About the Spider Farmer SF4000

  • LOWER RUNNING COSTS & HIGHER-QUALITY YIELDS: Spider Farmer LED Grow Lights utilize the latest high yielding LED technology using Samsung LM301B diodes, giving it a high energy efficiency of 2.9 umol/J. SF4000 only consumes 450w, running 50% less power than the HPS or Blurple lamps, and still was 50% more harvest. The optimal veg footprint is 5 x 5 ft, and the flowering footprint is 4 x 4 ft.
  • CUSTOMIZED DIMMING DESIGN: Upgraded SF series growing lights have a dimming knob and light switch. A single light can be adjusted the light intensity at liberty. Multi-light Connection with unified dimming especially beneficial for large areas of indoor growing and commercial planting. 
  • IDEAL FOR ALL GROWTH STAGES: Excellent full-spectrum - white, blue, red, and IR (3000K, 5000K, 660nm, and IR 760nm). 3000K diodes providing more reddish light and the 5000K providing more blueish. The 660nm red and IR light is especially useful during bloom, where it speeds up flowering time and boost yields. Turn your seeds into your own supply. And the light looks fairly natural, so it's good for accurately monitoring plant health.
  • SOLID & STURDY: No Fan Noise Free. High Safety performance MEAN WELL Driver, Fair Waterproofing. Update aluminum board is thick and sturdy, doesn't put out a tremendous amount of heat, high-quality protective covers for cables; User-Friendly Packaging. Quality components mean the light lasts longer, but they also save you money. 
  • VALUE FOR THE MONEY: Spider Farmer LED Plant Lights are often copied but will never have our quality or commitment, we provide 3 years of after-service at one of our US local maintenance center.
