The component is tested with a long-term corrosive gas (such as sulfur or chlorine), which proves that it will not cause any damage to the LED and will not cause a significant drop in luminous flux. In addition, the component has been tested for a long time under high-temperature, high-humidity conditions similar to saunas, and it has also been confirmed that LEDs are not adversely affected.
This new LED is ideal for linear and regional lighting fixtures found in office, store and billboard lighting solutions. The Duris P5 achieves uniform illumination without any noticeable spots. Since lighting fixtures typically contain more than 100 medium power LEDs, the LEDs used must have low failure rates.
The high corrosion resistance of the Duris P5 is not only an important factor for outdoor applications. LEDs are also subject to corrosive substances in indoor applications, including corrosion from circuit board materials, rubber seals or adhesives. Therefore, the increased corrosion resistance provides an additional guarantee for the durability of professional lighting solutions.

OSRAM Opto Semiconductors has introduced the Duris P5 LED component, which offers up to 110 lm/W (3000K color temperature) with an average lifetime of over 50,000 hours, even at high currents and temperatures. In addition, this energy-efficient LED component is the first of its kind in the mid-power applications market and is especially suitable for use in harsh environmental conditions. Osram says it has the lowest failure rate during long-term use.
