SZHLUX 620W High Output LED Grow Light for Indoor Plants

【High Efficiency and Low Energy Consumption】 SZHLUX LED Grow Light employs the latest high-yielding diodes technology, ensuring both power and efficiency with an impressive 2.9 Umol/J energy efficiency rating. It delivers a powerful light output with a uniform canopy penetration, resulting in maximum yield increases. With a 620W actual power and 1944 LEDs, the effective footprint covers 4 x 6 ft.

【2023 Upgraded Dimmer Modes】 This LED grow light features four dimmer modes tailored to different plant growth stages. Turn it to 40% on the first dimmer for a mix of white light bars to start. At 100%, all white LEDs will be on, ideal for seedling and growing. For the second dimmer, set to 40% to activate warm white, red, and IR LEDs, and go to 100% for blooming and fruiting. This ensures plants receive full-spectrum nutrition at every stage.

【Timing and Daisy Chain Support】 The newest version includes a timer switch, allowing you to adjust the light schedule based on your plants' growth stage. Moreover, up to 100 lights can be connected using network cables, ideal for large or commercial grow operations. Compared to HPS lights, our LED grow light cuts costs in half while significantly increasing yields.

【Sunlight Full Spectrum】 Our plant lighting closely mimics sunlight, with over 95% light energy being absorbed by plants. Available in 3000K, 5000K, 660nm, and 730nm IR, each light bar provides the necessary spectrum. 3000K lights offer more reddish light, promoting flowering and fruiting, while 5000K provides more blueish light, supporting robust seedling growth. 660nm and 730nm IR light enhances photosynthesis, increasing both yield and crop quality. Each light bar can be replaced with a UV light to suit your needs.

【Trapezoid Tube and Fanless Design】 Our LED grow light features an original trapezoid-shaped tube for a larger illuminated area than T5 and T8 tubes. A premium aluminum shell and fanless design ensure faster heat dissipation, making your growing environment more comfortable and quiet. This design allows plants to receive more energy and prevents overheating.
