Achieve high-efficiency indoor growth with 1600 µmol/s output and full-spectrum control for premium bud cultivation.

The Fluence SPYDR 2r LED Grow Light delivers precision, efficiency, and control for craft herb cultivators and micro-growers. With a PPF output of 1600 µmol/s and PhysioSpec Broad R4 spectrum, it replicates natural sunlight to support full-cycle growth from veg to flower. Designed for canopy-uniform lighting in stacked or open-room setups, the SPYDR 2r ensures every plant receives consistent light intensity for optimal yields and quality. A 0–100% dimmer allows growers to fine-tune output across different stages of cultivation with unmatched precision.

Is the Fluence SPYDR 2r energy-efficient?

Yes. The SPYDR 2r operates at 2.6 µmol/J, significantly outperforming traditional 1000W HPS fixtures (≈1.7 µmol/J). That means you get more usable PAR light per watt while drawing only 626W at 240V AC. Lower power consumption, reduced heat, and higher yield efficiency make it a cornerstone for any energy-conscious grow operation.

Mounting Hardware Options:

  • Lance Hangers: Standard option included with every SPYDR 2r. Offers a 2-point hanging setup (customer supplies rope ratchets, chain, or cable). Ensure the PSE is centered for proper balance. Best for non-rack installations.
  • Adjustable Hanging Kit: 2-point hanging system with 5 ft braided stainless-steel wires and carabiners. PSE must be centered for balance.
  • Short “V” Mounting Brackets: 4-point mounting setup ideal for waterfall decking on 2"–3.5" support beams (rolling or some pallet racks).
  • Long “V” Mounting Brackets: 4-point mounting setup designed for waterfall decking on 4"–5" support beams (pallet racks).
  • Solid Decking Mounting Brackets: 4-point mounting setup for solid decking and rolling tables. Requires two front-to-back support bars per fixture.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
