Primary Characteristics of a Light Bulb

The following are all things you must know before purchasing a bulb to ensure that the bulb you buy will fit your fixture perfectly.

Type of cap or base

The type of bulb base refers to the part of the bulb that is attached to the fixture. Different types of bulb bases come in different shapes and sizes, and you will need to choose the appropriate bulb based on the type of base of the fixture.

The following are common bulb base types - the letter represents the name of the base, while the number indicates the diameter of the base (in millimeters). For example, an E27 bulb is an Edison screw-in bulb with a diameter of 27 millimeters.

  • E27: Also known as a large screw base, this is one of the most common bulb base types, with a diameter of 27 millimeters, and is suitable for most domestic and commercial lamps.
  • E14: also known as small screw base, 14 mm in diameter, suitable for some small lamps such as table lamps and wall lamps.
  • GU10: is a double pin base, suitable for some spotlights and downlights and other lamps.
  • B22: also known as large lamp base, suitable for some old-style lamps and lanterns.
  • B15: also known as small lamp base, suitable for some small lamps, such as table lamps, wall lamps and so on.
  • MR16: It is a kind of double pin base, suitable for some lamps and lanterns such as spotlights and downlights.

Note: Different types of bulb bases are not interchangeable, you need to choose the corresponding bulb according to the type of base of the lamp. When purchasing a bulb, you need to check the base type on the bulb package to ensure that you choose the correct bulb.

Voltage

Voltage is an important concept in electrical power systems, which represents the potential difference or potential energy difference of the current flowing in a circuit.

We can also understand it as the pressure of current flowing into an electronic device. It is measured in volts. The standard voltage in U.S. homes is 120 volts, and this voltage also applies to electrical equipment and light fixtures in most commercial buildings, which is why most indoor lighting requires 110-120 volt light bulbs.

For outdoor electricity, the standard voltage in the United States is usually 120 volts or 240 volts AC. These voltages are suitable for outdoor lighting, power tools, pool equipment, and other outdoor equipment. It is important to note that the voltage requirements for outdoor electric equipment may vary depending on the type and power of the equipment, so when purchasing and using outdoor electric equipment, you should carefully review the voltage requirements of the equipment and make sure that it is compatible with the voltage of your local electrical system.

You can find voltage information labeled on the bulb itself or printed on its packaging. Be sure to purchase a bulb that matches the voltage supplied to the fixture. Using a bulb with the wrong voltage will make it impossible to turn the light on, and it may even damage the bulb and the fixture.

Bulb Wattage

Light bulb wattage is a unit of measurement of the power of a light bulb and indicates the amount of energy consumed by the light bulb per second. The higher the wattage, the more energy the bulb uses per second and the brighter the light emitted. For example, a 60-watt bulb uses 60 joules of energy per second and emits a brighter light than a 40-watt bulb.

Wattage and brightness of the relationship: light bulb wattage and the brightness of the light bulb has a certain relationship, but is not absolute. Different types of bulbs may have different brightness for the same wattage. For example, LED bulbs have a relatively low wattage, but can be brighter than traditional incandescent bulbs.

  • Wattage vs. energy efficiency: Bulb wattage is also related to energy efficiency. Lower wattage bulbs are usually more energy efficient because they use less energy per second for the same amount of brightness.

When purchasing bulbs, you need to carefully consider the requirements of the fixture and choose the right bulb to enhance the lighting experience.

Brightness is now measured in units of luminous flux called lumens (lms). Lumens represent the amount of light emitted by a light bulb, regardless of the wattage used. The higher the lumens, the more light the bulb produces. It is a more accurate indicator of brightness.

We recommend using LED bulbs for the highest light output or lumens per watt. LEDs emit 70-90 lumens per watt, while incandescent bulbs produce only 10 lumens per watt. Wattage is also an important consideration in terms of power consumption. The higher the wattage of the bulb, the higher the electricity bill. Wattage is also important, and when choosing a light bulb, the right wattage should be selected based on the brightness and energy efficiency needed. If you need a brighter light, choose a bulb with a higher wattage; if you need a more energy efficient bulb, choose a bulb with a lower wattage.

When purchasing light bulbs, know the maximum wattage rating of the fixture or use the wattage of your old bulbs as a guide. To be on the safe side, choose a bulb with a lower wattage and higher lumens. Never use a higher wattage bulb as it may damage your fixture or even become a potential fire hazard.

Other parameters to consider when choosing a bulb

Bulb Illumination

Bulb illuminance is the intensity of light hitting a specific area or surface, and can also be understood as the brightness or light intensity of the light. It is used to measure the distribution and intensity of light in a given area, and is usually measured in lux. 1 lux is equal to 1 lumen of light intensity received per square meter.

Bulb illuminance indicates the distribution and intensity of light in a given area. For example, a room with an illuminance of 500 lux means that a total of 500 lumens of light are received on each square meter in the room.

Illuminance has a relationship with brightness, but it is not absolute. Brightness refers to the luminous intensity of the light source itself, while illuminance refers to the intensity of light in a particular area. The same brightness, different distances from the source of the region may have different illuminance.

Epazo Toi recommends 300-400 lumens per square meter of space. If you have a 10 square meter office, you will need approximately 3,000-4,000 lumens for optimal illumination.

color temperature

The color temperature of a light bulb refers to the color characteristics of light, usually expressed in Kelvin (K) as the unit. Color temperature describes the warm or cool characteristics of light and is very important for creating different lighting atmospheres and adapting to different environmental needs. The higher the Kelvin, the whiter or cooler the light.

According to different color temperatures, light bulbs can be divided into the following types:

  •     - Warm White: The color temperature is between 2000K and 3000K, showing a warmer yellow tone, similar to the light of traditional incandescent lamps.
  •     - Natural White: The color temperature is between 3500K and 4500K, between warm white and cool white, showing a more neutral white tone.
  •     - Cool White: The color temperature is between 5000K and 6500K, showing a cooler cyan tone, similar to the light of a fluorescent lamp.
Chandeliers are a very popular choice when we want to add some lighting and decorative effects to a room. Chandeliers are usually installed in the center of the room and can provide light and ambience to the entire room. Chandeliers come in a wide variety of types and styles and can be chosen according to different needs and decorative styles. For example, modern style chandeliers usually feature minimalist designs and materials, while traditional style chandeliers may feature more sophisticated designs and materials such as crystal and glass. When choosing a chandelier, you need to consider the size and height of the room, as well as the size and shape of the chandelier. The brightness of the chandelier and the type of bulb also need to be considered to ensure that it provides enough light and is energy efficient.

Color temperature selection: Choosing the appropriate light bulb color temperature depends on the desired lighting effect and ambient atmosphere. Generally speaking:

  • Warm white is suitable for places where a warm and comfortable atmosphere needs to be created, such as bedrooms, living rooms, etc.
  • Natural white is suitable for places that require neutral and natural light, such as offices, commercial spaces, etc.
  • Cool white is suitable for places that require bright and clear light, such as kitchens, hospitals, etc.

Color Rendering Index (CRI)

Color rendering index is an indicator used to describe the ability of a light source to restore the color of an object. It is determined by comparing the color difference between an object illuminated by a light source and an object illuminated by a standard light source. The color rendering index has no unit and is usually expressed as a numerical value between 0 and 100. The higher the value, the better the light source's ability to restore the color of the object.

The color rendering index is affected by factors such as the color temperature of the light source and the spectral distribution of the light source. Generally speaking, a light source with a color rendering index above 80 can restore the true color of an object, while a light source with a color rendering index below 60 will cause obvious changes in the color of the object. Artificial light sources with low CRI can cause color changes and distortions, which can lead to visual fatigue. For best results, look for bulbs with a higher color rendering index. For indoor lighting, a CRI of 80 and above is recommended, while for outdoor lighting, a CRI of at least 65 is recommended.
