ambient lighting applications.
Understanding the "BR" Designation What Does BR Mean? BR stands for Bulged Reflector. These bulbs feature a distinctive dome-shaped lens that diffuses light into a broad, even beam—perfect for ambient and general lighting applications.
The Number Code The number following "BR" indicates the bulb's diameter in eighths of an inch. For example, BR30 means 30/8 inches (3.75 inches), while BR40 means 40/8 inches (5 inches).
BR30: The Focused Floodlight Diameter: 3.75 inches Perfectly sized for standard 4-5 inch recessed cans commonly found in residential and commercial spaces.
Focused Coverage Creates a more concentrated, tighter pool of light ideal for targeted illumination and accent lighting applications.
Brightness: 800-1100 Lumens Provides ample brightness for task lighting and smaller room applications with typical LED wattage of ~9W.
Best Applications Kitchens, bathrooms, offices, and smaller rooms where focused task or accent lighting is required.
BR40: The Wide Illuminator Diameter: 5 inches Designed for larger 6-inch recessed cans and fixtures, providing broader coverage for expansive spaces.
Wide Coverage Delivers a wider, softer spread of light that fills larger areas evenly— perfect for ambient room lighting.
Brightness: 1200-1400 Lumens Higher lumen output with typical LED wattage of ~15W, offering brighter illumination for larger spaces.
Best Applications Living rooms, hallways, open-concept spaces, and rooms with higher ceilings requiring room-filling light.

Brightness & Beam Angle: What to Expect
BR40: Generally Brighter BR40 bulbs typically offer higher lumen output (1200-1400 lm) compared to BR30 bulbs (800-1100 lm), making them noticeably brighter for larger spaces.
Beam Angle Similarities Both BR30 and BR40 bulbs often feature beam angles exceeding 90 degrees. However, the BR40's larger surface area allows for a broader spread of light, covering more area despite similar angles.
