April 14, 2025
br40 vs br30

Struggling to choose between BR30 and BR40 LED bulbs or BR LED replacement lamps for your setting? If you want to illuminate a house, office, or business space, we will walk you through options that are appropriate for you.

This article guides you to the proper decision by considering size, light output, correct color rendering index, and use. Let’s start

The Increasing Demand for LED Lighting

LED lighting has rapidly become the norm for both residential and commercial use. More than 50% of American households already use LED bulbs, and the direction is obvious—individuals desire to be energy-efficient, longer-lasting, and cheaper.

LED lighting is gaining popularity in both residential and commercial areas

This increased demand makes homeowners and companies question what is ideal for their lighting needs. The latest technology uses LED with BR lighting, specifically featuring bulged reflector designs.

The most popular replacements are BR20, BR30, and BR40 LED bulbs with more focused lighting. Companies are learning about BR lighting, BR bulb sizes, and techniques.

As similar as they are, the one that will work best for you will depend on the size of your area, the level of brightness you need, and the application.

It is a wise decision to learn everything about BR and LED lights, including the beam spread, pros and cons of LED and BR, to make a wise decision.

What is a BR30 and a BR40 Bulb?

BR bulbs—”Bulged Reflector” bulbs—are designed to concentrate light using a parabolic reflector into a beam and are a stalwart of track lighting and recessed lighting.

The number that comes after the “BR” tells us about the bulb’s diameter in eighths of an inch, and this designation indicates the diameter.

A BR30 bulb is 3.75 inches in size, and its bulb shape concentrates light, making it mostly installed in small cans (approximately 4 to 5 inches). It is best suited for use in the kitchen, office, and bathroom, where it requires a stronger light source.

A BR40 bulb measures 5 inches in length. It is better for large recessed cans (typically 6 inches and larger) and is more appropriate for larger areas such as living rooms, hallways, or offices where broad, even lighting is needed.

BR30 is also used in Cans lighting, accentuating large objects as well. So, make sure to go through cans of lighting vs. recessed lighting before ordering in bulk.

Main Differences Between BR30 and BR40 Bulbs

The following differences between BR30 and BR40 bulbs will help you make the best choice for your environment.

Difference in Size

The most obvious distinction between the BR families is diameter. BR30 has a diameter of 0.3 feet or 3.75 inches and is ideal for small recessed lighting cans. There are some other types of recessed lighting where BR LED lamps can be used.

BR40 is 5 inches and intended for large fixtures. The diameter will affect not only appearance but also functionality.

BR30 bulbs emit 650–800 lumens with a focused beam angle of around 40–45 degrees, achieved through directional photometry principles. They are, therefore, most appropriate to task or accent light fixtures in small spaces.

BR40 bulbs emit 1100–1300 lumens with a wide beam angle of up to 100 degrees using reflector par parabolic aluminized, perfect for lighting large spaces with smooth, even coverage.

Power Consumption

Both BR30 and BR40 bulbs now have their energy-efficient new LED versions. In contrast to those wasteful old incandescent BR40 bulbs, LED saves more energy per month.

The new LEDs consume around 9–12W for BR30 and 12–15W for BR40, which are fairly priced alternatives that sacrifice no aspect of lighting.

How to Choose Between BR30 and BR40 for Your Space

Having the right bulb involves a lot to do with your room size, ceiling height, and the level of light you’d like.

For Small Rooms

In small areas like kitchens, offices, or hallways, BR30 will be a fabulous option. Given its narrow beam and less luminous output in terms of lumens of light, the BR30 is optimized for applications requiring lower illuminance levels.

It renders good light but doesn’t dominate small spaces.

For Large Spaces

For open-plan spaces, malls, or large living rooms, BR40 provides wider coverage. The greater beam angle and brightness make the light travel farther, illuminating more space with better efficiency.

For large areas like malls BR40 is a good choice

Ceiling Height Matters

BR30 works well for standard ceilings of 8 to 10 feet, especially with a good color rendering index. For ceilings greater than 10 feet or for spaces requiring more illumination—galleries, showrooms—use BR40.

BR40 bulbs, which often utilize reflector parabolic aluminized designs, are largely used by businesses to illuminate large spaces like warehouses, corporate reception spaces, or conference rooms where brightness and evenness are the most important factors.

Performance Features: Luminescence, Power Efficiency, and Longevity

LED BR30 and BR40 bulbs offer better performance with less power consumption.

Energy Savings

The two bulbs consume 25% to 75% less power than standard incandescent bulbs due to their higher luminous efficacy. That means substantial operating cost savings in the long term, particularly on multi-fixture installations.

Durability

BR30 and BR40 LEDs both have a shelf life of 25,000 to 50,000 hours. Lower replacement frequency translates to lower maintenance and higher long-term reliability on residential and commercial installations.

Dimming Capability

Dimmable bulbs and dimmers, BR30s are perfect for ambiance lighting. Dimming saves energy and provides extra bulb life with ambiance adjustability as a plus by leveraging phase-cut dimming technology.

Cost Analysis: Initial Cost vs. Long-Term Savings

Although LED bulbs are seen to cost a bit more to buy, their long-term savings warrant them as an outlay to be paid.

Initial Cost

BR40 bulbs will cost a few dollars more than BR30 because of size and light output, being an improved version of R lamps.

Energy Savings

Using a 50-BR40-bulb setup where the bulged shape concentrates the light at the center of the beam saves more energy cost per year (at $0.12/kWh) and is significantly lower with this new technology—saving hundreds of dollars annually.

ROI

LED BR bulb replacement is at a cost-justifiable point in time through energy savings and less replacement, particularly in high-use applications such as hotels, offices, or retail.

Compliance & Certification: What to Look for in Commercial Lighting Solutions

Certifications become an issue when making decisions about light distribution and lighting used in commercial use.

DLC and UL Certifications

Look for bulbs that have DDL and UL certification. These marks guarantee energy efficiency, performance, and conformance to standards of safety and quality.

Why Certification Is Necessary

Certified products, including those using a multifaceted R reflector BR bulged, are eligible for rebates from local utilities, conserve energy, and meet building codes that justify the investment for business process lighting applications.

Selecting the Best BR30 and BR40 Bulb Supplier

The ideal supplier is as crucial as the ideal bulb.

Purchasing in Bulk

For companies selling to many locations or big buildings, select suppliers that offer a version of BR lamps at bulk price and quick fill. Make sure to see the charts of bulb size, type, shape, code, and other important stuff to make a well-informed purchase.

Custom Services

Pick suppliers that provide wattage, beam angle, or color temperature customization to fit your application.

Warranty & Support

3- to 5-year warranty and experienced support personnel provide comfort in case of technical failure or inadequacy.

FAQs

Q1: Will a BR30 bulb fit a BR40 fixture?

Answer: A BR30 can be used in a BR40 fixture because it is smaller, but there would be a gap showing and less coverage of light.

Q2: What is the greatest difference between BR30 and BR40?

Answer: The greatest difference is in size—BR30 is 3.75″ wide, and BR40 is 5″. BR40 has a broader, softer light spread.

Q3: Is BR30 or BR40 better suited for recessed lighting?

Answer: BR30 is utilized on 4″/5″ cans and focused lighting. BR40 is better for 6″ cans and wide areas since it produces a wider beam.

Q4: Are bulbs labeled BR30 and BR40 of the same base?

Answer: Yes, they both typically contain the standard base E26, so they will fit into the same sockets, just like other LED lights.

Conclusion

Both BR30 and BR40 bulbs have a great use in lighting design currently, as each lamp has a nominal size that suits specific tasks. Use your space measurements, ceiling height, and performance needs to make the most informed choice.
