Top Features

  • LOWER RUNNING COSTS & HIGHER-QUALITY YIELDS: SPIDER FARMER SF4000 Grow Lights utilize the latest in high-yielding LEDs technology today-Samsung LM301B diodes, high Energy Efficiency with 2.7 umol/J, create better canopy light penetration. SF4000 only consumes 450w, running 50% less power than the HPS or Blurple lamps, and still was 50% more harvest. The veg footprint is 5 x 5 ft, 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 to the light intensity at liberty. Multi-light Connection with unified dimming is 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 provide more reddish light and 5000K provides more blueish. The 660nm red and IR light is especially useful during bloom, where it speeds up flowering time and boosts yields. Turn your seeds into your own supply. And the light looks fairly natural, so it’s good for accurately monitoring plant health.
  • WELL MADE & SOLID CONSTRUCTION: 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 5 years of after-service of local maintenance center(US/CA/UK/DE/AU). Make sure you purchase authentic Spider Farmer grow lights, which really can give you a need from high-quality grow lights – at a price that is affordable. For any questions, feel free to e-mail us and we will help you resolve them. Quality backed by our ironclad!!!

Warm Tips:

1.Do NOT touch while in operation.

2.To prevent eye damage, avoid looking directly at the LEDs.

3.In summer or other hot environments, please use a cooling fan to keep a suitable temperature for your plants.

    BigTcaregiving – October 4, 2021

    So I run a perpetual harvest as a caregiver and we harvest every week. We are currently using HPS in our flowering rooms and dual spectrum in our veg T fives over clones. I purchased a 10 x 10 tent and to SF 4000 spider farmer lights. So far I am pretty happy I’m only going to run them on half the 10th feeling that I need to have another two to be able to cover the other half of the tent properly. I only gave it four stars because when I’m boxing the first package both of my Meanwell ballasts I had been knocked off the back of the board and had to be re-screwed back on but I believe that had more to do with shipping then spider farmer as their packaging was very nice. The lights are significantly brighter than I thought they would be and I am a little skeptical on how many plants you can put under one of these lights so I will be placing one plant under one light and five plants under the other as soon as I can afford it I will be ordering two more lights really hoping to be able to replace my large room with these LEDs when it’s all said and done. I am also looking forward to ordering the control board I currently use something similar with my HPS system and nanolux
