Now essential, Led with its colors and adjustable intensities upset our relationship to light. In the House or in the garden, custom moods and connected solutions improve our well-being.
This applies in aluminium with glass diffuser is ideal with a Led light bulb filament. Al. Black Edition, “Buzzard”, €29.99 (bulb not included). PhilipS.
With the ban on incandescent lamps, which accounted for 90 percent of the market 10 years ago, a few years were sufficient to Led (light-emitting diode) democratizes and revolutionizes the world of illumination. This alternative to CFLs and halogen bulbs (scheduled for the disappearance in September 2018) is called to supplant other light sources.
Prices have dropped considerably (about €10 for an equivalent bulb 60 W) and still slightly should settle. The performance also improved. First Led bulbs were to disadvantage a reduced angle of diffusion. They offer today, as long as you choose (there are still models < 140 °), a better distribution of light (> 300 °). At equal power, luminous flux is also higher.
“To replace a lamp 60 W incandescent (approximately 700 lm), we advocated today a 6 W, against 10 W Led lamp three years ago,” says Pierre Taing, head of Led at Feilo Sylvania products. Energy consumption, already very low, is still reduced.
A Complete Range
A brake on the development of the Led was its low power. It is now lifted. The supply has grown bulbs up to 100 W incandescent equivalent. There is even still higher powers, especially for outdoor lighting, where the Led has the advantage of being insensitive to temperature changes. In this case, the light fixture and bulb become one, with interesting design possibilities for a reduced price. These solutions are coupled to more decorative products (powers < 7 W), used for example for the markup (in a staircase) or to create light games (strip of LEDs around a mirror or recessed into a false ceiling). The Led now offers an alternative in all the product lines, including the “pencils bulbs” (R7S) and G9 halogen bulbs and, with however a few problems related to the transformer, G4.
An Offer Vintage and Deco
The bulb filament surfed on retro fashion and offer diversified. The first models appeared three years ago. Include Girard Sudron or Calex. Their micro-Led structure based on small willing vertically filaments reminds the aesthetics of incandescents. We find patterns standards, flames or spherical, transparent glass or amber to give a warmer tint. The purpose is not to light the room strongly but to create a comfortable atmosphere. The range “1906 Edition” of Osram bulbs, for example, appear equivalent to 35 W powers. There are also deco filament Led light fixtures , taking over the design of the old incandescent lamps (range ‘SylCone Retro”Feilo Sylvania, for example).
The Led also upsets our lighting habits by providing new features, including the creation of light environments. To dare one not in this universe more “techno”, and for a low price (€12.99, for example, for a light bulb double click “Veezio” at Castorama, equivalent to 60 W), we can already try a light bulb “2 in 1” or “double-tap” which allows to change the intensity of thelight, without changing the light switch or electrical installation. At Osram (range ‘Double click’), for example, a simple click of the switch and the light bulb turns to 100% intensity. double click and it lights up to 40%, without changing the color temperature. The manufacturer also offers a light bulb (“Active and Relax”) allowing to choose, by this same system, white neutral/cold (4 000 K) and warm white (2 700 K). At Castorama, the choice of the intensity is accompanied by a change in color temperature (4 000 K to 100%, 2 700 K 70% for a more friendly atmosphere).
Ambiance Zen Or Fire Wood
The “Veezio” range is also available in “3 in 1” with a remote control to adjust the intensity of light and to vary the colors. Philips launches this summer a bulb ‘triple click’ (range “SceneSwitch”) with three different intensities (100%, 40% and 10%). Luminaires equipped with a dimmer, there are also bulbs allowing to vary the color temperature (from 2 700 to 2,000 K, very warm light, with the line “Dim Glow” of Osram), without amendment this time of light intensity. To go even further in the concept of comfort and improvement of habitat by lighting, the Jedi, launched by the French brand “iDual” concept that provides pre-recorded and managed by a remote control lighting scenes. You can choose between a fire wood or zen atmosphere, for example.
Following the big trend of the moment, lighting becomes it also connected. First commercialized in the Apple Store, the solution “Hue” Philips has paved the way (see box p. 85). The kit, including a bridge (the element of communication connected to your internet box) and light bulbs or lamps dedicated, allows to control the lighting from an application: simulation of presence through remote control, light therapy to stand up or lie down in sweetness, harmonization of the light depending on the climatic conditions, synchronization of light with the music… the possibilities are numerous. Other manufacturers also offer connected solutions: Osram, with his basic kit “Lightify” including a gateway and a bulb, finds applications inside and outside the home; Jedi, launched the “Wiz”, the only one currently operating in wifi and able to identify the pieces, for example to program the extinction of lights in children’s rooms.
Color Temperature, What About You?
The world of lighting used to be simple. You buy a bulb incandescent and you had a beautiful warm light. With the Led, you now have the choice of the color temperature. Simply put, it is even cooler that its value is high. They prefer warm temperatures (< 3 300 (K) for the living room and bedrooms, and a neutral temperature (4 000 K) or more cold (> 5 300 (K) for the kitchen or the bathroom room, but also for the office because it has been shown that a temperature of cold light promotes concentration.
Decrypt the Packaging of Blisters
The most important information is: Power and its equivalence, more evocative, with an incandescent bulb. The luminous flux indicates the amount of light provided by the lamp. At equal power, it allows to know which bulb lights up the best. Color temperature determines the lighting ambiance: warm, neutral or cold. A pictogram indicates If the bulb works with a dimmer . But it is not enough that the bulb is dimmable, the drive must also be ‘end of phase ‘. The most recent (< 5 years) are generally. Philips, notably, fills in the list of compatible drives on its web site. Note, the Led lights instantly, unlike CFLs that require often more than a minute to get 100% of the luminous flux. Finally, be aware that the Leds are ranked A + or A ++ (against C for a halogen bulb).
