Over time, the light bulb has changed in shape and size to provide lighting that suits your needs. To improve lighting in your space, you need to understand the various types of lightbulbs. This includes both traditional types and those used in business and industrial areas. With this helpful guide, you’ll be one step further to finding the perfect lighting for your space.
Since its debut in 1879, the light bulb has come quite a long way from its standard incandescent state. In a successful attempt to create a more economical form of lighting, Thomas Edison first introduced an incandescent light bulb made with a carbonized filament that was housed in a simple lamp. The Thomas Edison light bulb revolutionized lighting and motivated others to develop a better, brighter version.
Halogen light bulbs were an improved alternative to incandescent bulbs, providing better quality light at the time. With the use of a coiled filament, these light bulbs used halogen gas and iodine to produce a soft warm glow. Experts found that halogen lamps improved slightly, but electrical shortage remained a common issue that required attention.
Fluorescent bulbs lasted longer than older lamps by turning absorbed vapors into white light. Before Light emitting diodes were introduced into the equation, fluorescent lamps reigned supreme in producing useful, energy efficient lighting in most homes and offices.
The use of light-emitting diodes within lightbulbs has brought a new meaning to general lighting. With the use of a semiconductor that transferers electricity into light, LED bulbs can emit light in specific directions and temperatures. Additionally, the diodes use all the energy that they produce, making them more efficient in producing bulb lumens than halogen and incandescent bulbs. With sizes that fit well within most fixtures, LED lights are proven to be the most cost-effective lighting solution that you can purchase today.
Manufacturers will typically use lettering to identify the shape of your LED light bulb. In some cases, additional letters can also mark the specific feature that an LED lightbulb has to distinguish it from its standard counterpart:
Other forms of specialty LED bulbs can be marked with lettering to identify their unique features. For example, “PAR” is marked on bulbs that contain a parabolic aluminized reflector that can make omnidirectional light using reflective surfaces within the bulb. “T” stands for tubular shaped LED lightbulbs that are made to be more energy efficient by reserving current level transmitted to the lightbulb.
The numbers that follow a letter code is used to denote the size in diameter of the LED bulb. The measurement is usually taken across the widest part of the bulb which is usually located around the center of the glass housing. Although the standard form of measurement for LED light bulbs is in millimeters, some manufacturers will display measurements in a fraction of an inch to accommodate for slight variations between products.
Common diameters for most LED light bulbs will usually correspond with their distinct shape to help you choose the most accurate size for your light fixtures:
The right shape and size of LED light bulb can help you meet your specific lighting needs. Whether it is a standard household fixture or commercial lighting system, these common sizes are made to be placed exactly where you need them to produce adequate lighting throughout our space.

Candelabra LED lightbulbs can be used to create an additional element to your decorative light fixtures. With common uses in chandeliers and pendant light fixtures, LED candelabra bulbs can provide visually appealing ambient lighting to formal spaces.
Use Tubular shapes light bulbs in commercial settings that require large amounts of energy efficient lighting. These light bulbs are built to be long lasting, and typically are utilized for task lighting in warehouses, department stores and office buildings.
Most versions of LED lighting comes in various color temperatures to best suit the level of light in your space. The temperature of most LED bulbs is measured in kelvins to help determine the exact tone of lighting that the fixture will display. Temperatures from 1900 to 2700K produces warm white light while 3000 to 5000K produces cool white light.
Color temperatures above 5000K is made to simulate natural light during the day. Along with the placement of your LED bulb types, you should consider the ways in which the color temperature of the lamp will affect your space. Most people typically use warm light in more personal applications while cool light is reserved for business and commercial applications.
LED lightbulbs have various base types that are designed for different types of fixtures. The most common sizes such as E26 and E27 bases are found in standard household fixtures sold in North America.
E12 bases are usually reserved for Candelabra bulb sizes such as B11 or B12. Some decorative fixtures might require an E17 base that accommodates slightly larger bullet shaped bulbs. There are also bases for lamps with specialized housing:
With their unique requirements, different versions of LED bulbs will utilize different base types for certain light fixtures. It is important to identify the required base for your fixture before selecting your LED Bulb:
