Reading lamp KELVEEN
KELVEEN combines powerful LED technology with light comfort and aesthetics. The latest generation of optical components and steplessly dimmable 1,000 lumens provide the best visual comfort. Ball joints in the foot and shade of the lamp ensure easy adjustability. No visible cable disturbs the reduced optics, since the power supply is continuous in the luminaire arm. The table lamp is easy to control via a dimming switch, while the side lamp and the floor lamp have a touch dimmer on the tripod. The table lamp has been awarded the German Design Award.

A few information about the technical data
- What is luminous flux?
The luminous flux Φ - measured in lumens (lm) - is the light output of a light source. It describes the power emitted by the light source in all directions in the visible range. To get a rough idea of what this value means, here are a few comparisons:
Candle: 12lm
230V halogen bulb with base GU10, 50W: 345lm
230V halogen bulb with base G9, 60W: 740lm
12V halogen bulb with socket GX5.3 (GU5.3), 35W: 450lm
12V halogen bulb with socket GX5.3 (GU5.3), 50W: 720lm
12V halogen bulb with base G4, 20W: 257lm
12V halogen bulb with base GY6.35, 50W: 840lm
230V halogen rod with base R7s, 100W: 1200lm
- What does color temperature mean?
Roughly speaking, the color temperature indicates how warm or cold especially white light is. The oneness is Kelvin (K). The lower the Kelvin value, the warmer the light gets. The light of a commercial light bulb here would correspond to about 2700K, a candle has about 1500K. The higher the Kelvin value becomes, the colder the blue becomes the light. Daylight is compared with about 7000K. A rough classification of the light color is:
- 2,700 to 3,250 Kelvin: warm white
- 3,250 to 5,250 Kelvin: neutral white
- 5,250 to 8,000 Kelvin: daylight white
- What does the color rendering index called RA or CRI?
The color rendering index indicates the degree of correspondence of the seen body color with its appearance under the respective reference light source. The smaller the deviation, the better the color rendering property. A light source with RA = 100 reproduces all colors very well. The lower the RA value, the less well the colors are rendered. In bathrooms and dressing rooms with mirrors, we generally recommend the use of luminaires and light sources with a high RA value of at least 90.
RA 70-80: medium color rendering
RA 80-90: good color reproduction
Ra 90-100 very good color reproduction
DIMMING BY TOUCH
Switching on / off: After connecting to the power supply, briefly touch the two touch surfaces above and below the isolating ring to switch on the luminaire. By repeatedly briefly touching the touch surfaces, the light turns off.
Dimming: Prolonged touching of the touch surfaces starts the dimming process. The reversal of the dimming direction occurs with repeated, longer contact. Achieving the max. Brightness value is signaled by short flashing of the LED. At min. Brightness value stops the dimming process.
Another special feature is the so-called socket function. Here you can set whether the light is switched on or off when the supply voltage is switched on. This can be important when using switched sockets.
