What is BR30 Bulb?

A BR30 bulb is a type of reflector bulb commonly used in residential and commercial lighting fixtures. The “BR” stands for bulged reflector, which indicates the shape of the bulb — a wide, bulged base that narrows to a rounded top.

The “30” in BR30 denotes the diameter of the bulb at its widest point, which is 30 eighths of an inch, or 3.75 inches. This bulb shape is designed to direct light in a broad pattern, making it ideal for floodlighting and general area lighting.

Design and Features

In this section, you’ll gain insight into the specific design elements and notable features of BR30 bulbs that distinguish them from other light bulb options.

Physical Dimensions

Your BR30 bulb typically measures 3.75 inches in diameter and has a length of approximately 5.37 inches. This standardized sizing allows for consistency across different brands and fixtures designed to accommodate them.

Bulb Shape and Appearance

The BR30 bulb is recognizable by its distinctive bulged reflector shape. BR stands for Bulged Reflector, indicating the shape designed to direct light. The “30” denotes the size of the bulb’s diameter in eighths of an inch. Therefore, a BR30 bulb’s face measures nearly 3.75 inches wide.

Beam Angle

A key feature of the BR30 bulb is its beam angle, which is often between 110° and 120°. This angle allows for wide dispersion of light, providing a uniform light spread ideal for general lighting purposes. The specific beam angle influences how concentrated or diffused the light output will be in your space.

Lighting Specifications

The lighting specifications of a BR30 bulb determine its performance and suitability for different lighting needs. Understanding these specifics will help you choose the right bulb for your space.

Lumens and Brightness

Lumens measure the amount of light emitted by a bulb. A higher lumen count means a brighter light. Typically, a BR30 bulb ranges from 650 to over 1,000 lumens.

Color Temperature

Color Temperature is gauged in Kelvins (K) and describes the hue of the light. BR30 bulbs can vary from warm yellow tones around 2,700K providing a cozy atmosphere, to cool blue tones of 5,000K or higher for a more alerting effect.

Energy Efficiency

Energy Efficiency is crucial for sustainable usage and cost reduction over time. Modern BR30 LEDs are more efficient than traditional incandescent bulbs, consuming anywhere from 8 to 15 watts while offering the same light output as a 65-watt incandescent bulb.


Dimmability allows you to adjust the light intensity of your bulb. Many BR30 LED bulbs offer full dimming capabilities, but confirm compatibility with your dimmer switch to ensure proper function.


BR30 bulbs are versatile lighting solutions tailored for broad illumination in both residential and commercial settings. They provide focused lighting with a broad-beam angle, suitable for an array of applications.

Residential Use

Your home can benefit from the warm, incandescent-like glow of BR30 LED bulbs, making them perfect for living rooms, kitchens, and bedrooms. Specifically:

  • Living Rooms: Ideal for recessed fixtures and track lighting to create a welcoming ambience.
  • Kitchens: Provide bright, wide-angle illumination over countertops and islands.
  • Bedrooms: Soft light for a relaxed environment, often used in bedside or overhead fixtures.

Commercial Use

For your business, the BR30 bulb’s efficiency and durability make it a smart choice. Key applications include:

  • Offices and Conference Rooms: Improve concentration and reduce eye strain with consistent, even lighting.
  • Retail Spaces: Highlight merchandise without the harshness of spotlighting.
  • Hospitality Settings: Offer guests comfortable lighting in lobbies and dining areas.

Installation and Compatibility

Before you choose a BR30 bulb, ensure your fixtures and sockets are compatible. The installation process is usually straightforward, but compatibility is key to proper functioning.

Socket Type

E26 is the standard socket type for BR30 bulbs in the United States. When installing:

  1. Turn off the power to the socket at the switch or circuit breaker.
  2. Insert the bulb by aligning its base with the socket.
  3. Turn the bulb clockwise until it is secure.

Do not force the bulb into the socket; it should fit snugly without excessive pressure.

Fixture Compatibility

BR30 bulbs are designed for indoor or outdoor fixtures that accommodate the bulkier size of reflector bulbs. Check for:

  • Recessed lighting cans: Verify they are deep enough to house the BR30 bulb.
  • Track lighting: Ensure the track heads are meant for BR30 size bulbs.
  • Outdoor fixtures: Confirm they are weatherproof if using BR30 LED bulbs outside.

Compatibility with dimmers varies by bulb brand and model. Look for the dimmable label on the bulb’s packaging if this feature is required.

Considerations Before Purchase

When considering the purchase of a BR30 bulb, you should assess factors such as its lifespan, cost, and the brand’s reputation to ensure you’re making a sound investment.

Lifespan and Reliability

Lifespan: On average, a BR30 LED bulb has a lifespan of 25,000 to 30,000 hours. Compare this to traditional incandescent bulbs, which may only last between 1,000 to 2,000 hours.

Reliability: Look for bulbs that come with a warranty or guarantee, as this can be a good indicator of the manufacturer’s confidence in their product’s durability and performance.

Cost Factor

Initial Expense: While BR30 LED bulbs are generally more expensive upfront compared to traditional bulbs, they are more cost-effective in the long run due to their lower energy consumption and longer lifespan.

Energy Savings: An energy-efficient BR30 bulb can use up to 75% less energy than incandescent bulbs, which translates into substantial savings on your electricity bill over time.

Brand Variations

Quality: Different brands offer varying levels of quality in terms of color accuracy (CRI), dimming capabilities, and light output (lumens).

Compatibility: Ensure the bulb you choose is compatible with your existing light fixtures and dimmer switches to avoid additional expenses or the inconvenience of returns and exchanges.

Alternatives to BR30 Bulbs

If you’re looking for alternatives to BR30 bulbs, you have several options to consider, each with its own features and advantages. Below are common alternatives:

PAR30 Bulbs

  • Similar in size to BR30 bulbs
  • More focused, narrow beam of light
  • Ideal for track lighting or spotlighting

A19 Bulbs

  • Standard bulb shape with a wider base
  • Used in general lighting applications
  • Not as directional as BR30 bulbs

LED Panels

  • Flat, rectangular lighting solutions
  • Provide diffused light that’s easy on the eyes
  • Excellent for office spaces or modern interiors

Smart Bulbs

  • Offer features like dimming, color change, and connectivity
  • Controlled via smartphone apps or voice assistants
  • Save energy with programmable settings and features

Here’s a quick comparison:

Bulb Type Beam Angle Best For Smart Features
PAR30 Narrow Spot & Track Lighting Some options
A19 Wide General Lighting Many options
LED Panels Diffused Office & Modern Interiors Limited options
Smart Bulbs Adjustable Customizable Settings Extensive options

When replacing BR30 bulbs, note the differences in beam angles and the type of lighting you require. For example, if you need directed light for artwork or accent pieces, PAR30 bulbs might be your best bet. Conversely, for a soft light to fill a room, an A19 might be more appropriate. And for energy savings and customization, smart bulbs are the go-to choice. Always ensure compatibility with your current fixtures and desired ambiance.
