  • Energy efficient
  • Long lifespan
  • Low heat
  • Daisy-chain up to 7 pcs
  • 3 years warranty


  • Only one fan
  • No veg/bloom switches


Although it would have been nice to have veg/bloom switches like the bigger models in this series, some experimented growers using LEDs say these switches are useless and let them ON all the time and it works just fine.

Overall this LED grow light met all my expectations and my cannabis plants respond very well to his 12-band full spectrum.

I grow weed in an AeroGarden and organic soil as well with this LED. Of course, this LED produce bigger plants with higher yields.

I have also used this light to grow; tomatoes, bell peppers, culinary herbs, strawberries, and sprouted many vegetable seeds.

In my opinion, it would be difficult to find a better LED grow light in this price range.

The ViparSpectra 300W reflector-series is a solid pick and good value for your money. With a 3 years warranty and 30 days satisfaction money back, this is an easy buy.
