While the function of a light bulb is often simple, it is imperative to have information before choosing a light bulb. However, many options are available that the situation can seem overwhelming. Take your time to find out the best bulb that can match your fixture properly rather than purchasing the correct bulb. Let’s look at things to consider below.
1. Light Bulb Base and Shape
Shape: Light bulbs are often described using their shapes such as spiral, reflector, or globe. They can also be denoted using letters and numbers. The first letter denotes its shape. The second and third denote the diameter and length respectively.
Base: Two main light bulb types are available in the market. The screw and pin base types. For this reason, look at the base hat is easier to connect to the ballast or socket on the source. It is important to choose the correct base with the size combination to ascertain compatibility.
2. Watts and Lumens
The amount of energy that is required to have the bulb light is referred to as the watts. On the other hand, lumens refer to the amount of light produced by the lighted bulb. The light bulb will become brighter if it produces more lumens. Look at the lumens rather than the watts of a bulb when you are selecting a bulb at a local store.
3. Color Rendering Index (CRI)
This describes how the light source makes the object color appear in the eyes of a person. CRI is scaled from 0 to 100 percent to give an indication of the accuracy of a light source. Light sources that are between 80 percent and 90 percent are good for the human eye. Excellent bulbs are those that have a CRI of over 90 percent because they offer accurate colors.
4. Color temperature
Color temperatures are often measured in Kelvin (K). The temperature color of a light bulb is used to describe how the light bulb perceived by the human eye. Bulbs that produce yellow light have about 2700K color temperature. As temperature increases, the yellow color decreases. Temperatures of over 5000K appear blue
For high efficiency, the light bulb voltage should match the fixture voltage. It is, therefore, imperative to be precise with voltage. While high voltage reduces the bulb’s span, low voltage uses more current. In the case of the incandescent bulbs, use low voltage bulbs eve if they emit low light.
Light bulbs can be a sound investment. Over the years, the light bulb prices have been on the rise. Over time, this investment will pay you off. While you might want cheaper bulbs, think about their cost of paying electricity bills. Cheaper is often expensive at the end considering electricity costs. Choose wisely.
