> Types of bulbs

The incandescent light bulb classic is expected to soon disappear for ecological reasons. Indeed, it heats more that it enlightens.Its service life is 1,000 hours.

The compact fluorescentbulb consumes on average 5 times less energy than most of the bulbs (not counting the LED). It can work between 5000 and 10 000 hours.

Attention: the compact fluorescent bulbs require special precautions. They produce electromagnetic radiation that can be harmful if we approach less than 30 cm.

The LED bulb produces a lively and directional light. Its price is higher than the average, but with her electricity is not wasted. The real strength of this energy saving bulb of longevity with up to 100 000heures of lighting.

The halogen bulb is also very greedy but very powerful lighting electricity. It can last for about 3,000 hours.

> Different forms of light bulbs

The bulbs can be shaped: pears, globe, flame, etc. Each shape has two kinds of different nerve: screw or bayonet.

The selection criteria

> The power and intensity

First of all, lighting, there is a rule to remember, it’s never choose a bulb whose power and intensity would exceed those indicated on the fixture. The efficiency of a light bulb is measured in Lumen per Watt, or the amount of light produced by electricity it uses.

Medium lm/W 25 30 75 80

The higher, the more the light strength and energy are optimized.
> Energy saving

The halogen bulb consumes on average 45W. The compact fluorescentbulb moves ahead with its necessary 25W. Real energy leak, the incandescent light bulb uses 5 times more electricity than the fluo-compact. The champion of the category remains the LED bulb that uses only 1W to illuminate.
> The piece of concerned home
The general rule is to spend 15 to 20W per square meter for the living rooms and 10 to 15 W for those in which it’s just passing and in the rooms. Divide these figures by 5, if you use the bulbs energy saving.

Compact fluorescent bulb For the parts of life that can ventilate easily (these bulbs emit dangerous gases). They are not so made to places of passage, to a hallway, sanitary facilities, etc.
Incandescent bulb In every room of the House. Their glass is clear or frosted, the light will be more or less strong.
Led bulb In the parts where the light should stay lit.
Halogen bulb Nice in the living rooms, they are especially useful for reading or working, because they give off a bright light.

> The price

Incandescent and halogen bulbs are the least expensive. LED and compact fluorescent bulbs require a few euros more.

> The duration of life

The LEDbulb has the largest life, followed by the fluo-compact and halogen. As for the incandescent light bulb, she arrives far behind with a lifetime up to 100 times less than the LED.

> The price/quality ratio

The LED bulb is the most cost-effective bulb at the value level. For almost the same price as the bulb fluo-compact, or a little more expensive, the latter can 100,000 hours of light.
