Fluence SPYDR 2r LED Grow Light — 47in PhysioSpec™ Broad R4, 1600 µmol/s, 120-277V

Craft-Grade Power and Precision for the Serious Indoor Cultivator

The Fluence SPYDR 2r LED Grow Light is a high-performance 47-inch top-light fixture purpose-built for craft herb cultivators and serious indoor growing operations demanding both power and precision. With a 1,600 µmol/s PPF output, PhysioSpec™ Broad R4 spectrum, and a wide 120° light distribution angle, the SPYDR 2r delivers intense, uniform photon coverage across the canopy — optimizing every grow cycle for maximum yield and quality in the hands of growers who know what their plants need.

Unlike the standard SPYDR 2 variants, the SPYDR 2r ships as a complete self-contained system with an integrated 120–277V AC power supply unit and a 0–100% dimmer for full light intensity control from day one. With a 2.6 µmol/J efficacy rating at 240V AC, IP66 environmental protection, and a 5-year warranty backed by UL 8800 and UL 1598 certifications, the SPYDR 2r is engineered to deliver at the highest level across more than 36,000 hours of rated lifetime operation.

Key Features & Benefits

• 1,600 µmol/s PPF Output: Delivers intense photon flux density across the full canopy footprint — providing the light energy micro-growers and craft cultivators need to drive vigorous growth, dense flowering, and high-quality harvests.
• 0–100% Integrated Dimmer: Precise light intensity control from 0 to full output enables targeted lighting adjustments at every growth stage — from early vegetative light levels through peak flowering intensity — without external control hardware.
• 2.6 µmol/J Efficacy @ 240V AC: Industry-competitive photon efficacy rating means the SPYDR 2r delivers more usable light per watt of electricity consumed, reducing energy costs relative to output in any production environment.
• 120–277V AC Power Supply — Wide Voltage Compatibility: The 626W integrated power supply accepts 120–277V AC, 50/60 Hz input, making the SPYDR 2r compatible with a broad range of North American and international grow facility electrical configurations.
• IP66 Sealed Enclosure: Dust-tight and high-pressure water-jet resistant construction ensures reliable operation in the high-humidity, high-moisture conditions of professional indoor growing environments across the full fixture lifetime.
• UL 8800, UL 1598 & CE Certified — 5-Year Warranty: Meets leading horticultural lighting safety standards with a 5-year warranty, providing commercial-grade assurance for craft and professional grow operations investing in long-term lighting infrastructure.

Who Should Use This

The Fluence SPYDR 2r is the ideal LED top-light solution for craft herb cultivators, micro-growers, and indoor growing operations that want the precision, power output, and build quality of Fluence's professional LED platform in a self-contained, ready-to-deploy system. It is particularly well-suited for operators who demand full dimmer control and wide voltage compatibility without additional controller hardware investment.

Frequently Asked Questions

What is included with the SPYDR 2r?

The SPYDR 2r ships as a complete system including the 47-inch light bar and integrated 120–277V AC power supply unit with 0–100% dimmer. An AC cord and DC extension cable are sold separately and must be purchased to complete the installation.

Why is this fixture specifically recommended for craft cultivators?

The SPYDR 2r's 1,600 µmol/s PPF output, integrated dimmer, and precise control over light intensity at every growth stage make it well-suited for cultivators who actively manage their light environment throughout the crop cycle — a hallmark of craft cultivation practice focused on quality, expression, and yield optimization.

What is the recommended mounting height for the SPYDR 2r?

Fluence recommends mounting the SPYDR 2r 6–12 inches above the canopy. Actual optimal height depends on your grow configuration, canopy density, and target PPFD level at the canopy surface.

What dimming interface does the SPYDR 2r use?

The SPYDR 2r uses M12 connectors with a 0-10V signal for dimming, with dim-to-off capability across the full 0–100% range. Compatible with standard 0-10V grow light dimmer controllers including the Fluence SHYFT Light Scheduler.

What is the IP66 rating and why does it matter for grow rooms?

IP66 means the fixture is both dust-tight and protected against high-pressure water jets — providing robust protection against irrigation spray, high-humidity condensation, and the spray cleaning protocols standard in commercial indoor growing facilities. This ensures the SPYDR 2r operates reliably across its full rated lifetime in demanding grow environments.
