A LED Bulb to Save Light Bill How to Choose

When one arises saving in the electricity bill, In addition to make responsible consumption, have products efficient is part of the equation. If we refer to light bulbs, compact fluorescent low-type classic have tough competition in the LED bulbs.

When we went to buy a LED bulb and have to choose a suitable model it is usual that doubts us to see its price. There are models with a large difference in price and features that must be considered to ascertain when buying a LED bulb. In Engadget we have developed a shopping guide with the reasons why choose LED technology for our light bulbs, as well as tips and key deciding points What LED bulb buy.

Why choose a LED bulb

Within the market of lighting, the types of lamps that are currently best fame are the LED bulbs. They are considered low-consumption models but which based its operation in the inclusion of LEDs instead of fluorescent compact as the current.

LED bulbs are firstly more efficient models When it comes to produce light, telling media with an 80% saving on the incandescent, but also taking some advantage to the classic low-consumption. A few 14 W LED bulb has an equivalence with a few 100 W incandescent and a low consumption of about 20 W.

More choices, less consumption, cleaner and with longer shelf life, but also much more expensive that those of low consumption

In addition to greater efficiency, LED technology is a significant increase of the useful life of a bulb, placing media on models of quality above the 40,000 hours.

Other advantages of using LED lights has to do with that your ignition is instantaneous, There are more options to choose by color temperature, they can be adjustable and are also considered less polluting, presuming especially does not contain anything of mercury, which is one of the disadvantages of light bulbs of low consumption fluorescent type.

At the level of design, choose the LED technology allows companies a more differential production of light bulbs, adapting formats with both classic and the low consumption it is not so easy to achieve.

View all these advantages, why not spend is already light LED in all cases? As a matter of cost. Except in business environments or public spaces, LED bulbs change does not imply a savings that we can pay off in the short term (in a home would be half over 10 years) and only makes sense when you have to make a substitution.

We must also not forget of the quality of LED bulbs we buy. In affordable ranges that are not reference, it is common for elements of its electronics to fail prematurely (especially including transformer) or its luminosity also soon be what brand your theoretical life useful by the use of more LEDs of less quality or not appropriate diffuser material resulting in a performance with a temperature higher than the recommended (LED lamps do not emit infrared light and heat should dispel in the elements of construction)

How to choose a LED bulb

When deciding What LED bulb buy to replace the incandencentes or classic, low consumption the design, Cap or price It is not the only thing that you should look at. The specifications tab there is a series of indicators and characteristics that you must take into account to make the LED bulb you choose the most appropriate.

Consumption and efficiency

  • Power: It is measured in Watts and is what consumes the bulb. LED bulbs the correspondence of power and the amount of light generated is not as direct as in other categories. The smaller, consume less bulb.
  • Equivalence in Watts: It is the equivalent power of an incandescent lamp with the same light output
  • Energy efficiency class: as in appliances, is a visual way of knowing how efficient it is a bulb
  • Power factor: one of the keys to LED bulbs. It is a reference to the amount of energy the bulb transformed into light, which is indicated on a scale of 0 to 1. In LED lights this value tends to be high, above the 0.7 on good models, which means that 70% of energy turns into light.
  • Luminous flux or light emission: It is the measure of the amount of light that can produce a light bulb measured in lumens. This feature is a good indicator of the quality of an LED as you can offer a large flow with little power. If this fact is not indicated, it can be calculated form approximate as the number of Watts on 70.

Duration and performance

  • Useful life: indicates the number of hours that the LED bulb will work properly
  • Ignition cycles: This number represents the times that we can turn on / turn off the bulb until it begins to fail
  • Power/Preheat time: It is the time that elapses until the bulb reaches 60% of its luminosity. In the case of light bulbs LED is usually instant.
  • Maintenance factor (of luminous flux): is the percentage of luminous flux that assures when after hours of useful life under the conditions laid down. A 0.7 turnover tends to be adequate.
  • Adjustable: If we are going to use the bulb with a regulator, we must ensure that it is compatible and thus implies the manufacturer

Appearance

  • Color temperature: It is measured in degrees Kelvin, and corresponds to the tone of light from a light source. Higher colder, and blue will be the source of white light
  • Light tone: the definition depends on each manufacturer and indicates the type of light that we get with a certain temperature of color in everyday language.
  • Colour rendering index: one of the strengths of LED bulbs and which is related to the quality of the light. It represents reliability of light in comparison with natural light. Shown on a scale from 0 to 100 and how much more is high, more quality of light gives the LED bulb.
  • Angle of light: It is the opening angle of the light beam. Depending on the type of lighting is being sought (wider or more concentrated), thus should be this data.

The best brands of LED bulbs

Along this shopping guide you have been counting Why change the lighting to LED modeling to make its advantages (mainly consumption and service life), as well as the keys to better choose the LED bulb that will fit our needs. There is actually the key to choose a model or other.

In the market there is a plentiful supply but you have to be quite careful with models that we acquire. Although it depends on each model and its benefits, as a general rule LED bulbs are still products with a price well above the equivalent low-consumption models. And hence the temptation to save with models of unknown brands. In those cases we have more likely that dissipation material is not suitable or that despite a price lower, is that just failing much before it should be by technology, or worse quality LEDs that must be grouped using.

As a general rule, It is advisable to resort to well known within the world of lighting brands, including:

  • Philips: the lighting reference has a vast catalogue of LED bulbs both in format and in performance. And price, as there are good packs as the two LED 60W equivalent coming on Amazon for 9 euros. It includes models for appliances and devices that you want to also make the leap to the world LED.
  • OSRAM: another classic of reference that, regardless of the type of need of LED light that we have, we ensure a minimum of quality and guarantee.
  • IKEA: the only Nordic manufacturer sells type LED bulbs in its stores, and is one of the best options when we want to get a set price without sacrificing the quality and safety of a powerful brand.
  • LG: some classic electronics manufacturers have burst into the business of LED lights. LG has a Downlight type models and also models classic, halogen type and tube.
  • GE: its catalog is not as broad as the classic brands, but they are a good alternative if we opt for classic and less decorative models.
