The Best Bulb Lamp: Our Picks
Check out our Buying Guide to learn all about this "magic" lamp and know how to choose the perfect light bulb model to completely change the mood and spirit of any room with a simple adjustment.
What is the bulb and how does it work?
The bulb is a type of LED lamp (Light Emitting Diode) with the shape that mimics ordinary incandescent bulbs. Unlike conventional bulbs, LED bulbs do not have a filament, which makes them more durable.
This durability is further increased by the fact that this model does not generate as much heat as the filament bulbs, which reduces the chances of overheating and burning of the bulb. The bulb operates by means of a LED strip that illuminates when it is powered by electricity.
The model has an electronic circuit that adjusts the voltage so that only what is needed for the lamp to function is consumed, resulting in savings of up to 80% of electricity compared to ordinary light bulbs.
Why invest in LED light bulbs?
LED bulbs are the ideal option for those who want a more efficient and economical lighting. Extremely durable, they have a standard format, perfect for replacing incandescent bulbs in any lighting need. Practical, they can be changed or installed by anyone.
The model provides good light quality, and most allow dimming. Some versions offer various colour options. Less aggressive to the environment, the LED bulb generates little heat and does not emit ultraviolet or infrared rays.
In addition, the long life of this bulb reduces expenses and concerns with maintenance. Another great advantage of the LED light bulb is that it does not use a ballast, requiring less power to generate the same lighting as an incandescent bulb, consuming up to 80% less electricity.
Hot, cold, neutral or multicoloured: which version of the light bulb is best?
The most popular versions of the light bulb are those with cool, warm and neutral white lights. These "temperatures" have nothing to do with the amount of heat dissipated by the bulb, but rather with the colour tone it gives to the environment.
The neutral tone is produced by 4000k lamps, ideal for environments where the interference of colours in lighting is not desirable. The warm white is more yellowish, ideal for producing an atmosphere of comfort and cosiness, and produced by 2700~3200K lamps.
Cool white is the bluer shade of light, produced by 5500~6500K lamps. It induces a feeling of alertness and attention. Finally, the multicoloured versions are the most versatile. Some have one or more shades of white, in addition to RGB colours, such as yellow, blue and green.

Where to use light bulbs?
As we have already mentioned, the standard format of the bulb lamp fits in most rooms and environments, as well as in most models of lamps and lampshades.
Therefore, the bulb can be easily used in any room, sconce, luminaire or chandelier that has screw sockets compatible with E27 connectors.
But besides the format, there are light temperatures suitable for each purpose and environment. For example:
- Warm white: Relaxes and sharpens the palate. Ideal for bedrooms, dining room, living rooms, restaurants, bars and cafés;
- Neutral white: draws more attention. Ideal for kitchens, bathrooms, offices, classrooms, and shops, in addition to environments where colour neutrality is important, such as beauty salons, art studios, and museums.
- Cool white: draws attention at higher levels and gives a clean feeling. Ideal for clinics, doctor's offices, pharmacies, hospitals and industries.
Buying criteria: Characteristics to compare and qualify light bulbs
Now that you know enough about light bulbs and their uses, we will give you some more tips for you to make the right choice. Check out the list of characteristics you should pay attention to when comparing the types and models of this product:
So that there are no doubts, check out the detailing of the characteristics:
The power of lamps is measured in watts (w), and corresponds to the amount of energy used by the lamp to provide light. Therefore, in the case of light bulbs, higher power does not mean greater lighting capacity.
The LED light bulb offers the same light output as a traditional light bulb, but at a much lower wattage.
The luminous flux is the amount of light a lamp is capable of emitting. This capacity is measured in lumens. The higher the lumens of the chosen model, the higher the luminous flux of the light bulb.
This information is fundamental to identify if the lamp acquired has the necessary capacity to illuminate the environment for which it is intended.
Colour temperature influences the sensations and impressions of the environment. Basically, warm white brings the feeling of relaxation and coziness, while cold gives a more energetic and active air.
To measure the colour temperature of light bulbs, the Kelvin (K) scale of light wavelengths is used, where lower values correspond to warm light and higher values to cold light.
In general the corresponding values are:
- Between 2600 and 3500 K: warm white;
- From4000 to 4500 K: Neutral white;
- From 5000 to 5500 K: Daylight white;
- Above 55 00 K: Cool white.
Connectors and fittings
The bulb connector is the E27, the most common model for bulbs, the one used in screw sockets. However, there are models that can have other types of connection, such as Wi-Fi or Bluetooth, for example, to control light intensity, colours and other various adjustments.
