ams OSRAM DURIS S 8 Deep Blue GD PUBRA1.15 High-PPE 450nm Horticulture LED

Introduction

The ams OSRAM DURIS® S 8 GD PUBRA1.15 is a professional-grade Deep Blue LED engineered specifically for Controlled Environment Agriculture (CEA) and high-intensity industrial sensing. Operating at a peak wavelength of 450 nm, this component targets the primary absorption peaks of Chlorophyll B, which is essential for healthy vegetative growth and plant morphology. Unlike standard industrial LEDs, the GD PUBRA1.15 is characterized by its Photosynthetic Photon Flux (PPF) at 85°C, ensuring that LED module manufacturers can design high-PPE fixtures with predictable results under real-world greenhouse heat.

By utilizing the integrated multi-die 5050 platform, ams OSRAM provides a tactical advantage in thermal management. The increased lead-frame surface area facilitates rapid heat transfer, preventing the radiant flux drop and wavelength shift common in smaller 3535 or 2835 emitters when driven at high current densities.

Key Product Features

• Optimized 450nm Spectral Purity: Engineered for maximum Photosynthetic Photon Efficacy (PPE). It provides the intense blue energy needed for compact plant growth and strong stem development.
• High-Voltage Design for System Efficiency: Operating on a higher voltage tier (~18V class) allows for lower current throughput from the driver. This reduces I2R resistive heat losses across the PCB and simplifies the overall Bill of Materials (BOM).
• Industrial-Grade Lead-Frame Reliability: The robust 5050 package is built for 24/7 industrial use. Its material set is optimized to resist sulfurization and thermal fatigue, preserving the L70/L90 lifespan required for commercial farming contracts.
• Verified 85°C Hot-Binning: Characterized at realistic fixture operating temperatures. This eliminates the performance gap found in budget LEDs binned at 25°C, ensuring consistent spectral ratios across large-scale greenhouse arrays.
• Precision Optical Distribution: The 120-degree Lambertian viewing angle is perfectly matched for standard reflectors and wide-area diffusion, facilitating uniform PPFD distribution across the plant canopy.

The DURIS® S 8 GD PUBRA1.15 is a staple light source for:

• Vertical Farming Top-Lighting: High-density blue peak source for leafy greens and microgreens requiring compact morphology.
• Greenhouse Supplemental Lighting: Boosting the essential blue spectrum during low-sunlight periods to enhance plant pigmentation and nutrient value.
• Medicinal Cannabis Cultivation: Primary blue engine for multi-spectral arrays requiring high PPFD during the vegetative phase.
• Industrial UV/Blue Curing: Durable 450nm emitter for specialized industrial printing and high-speed adhesive polymerization.
