  • Cutting-Edge LED Chips for Unrivaled Performance：Introducing the Samsung LM301H EVO LEDs. Boasting an impressive efficiency rating of 3.14 µmol/J PPE per diode , these LEDs outshine even the renowned LM301B, LM301H, and Bridgelux 3030 chips in terms of sheer effectiveness. Representing the pinnacle of horticulture lighting technology, they radiate unparalleled brilliance while operating at heightened efficiency levels. Surpassing the capabilities of both the Samsung LM301H and LM301B LEDs, these EVO LEDs redefine plant growth enhancement. With superior light quality and an increased light output per LED, they harness a more potent blue spectrum, all while achieving a level of efficiency unattainable by non-EVO LEDs. Veg footprint is 5 x 5 ft, Flowering footprint is 4 x 4 ft.
  • IDEAL FOR ALL GROWTH STAGES: With excellent full spectrum light – white, blue, red and IR (3000K, 5000K, 660nm and IR 760nm), the 3000K diodes provide more reddish light and the 5000K diodes provide more blueish light. The 660nm red and IR light is especially useful during blooming stages as it speeds up flowering time and boosts yields. Turn your seeds into your own supply!
  • WELL MADE & SOLID CONSTRUCTION: The SF4000 produces no fan noise, comes equipped with a branded high safety performance driver and good quality waterproofing. The updated aluminum material is thick and sturdy and doesn’t put out a tremendous amount of heat while also providing high-quality protective covers for cables and arriving in user-friendly packaging. The quality components mean the light lasts longer and saves you money.
  • As a professional manufacturer of Led grow lights for more than 10 years. Spider Farmer has always insisted on creating more efficient, suitable and high-quality home planting equipment for plant growth, and strives to become a trusted partner for every grower! You will get a Spider Farmer SF4000 grow light, instruction manual, a pair of silver hooks, a pair of black hangers.
