Following the scheduled disappearance of incandescent bulbs in favour of low-energy bulbs, you are more and more interested in the “Led” bulbs.
The first reviews on the lighting low consumption comes from the fact that most Led bulbs sold in supermarkets are not powerful enough and broadcast a cool white.
Today equipped largely to Led lighting at home and convinced of the outcome, I’ll try to you “light up” a little more on the issue…
In fact, it was difficult to find some Led lights that offered the same performance as a light bulb 60 W incandescent or more, I tested a good ten past three years without to be seduced.
In general, you could find this type of bulb (see picture below) with 8 or 16 Led so-called “Classic” but the result wasn’t really there.
Now, it is possible to find new Led bulbs so-called generation of ‘ power ‘ at specialist dealers.
What’s the difference?
Led so-called “Classic” already very old (1960’s) gives only a weak light output that degrades quickly in time.
The Led so-called “power” when it delivers a power of 1W minimum for excellent performance.
What kind of light bulbs?
You can find all types of equipped Led bulbs of power, the most widespread for the recessed spots GU10 or screw (E27 or E14) for chandeliers and suspensions, or even outdoor spot lights and tubes fluo type…
Certainly a higher purchase cost, the lifetime of a Led bulb is significantly higher (more than 30 000 H) to that of an old bulb incandescent (1 000 hours) and in terms of consumption, we’re approaching the 80-90% energy saving.
The cost of annual consumption of a 60W incandescent bulb is about € 4.50 for an 8W Led bulb and an equivalent rendering of €0.60 will be. I let your calculation and you will see that the global economy is far from negligible.
A Led Bulb E27 of 7W bulb is equivalent to a rendering of 6OW in glowing, his luminous power is 700 lumens and its diffusion angle is 180 °.
For an equivalent to 50W 4W GU10 spot, you get a bright record of 380 lumens on a broadcast of 35 ° angle.
There is a choice between the white “Hot” or “cold”.
White hot procurea a yellow close that we usually use in our homes, it will be used preferably in areas of life such as a stay or a kitchen.
The cold white when to him is close to the natural light of day. It provides a white light that is more suited to environments (workshop, office) work or rest (living room, bedroom).
I chose to perform the test on the main lighting in my office, suspension type E27.
Shooting in daylight without flash.
The second shooting occurred at night and without flash. Left a light bulb Led E27 10W white cold and right a fluorescent bulb compact 18W.
We can see that the Led bulb performance is excellent and even in cool white.
Another example of outdoor lighting with this cool 900 lumens white 10W Led floodlight.
You can find Bulb bulbs or spotlights recessed around €20 a piece in some specialty stores.
For external projectors, it will take between 50 and more than 200 according to the power.
To replace your neon lights by Led tubes, it will cost between 50 and €80 room.
These new generations of power Led bulbs are very efficient and the lighting quality is really there.
It is easy to divide consumption by 8 by replacing its filament bulbs, and even though the cost may seem high, the installation will pay for itself in a little less than 3 years.
A life expectancy of about 35 000 H, you’re quiet for a few years, besides these bulbs are generally 5 years warranty.
An example with my kitchen of 10 spots GU10. My consumption was before 350W total replacement by GU10 Led 3W for consumption divided by 10…
Thanks to our partner “Led and fluorescent”, a lighting specialist low-power that allowed me to test the many Led bulbs. ”
