Ranking: The 4 best LED lamps on the market
Buying an LED lamp goes beyond choosing the model. It needs to be efficient, durable and suitable for your lighting goal. Knowing this demand, more and more manufacturers have made innovations in this product.
That’s why we are going to present you the 4 best LED lamp models available on the market.
It may seem simple to choose an LED lamp considering only the shape. But there are different specifications that impact efficiency and energy consumption.
In order for you to choose the most efficient model, we have prepared this Buying Guide with everything you need to understand before purchasing your LED lamp.
What is an LED bulb?
The term LED stands for Light Emitting Diode or, in free translation, light emitting diode. The diode is an electronic component that generates light with low energy consumption and is sustainable for the environment.
For this reason, the LED lamp is capable of generating the same amount of light as it did, for example, the extinct incandescent lamp, but using less power. Thus, the LED lamp can transform up to 90% of the energy used in light.
To give you an idea, incandescent lamps used to transform only 20% of energy into light. The rest, about 80%, turned to heat. In other words, a light bulb of just 10w is equivalent to the old 60w incandescent.
Due to this high efficiency, the use of the LED lamp impacts your electricity bill, which comes much cheaper at the end of the month.
What are the advantages and disadvantages of the LED lamp?
The advantages of an LED lamp are not restricted to enormous energy savings.
This product also has a lower maintenance cost, light beam with different angles, does not emit ultraviolet rays – which is harmful to health – and has low heat emission.
And there’s more! The LED lamp has a longer durability, because it does not have filaments that heat and because they are made of more resistant materials. The life of the LED lamp depends on several factors. But, in general, they are made to run up to 50,000 hours.
This means that the LED lamp can last up to 17 years if used 8 hours a day, or 45 years if used 3 hours a day.
The fact is that the LED lamp does not burn as it did with incandescents, but its brightness decreases with time. Due to the manufacturing material, the LED is also shock, vibration and external impact proof.
That is why they are also widely used in outdoor areas, such as gardens and even on public roads. Another advantage of the LED lamp is that it has no mercury or other toxic material and is 100% recyclable.
However, even though the advantages of the LED lamp are immense, this product also has its disadvantages. And the main one is still the price. In the past, they were much more expensive compared to conventional lamps.
Today, however, it is already possible to find LED lamps with more competitive prices. Still, the cost-effectiveness of LED is greater in the long run, due to its long service life and low cost of replacement and maintenance.
The following are the main advantages and disadvantages of the LED lamp:
What is the difference between LED, fluorescent and halogen lamps?
Since July 2017, the incandescent lamp has been banned from being marketed because it offered a risk of overheating, shock and short circuit.
As a result, there are 3 options of lamps for home use: halogen, fluorescent and LED.
The halogen lamp is a variation of the incandescent and is known as the conventional dichroic. However, this type of lamp still consumes more energy than fluorescent and LED ones, in addition to producing more heat.
Fluorescent has emerged as a more economical option compared to the old incandescent. However, this type of lamp has mercury in it and, therefore, it cannot be thrown in the common garbage.
In addition, the fluorescent lamp emits ultraviolet rays that are harmful to the skin and plants. Another disadvantage of this type of lamp is that its useful life is up to 15,000 hours. In other words, much shorter than the LED’s lifetime.
For you to understand better: a 10W LED light illuminates the same as a 15W fluorescent. This corresponds to savings of almost 35%. Below are the main differences between the three types of light for homes:
The prices of the LED lamp vary according to the intensity of the lighting, the shape and other variables. Today on the market, you can find models that cost between R $ 25 and R $ 600.
It is worth mentioning that the LED lamp must have the Inmetro seal, which guarantees the quality of the product.
Where to buy?
You can find the LED lamp for sale in stores specializing in electrical and department stores, But to find a greater variety of models and more affordable prices, the ideal is to make your purchase in online stores such as Amazon. So, you buy your LED lamp safely and comfortably.
Purchase Criteria: Factors to consider before purchasing the LED lamp
Now that you know all the benefits of the LED lamp, it’s time to understand what differentiates one model from another. We have listed below the main factors that you must take into account before choosing the LED lamp:
- Power and Lumen
- Color temperature
Next, we’ll detail each of these factors so you can make the best decision.
First, you must choose the model of the LED lamp. Nowadays, the market offers several types, such as: bulb, spiral, tubular, corn, candle, dichroic, globe, high power, etc.
- Pair and air : These models are ideal for replacing halogen lamps, as they guarantee energy efficiency.
- LED dichroic : It is also recommended to replace the halogen dichroic. This type of lamp is ideal for lighting the internal parts.
- Tube : It is recommended for commercial spaces and offices, but it is also the most expensive model.
- Bulb : The Bulb model is the one whose shape mimics the old incandescent lamps and is usually the most popular.
- Filament : This is the news of the moment, filament LED, which displays the wire and is known as retro LED.
This model has the same characteristics and advantages as the ordinary LED lamp, but with the appearance of the extinct incandescent lamp. This gives a more cozy light and charm when the lamps are exposed.
Lumen and Power
The Lumen, or luminous flux, is the amount of light emitted by the lamp. Power, measured in watts, refers to energy consumption.
In the case of the LED lamp, the combination of these two variables is what will determine the efficiency of the product.
That is, the greater the number of Lumens, the more light will be emitted. And the lower the number of watts, the lower the power consumption. If you want to know more, check out this video from the Learn and Build channel:
LED lamps can be found with 4 types of voltage, 12v, 110v, 220v and bivolt. Before buying, check the voltage of the electrical network in your region. It is worth mentioning that the 12v lamp emits a more cozy and weak lighting.
When in doubt, we always recommend that you choose the bivolt. It has no price difference, it is ideal for all situations and you are not at risk of having purchased the wrong voltage.
The temperature of the LED lamp, despite its name, is not about heating. This factor determines the color of the light that will be emitted and will depend on the lighting effect you want.
Measured in kelvins, the temperature varies between 1,500 and 10,000. Up to 4000k, the LED lamp will emit light of warm yellow tones. Above 4000k, the light emitted will be more white and bluish.
