ams OSRAM DURIS® S 8 GW Q9LR34.EM High-Voltage 5050 LED

Introduction

The ams OSRAM DURIS® S 8 (GW Q9LR34.EM) is a professional-grade mid-power LED integrated in a robust 5050 footprint. It is engineered for manufacturers who require intense radiant power and superior system-level efficiency. By utilizing a high-voltage, low-current architecture, this series provides LED module manufacturers a reliable path to reducing resistive heat losses across the PCB traces and facilitates the use of more cost-effective, high-efficiency non-isolated drivers.

For luminaire designers and distributors, the GW Q9LR34.EM series addresses the critical challenge of maintaining optical uniformity in high-wattage arrays. Built on a proven lead-frame platform, these emitters handle high power densities while ensuring that target chromaticity and lumen maintenance are preserved throughout the fixture's rated industrial lifespan.

Key Product Features

• Optimized High-Voltage Performance: By operating at a higher voltage tier (~24V), the DURIS® S 8 reduces the output current required from the LED driver. This allows for thinner copper traces on the PCB and improves the overall driver conversion efficiency, effectively lowering the system Bill of Materials (BOM).
• Verified Hot-Color Targeting at 85 °C: Unlike budget-grade LEDs rated only at 25 °C, ams OSRAM bins this series at actual operating temperatures. This ensures that the light quality specified during the design phase matches the actual performance once the fixture reaches thermal equilibrium on-site.
• Industrial-Grade Lead-Frame Durability: The specialized 5050 package is designed to withstand extreme thermal cycling and high-humidity environments. This stability protects the phosphor layer from premature yellowing, ensuring CCT consistency.
• Excellent Sulfur Resistance: Built with high-quality plating and materials, the DURIS® S 8 series is designed to withstand harsh industrial gases, a non-negotiable factor for municipal roadway tenders and high-bay fixtures in high-pollution zones.
• Precision Binning Consistency: Binned within a 3-step MacAdam ellipse, the GW Q9LR34.EM ensures that color variance across large-scale installations is virtually invisible to the human eye.

The GW Q9LR34.EM series is a staple light source for performance-driven markets:

• Industrial High-Bay & Low-Bay: Consistent, high-intensity daylight white sources for warehouses requiring high alertness and visibility.
• Municipal Street Lighting: High-throw efficacy for roadway infrastructure projects targeting Energy Star® or high maintenance cycle certifications.
• Parking Lot & Area Floodlighting: Durable emitters for wall packs and security floodlights targeting high lumens-per-watt and resistance to environmental stress.
• Office Troffers & Linear Fixtures: High-lumen density modules where higher voltage strings help in achieving slim-profile driver integration.
