulb, and the numeric digit 19 helps in explaining the diameter of the bulb. The diameter is measured in eighths of inches, i.e., 19/8 = 2.375 inches. 

A19 bulbs are best known for providing an even omnidirectional light distribution. This omnidirectional light distribution makes them widely used in both commercial and residential properties.

A19 bulbs are often used in pendant lights

The E26 base is used in the A19 light bulbs. The letter E in the code explains that the base screw is an Edison bulb’s screw, and the numeric digit refers to the diameter of the base. This base type is commonly used in North America.

The compatibility of A19 with the E26 base and multiple other fixtures further contributed to the popularity of these household light bulbs. A19 vs E26 light bulbs are ideally used in homes to provide sufficient light for conducting daily routine tasks. 

Common light bulbs used in indoor and outdoor fixtures

A19 was initially available only as incandescent light bulbs. However, it is now available in fluorescent, Halogen, and LED versions. The table below mentions the pros and cons of A19 bulbs. Read them to make the right choice:

Works well with most fixturesLess efficient in recessed lighting
Available in smart/LED optionsNot ideal for a focused beam

All You Need To Know About BR30 Bulb

When you are in the market looking to purchase a bulb, you may have wondered what BR30 means on a light bulb. The answer to this question is that BR30 is a bulb code, which explains the bulb’s size, type, and shape

BR30 is a popular light bulb code. The BR in code explains that the shape of the bulb is rounded with a reflector to distribute light.

Whereas 30 indicates the diameter of the bulb. Diameter of BR30 bulb is also measured in eighths of an inch, i.e., 30/8 =3.75 inches. 

The BR30 bulbs emit a focused and wider beam of light. In contrast to A19, these bulbs are ideally suited for use in recessed cans, ceiling lights, and directional lighting. 

Even though this bulb is large, it still uses an E26 base. The table below explains some pros and cons of the BR30 light bulb:

BR30 ProsBR30 Cons
Ideal for flood lighting.Larger size, so it does not fit with all fixtures
Ideally used in recessed lightingLess versatile than A19
Available in smart optionsMore expensive 

A19 vs BR30: Key Differences You Should Not Ignore

A19 and BR30 bulbs differ from one another not only based on their shape, but also in terms of their light output, base type, efficiency, and fixture compatibility.

A19 and BR30 bulbs are among the typically used bulbs in residential settings

The key differences between these bulbs are explained below:

Shape & Size

The A19 bulb has a roughly pear-shaped design, similar to the classic Thomas Edison-style incandescent bulbs, measuring 2.375 inches in diameter. A19 bulbs are compact, lightweight, and fit well in lamps, kitchen pendant lights, and decorative lighting.

On the other hand, the BR30 bulb is longer, with a bulged reflector design and a 3.75-inch diameter. Its built-in reflector lens makes it ideal for directional applications. This reflector-type bulb is commonly used in recessed lights or track light setups.

Light Output & Beam Angle

The bulbs also differ from one another based on the light output and beam angle. A19 LED bulbs emit omnidirectional light, covering nearly 360°, making them ideal for ambient lighting in ceiling light fixtures, wall sconces, or bathroom vanities.

The BR30 LED lamps offer a wide beam angle of around 110°, delivering focused light. It is typically used to highlight specific areas or to highlight artwork.

Application Use

A19, BR30, PAR30, and GU10 are all efficient light bulbs; however, they serve different purposes. A19 bulbs are standard household bulbs with low wattage and compact shape, used in table lamps, ceiling fans, bedside lights, and other indoor lighting fixtures.

BR30 light bulbs, however, are used in recessed cans, kitchen spots, and track lighting.

Fixture Compatibility

A19 bulbs fit well with most light fixtures, including those with shallow bases. BR30 bulbs, however, are large and thus cannot fit in shallow and enclosed fixtures.

If you have enclosed fixtures, opt for A19 bulbs. If your fixture is large, choose BR30 LED bulbs instead.

A19 vs BR30 : Smart Features

With the advancement of LED technology, LED smart versions of A19 and BR30 have become popular. The smart versions of both these light bulbs have some common advanced features, including:

  • Voice control
  • App Sync
  • RGB color changing
  • Option to choose from different color temperatures, i.e, from 1800k to 6500k – from warm light to daylight color temperature

The smart BR30 bulbs are designed for recessed cans, particularly in ceiling or kitchen lighting applications. The focused light beam makes them best for task lighting.

However, with a slightly bulkier shape, these bulbs don’t fit well in shallow or decorative light fixtures.  

The compact shape of A19 bulb make them ideal for use in decorative lighting

The A19 smart bulbs are compatible with most common light fixtures. These bulbs are ideal for general lighting and for smaller spaces.

Can You Replace BR30 With A19?

Yes, you can replace a BR30 with an A19 bulb, but it is not ideal in all cases. A19 bulb is designed to spread light in all directions, whereas BR30 light bulbs offer a wide beam and are suitable for recessed ceiling can or directional lighting.   

So, in case you place an A19 bulb in a BR30 light fixture, the light may spread in unwanted directions and won’t deliver the same lighting result as a BR30. 

It is recommended to use A19 bulbs for general lighting and reserve BR30 bulbs for recessed lighting. Before switching, always ensure to check the fixture depth. A19 bulbs are small, so they may not fit well in a BR30 fixture. 

Quick Tip: A19 is not the best replacement for BR30, especially when light beam matters.

When to choose BR30 or A19 light bulb?

Choosing the right bulb type is a crucial task; one needs to evaluate the lighting needs, fixture type, and the required aesthetic before making a final decision.

 A19 vs BR30: Which One is Energy Efficient?

A19 & BR30 light bulbs replaced many other light bulbs

When purchasing any lighting source, buyers prefer the energy-efficient options. LED versions of A19 and BR30 bulbs are significantly more energy-efficient than halogen bulbs or incandescent bulbs. 

A19 LED uses around 9W and replaces traditional bulbs that use over 60W. A BR30 LED light bulb also uses around 9-12 W to replace a 75W incandescent bulb. 

If you’re looking for energy-efficient bulb options, be sure to choose those with an Energy Star rating. This certification ensures that the bulb meets high efficiency and performance standards.

Additionally, opt for bulbs that offer a high lumens per watt ratio, as they provide greater brightness while consuming less power.

Some commonly used light bulbs

Some LED bulbs also reduce blue light emission, which helps prevent eye strain and promotes better sleep. Additionally, the LED dimming feature helps save energy by adjusting brightness according to the user’s requirements.

Conclusion

A19 and BR30 bulbs suit different lighting requirements and are highly popular in both residential and commercial settings. Choose one of them that matches your lighting requirements. To reap the benefits of energy savings and other advanced features, opt for LED A19 or BR30 bulbs. Also, ensure that the bulb is compatible with your light fixture to avoid difficulties later on.
