Osram OS Adds New High CRI Duris E5 for Professional Indoor Lighting Applications

Osram Opto Semiconductors presents a new Duris E5 with a significantly improved efficacy of more than 130 lm/W compared to the current version. A high color rendering index (CRI) of more than 90 and typically 95 enables high quality lighting solutions in shops or museums. Due to the same footprint and other common features the new mid-power LED can replace the current product versions very easily.

The new Duris E5 (GW JDSRS1.CC) will complement the well-known Duris product family of Osram Opto Semiconductors by mid of January 2015. With an improved efficacy of 131 lm/W at 4000 K and 120 mA it can perfectly be used for energy saving lighting applications. Furthermore, the new mid-power LED features an improved thermal conductivity as well as lower forward voltage (3.00 V at 120 mA). The optics are absolutely compatible to all members of the Duris family and the platform design is the same, so customers can replace the current LED versions easily.

The good color rendering of typically 95 makes the new Duris E5 ideal for applications in which the requirements for good quality of light are particularly high, e. g. professional lighting solutions in shops or museums, but they can also be used for non-directional indoor LED retrofits. The well-known package offers great design flexibility for the customers and facilitates the replacement of previous product versions, too.

The new LED is available with different color temperatures from 2700 to 4000 Kelvin (K). The certification process for the high lifetime standard of LM-80 is already under way and will be finished by early 2015.

For more information on the Osram Duris family and other LEDs for general lighting see the Osram OS Duris E5 product catalog.
