FAQ

The light-colour of a light-source is measured by the colour-temperature. The unit for this is "Kelvin" (abbreviated: K). The higher the temperature the whiter the light appears to the human eye. Common temperatures vary from "warm white" 2.700 K - 3.000 K (similar to incandescent lamps) to "neutral white" 3.500 K - 4.000 K up to "daylight white" 5.500 K - 6.500 K.
To judge whether an area (e.g. a desk) is lightened up sufficiently, the luminance emittance is used. This is the relation between the amount of light and the iluminated area (Lumen per square-meter). The luminance emittance is measured in "Lux" (abbreviated: lx); it is one Lux when the output of one Lumen consistantly spreads on an area of 1 sqm.
LED lamps in the living room? Few years ago that sounded like a dream of the future. Currently more people are using LED lamps in their homes. And this without compromising on comfortable light. Due to the wide range of light colours, LED lamps can nowadays be used in living-, dining- or sleeping-room, in the kitchen or in home-offices.
LEDs produce more light per Watt of electric energy than conventional lamps and save up to 85% of energy-costs.
Retailers are alowed to sell the banned lamps as long as their stocks last. Of course consumers are allowed to use all the incadescent lamps they have at home and do not need to replace them by energy-saving lamps.
In executing this directive the EU and the European lamp-industry intend to reduce the carbon dioxide-emissions drastically to contribute to the environmental protection.
If you have a claim, please return to the retailer where you purchased the luminaire. He will be glad to help you.
The abbreviation "IP" stands for ingress protection. The individual protection-classes indicate the suitability of electrical devices (such as luminaires) for different environmental conditions. The numbers that follow the letters IP indicate the protection extent towards contact respectively contaminats (1st digit) and moisture respectively water (2nd digit).
The light-output of modern LEDs varies from 60 to 100 Lumen per Watt. Conventional incandescent lamps merely reach 10 to maximum 15 Lumen per Watt. Accordingly consumers can multiply the Wattage of an LED by the factor 8 to get an approximate comparison to conventional lamps. The light output of a 5 Watt LED lamp is approximately equivalent to a 40 Watt incandescent lamp.
The lightstream, mesured in "Lumen" (abbreviated: lm), is the total light performance that is emitted by a light-source. For many consumers the wattage of a luminaire is the unit for performance. But it is just a unit to measure the power consumption of the lamp. In terms of energy-efficient alternatives, like LED lamps, the amount of Lumen is noted additionally. The more Lumen, the brighter the lamp.
The lifetime of a LEDlampamounts to ca. 30.000 burning hours. As opposed to conventional lamps LEDs are less sensitive to heavy duty and are almost maintenance-free.
LED stands for "light emitting diode"and is a semiconductor that emits visual light.
Consumers can benefitswitching to energy-efficient bulbs, due to a lower power consumption of compact-fluorescent lamps or LED lamps they will save on their energy bill. Allthough the alternatives to incadescent lamps are more expensive, the extra purchase cost is in general compensated by lower energy cost after one year.
As long as the item is part of the assortment, you can easily order the spare part or the spare glass at the retailer where you purchased the luminaire.
No, that is not possible. Trio products are only available in retail shops.
