The ViparSpectra L1000 is a mid-tier, full-spectrum LED grow light optimized for a 4’x4’ grow space. Powered by high-efficiency Samsung LM281B+ diodes, it delivers a potent 2.9 µmol/J at just ~150 W power draw - comparable to much larger HPS/MH systems, yet significantly more energy-efficient. Designed for silence and long-term performance, the L1000 uses large passive aluminum heatsinks, eliminating the need for fans and allowing for noise-free operation and excellent thermal stability. This grow light offers a balanced full spectrum, including key wavebands - warm 3000 K, cool 5000 K, deep red 660 nm, and beneficial IR 730 nm - supporting healthy plant development from vegetative growth through flowering. With a user-adjustable dimmer knob, growers can fine-tune light intensity to match each growth stage. The ViparSpectra L1000 is perfect for growing 6-9 plants. Need more coverage? Consider the XS4000, for 9-12 plants. Need less coverage? Consider the KS2500, suited for up to 3-6 plants.
