Description
  • 2026 Updated Version: The SF4000 has been upgraded with Premium Bridgelux high-efficiency LEDs offering the same output, uniformity, and reliable performance without any alteration.

  • Efficiency and Coverage: With PPE: 2.7 µmol/J and Coverage measuring 4'X4', it's suitable for a 4'X4' grow tent. For optimal ventilation, a 6-Inch fan is recommended.

  • Top Features: The 2026 new SF4000 is designed with upgraded high-performance Bridgelux LEDs, providing strong, uniform light output with excellent canopy penetration. The increased diode count and optimized layout ensure consistent light efficacy, PPF output, and uniformity as in the earlier Samsung-based version for reliable yields.

  • Advanced Diodes and Dimming Design: The SF Series features high-performance Bridgelux diodes with an increased count to reduce stress, improve thermal stability, and extend lifespan. It comes with a dimming knob, which allows adjustment of light intensity as desired. This feature, coupled with unified dimming, proves to be beneficial in large indoor growing and commercial planting areas.

  • Suitable for All Growth Stages: The full spectrum light features white, blue, red, and IR (3000K, 5000K, 660nm and IR 760nm). The 3000K, full of more reddish light, and the 5000K diodes, which provide more blueish light, are especially useful in the blooming stage as they speed up flowering time and enhance yields. Turn your seeds into your own supply.

  • Durable and Quiet: The SF4000 produces no fan noise and comes with a branded high safety performance driver with good quality waterproofing. The updated aluminum material is thick and sturdy, emitting minimal heat and includes high-quality protective covers for cables. The light lasts longer and saves you money.

  • Professional Manufacturer: With more than a decade of experience manufacturing LED grow lights, Spider Farmer strives to create efficient, high-quality home planting equipment and to become a trusted partner for every planter! The Spider Farmer SF4000 grow light includes an instruction manual, a pair of silver hooks, and a pair of black hangers.
