ams OSRAM DURIS® S 8 Far Red GF PUBRA1.25 High-Efficacy 730nm Horticulture LED

Introduction

The ams OSRAM DURIS® S 8 GF PUBRA1.25 is a professional-grade Far Red LED engineered specifically for Controlled Environment Agriculture (CEA). Operating at the critical peak wavelength of 730 nm, this component is the industry standard for managing plant photoperiodism and triggering the "Emerson Effect." Unlike standard LEDs binned for human vision, the GF PUBRA1.25 is characterized by its Photosynthetic Photon Flux (PPF) at 85°C, ensuring that LED module manufacturers can design high-PPE fixtures with predictable performance under real-world greenhouse heat.

By utilizing the integrated multi-die 5050 platform, ams OSRAM provides a tactical advantage in both radiant intensity and cost. This series allows fixture manufacturers to reduce the total SMT placement count while achieving the high-density far-red peaks required for advanced spectral recipes in commercial greenhouses and vertical farms.

Key Product Features

• Precise 730nm Spectral Output: Optimized for the Pfr (Phytochrome Far-Red) absorption peak. This precision ensures consistent control over flowering cycles and the "shade avoidance response," critical for uniform crop morphology.
• Verified 85°C Hot-Binning: Characterized at realistic fixture operating temperatures. This eliminates the performance gap common in budget emitters binned at 25°C, ensuring spectral ratios remain stable once the fixture reaches thermal equilibrium.
• Industrial-Grade Lead-Frame Reliability: The robust 5050 package handles high power densities with an optimized thermal path. This facilitates efficient heat transfer to the MCPCB, preserving the L70/L90 lifespan required for 5-year commercial warranties.
• High-Voltage Design for System BOM Efficiency: Operating on a higher voltage class, the GF PUBRA1.25 allows for lower current throughput from the driver. This reduces resistive heat losses across the PCB and facilitates the use of more cost-effective LED drivers.
• Sulfurization Resistance: Built with automotive-grade materials, this series is designed to withstand the harsh environments of indoor farming, where humidity and fertilizers can corrode standard components.

The DURIS® S 8 GF PUBRA1.25 is the staple far-red light source for:

• Greenhouse "End of Day" (EOD) Lighting: Triggering rapid conversion of phytochrome to accelerate the flowering process in short-day crops.
• Multi-Spectral Top-Lighting: Combined with Deep Red (660nm) and Royal Blue (450nm) to maximize the Emerson Effect and improve total photosynthetic rate.
• Medicinal Cannabis Cultivation: High-intensity Far Red pulse treatments to manipulate terpene profiles and flower structure.
• Horticultural Research & Lab Cabinets: Calibrated 730nm sources for precision plant physiological studies and controlled growth trials.
