How Do Light Bulbs Work

One of the most popular choices for home lighting these days is the energy-efficient sunlight bulbs. Compared to incandescent bulbs, they have a longer life span, they are cheaper to purchase, and you can even change them out for better color. If you are looking to change your home’s interior decor to match your tastes or to go with the seasons, you should invest in sun-hanging light fixtures. The following paragraphs will explain why you should install these types of lights.

Unlike traditional fluorescent bulbs or incandescent ones, sunlight light bulbs imitate the full spectrum of sunlight, which means they offer the full benefits of natural sunlight to humans. According to several recent studies, the Color Rendering Index (CRI) of sunlight light bulbs is close to 70, which is above the standard. This means that the sun-hanging light fixtures help to reflect more subtle colors naturally, which matches the changing color of the skies. This is why a lot of people prefer using this type of lighting. You may also notice that many interior decorators these days prefer to use sunlight light bulbs over traditional types. This is probably because the light has a warmer effect on the eyes.

Aside from being able to mimic the natural sunlight, they also produce less heat. Traditional light bulbs produce a lot of heat when used, leading to excessive energy consumption and ultimately, higher electricity bills. You might be surprised to know that the cost of electricity has decreased by about thirty percent over the last twenty years. In addition, there is a growing global awareness on saving energy and the environment. This is why more people are switching to energy-efficient devices such as sun-hanging light fixtures. The good thing about using sunlight light bulbs is that they are not toxic to our bodies and they are also long-lasting.

However, using them also means subjecting your eyes to more strain. Even though ultraviolet light is not harmful to our health, but exposure to it can cause eye infections or cataracts if we’re not careful. Luckily, manufacturers have taken steps to make sure that the sunlight light bulbs available in the market today do not produce excessive amounts of ultraviolet rays. They are now classified into three categories based on their ability to let out the required amount of ultraviolet rays.

A Much Ado

The first category of this kind of light is the small amounts of ultraviolet and infrared rays to simulate a sunlight spectrum exactly, even though it has only a very small amount of these UV rays. These are commonly referred to as “white” lights. For this reason, they are best used for general lighting purposes. It is because they produce white color, and they are also less expensive than other types of bulbs.

The second type is the daylight variety, which is commonly called “warm white” lights because they produce colors of yellow-green or pink. Warm white sunlight provides a pleasant background light during daytime and is ideal for illuminating plant beds, sidewalk cracks, fountains, and water features. On the other hand, they are not very good choices for illuminating exterior rooms like living rooms, kitchen, and bedrooms because they don’t cast enough light to create an effect of depth. Warm white bulbs are usually found in street lights. They can be found in a wide variety of wattage depending on the amount of illumination required for a particular area.

The last type of light is the full-spectrum light, which can be classified into two groups – yellow-red and blue-green. This light is made by incandescent bulbs. Incandescent bulbs use energy from the chemical reactions between a hydrogen atom and phosphorus in the phosphor powder. The yellow-red light is produced when electrons move from a redox electrode in the phosphor, while the blue-green light comes from the absorption of ultraviolet radiation from the sun.

Bottom Line

Full-spectrum bulbs produce an extremely good color temperature that mimics sunlight as closely as possible. The color temperature begins to diminish after a while due to the slow introduction of color rays. To obtain the best color temperature, these bulbs should be installed in HPS or high-pressure sodium models.
