Viparspectra KS3000 300W LED Grow Light

where to buy grow light bulbs, The next generation Viparspectra KS3000 LED Grow Light is a unit that benefits both the grower and the plants.



  • EVEN PAR DISTRIBUTION– Beneficial and reliable choices for your plants. Other brands distribute too much light to the center and too little to the outer edges. The larger size of the KS3000 ensures every plant from the corner to the center has enough light.
  • EXCELLENT USABLE PPE- KS3000 enables indoor farms to reduce their energy use.
  • DETACHABLE POWER SUPPLY- Limit the temp in your tent as the distance between the plug and the light is 13.12ft (400cm).
  • FULL SPECTRUM- Consists of 3000K warm white, 5000K neutral white and 660nm deep red.
  • HIGH EFFICIENCY- Features the industry-leading photon efficacy of 3.10 μmol/J SAMSUNG LM301H and OSRAM 660nm diodes.
  • DIMMABLE- Flexible dimmer allows you to adjust light intensity from 0% to 100%.
  • WORRY FREE WARRANTY- 36-Month US Local warranty and 30-day money-back guarantee.

Recommended for:

  • Commercial grows
  • Greenhouses
  • Home grows (rooms and tents)
  • Soil, hydroponic, aeroponic, or aquaponic systems
  • Indoor farming or gardening






Usage Suggestions

  • Seedlings – You will need to hang the light high due to the delicate nature of seedlings. We recommend a break-in period of about a week while a seed has broken the surface. The first set of real leaves should be present while the seedling has been above ground for about a week.
  • Clones – Clones are a little bit hardier than fresh seedlings, but still, need to be given gentle light as they are entirely rootless when first cut, and need to conserve energy and moisture to transition into a rooting stage.
  • Vegetative – The deeper red spectrum is utilized less by the plant than when it is in flower. It uses high levels of white light that are essential for creating lush, thick plants that have tight internodal spacing and minimal stretching.
  • Flowering – The plant has much work to do and is performing many complex biological processes in producing flowers and fruits. Because of this, the plant now requires large amounts of light.
  • Late Flower – Most rapid development has stopped, and the plant is gearing up for the scene in which the large flowers and fruits will mature or ripen.

If you expose plants to high light intensities too early in the crop cycle, you can damage chlorophyll pigments causing photo-oxidation (photo-bleaching), so we recommend slowly increasing your light intensity as your plant develops.
