What Is a BR30 LED Bulb and What Does BR30 Mean?

A BR30 bulb is a bulged-reflector flood bulb with a nominal 3.75-inch face; the “30” is its diameter in eighths of an inch, not its wattage.

Swap in the wrong one and the trim ring won’t sit flush, or the bulb clips the housing. The letters and numbers on a BR30 LED bulb are a size code borrowed from the incandescent era; once you can read it, fixture shopping stops being guesswork.

What Does the “BR30” Code Stand For?

“BR” means bulged reflector — the rounded, outward-bowing profile that gives these bulbs their wide floodlight spread. The “30” is the nominal diameter in eighths of an inch: 30/8 inches, about 3.75 inches or 95 millimeters.

That rounding matters. Real products land near 3.74 to 3.75 inches, so tight trim clearance can reject a bulb that’s technically “the right size.” Length runs past five inches on common models — the other dimension recessed cans pinch.

BR30 describes shape and size only. It says nothing about brightness, color, wattage, base type, dimming, or smart features.

What Specs Should You Check Before Buying?

Most residential BR30 LEDs use an E26 medium screw base — the standard US household socket — rated 120 V AC at 60 Hz. Beyond that, identical-looking bulbs diverge fast.

Brightness is the spec people skip. Current BR30 LEDs range from roughly 650 to 950 lumens; Philips and GE both list 650-lumen examples, and other models reach 850. Wattage: GE’s 7 W model replaces a 65 W incandescent, Philips lists 7.2 W for a 65 W equivalent, and 8 W and 10–11 W versions exist. Compare lumens, not just the “65 W equivalent” label.

Color temperature splits into warm and cool camps: 2700 K and 3000 K for warm white, 4000 K neutral, 5000 K daylight-like. Color rendering varies — Philips lists CRI 90, other examples CRI 80+.

Rated life spans 11,000 hours on some models, 15,000 on Philips, up to 25,000 on others.

BR30 vs. PAR30

Both are reflector formats with the same 3.75-inch nominal face, but construction differs. A PAR30 uses a precise, faceted or lensed reflector that throws a tighter, controlled beam; a BR30’s bulged reflector spreads light more softly and broadly, suiting general downlighting over accent work.

Beam angle proves shape alone tells you nothing. One BR30 has been listed at 110°, while a specific model lists 40° — same code, wildly different spread. Check the stated beam angle and fixture clearance before assuming interchangeability.

Where Do BR30 LEDs Belong?

They’re wide-beam floodlights built for recessed downlights, track fixtures, kitchens, basements, and general lighting. Where buyers trip:

• Damp and outdoor ratings: Some models are UL listed for damp locations; another is marked indoor use only. A UL listing alone doesn’t permit every installation condition.
• Dimming isn’t guaranteed: Dimming is a product feature, not a BR30 promise. Confirm the bulb is marked dimmable and check dimmer compatibility; mismatches cause flicker, a narrow range, or failure.
• Base and voltage: Confirm the fixture takes an E26 medium base and a bulb about 3.75 inches wide, and match required voltage. Cited US models are generally 120 V AC.

Before installing, cut power at the switch, let a recently used bulb cool, and screw the new one in without overtightening. If you’ve confirmed your fixture specs and want a shorter list to compare, our tested BR30 LED bulbs roundup puts current options side by side. For manufacturer numbers on a specific dimmable model, GE’s BR30 floodlight product page lists wattage, lumen, and color temperature specs directly.

Common Questions

Is a BR30 brighter than a standard LED bulb?

Not automatically. Brightness comes from lumens, and current BR30 LEDs range from roughly 650 to 950 lumens. A 650-lumen BR30 is less bright than a 900-lumen bulb of a different shape. Compare lumens, not shape code.

Can I use a BR30 in a recessed can rated for a PAR30?

Often yes, since both share a nominal 3.75-inch face, but PAR30 is more focused and BR30 more spread. Check housing clearance and desired beam angle before swapping.

Do all BR30 LED bulbs work with a dimmer switch?

No. Dimming is model-specific. Even dimmable versions can flicker or cut out if they don’t match your dimmer. Verify both the dimmable rating and the manufacturer’s dimmer compatibility guidance.
