Introducing the DURIS® E 2835 0.2 W SOFTLINEAR LED by ams OSRAM

The new DURIS® E 2835 LEDs from ams OSRAM introduce engineering innovations all the way from the package to the emitter. These innovative LEDs boast a specially designed lead frame and improved reliability in the field—and their reduced resistance to bending facilitates their integration into flexible strips.

  • ams OSRAM proudly presents the DURIS® E 2835 LED, a revolutionary advancement in lighting technology. Engineered from the package to the emitter, these LEDs feature a specially designed leadframe that enhances durability and flexibility in lighting strips, ensuring superior performance and extended reliability.
  • With a high colour rendering index (CRI) of up to 97, the DURIS® E 2835 is ideal for applications requiring accurate and vivid colour representation, such as retail displays and museums. The compact design and high luminous efficacy of 135 lm/W at 3000K make it perfect for space-constrained environments.
  • Offering a range of colour temperatures and robust electrostatic discharge protection, the DURIS® E 2835 is versatile enough for indoor, architectural, and waterproof lighting applications.

In addition, a 2400 Kelvin CCT option compensates for the effects of the silicone encapsulant in waterproof applications such as swimming pool or garden pond lighting to achieve a Correlated Color Temperature (CCT) of 3000 Kelvin when completed. The new LEDs also feature a particularly high Color Rendering Index (CRI) of 97, making them ideal for retail-display lighting, museums, and retail premises. This pre-molded PPA 2835 LED, with its standard 2835 footprint, offers exceptional value on both the application and system levels.

Key Features

Compact and durable design

  • The DURIS® E 2835 measures just 2.8 mm x 3.5 mm, making it ideal for applications where space is at a premium.
  • The robust design can withstand the rigors of flexible strip installations without failing.

Luminous efficiency

  • At 3000 Kelvin (CRI 90), the DURIS® E 2835 delivers a typical luminous flux of 23.5 lumens and an efficacy of 135 lm/W, making it highly efficient and powerful.

High CRI

  • Offering a Color Rendering Index (CRI) of 90 (min.) and 92 (typ.), with an impressive R9 value of 50 (min.), this LED ensures colors are rendered accurately and vividly. Thanks to ams OSRAM’s proprietary tuning process, we can also offer a CRI value of 97 (min.), surpassing the industry standard of 95.

Versatile color temperatures

  • Available in a color temperature range from, 2200 Kelvin to 6500 Kelvin this LED can cater to diverse lighting needs, from warm, cozy environments to cool, bright settings.

Wide beam angle

  • With a typical radiation angle of 120° (Lambertian emitter), the DURIS® E 2835 provides wide and uniform light distribution, which is simply perfect for general lighting applications.

Longevity and reliability

  • The DURIS® E 2835 boasts a lifetime of up to 36,000 hours at lumen maintenance of 90%, ensuring long-term performance and reduced maintenance costs.

Electrostatic discharge (ESD) protection

  • With a 2 kV ESD rating in accordance with ANSI/ESDA/JEDEC JS-001 (HBM, Class 2), this LED is safeguarded against electrostatic damage, enhancing its reliability in various applications.


Indoor lighting
The DURIS® E 2835 is an excellent choice for indoor lighting applications, offering superior CRI value for true-to-life color rendering, making it ideal for residential, commercial, and retail environments where light quality is of paramount importance.

Architectural lighting
The flexibility of the DURIS® E 2835 0.2 W SOFTLINEAR makes it suitable for architectural lighting, allowing for creative and intricate designs. Whether highlighting architectural features or creating ambient effects, this LED can transform spaces with its versatile lighting capabilities.

Flexibility and innovation
With its innovative lead frame, engineered for superior flexibility, the DURIS® E 2835 0.2 W SOFTLINEAR endures where conventional LEDs can fail when mounted on flexible strips. By using an advanced lead frame material and a carefully designed structure, the DURIS® E 2835 0.2 W SOFTLINEAR is less resistant to bending in flexible lighting applications. This eliminates a major limitation of previous LED strip designs and opens up new possibilities for creative and practical lighting solutions.

Waterproof capabilities
For applications requiring waterproof strip lighting, the DURIS® E 2835 0.2 W SOFTLINEAR is available with a Correlated Color Temperature (CCT) of 2400 Kelvin to compensate for the optical effects of silicone encapsulant. This makes it ideal for use in bathrooms, kitchens, or swimming pools, garden ponds, and other outdoor applications that may be permanently immersed or periodically exposed to high humidity. This CCT pre-compensation allows lighting installations set up with DURIS® E 2835 emitters to be more easily designed to meet specific application purposes.

The DURIS® E 2835 0.2 W SOFTLINEAR from ams OSRAM is a versatile, high-performance LED designed to meet the evolving demands of modern lighting applications. Its compact size, high CRI, luminous efficacy, and innovative flexibility make it an exceptional choice for a wide range of uses. Whether for indoor, architectural, or semi-outdoor lighting, the DURIS® E 2835 delivers reliability, efficiency, and superior lighting quality, setting a new standard in LED technology.
