To know how to choose the perfect LED bulb for home, you have to look at certain features that we tell you here.


If you have come to buy an LED bulb to achieve energy savings, surely the choice has not been easy. To know how to choose the perfect LED lights , you have to look at certain characteristics of the bulb : the power in lumens , the opening angle of the light , the light temperature , and that it suits the use we make at home.


Led bulb: Which one suits us best?
To understand what features we have to take into account, the first thing we should know is that the bulbs differ , among other things, in the amount of LEDs they contain: they can be from 3 to 20 series . Also, in the material of which these LEDs are made: the higher the density of active material, the more efficient and expensive the bulb is (gives more light).

If a bulb with 20 LEDs contains low-density active material, if one of them is damaged, the others will also progressively, which decreases the life of the bulb. If we opt for this type of light bulbs in warehouses of unknown manufacturers, the safest thing is that they contain low-density LED bulbs, cheaper and more easily damaged. It is more advisable to purchase these bulbs from known manufacturers.


Currently, the most widespread model is the 3 or 5 LEDs, but high density, which offer enough light for a medium household use.

The power in lumens

What are lumens in an LED bulb? To understand this concept well, we have to know that the watts tell us what the electricity bulb consumes, and the lumens the amount of light they generate. LED advantage? Few watts for many lumens, which can mean an 80% saving in electricity, since it is paid according to the amount of watts consumed. It is usually a maximum of 90 lumens.

Real lumens = to the number of watts x 70, approximately.

The opening angle of the light

This parameter is relatively simple:

- A smaller angle (40º), will achieve a “focus” effect to illuminate a smaller and more localized space.

- At a more open angle (120º, for example), more ability to illuminate, with a single bulb, more space (they are commonly used to illuminate a room).

So, depending on what you want to light up, find out about the opening angle of the bulb.

Temperature

This color temperature is defined by the Kelvin degrees of each bulb. We can divide the bulbs according to their temperature into 3 types:

-   Cold white: equivalent to 5800K. More intense white light , perfect for storage rooms, garages ...
- Pure white : 4500K. Medium intensity , suitable for kitchens, bathrooms, etc.
- Warm white: 3000K. More subdued and ambient, ideal for living rooms or rooms.

What problems have you encountered when purchasing an LED bulb? Haven't you tried them yet? Given that you can save up to 80% on the electricity bill, do you think it is a good investment even if its acquisition is higher? Tell us your LED experience!
