Edison bulbs

One of the world's greatest inventions is the light bulb, a small object that has had a huge impact on mankind. The most important change brought about by him is represented by artificial light, the light without which today's society could not function at its best. They all had a beginning, and so did this small product, over time it has continuously evolved ensuring our visual comfort, both day and night, in our homes, at work and on the street.

The first creation of the light bulb was made by Joseph Wilson Swan, but it had a defect in the internal vacuum, here intervenes another genius named Thomas Edison who improved Swan's idea, creating a filament for the light bulb, succeeding for the first time in creating a light bulb that worked for an average of 40 hours. Edison continued to improve his creation until they worked for up to 600 hours and began to be marketed. Swan and Edison had a conflict over the creation of the light bulb, but in the end they allied and established the Edison-Swan United company, the largest light bulb manufacturing company. 

Over time this product has evolved, giving us today the opportunity to choose from a wide range of products. We will list below bulb types and their characteristics so that we can get a better idea of them and know what is more beneficial to purchase.

Incandescent bulb filament is the earliest known light bulb and is the completed creation of Thomas Edison. It works by heating a metal filament until it reaches the incandescence point. They are also the most accessible and widespread bulbs, they have a simple system of use, they can be used both for interior lighting and external and can work with both direct and alternating current. The main disadvantage is the high consumption of 60W-100W, considering that the efficiency and lifetime are low, operating on average 1200 hours. 

Halogen bulbs are similar in structure to incandescent bulbs, the difference being the presence of halogen in the bulb. They last longer and the intensity of light produced is higher than a classic light bulbs, also their size is smaller and can be used for several purposes. As a major disadvantage is the presence of halogen, which is a dangerous element for people, as well as the slightly higher cost than that of classic bulbs.

LED bulbs have started to become much more popular lately, they convert electricity only to certain parameters, necessary for operation. They can be used for interior lighting and exterior, they have a long life, 50,000 hours, being designed with superior quality materials and have a low energy consumption, 3W -20W, and a faster lighting efficiency than in the case of classic bulbs. As a disadvantage we have the high price of the product and the fact that it emits a directional light.

Economical light bulbs they have a structure similar to the classic ones, they can replace them. They have a longer lifespan, 8000 hours, and a lower power consumption, 13W - 55W. Disadvantages are the high price of the products, the possibility of containing materials such as mercury, and the need for other additional circuits for proper operation. 

Thus LED bulbs takes the first place with low energy consumption, quality materials and a long life, followed by economic bulbs and incandescent ones, halogen bulbs are not recommended for our daily use because of the halogen content.

Light bulbs are the method by which we bring light into our homes, but lighting fixtures they are what give us the opportunity to put our personal stamp on our homes and offices. In the range Alessandro Design find a multitude of such fixtures, modern, vintage, classic that will bring a splash of color to your everyday life.

Apart from the aesthetic beauty of these products, they also come with the possibility of having a single light source and up to 6 sources or 12 light sources, depending on your needs. They are also present the chandeliers which can be controlled by remote control, but also those with classic switch, are able to emit warm light, cold or neutral, on different levels of intensity to be able to ensure visual comfort regardless of the time of day and the season.
