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 150 x 150cm,  Flowering footprint is 120 x 120cm.

• NEW DIODES ARRANGEMENT & DIMMING DESIGN: Upgraded SF4000 growing lights. The diode arrangement gathered at the edge makes the PPFD more uniform, and the dimming knob be adjusted the light intensity at liberty. Multi-light Connection with unified dimming is especially beneficial for large areas of indoor plant growing and commercial planting.
• 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.
