The ViparSpectrum VS1000 LED Grow Lights are built with high-efficiency Samsung LM301B LEDs and trusted MeanWell driver, it delivers a full spectrum combining 3000K warm-white, 000 K white, 660 nm deep-red and 730 nm IR. This rich spectrum ensures coverage from seedlings through bloom for robust growth and higher yields. Boasting ~2.7 µmol/J efficacy, this fixture achieves strong photosynthetic output per watt. It replaces traditional 250–300 W HPS/MH lighting while consuming just 100 W—perfect for economical indoor gardening. A built-in dimmer knob enables fine control of light intensity across growth stages. The fanless, solid aluminum heatsink design runs silently and dissipates heat efficiently. The LEDs are evenly coated and potted for moisture resistance, extending lifespan and enabling safe use in humid grow environments. The ViparSpectra VS1000 is perfect for growing 1-2 plants. Need more coverage? Consider the VT1350, for 9-12 plants, or the VT600, suited for up to 3-6 plants.
