ams OSRAM GW QTLQS1.LM DURIS® E 2835 High-Efficiency 3V White LED

Introduction

The ams OSRAM DURIS® E 2835 (GW QTLQS1.LM) is an industry-standard mid-power LED designed for manufacturers who require a balance of high radiant power and proven industrial reliability. Built on a robust lead-frame platform, this LED handles the thermal demands of high-density PCB arrays. The GW QTLQS1.LM is specifically binned for manufacturers of office troffers, linear industrial fixtures, and edge-lit panels who prioritize efficacy (lm/W) and long-term chromaticity stability.

For LED module manufacturers and contract manufacturers (EMS), the GW QTLQS1.LM offers a low-risk design path in the standardized 2835 footprint. Its optimized electrical characteristics allow engineers to simplify driver selection and circuit layout, effectively lowering the overall system Bill of Materials (BOM) without compromising on the quality of light.

Key Product Features

• Exceptional Luminous Efficacy: Optimized for high-output performance at a nominal 100mA drive current, allowing fixture manufacturers to meet strict Energy Star® or DLC® efficacy standards with a lower component count.
• 1/9th Micro-Binning Support: Utilizing ams OSRAM's precision binning technology, this SKU ensures color coordinates fall within a very tight space. This effectively eliminates visible "checkerboard" effects in large open-plan office installations.
• Industrial-Grade Lead-Frame Durability: Featuring a junction-to-solder point thermal resistance optimized for mid-power stability, the DURIS® E 2835 series protects the phosphor layer from premature yellowing in 24/7 commercial environments.
• Proven Reliability for B2B Supply: Backed by extensive LM-80 data, this component supports the long-term warranties required for municipal roadway and professional commercial project tenders.
• SMT Production Yield: Designed for high-speed automated pick-and-place lines, the component features consistent wetting properties during reflow, ensuring stable production yields for high-volume factories.

The DURIS® E 2835 GW QTLQS1.LM is a staple light source for:

• Professional Office Troffers: High-efficacy LED panel lights and recessed fixtures where color uniformity across large ceiling grids is critical.
• Industrial High-Bay & Low-Bay: Consistent light engines for warehouses and factory floors requiring daylight contrast and alertness.
• Linear Accent Lighting: High-density LED strips for architectural coves and furniture modules where the 2835 footprint allows for seamless integration.
• Specialty Edge-Lit Backlighting: Uniform white light for informational signage and advertising panels.
