What makes this a great grow light?

Commercial grade, IP65 rated against water and dust intrusion and built to last. Plug it in, turn it on, and the extreme light intensity is heavy on the eyes even after adjusting. This is a high performing grow light that takes advantage of the higher quality LED chip and manufacturing capabilities from Taiwan. Even though the spectrum goes well into the reds to benefit flowering plants, it still produces a high CRI similar to 4500K color temperature to help your vision when working in the grow. It's tough to accurately check your crops for disease or nutrient deficiencies when everything is blue/purple/red. This light does these things extremely well:

  1. Provides great light intensity for wide canopy coverage and penetration
    The intensity of the LED's delivers a high amount of PAR to the plants at canopy level and the light is able to penetrate further underneath the canopy to encourage more bud sites and flower development
  2. Covers wide canopy area evenly 
    Each of the 4 light bars can individually adjust up to 30 degrees allowing you to increase canopy coverage area or. focusing on a particular grow area. Linear bar design minimizes footprint if using in mixed-greenhouse conditions.
  3. Flowers extremely well
    Our light combines the best spectrum for flowering/bud development with the intensity and power necessary to produce . We recommend CO2 supplementation with the amount of PAR this light can deliver
  4. Low heat output, save on AC / HVAC costs!
    The amount of heat this total unit outputs is 1/3 of HID / HPS. This also allows the capability to place the grow light closer to the canopy level without burning the leaves allowing for higher PAR delivery at canopy levels and below
  5. Solid Construction
    It's seriously heavy-duty and built to last. We back this up with a 3 year warranty as well. Let us know if you have any questions about using this light in your grow requirements!
