Buying Guide

Because it is such a common product in our lives, it may seem simple to choose the best lamp. But the fact is that if you want to save money, guarantee the desired effect and efficiency, you need to take some factors into account before buying the ideal lamp.

That is why we have created this Buying Guide. Here you will find the main information to help you choose the right lamp.

How important is it to choose the right lamp?

Lighting is part of our lives, that’s a fact. After all, we need light to see a path or objects in the dark; to read and to work, for example.

But it is also known that not just any lighting will guarantee its functionality. After all, you need a stronger, brighter light so that you can read comfortably at night.

And on the other hand, a more diffused, yellowish light can create a cosier atmosphere. Not to mention that lighting also goes beyond its functional and practical side. The fact is that it is a fundamental part of a decoration.

Because of all these variables, the choice of the right lamp has great importance. And not for nothing, today there are several types of lamps, which vary not only in terms of design, but especially with regard to colour and intensity of light they produce.

Therefore, before choosing the best lamp it is necessary to think about the lighting objective, the quantity of luminaires that will be used in the environment, the ideal lamp for each situation and, of course, the economic factor.

What is the best lamp for each room?

Each room will require different lighting. And in general terms, what will determine the type of lamp will be its purpose, whether to illuminate a room or a passage, to read, to create an intimate atmosphere, etc.

With this in mind, the most important thing is to take into account the colour and intensity of the light that the lamp will generate.

For example, the yellowish lamp colour makes the environment more intimate and relaxing. Therefore, this lamp colour is ideal for decorative purposes in living rooms, bedrooms and washrooms.

The lamp whose light is white is recommended for environments that need more clarity, such as home-office, kitchen and bathroom; besides being the ideal lamp for work environments.

But you also need to pay attention to the fact that the more efficient the lamp, the less heat it will emit, and the greater the savings on the electricity bill.

For you to have a general notion on this subject, we have gathered tips from several decorators on how to choose the ideal lamp for each environment of your home. Check them out below:

  • Living room. In the living room, and even the dining room, you can count on various types of lighting, with two being the main ones: The general, by means of a chandelier; and the local made with a lampshade, for example. The goal here should be to ensure a sense of comfort with brighter points of light.
  • Kitchen. In the kitchen you need more clarity to handle utensils and food, so experts recommend that you opt for lamps that have maximum fidelity in colour reproduction, in other words, that reproduce natural light.
  • Bedroom. For bedrooms, the ideal is to choose a lamp whose lighting is indirect, to create a calm environment. But, of course, here you can also have white light points as in reading lamps for example.
  • Bathroom. Here, the lighting should be intense, especially for those who need to apply makeup or shave in front of the mirror. Just be careful with lamps that get too hot. Also avoid reflector lamps, which create shadows on the face.

What are the types of lamps?

There are four different types of bulbs as regards their composition, functioning, efficiency, economy and safety. They are the following:

  • Incandescent
  • Halogen
  • Fluorescent
  • Leds

The incandescent bulb can no longer be marketed, even though it is possible that you may have it at home. Since July 2017, this type of bulb has been banned because it offered a risk of overheating, shock and short circuit.

The halogen bulb, on the other hand, although similar to the incandescent, does not use as much energy and does not distort the colours of objects. Known as a dichroic, the halogen lamp, however, generates a lot of heat and only has a useful life of 2000 hours.

The fluorescent lamp saves more energy than the above two. In addition, the fluorescent has a longer life span of around 6,000 hours.

But, this type of lamp has a negative factor. It has mercury inside, which is a dangerous toxic metal, and also emits ultraviolet rays that are harmful to skin and plants.

LED light bulbs save up to 90% of electricity.

This is why LED light bulbs are the most popular today. Led light bulbs save up to 90% energy compared to other types of light bulbs.

In addition, the LED lamp has an average of 25 thousand hours of life, does not generate heat and is still environmentally friendly because it is recyclable. Check out the main differences between the three types of bulbs below:

Led bulb Fluorescent Halogen
Energy consumption Very economical Economical Little economical
Useful life High High Low
Sustainability Recyclable Toxic, can not be thrown in the regular trash Recyclable

How to dispose of the lamp correctly?

When the lamp breaks or its useful life is over, it is time to throw it away. But do you know the correct way to dispose of a light bulb and the risks of this process?

The fact is that the disposal of light bulbs can be dangerous for your health. After all, throwing the lamp in the bin cause cuts due to the broken glass. This is a high risk, especially for the rubbish men who collect your rubbish.

But that’s not the only problem. Check out below the care you should take and how to dispose of each type of light bulb.


Despite the ban on this type of light bulb, if you still have them at home the correct thing to do is to dispose of them at specific collection points, whether they are public or private.

Although it is non-toxic, the incandescent lamp has metal particles in its composition, which makes its recycling impossible.

In the case of the fluorescent lamp, care should be even greater, because of its toxicity. Therefore, if the bulb has just burned out you can forward it to collection centres. Many shops and companies that sell light bulbs have these collection points.

However, if the fluorescent lamp is broken it is essential that you follow the steps below to protect your health:

  • Before collecting the broken parts of the fluorescent lamp, open all the windows so that the room is ventilated.
  • When collecting the pieces, use gloves and a damp cloth.
  • Put the pieces in a sealed bag and take it to a shop that collects the material.
  • Throw away the materials you used to collect the shards.
  • If the lamp broke on top of a beds pread or sheet, you should also throw them away as they will be contaminated by mercury.
  • If you have inhaled the gas from the lamp or cut yourself during collection, seek medical attention immediately.

These measures are important because mercury, when inhaled, can cause poisoning, coughing, dyspnoea, chest pains and other more serious problems.

Did you know that the American inventor Thomas Alva Edison (1847-1931) created the first electric light bulb in 1879?
But apart from the light bulb, he is also responsible for more than 2,000 creations. His first invention, for example, was the voting machine


Halogen lamps pose no danger to the environment or to people. As they are recyclable, it is recommended to dispose of them at appropriate collection points.

But if you are going to dispose of this lamp in the regular rubbish, take care to wrap it in newspaper and then in cardboard. This way, you will minimise the risks of the lamp breaking and injuring the garbage collectors.


Led light bulbs contain 98% of their components that can be recycled. Therefore, the ideal disposal should be done at collection points specializing in recycling.

Purchase criteria: what to consider when choosing a light bulb

After understanding the differences between the types of lamp and how to use them in each environment, it is necessary to move on to the practical part and choose the best option among so many models on sale.

To help you at this stage, we have selected the main factors that you should consider before buying the lamp. They are

Check out below, a detailed explanation of how to analyse each of these items.

Power and Lumens

Note that the power, which is measured in watts (W) determines how much the lamp will consume. For example, a 60w light bulb indicates how much electricity this model spends.

What will determine how much the light bulb illuminates is the number of lumens.

So, the higher the number, the higher your expenses will be at the end of the month. But what will determine how much the light bulb illuminates is the number of lumens.

It is therefore important to consider these two measurements together. Thus, the ideal lamp will generally have a high number of lumens and a low number of watts.


Also take into account the voltage of the lamp. Measured in Volts (V), the voltage is related to the power supply of the lamp and therefore may be 110V or 220V, and bivolt.

Already led lamps can be found with four types of voltages: 12v, 110v, 220v and bivolt. Before buying, check the voltage of the power grid in your region.

Colour temperature

The colour temperature, which is measured in K (Kelvin), is what will define the colour of the light emitted by the bulb. In general, the temperature can vary between 1.500k and 10.000k.

To give you an idea, up to 4000k, the lamp will emit a warm, yellowish light. Above 4000k, the light emitted will be whiter and bluer.

Neutral light, which is around 4000k, is the closest to natural light, meaning it won’t interfere as much with the colour of objects.


Finally, note that the shape of the lamp may be relevant depending on the type of fixture you are going to use.

Therefore, we recommend that you check if the lamp will be inlaid, apparent or if it needs to have a specific shape, size or type.

In this way you will find lamps of various models such as tubular, filament, slim, large, among others.

Extra technologies

Besides all these criteria, we suggest that you take into account some extra technologies that are starting to emerge in Brazil.

One of them is the musical lamp which, besides emitting different colours, also plays music. This occurs through connection via Bluetooth with smartphones.

The LED lamp with 360° HD camera is ideal for those who need to monitor children and the elderly at home.

This is because this type of lamp has a technology that uses an app to activate the camera that is inside the lamp and transmits images and sounds, among other surveillance functions.
