What are LED bulbs ? What are its advantages?

LED bulbs are the stars of the moment when it comes to energy efficiency, lifespan, and environmental impact. However, although most Spaniards already have at least one of them at home, few know how to choose the most suitable for their consumption and needs.

What are LED lights?


As you already know, since 2012, the traditional incandescent lamp has ceased to exist (at least for sale) and cannot be found on the market.

Although competition for which brand will top the big list, halogen and energy efficiency lights will be the subject of another article.

Today, our goal is to introduce you to the LEDs, the ones everyone is talking about. Do you want to know what they are?

LED bulbs Shining


The first thing is to know what LED lighting is. LEDs are light-emitting diodes, that is, small sources of light that will illuminate with the movement of electrodes through a material that will be a semiconductor.

While the first was developed in 1927, it was not until the 1960s that it began to be used in industry.

Initially, these colors could have been built in red, green, or yellow with low light intensity, but today they are so advanced that they can provide enough white light to illuminate a room.

How do LED bulbs work?


Its process consists mainly of passing an electron through a conduction band where, when it loses energy, it transforms into a photon of random amplitude, direction and phase.

What are the advantages of using LED bulbs?
Among the main advantages of LED lamps you can find:

Energy saving of approx 80%.
Longer life span (approx. 50,000 hours).
Less environmental impact.
It does not contain mercury.
Lower maintenance costs.
High energy efficiency.
It does not emit infrared or ultraviolet rays.
Directional light.
The ability to choose the color tone.
Instant on 100% density.
They are operated at low temperatures (below 40 ° C).
They work at low voltage in direct current.
High efficiency in cold environments.
Greater freedom in designing luminaires.


What are the disadvantages of using LED bulbs?


Since nothing is perfect in life, these types of lamps also have some disadvantages. Among the most important are:

They do not have a standard format
Weak regulations and legislation
The efficiency of the valve depends a lot on the operating temperature.

What kinds of LED bulbs are there?


Currently, the market offers various types of LED lamps. You should know that the types of LED lamps will differ according to their characteristics and characteristics, which will depend on:

The number of bulbs they have (between 3 and 20).
LED quality.
The amount of active substances you have.
The number of watts it consumes.
Light opening angle.
Light temperature.


How to choose a suitable LED bulb?

When you go shopping, choosing an LED bulb will depend exclusively on the use you want and where it is located. Therefore, both of the features we mentioned above will help you choose. If you don’t want to get lost among the many concepts we recommend you to follow these buying guidelines:

Step 1: How much do you want to save?


Check the energy label for each lamp to rate the energy efficiency of each lamp.

Step 2: Determine how much light you need


Use lumens, not volts, to choose your lamp, as it is more efficient when it is able to generate the same amount of light with less energy consumption. This information is usually well detailed on all packages.

Step 3: Choose the type of light you want


Appearance of color, or as we call it in Spain, color temperature indicates color temperature and is expressed in degrees Kelvin (K).

Cool white: equivalent to 5800 K as it is intense white light, it is suitable for rooms without natural light, storage rooms or garages.
Pure white: Equivalent to 4,500K due to being light to medium density, it is ideal for kitchens, bathrooms, laundry rooms, etc.
Warm White: Equivalent to 3000 Kelvin and perfect for living rooms or bedrooms.


Step 4: what degree of openness do you need?


It is important to check the opening angle of the LED bulb that you want to purchase. These could be:

Bottom corner (40 °): It will achieve a “spotlight” effect to illuminate a smaller, more defined area.
Greater angle of openness (120 degrees, for example): More light with a single lamp, ideal for light rooms and living rooms.


Step 5:

Do you want your lamp to be dimmable?
You can check this on the packaging and it should be clearly indicated.

Step 6: is your electrical installation compatible?


It may happen that at the time of discharging the light in your home, not all facilities were suitable for using LED lights. We advise you to check this point well before purchasing.
