94 / LOOX OVERVIEW THE LOOX LIGHTING SYSTEM FAQ Questions and answers Test of service life in accordance with the LM-80 standard? Häfele tests LOOX LED flexible strip lights in accordance with the LM-80 standard. LM-80 is a standardised testing method, which allows products to bear the EPA's (Environmental Protection Agency) Energy Star. The test is a manufacturer-independent comparison of LEDs. During the test the luminous flux (Lumen maintenance) and the service life of an LED are tested at three different temperatures (55, 85, and 105 °C) for 6,000 hours. Lead in LOOX products LOOX Products by Häfele are lead-free and adhere to the RoHS guidelines. Heat generation of LEDs All light sources produce heat, even LEDs. However, they do not become very hot, especially if the LEDs and lights are fitted with “heat sinks”, which help to lead away heat from the light LEDs and foodstuffs As LEDs do not emit UV radiation, they are the better option for supermarkets, restaurants and kitchen lighting. UV radiation reduces the nutrient content in foodstuffs, and all other light sources – including natural and artificial – emit UV radiation. It must also be taken into consideration that LEDs emit less heat and keep foodstuffs fresher for longer. Infrared radiation from LEDs LEDs do not emit infrared radiation, like incandescent bulbs do. Service life of an LED Up to 50,000 hours. LED A light-emitting diode (LED) is a semi-conductor element that emits light when electricity passes through it. This semi- conductor element consists of a crystal that is attached to a metal holder, and are both encapsulated in protective plastic. LEDs are mostly based on inorganic, i.e. non-carbonic materials. OLED Organic light-emitting diodes (OLEDs) are based upon organic (carbonic) materials. OLEDs are manufactured in thin layers and therefore provide a diffuse light source. The OLED technology is becoming more frequently used in display applications (e.g. mobile phones and PDA screens).
