The baseball season has started, NASCAR has revved up for the summer and football is right around the corner. All these sports, at one time, could only be enjoyed during the day. Mr. Electric®, a company committed to powering tomorrow, looked at how electricity and lights changed sports forever.

On the night of September 28, 1892, the game of football was changed forever when Wyoming Seminary played Mansfield State Normal School in the first-ever night game. The game lasted 20 minutes, consisted of a total of ten plays and ended with neither team scoring. The game ended early due to several players getting hurt by running into light poles caused by the insufficient lighting system. The first night game West of the Mississippi was played in Kansas by the now, Wichita State, and Sterling College in 1905. With upgraded lighting systems many games are now played at night. On September 28, 1992, Monday Night Football celebrated “100 years under the lights” in a game featuring the Kansas City Chiefs and St. Louis Rams.

Baseball was behind football when it came to playing at night. Though teams had played at night since the 1880s, many teams did not make it common practice until many years later. The first ever Major League Baseball game to be played at night took place on May 24, 1935, in Cincinnati when the Cincinnati Reds played the Philadelphia Phillies. The Chicago Cubs were the last Major League Baseball team to finally host a game at night in their home stadium of Wrigley Field. The game took place on August 9, 1988. The World Series had its first night game in 1977. Now, every Major League Baseball stadium has lights and night games are a common occurrence.

Bristol Motor Speedway was the first NASCAR track to have lights installed for night races in 1992. In order for night racing to take place in NASCAR lights had to be designed that would not blind the drivers as they raced around the track. Bristol was one of the first tracks to have night racing. Since 1992, many tracks have added lights for night racing. Some of the most popular night races take place at Kansas City, Richmond, Charlotte and Bristol Speedways. None of these sports would be where they are today without the advent of electricity and intelligently designed lighting systems.

Super Bright LEDs employs skilled engineers and experts to test LED lights before they’re sold. Our in-house test lab is stocked with numerous pieces of equipment that provide important specifications about each product, such as brightness, color temperature, and operating temperature. Testing methods include the use of integrating spheres, spectrometers, Forward-Looking Infrared (FLIR) cameras, and an environmental chamber. In addition to this equipment, our technicians perform burn-in tests and durability tests that can last anywhere from two weeks to several months.

Our state-of-the-art environmental testing chamber utilizes a 30-cubic-foot enclosure to reproduce the full ranges of temperature and relative humidity found within commercial and industrial LED lighting applications. Data collection (photometric & electrical) occurs while a device-under-test cycles through specified environmental extremes. Chamber temperature ranges from negative 35° C (negative 31° F)  to 200° C (392° F), and humidity ranges from 10 to 95 percent.

To ensure that our products will perform under normal and extreme conditions—and to have a little fun—our technicians put them through a round of applicable tests. A selection of LED lights is time tested in the environment that each product is designed for. For example, waterproof boat lights are submerged in water, and weather-resistant landscape lights are installed outside. Depending on the type of product and its impact/weather rating, our technicians might drop, run over, freeze, burn, or even saw it in half to test the product’s durability.

Understanding common household light bulb shapes, sizes, and styles is important whether you’re converting outdated incandescent fixtures into energy-efficient ones or using LED bulbs for new-construction applications. Every light bulb has identifying characteristics that are represented by a letter or series of letters and a number; these are known as light bulb codes. The letter or letters in a bulb code indicate either shape or special features such as reflector type. Numbers in a bulb code indicate size in millimeters or eighths of an inch. These codes will tell you if a bulb will fit in your fixture and if it’s the right shape.

For every light fixture or application, there’s going to be a specific bulb or light bulb shape that will fit best and provide the right type of light. If you understand bulb codes, it’s easy to look at a light fixture and know right away what kind of bulb you’ll need.

Let’s talk about light bulb groups, their bulb codes, and what applications those bulbs are typically used for.

Standard/arbitrary (A) bulbs are the most widely used and thought of when it comes to household lighting. These bulbs work well for a variety of applications, such as ceiling lights, lamps, vanity lights, kitchen lights, closet lights, porch light fixtures, and so many more.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

A15 bulb: 15/8 = 1-7/8″ diameter

A19 bulb: 19/8 = 2-3/8″ diameter

A21 bulb: 21/8 = 2-5/8″ diameter

A25 bulb: 25/8 = 3-1/8″ diameter

Most common base types:

Globe (G) bulbs have a full, round shape and are available in various sizes. They can be used for many applications throughout the home, such as foyer lights, kitchen lights, chandeliers, and ornamental fixtures. The most common type is the large G30 bulb, which is used in bathroom and makeup vanities.

Depending on the bulb, numbers in each code can refer to the bulb’s diameter in one-eighths of an inch or in millimeters.

G11 bulb: 11/8 = 1-3/8″ diameter

G14 bulb: 14/8 = 1-3/4″ diameter

G16/G50: 16/8 = 2″ diameter

G60: 60 millimeters = 2-3/8″ diameter

G25/G80: 80 millimeters = 3-9/64″ diameter

G30: 30/8 = 3-3/4″ diameter

Most common base types:

All of the bulbs in these groups resemble the shape of a candle flame and are often referred to as candle bulbs. Conical (C) bulbs are shaped like a cone. Conical angular (CA) bulbs are shaped like a cone but have a bent tip. Blunt-tip (B) bulbs are very similar to C-type bulbs but have more of a torpedo or bullet shape. These bulbs can be used in chandeliers, wall sconces, pendant lights, night lights, decorative light strands, holiday light strands, and other decorative home lighting applications.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

B10 bulb: 10/8 = 1-1/4″ diameter

CA10 bulb: 10/8 = 1-1/4″ diameter

C7 bulb: 7/8 = 7/8″ diameter

C9 bulb: 9/8 = 1-1/8″ diameter

C15 bulb: 15/8 = 1-7/8″ diameter

Most common base types:

BR stands for bulged reflector. Traditionally, the inside surface of an incandescent BR bulb is covered in reflector material that is used to gather and cast a wide beam of light away from the bulb. LED BR bulbs don’t require the reflector material. These bulbs can have a frosted, clear, or patterned dome-shaped lens that diffuses light and provides a gradual fade into nonilluminated areas. BR bulbs also produce less shadows when compared to PAR bulbs. They’re a bit longer than PAR bulbs and tend to protrude from light housings but are used in similar applications, such as track lights, recessed lights, display lights, or can lights.

BR20 bulbs are often referred to as R20 but have the same characteristics of other BR bulb types. The R stands for reflector.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

BR20/R20 bulb: 20/8 = 2-1/2″ diameter

BR30 bulb: 30/8 = 3-3/4″ diameter

BR40 bulb: 40/8 = 5″ diameter

Most common base type:

Multifaceted reflector (MR) bulbs are small in size with a reflective, faceted interior. The facets create a concentrated beam of light that can be displayed in a narrow spot or wide flood beam pattern. Because of the directional light they provide, MR LED bulbs don’t require the facets but often still have them. These bulbs are available in a variety of colors and can be used for many applications, including track lighting, recessed lighting, desk lights, and display case lighting. Many MR bulbs operate on low-voltage wiring systems, which makes them great for outdoor and landscape applications such as driveway lights, path lights, gazebo lights, paver lights, and malibu lights that have weatherproof housings.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

MR11 bulb: 11/8 = 1-3/8″ diameter

MR16 bulb: 16/8 = 2″ diameter

Most common base types:

Tubular (T) bulbs come in a variety of lengths and widths. Depending on their size, these bulbs can be used in applications ranging from chandeliers, wall sconces, and pendant lights to basement and garage troffer light fixtures.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

T7 bulb: 7/8 = 7/8″ diameter

T8 bulb: 8/8 = 1″ diameter

T10 bulb: 10/8 = 1-1/4″ diameter

T14 bulb: 14/8 = 1-3/4″ diameter

Most common base types:
