The Future of Indoor Gardening Has Arrived...Grow KIND!
The K3 - L450 LED Grow Light: Replaces 450w Traditional Grow Light!

After years of rigorous research & development, the KIND LED Grow Light is complete, and it is a work of art. The K3 series LED grow lights are comprised of high powered 3 Watt Light Emitting Diodes featuring a proprietary intensified spectrum designed for flowering large yields. This revolutionary series of LED grow lights will produce the biggest and best yields, while consuming approximately half the electricity and producing virtually no heat. Your KIND LED will cultivate record breaking yields, both in quantity and quality, while running cool, quite and efficient. Guaranteed!

  • KINDest Yields:
    700 mA driving current increases diode efficiency & output resulting in a brighter, higher yielding footprint.
  • KINDest Spectrum:
    Proprietary 12 bandwidth spectrum. Complete 3 Watt "Perfect Spectrum" meaning, the wavelengths emitted by KIND are the exact, appropriately proportioned wavelengths that plants utilize during the growth cycle.
  • KINDest Intensity:
    Secondary Optical Lens enhances diode efficiency and magnifies PAR to facilitate easy rooting and maximize yields. The Secondary Optical Lens is basically a magnifying enclosure that encases the diode which focuses the diode light emission creating a greater intensity & greater canopy penetration leading to larger fruit & flower production both at the top & bottom of plants.
  • KINDest Quality:
    Extra large heat sinks, quiet fans, precision drivers and superior craftsmanship.

KIND LED vs. HPS: These KIND LED grow lights use only about half the electricity as HPS lights, and produce much more yield per watt. Studies have even show an increase in oil production & quality, closer inter-nodal spacing, and denser fruits & flowers. Also, because KIND LEDs produce less heat, they do not need to be air-cooled like HPS lights, therefore eliminating the need for additional fans which reduces noise and costs.

What Is A Heat Sink? Heat sinks are used in optoelectronics such as lasers and light emitting diodes (LEDs), where the heat dissipation ability of the basic device is insufficient to moderate its temperature. A heat sink is designed to maximize the surface area in contact with the cooling medium surrounding it, such as the air. Because KIND heat sinks are extra large, the LED runs nice and cool.

Diode Efficiency: An important consideration in choosing an LED grow light is the power of the diode chip set, or wattage. While no diode runs at maximum output, the KIND 3 Watt Diodes run at approximately an 80% efficiency with no detrimental degrading of the chip, incorporating the perfect blend of intensity, durability and low operating temperature that all LED lights need to succeed. The KIND consists of 8 modules with 15 diodes each for a total of 120 at 3W per equaling a true wattage of 360. Given the 70%-80% efficiency, the fixture runs at a ~288W output.

KIND to you. KIND to your plants. KIND to the environment. Grow KIND.

Customer Reviews

Surprise surprise surprise Review by Closet grower
Used the Kind K3 450 to replace a 400 watt hps light in a 2x2 locker. The benefits of the k3 were immediate in assisting in temperature control overall and increased grow space with eliminating the heat from a bulb. Quiet, efficient and most of all it out produced my traditional light at a third of the electric cost. I bought a second light for my other locker I was that pleased with the results. Dense, phat, colorful buds definitely a crowd pleaser
