The Spider Farmer® SF4000 Dimmable LED Grow Light is a high-performance, wide-format quantum board style LED fixture engineered for larger grow tents, commercial multi-tier setups, and expansive vegetative or flowering spaces. Operating at a true power draw of 450 watts, this robust fixture generates an impressive photon flux output designed as an energy-efficient replacement for traditional 600W–800W single-ended HID lamps. It provides uniform PAR distribution, deep canopy penetration, and balanced photon density across a 5' x 5' vegetative or 4' x 4' flowering footprint.

 

Key Features

• High-Output Quantum Board: Delivers exceptional photon flux density with high system efficacy to maximize PAR per watt consumed while lowering electric bills.

 

• 600W–800W HID Replacement: Consumes only 450W of real power while matching or exceeding the light intensity of legacy 600W–800W metal halide or HPS systems.

 

• Sunlike Full Spectrum: Integrates Samsung LM301B/LM301H white LEDs with Osram 660nm deep red LEDs for complete seed-to-harvest plant development.

 

• Uniform 4x4 Canopy Coverage: Wide board layout provides balanced, edge-to-edge photon distribution across 5' × 5' vegetative or 4' × 4' flowering areas without hot spots.

 

• Silent Passive Thermal Dissipation: Heavy-duty aluminum heat sink base eliminates mechanical cooling fans entirely (0 dB operation) for silent grow room environments.

 

• Moisture-Resistant Protection: Diodes feature a protective conformal coating (water/dust resistant) to withstand humid micro-climates inside enclosed grow tents.

 

• Onboard Dimmer & Daisy Chain: Features a built-in dimmer knob (10%–100%) and multi-light synchronization ports to connect multiple units in larger cultivation spaces.

 

Equipped with high-performance Samsung LM301B/LM301H white diodes and Osram 660nm deep red chips mounted across a wide aluminum board layout, the SF4000 emits a sunlike full spectrum optimized to drive heavy yields and terpene production. Built with a thick aluminum passive heat sink base plate for silent fanless thermal dissipation, protective conformal coating against humidity and moisture, an onboard dimmer box, and daisy-chain capability, it offers commercial-grade intensity control for serious home growers and cultivators.
