Types of Light Bulbs

The history of lighting it is fascinating. Among the first means of lighting we mention fire, torches, candles and candles.
Electric lighting it gained momentum in the 16-17 centuries, and since then the trend has been an upward one in terms of the advantages brought to users.
 
TYPES OF BULBS
 
In the beginning there were incandescent bulbs, then halogen bulbs, after which the big leap was made economic bulbs compact, also known as CFL bulbs. LED technology has reached its peak in terms of artificial light, through efficiency, safety and maximum saving capacity.
 
  • Incandescent bulbs 
 
Incandescent bulbs are those bulbs that we call "ordinary bulbs" or "classic light bulbs”.
 
Advantages
 
In their case, unfortunately, the advantages are not very many. Some still buy them because they fall into the category of cheap light bulbs. Others have their nostalgia for the simple fact that the color temperature of the light that I emit is a very pleasant one.


 
Disadvantages
 
Incandescent bulbs are not the most efficient the light source, because they have a very high energy consumption. To produce light, they must heat up. More precisely, the metal filament is heated by the electric current, and it emits light. A very small percentage (8%) of the energy consumed is transformed into light. One classic light bulb it can be seen, from this point of view, as a mini-radiator. 
 
Besides the fact that they waste energy, incandescent bulbs have a short lifespan. Even if you pay a little at the time of purchase, they become very expensive over time. They have a durability of 1000-2000 hours and are totally uneconomical in the long term - an aspect that you must think about very carefully before deciding on these types of bulbs.
 
  • Halogen bulbs
 
Halogen bulbs are also incandescent bulbs, but they also contain a gas with halogen elements.
 
Advantages 
 
They also illuminate by heating the incandescent filament, but they have a longer lifespan than classic bulbs, and color temperature is higher (2500K). They have one luminous flux of about 20 lumens/watt and emit white light, of a superior quality to ordinary light bulbs.
 
The halogen bulb can be a dimmable bulb, that is, in some models you can adjust light intensity. If you want one cheap lighting, halogen bulbs are good, but they are not a profitable investment.
 
Disadvantages
 
Even if they have a better energy efficiency than ordinary bulbs, they are not the best choice in this regard. In reality, a halogen bulb consumes 2-4 times more than an incandescent bulb economic bulb compact or one led bulb. And in terms of lifespan, it leaves much to be desired. It lasts on average 2000-3000 hours.
 
Halogen bulbs are suitable for spaces less frequented during the day, such as bathrooms, cellars, attics, cellars, where you don't have to turn on the light very often.
They are also an optimal choice for lamps.
 
  • Compact economic bulbs - fluorescent bulbs
 
Compact economical bulbs (CFL) work on the same principle as fluorescent bulbs. They contain mercury vapor and produce ultraviolet rays. 
 
Advantages
 
Classic economic bulbs have the shape of a spiral, a tube or a rod. They are a cheap option for those who are looking economic bulbs. It consumes 75% less energy compared to incandescent bulbs and it is possible to find dimmable versions. 
 
Disadvantages
 
Energy saving CFL bulbs are larger than incandescent bulbs. They light up gradually and you have to wait a while until they reach their maximum lighting capacity. They are not suitable for rooms where you turn the light on and off often. These bulbs allow between 100,000 - 600,000 ignitions and last around 8,000 - 15,000 hours, much longer than halogen bulbs. 
 
  • LED bulbs
 
LED lighting is present in more and more homes, industrial and commercial units. Installation of economic leds in a home or in a company means a significant reduction in energy consumption and electricity costs.
 
What does LED mean?? This abbreviation comes from "light emitting diode" and translates as "light emitting diodes". The LEDs it generates light through a phenomenon called "electroluminescence", when the electric current passes through a semi-conducting material and emits a visible light. 
 
LED technology is not from yesterday, from today. The first LED was developed in the 60s. Even from that time, the advantages of their use in terms of energy efficiency and durability were known. The second generation of LEDs appeared in the 90s, also when it started to be used in public lighting. 
The companies sought to replace the fluorescent bulbs with LEDs at the outdoor advertising panels. The currently available LEDs are part of the 3rd generation.
 
Advantages
 
Some important features of these types of led bulbs: 
  • increased resistance
  • considerable lifespan
  • maximum effectiveness
  • increased energy efficiency
  • low maintenance costs
  • financial savings
  • less residual light
  • better environmental performance
  • immediate maximum ignition
  • resistance to damage factors, falls or other shocks
  • they do not contain particles of mercury, lead or other toxic compounds
 
Disadvantages
 
If you decide to buy led bulbs for the home, you have to expect higher prices than other types of bulbs.
But this disadvantage will turn into a long-term advantage, because after you cover the purchase costs, you will have to pay less from the next invoice.
 
Another minus for LED bulbs is the fact that they spread the light in one direction. To avoid this, opt for lighting fixtures with more LEDs.
 
PARALLEL BETWEEN TYPES OF BULBS 
 
If you switch from classic bulbs to economic lighting fixtures you only have to win. LED bulbs are considered the most economical bulbs. It is worth changing the old bulbs with economic leds because you save energy and money. The investment pays for itself in a relatively short time (1 year at 3 hours of consumption/day), and you can enjoy an optimally lit house with considerably lower bills.
 
More and more people are using modern LED lighting fixtures for interior and exterior. These light bulbs with low energy consumption they are extremely convenient in that they emit an increased amount of light, while the electricity consumption is lower than with standard bulbs. Replacing all lighting sources in your home or office with LEDs will bring you a 60-90% improvement in energy efficiency. 
 
LED bulb equivalent to incandescent bulb in terms of power consumption is clearly in favor of the first category. LED bulbs consume almost 7 times less energy. 
An incandescent bulb can last around 1,000 hours. An LED bulb lasts 50,000 hours and can reach up to 100,000 hours. 
 
LED light it does not have to be changed annually. It has a lifespan of 6-12 years, that is 40 times longer than incandescent bulbs and 2-4 times longer than fluorescent bulbs.
 
LED bulbs operate at maximum capacity during winter or at low temperatures, compared to fluorescent bulbs, where the light intensity decreases in these conditions. For these reasons, LEDs are a smart choice for freezers and other cold spaces.
 
From the category of powerful led bulbs are part of the types of led 12W and 15W led bulbs. They have as much power as a 90W or 120W incandescent bulb.
 
TYPES OF SOCKETS 
 
When you choose one light fixture, you have to choose one socket correspondingly. The socket is the support on which the bulb filament is placed. The good news is that some LED bulbs they are designed to fit the sockets used for classic light bulbs.
 
Sockets with thread:
