There are several types of lamp covering practically all fields of applications. All this variety raises a big question at the time of purchase: what is the function and indication of each? The following is a practical guide of main models available on the market: incandescent, fluorescent, halogen, LED and discharge lamps.
Incandescent bulbs are the oldest in the market and are suitable for residential and commercial use, as well as are present in the inner lighting of refrigerators and stoves.
Is a type of lamp with a low luminous efficiency (15 lm/W) and with the shortest lifespan—on average about 1000 hours—your light is yellowish and emit heat. For being a big energy consumer this type of lamp is being replaced gradually and the main alternative have been fluorescent lamps.
Fluorescent lamps, also known as electronic lamps feature high efficiency (from 50 to 80 lm/W), can last up to 10000 hours and have low energy consumption. Are available in three models: tubular, electronic and non-integrated compact compact.
The compact model has virtually the same efficiency tubular model, but with reduced size. The difference of the compact model and non-integrated electronic Compact is the first presents the embedded based reactor, the second does not, as well as the tubular model.
Are best known in white or bluish, but we can also find other similar options in the light of the common incandescent bulb. At the time of purchase, search the packaging where will be present the word Kelvin (K), as unit expressed the appearance of color of light emitted. The higher the color temperature, clearer is the hue of color of light.
The lighter shades (white or bluish) are suitable for lighting of dynamic environments, such as work areas, kitchens and service areas. The shades of soft light (yellow) are suitable for warm environments, such as bedrooms and living rooms.
Halogen lamps have an operation similar to the incandescent, but are named so because they have halogen in your Constitution. They present the advantage of being able to recover the heat released, reducing the need for electricity to keep your lighting, and so is also considered a more economical alternative to incandescent bulbs.
This type of lamp is possible to achieve a service life of up to 4000 hours and an income of around 25 lm/W are available in various sizes and shapes to suit a variety of lighting applications.
This type of lamp emits a constant clarity with self-control of the light, a lighting solution, ideal for highlighting objects or specific area allowing the creation of projects that make the environment more pleasant and sophisticated.
The LED lamps are considered the most technological lamp type available on the market. Its technology converts electricity directly into light energy, through small embedded chips, your energy consumption is very low and features an extremely long life — roughly 25000 hours. Are also an alternative to incandescent bulbs, with only 10 W illuminate the same as 60 W incandescent, generating a reduction of over 80%.
They are commonly used as accent Lighting in residential and commercial environments, but the price is relatively higher if compared to other types available lamps. However, it is noteworthy that they are the most suitable for not polluting the environment and provide a higher cost-benefit ratio for those who buy them.
Discharge Lamps (HID)
The principle of operation of discharge lamps is based on conduction of electric current in a gaseous medium. So the models available on the market differ by the type of gas used in the process of unloading. They are: metal multivapores, sodium vapor, mercury vapor and mixed lamps.
All models feature low power consumption, have relatively small size and the light produced is extremely bright, allowing the lighting of large areas. Are usually used in places where color reproduction is not an important fact, as on public roads, and also on internal lighting of large shops and factories based on LightingHowto.
Now that you already know the main types of lamp, be sure to comment which you use in your home and work environment.
