Frequently Asked Questions

What is PhysioSpec™ BROAD R4 (Indoor) spectrum?

PhysioSpec™ BROAD R4 (Indoor) is Fluence's scientifically developed spectral output for indoor crop production. It provides continuous photon emission across the 400–700nm PAR range, formulated to balance photosynthetic efficiency with the crop quality and yield outcomes specific to controlled environment indoor horticulture.

What is the difference between the SPYDR 2h, 2i, and 2x?

The SPYDR 2h, 2i, and 2x are variants within the SPYDR 2 platform, each offering the same PhysioSpec™ BROAD R4 (Indoor) spectrum in a 47-inch top-light form factor. The primary differences are the power supply voltage class (HVG for 2h; LVG for 2i and 2x) and the corresponding power output and electrical characteristics suited to different facility infrastructure requirements.

What mounting height is recommended for the SPYDR 2I?

Optimal mounting height depends on your target PPFD, canopy coverage area, and crop type. Fluence provides fixture-specific mounting height and spacing recommendations — consult Fluence's lighting layout resources or your Fluence representative for facility-specific guidance.

Does the SPYDR 2I support dimming?

Yes — Fluence SPYDR 2 fixtures support dimming control. Compatible dimming solutions include 0-10V signal controllers. Refer to Fluence's dimming cable and controller documentation for connection specifications.

Is the SPYDR 2I suitable for both vegetative and flowering stages?

Yes — the PhysioSpec™ BROAD R4 (Indoor) spectrum is optimized to support plant development across all growth stages, from vegetative through flowering and finishing, making it a versatile full-cycle top-light solution for commercial indoor growing operations.
