Exclusive Limited Time Offer: GrowAce.com customers will receive a FREE pair of Yield Lab LED grow room glasses with the purchase of the Spider Farmer SF4000 LED Grow Light System ($29.95 value!)


The Spider Farmer SF4000 grow light is an energy-efficient LED as its par efficacy is reported at 2.7 umol/J. The SF4000 LED grow is equivalent to 1000 watt single-ended HID fixture. Each light fixture consists of 1152 Samsung LM301B LED chips,4 IR chips, 56 Deep Red LED chips. The LED emits full-spectrum white light (3000K, 5000K, 660-665nm, 760nm), which imitates sun-like properties and boosts plant growth.

  • Aluminum Heat Sink: Aluminium has excellent thermal conductivity properties, which allow quick heat dispersion and also help increase the intensity of light up to 20%.

  • Sun-Like Spectrum: With the full-spectrum white light, consisting of the color temperatures:3000K, 5000K, 660-665nm, 760nm. It ensures that your plants get nourished just the way they would have under natural sunlight.

  • Samsung LM301B Diodes: These LEDs ensure deeper canopy light penetration, and you can expect to get 40% higher yields with very less energy consumption. These diodes are the best available in the market.

  • Dimmable Meanwell Driver:With the Meanwell dimmable drivers, you can take control of the energy consumption of the grow light system, improve light efficacy, adjust current amplitude, save power consumption costs.

The Spider Farmer SF4000 LED gives a full spectrum white-light which imitates the sun-like properties to which plants respond in a similar way they would have to the natural sunlight. Therefore, the plants get full-nourishment even when placed indoors.

3000K (WarmWhite Light): Helps grow the flower size.

5000K (Blue Light): Boosts the plant growth rate, boosts germination.

660nm (Red Light): When used in combination with blue light it yields more leaves.

760nm (IR Light): Promotes higher yields by speeding up the phytochrome conversion process.

The quantum board is embedded with the Samsung LM301B Diodes, which allows better canopy penetration to promote photosynthesis in plants. When mounted at 24” height, its flower footprint is 4' x 4' or 5' x 5' and at 36” height its vegetative footprint is 6' x 6' area.

The fixture utilizes the passive heat management system to maintain the temperature of the fixture. Due to the absence of cooling fans in the system, the heat dissipation process is carried out noiselessly. The Meanwell heatsink is made out of aluminum as the metal possesses high thermal conductivity properties- which helps in getting rid of the heat more rapidly.

The led light consists of 4 infrared chips (IR). Exposing plants to the infrared red rays helps improve the quality of buds, promotes stem growth, and shortens the growth cycle, for getting quick results.

With the dimmer, you can control the amount of energy being consumed, control the grow light system, improve the light efficacy, make adjustments with the current amplitude, hence save the power consumption costs.

The LED grow light is recommended for grow tents, grow rooms, large indoor grows, vegetative growth, and supporting plants at every stage of their growth cycle. The LED grow light fully supports hydroponic, aeroponic, or aquaponic systems. The SF4000 LED Grow Light System is ideal for growers worldwide.

Blindingly Bright

Winter night growing hardly have to exhaust heat. Kept warm during day (lights off) with waterbed heater. At 68° will allow to get the purple phenotypes. Blindingly bright.
