LED Light Bulb Tips

While it is always looking to consume less energy to reduce our impact on the planet, lighting is a major area. Indeed in France, consumption Annual energy in lighting is 58 TWh. In a household, 14% of electricity consumption is dedicated to lighting.

The bulbs LED is undoubtedly the most energy efficient bulbs but facing increasing rates, it is sometimes difficult to navigate. Here is a quick overview to see more clearly.

The LED briefly

The LED is an average lifetime of 50 000 hours or between 15 and 20 years depending on the use made of it… it’s50 times more than a conventional bulb or 8 times more than compact fluorescent

LED (Light Emitting Diode) is an electronic component that emits light by excitation when traversed by an electric current. Unlike the incandescent lamp, it has no filament and therefore heats very little. The current can pass only in one direction and will produce either monochromatic light (red, green, yellow or blue) a polychromatic light (white of our lighting is by changing the blue LED).

A bulb can be made with conventional LEDs that have existed for decades, which generally served as controls eves our electronic devices, or LEDs enhanced with a wide angle. The first have a small angle of the order of 15 to 30 °. The wide-angle LED will rather have an angle of the order of 100 to 140 °

Different selection criteria for its LED bulb

The form: LED bulbs are available in the same manner as other traditional halogen bulbs or incandescent and the same dimensions spot, round, globe, flame, twisted …

The pellet: LED bulbs are available with all existing caps as well as other bulbs. Here is a list of the most popular pellets: small screw, large screw, bayonet, GU 5.3 format GU10 format G9 or G4 …

Angle: For a small area to be illuminated is called classical LED bulbs (see tips on http://www.top-engineering-schools.org/lights-how-to-choose-right-led-bulb.html) will be rather to use because its angle will be smaller hence the fact that it is a directed lighting. In contrast to the main lighting of a room, the ceiling for example, it will move toward a wide angle LED that has a larger light power by its much larger angle.

The illumination color: For lighting comes closest to natural light, it is considered necessary that its color temperature is between 5000 ° K and 6500 ° K ( NB  : temperature in Kelvin K = Celsius temperature C +273.5). There are several colors of lighting available on the market: the warm white, warm white light, natural white, cool white or very cold white. The higher the color temperature is high and the light will therefore be called cold and white. Conversely the higher the temperature light is low and the light will be called hot and therefore provide a yellow light.

Power: For bulbs power is calculated in lumens. We must start from the basis of calculation as 1000-1250 lumens = 100 Watts (actually rendering Watt is sometimes slightly different)

It is therefore necessary to know the equivalences before changing the bulb. Here are some examples of equivalences.

1.5W led = 15W = 25W Halogen incandescent et 5W LED = 50W = 65W Halogen Incandescent

Its price: The average price of a LED is 11 €. This is seen for what use they wish to use and also the range which is desired. LED better and with greater life will inevitably be more expensive because it requires more advanced technology although the overall price tends to fall more and more. Finally, a light bulb that is intended for professional use will not be the same as a light bulb for the individual. For professional use its price up to € 70-80.

The bulbs labels gives extensive information on the characteristics of the bulb. Generally observed wholesale energy class of the bulb. It goes from A ++ to E knowing that the A ++ being more energy efficient. There is also the kWh consumption, lifetime, power, color according to degrees Kelvin (K), the angle of illumination and of course the size of the bulb. The choice depends on your equipment and use you plan to do with your LED bulb.

It is true that the price at first higher purchase a standard bulb… But ultimately it uses less energy, it is to change much less frequently than a conventional bulb … Last not least, its impact on the environment and health is almost zero since it is completely recyclable and that it has no dangerous gases. Then your light bulbs for a healthy and efficient energy future!
