New in Box Text only Please Stunning features with high-quality components Producing a total PPF output of 1620 µmol/s and a Photon Efficacy (fixture efficiency) of 2.7 µmol/J, X 600W Pro LED creates a homogeneous light spread at a close distance from the crop canopy, resulting in outstanding results when used in indoor multi-layer cultivation systems, grow rooms and tents. When compared to regular similar wattage High-Pressure Sodium solutions the P-TEK X 600W PRO LED can achieve 30-40% less HVAC capacity and increased yields of up to 30-60%. The X 600W PRO LED is built using high-quality and durable PHOTONTEK drivers and top bin LEDs generating an optimized full-spectrum light source ideal for veg and flowering stages. The X 600W Pro is designed with both vegetative and flowering growth periods in mind and the LED may be dimmed, allowing you to adjust PPFD levels produced without losing efficiency.
