Ever stood in the lighting aisle, staring at boxes labeled BR30 and R30, wondering what the heck the difference is? You're not alone. These two bulb types look pretty similar at first glance, but they actually work quite differently in your home.
The truth is, picking the wrong bulb can leave your rooms looking dim or wasting energy. But don't worry - I'm going to break down everything you need to know about br30 vs r30 bulbs so you can make the smart choice for your space.
Key Takeaways
Before we dive deep, here's what you really need to know:
- BR30 bulbs have a bulged reflector design that spreads light wider
- R30 bulbs are simple reflector bulbs with more focused beams
- Both are 30/8 inches (3.75 inches) in diameter
- BR30 works better for general room lighting
- R30 is ideal for accent lighting and task areas
- Energy efficiency is similar between both types
- BR30 costs slightly more but offers better value
What Does BR30 Actually Mean?
Let's start with the basics. BR stands for "Bulged Reflector." The 30 refers to the diameter in eighths of an inch - so 30/8 equals 3.75 inches across.
The bulged part is key here. These bulbs have a wider, rounded shape that helps spread light more evenly across a room. Think of it like a flashlight with a wide beam versus a narrow one.
Understanding R30 Bulbs
R30 is simpler - it just means "Reflector 30." These bulbs also measure 3.75 inches in diameter, but they have a more traditional shape without that bulge.
The reflector coating inside bounces light forward in a tighter pattern. This creates what lighting folks call a "narrower beam angle."
Complete Comparison Table: BR30 vs R30
Here's everything laid out side by side so you can see the real differences:
| Feature | BR30 | R30 |

| Availability | Very common | Less common now |
| Ceiling Height | Works great in 8-12 foot ceilings | Better for higher ceilings |
The Design Differences That Actually Matter
Shape and Structure
When you look at these bulbs side by side, the BR30's bulge is obvious. It curves out more, kinda like the difference between a basketball and a football.
This bulge isn't just for looks. It changes how light escapes the bulb and spreads through your room.
Internal Reflector Design
Both bulbs have reflective coatings inside, but they work differently:
BR30 bulbs use a stepped reflector design. The bulge creates more surface area for reflecting light outward at wider angles.
R30 bulbs have a simpler, smoother reflector that keeps light traveling in a straighter path.
Light Output and Performance Comparison
Beam Angles Explained Simply
This is where things get practical. Beam angle determines how wide your light spreads.
BR30 flood lights typically offer:
- 100-120 degree beam spread
- Light reaches corners of rooms
- Creates ambient, general lighting
- Reduces shadows and dark spots
R30 spot lights usually provide:
- 60-80 degree beam spread
- More concentrated light pool
- Better for highlighting specific areas
- Creates defined light boundaries
Brightness Levels
Here's something that surprises people - both bulb types can have the same lumen output (brightness measurement). A 650-lumen BR30 and a 650-lumen R30 produce the same amount of total light.
The difference? How that light gets distributed in your space.
The BR30 spreads those 650 lumens across a wider area, making the whole room brighter but with less intensity in any one spot. The R30 concentrates those same lumens into a smaller area, creating brighter spots but leaving other areas dimmer.
Energy Efficiency: Is One Better?
Good news - when comparing LED versions of br30 vs r30 bulbs, energy efficiency is basically the same.
Both typically use:
- 9-12 watts for 650-800 lumens
- Last 15,000-25,000 hours
- Work with most dimmer switches
- Generate less heat than old incandescent bulbs
The energy bill difference comes down to how many bulbs you need. Since BR30s spread light better, you might need fewer of them to light a room properly.
Where Should You Use BR30 Bulbs?
BR30s shine (pun intended) in these situations:
Living Rooms Perfect for creating warm, inviting spaces where you want even lighting throughout. The wide beam eliminates harsh shadows when you're watching TV or reading.
Bedrooms Great for general overhead lighting. You'll get nice, soft illumination without bright spots that hurt your eyes.
Kitchens
Ideal for recessed cans over work areas. The flood pattern lights up countertops and cooking spaces evenly.
Dining Areas Works well over tables when you want gentle, ambient lighting rather than a spotlight effect.
Bathrooms Helps eliminate shadows around mirrors and provides good overall visibility.
Best Uses for R30 Bulbs
R30s work better when you need focused light:
Art Lighting Perfect for highlighting paintings, photos, or decorative items on walls. The narrower beam draws attention exactly where you want it.
Reading Nooks Great for task lighting over chairs or desks where you need concentrated brightness.
High Ceilings In rooms with ceilings over 10 feet, R30s push light down more effectively without spreading too thin.
Track Lighting Works excellently in adjustable track fixtures where you're aiming light at specific spots.
Display Cabinets Ideal for illuminating collectibles or items in glass cases.
Price Comparison and Value
Let's talk money. As of 2024, here's what you'll typically pay:
BR30 LED Bulbs:
- Budget brands: $7-10 each
- Mid-range (Philips, GE): $10-13 each
- Premium (smart bulbs): $15-25 each
R30 LED Bulbs:
- Budget brands: $6-9 each
- Mid-range: $8-12 each
- Premium: $12-20 each
R30s cost slightly less, but they're also harder to find in stores now. Many manufacturers have shifted focus to BR30 production because they're more versatile.
According to lighting industry reports featured on Big Write Hook, BR30 bulbs now outsell R30s by about 4 to 1 in the residential market.
Installation and Compatibility
Both bulb types fit standard medium base (E26) sockets, so swapping them out is easy.
Things to check before buying:
- Measure your recessed can depth (both need at least 5 inches)
- Check if your fixtures are rated for LED bulbs
- Verify dimmer compatibility if you use dimmers
- Consider the trim style on your recessed lights
One issue some people run into: older recessed cans designed for R30 bulbs might have tighter openings. The BR30's bulge could make it stick out slightly more, though this rarely causes actual problems.

Common Mistakes People Make
Over the years, I've seen folks mess up their lighting in predictable ways:
Mistake #1: Buying R30s for general room lighting and wondering why everything looks spotty and uneven.
Mistake #2: Using only BR30s in a room and ending up with flat, boring lighting with no depth or visual interest.
Mistake #3: Not considering beam angle at all and just grabbing whatever's cheapest.
Mistake #4: Mixing BR30 and R30 bulbs in the same room with different color temperatures, creating weird warm and cool zones.
The best approach? Use BR30 for your main lighting and add R30s (or even narrower PAR bulbs) for accent or task lighting if needed.
Color Temperature Considerations
Whether you choose br30 vs r30 bulbs, you'll need to pick a color temperature:
- 2700K (Soft White): Warm, yellowish light like old incandescent bulbs. Great for bedrooms and living rooms.
- 3000K (Warm White): Slightly crisper warm light. Works well in kitchens and bathrooms.
- 4000K (Cool White): Neutral white. Good for garages and workspaces.
- 5000K (Daylight): Bright, bluish white. Best for task lighting and detailed work.
For most homes, stick with 2700K-3000K in main living areas. Your eyes and mood will thank you.
The Future of These Bulb Types
The lighting industry keeps evolving. Smart bulbs are becoming more common in BR30 format, letting you control brightness and color from your phone.
R30 bulbs are slowly fading from the market as manufacturers focus on more versatile options. In five years, they might be hard to find outside specialty lighting stores.
If you're investing in a whole-house lighting upgrade, BR30 LEDs are the safer long-term bet. They'll be around, they'll keep improving, and replacement bulbs will stay easy to find.
Final Verdict: Which One Wins?
For most homeowners, BR30 bulbs are the better choice. They're more versatile, easier to find, and work better for general lighting needs.
R30 bulbs aren't bad - they're just more specialized. If you have specific needs for focused light or accent lighting, they can be perfect. But for everyday use in typical homes, BR30s deliver better results.
My recommendation: Use BR30 LEDs in 2700K-3000K for 90% of your recessed lighting needs. Add narrower beam bulbs only in spots where you specifically want focused light.
Conclusion
Understanding the br30 vs r30 debate doesn't have to be complicated. It really comes down to this: BR30 bulbs spread light wider for general room lighting, while R30 bulbs focus light tighter for specific tasks or accents.
For most rooms in your home - bedrooms, living rooms, kitchens, bathrooms - BR30 bulbs will give you the best results. They create even, comfortable lighting that makes spaces feel welcoming and well-lit.
Save R30 bulbs for those special situations where you need a spotlight effect or you're working with high ceilings that need more focused light projection.
Whatever you choose, stick with LED versions. They'll save you money on electricity, last for years, and give you great light quality. And remember - you can always test a few bulbs before committing to changing every fixture in your house.
Frequently Asked Questions
Can I replace R30 bulbs with BR30 bulbs in the same fixture?
Yes, you can swap them directly. Both use the same E26 base and have the same diameter. The only difference you'll notice is the wider light spread from the BR30. Just make sure the BR30's bulge fits in your fixture housing.
Which is brighter, BR30 or R30?
Neither is inherently brighter. Brightness depends on lumens, not bulb type. You can get a 650-lumen BR30 and a 650-lumen R30 - they produce the same total light. The BR30 just spreads it wider while the R30 concentrates it more.
Are BR30 bulbs more energy efficient than R30?
No, they use about the same energy. A 10-watt LED BR30 and a 10-watt LED R30 consume identical electricity. The efficiency depends on the LED technology, not the bulb shape.
Why are R30 bulbs harder to find in stores now?
Manufacturers have shifted production toward BR30 bulbs because they're more versatile and popular with consumers. The wider beam angle works for more applications, so stores stock what sells best.
Do BR30 bulbs work with dimmer switches?
Most LED BR30 bulbs work with dimmers, but check the packaging. Look for "dimmable" printed on the box. Some cheap LED bulbs don't dim smoothly or flicker, so spending a bit more on quality dimmable bulbs pays off.
How many lumens do I need to replace a 65-watt incandescent?
Look for 650-700 lumens to match a 65-watt incandescent bulb. Most BR30 and R30 LED bulbs in this range use only 9-12 watts, saving you about 80% on energy costs while giving you the same brightness.
