The LED bulbs or led lights.
What is the advantage of an LED bulb?
To know the advantage of an LED bulb, it is interesting to compare the different types of light bulbs we can find in trade compared to their luminous efficiencies and their estimated lives
The incandescent light bulb, light efficiency 10-20lm/W and an average life in hours of 1000 to 2000 h.
The bulb Halogen light efficiency 15-20lm/W and an average life in hours of 2000 to 3000 h.
The fluorescent bulb or CFL light efficiency 40 to 70 lm/W and an average life in hours of 6000 to 15,000 h.
The bulb LED light efficiency 40-135 lm/W and an average life in hours of 15000 to 50000 h.
The reported figures above are indicative and are an average of the quoted bulbs.
For our houses, we use mainly connecting directly to said AC 230 Volt bulbs.
For a LED bulb gives optimal effectiveness, it is important to keep it cold. Unlike a halogen bulb, the LED bulb is composed of electronics allowing the operation of / diodes.
LED bulbs produce no heat toward the front of the bulb, but heat from the back (electronic component). If the bulb heats up, this type of bulb life may be reduced and will turn in an average of 15000 h.
The price of an LED bulb can vary from single to triple, for the same amount of light announced. What will differentiate its price will be the quality of electronics allowing its cooling and therefore its durability and also the quality of the diode used.
What it shows, LED bulbs have a much longer life than most other bulbs for a luminous efficiency that can be up to two times more efficient.
Ignition and extinction of the bulb will be fast without the risk of damaging it, unlike the CFL bulbs only giving 60 percent of their power after 60 seconds.
Variety of color temperature:
Unlike our old bulbs, LED bulbs allow to choose the color by the bulb, we can distinguish three color families.
Warm white: 2700K to 3000K
It's color temperature comes closest of halogen bulbs. The broadcast color will be a warmer and more yellow hue. This color temperature is typically used in parts to live as the living room and dining room.
The neutral white: 4000K to 5000K
Neutral white LED bulbs give a clear light that can be compared to natural light very slightly warmer. This color temperature is mainly used in parts such as the office, because it helps stimulate concentration. We may also place this type of color in the bathroom near a mirror, this color temperature allows by its whiteness to return more than just outdoor light rendering and prevent our ladies a surmaquillage.
The cool white: 5000K to 6000K
A bright hue, this color to highlight your outside in the evening. This temperature is the color of the light of day.
The main types of LED bulbs.
There are several formats and sizes of LED bulbs as a result, it is possible to replace all our old incandescent bulbs, our bulbs halogen, or even neon desampoules compact by the new generation of LED bulbs.
Replacement of our old light bulbs to incandescence, the bulbs are nerve bulbs screw type e27 LED bulb or large screw.
The bulb e14
Screw diameter smaller and often flame shaped, bulb e14 will be mainly used in small lights or chandeliers composed several bulbs.
LED GU10 bulb
It's the most used bulb in our spots ceiling, our Halogen reflector bulbs replacement. This type of bulb to choose the desired color temperature and light distribution angle. Some bulbs will also allow the variation of intensity.
The bulb GU5, 3
Mainly used in the relamping, bulbs LED GU5, 3 are used in plants of type low voltage and require a transformer.
