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

A Complete, Self-Contained Lighting System With Built-In Dimming Control

The Fluence SPYDR 2r is a 47in LED fixture that ships as a complete, ready-to-power system: an integrated 120-277V AC power supply and a 0-100% onboard dimmer are built into the unit itself, so there is no separate driver box to mount and no external dimmer controller required just to adjust output. It runs the PhysioSpec Broad R4 spectrum and is rated for 1,600 µmol/s of photosynthetic photon flux, aimed at operators who want strong output and direct intensity control from a single fixture.

At 626W and a 2.6 µmol/J efficacy rating measured at 240V AC, the SPYDR 2r pairs its self-contained design with an IP66 enclosure rated for dust and high-pressure water-jet exposure, and Fluence backs it with a 5-year warranty across a rated lifetime beyond 36,000 hours.

Key Features & Benefits

• Integrated 0-100% Dimmer: Adjust output directly at the fixture from full off to full intensity, without buying or wiring a separate controller.
• 1,600 µmol/s PPF Output: Delivers substantial photon flux across the full 47in footprint for dense canopy layouts.
• Self-Contained 120-277V AC Power Supply: The onboard PSU accepts a wide AC voltage range at 50/60Hz, so there is no separate driver enclosure to install.
• IP66 Enclosure: Sealed against dust ingress and high-pressure water jets for washdown-capable grow spaces.
• 5-Year Warranty, >36,000hr L90: Backed by UL 8800 and UL 1598 certification for long-cycle commercial deployment.

Who Should Use This

Cultivators who want fixture-level dimming without adding a separate control unit, and who are deploying a single fixture or a small run rather than a large zone-managed array, are the direct fit for the SPYDR 2r. Mounting height of 6-12in above canopy is recommended; an AC cord and DC extension cable are sold separately to complete the installation.

Frequently Asked Questions

What comes included with the SPYDR 2r versus purchased separately?

The 47in light bar and its integrated 120-277V AC power supply with built-in 0-100% dimmer are included as one unit. An AC cord and a DC extension cable are both sold separately and are needed to complete a working installation.

How is the SPYDR 2r different from needing a separate dimmer controller?

Other Fluence fixtures typically dim through an external unit such as the Whisper 2.0 Dimmer or a PSE/PSU controller wired in-line. The SPYDR 2r builds that 0-100% dimming function directly into the fixture, so a single unit handles both light output and intensity adjustment.

What mounting height does Fluence recommend for the SPYDR 2r?

Fluence recommends mounting 6-12in above the canopy, with the exact height depending on canopy density and the target photon flux density at the leaf surface. Growers should adjust within that range based on observed plant response.

Does the IP66 rating mean the SPYDR 2r can be pressure-washed?

IP66 confirms protection against dust ingress and high-pressure water jets from any direction, which covers routine washdown cleaning protocols common in commercial grow spaces. Always follow Fluence's cleaning guidance rather than assuming any cleaning method is safe by default.
