Kind LED K3 Series 2 – XL600 LED Indoor Grow Light

LED Grow Light Bulbs

Taking cues from it’s best-in-class big brother, the NEW K3 XL Series offers the same unprecedented results as the K5 Series with secondary optical lenses and a new expanded perfect 12-band spectrum in an easy to use, plug n’ play, seed to harvest fixture.

See how the NEW K3 XL Series grow lights stack up against the competition. Designed by growers, for growers, KIND LED Grow Lights are specifically engineered to match the needs of the plant and outperform any other grow light on the market.

  • Amplified quality and potency, with newly enhanced UV diodes to increase terpene and flavor profiles.
  • Significantly increase flower density and harvest weight with re-calibrated secondary optical lenses that focus light intensity and deliver 200% greater canopy penetration.
  • Optimized diode distribution reduces the hots spots commonly found in LED grow lights, resulting in balanced, rapid growth across the entire footprint.
  • Lifetime professional grow support so you never have to grow alone.

Kind Grows “Kind” Grows

Kind Komparisons:

The Kind K3 LED grow lights are the only 3 Watt grow lights that:

  1. Use a proprietary 12 bandwidth spectrum that runs at 700mA.  Lesser LED grow lights run at 500mA with only a 6 bandwidth spectrum.
  2. Thick, heavy duty 2 CM aluminum circuit boards that dissipate heat much more effectively than other LED lights, making Kind LED lights run more effectively and smoother throughout many, many harvests.
  3. Revolutionary “Secondary Optical Lens” for maximum photosynthetic penetration from plant canopy all the way down to the stem.
  4. These Kind LED lights will match or outperform any other 3 watt LED grow light, including the very expensive HydroGrow LED lights, GUARANTEED!


These Kind LED grow lights use only about half the electricity as HPS lights, and produce much more yield per watt.  Many studies have even show an increase in oil production and quality, closer inter-nodal spacing, and denser fruits and flowers.

Also, because these Kind LED grow lights produce less heat, they do not need to be air-cooled like HPS lights, therefore eliminating the need for additional fans, which also makes them run quieter.

Kind LED vs. other similar LED companies

These 3 Watt Kind LED lights will match or outperform any other similar 3 watt setup that is seen often throughout the web, regardless of price or claims, GUARANTEED!

You may notice that a few different 3 Watt LED lights (DO NOT EVEN CONSIDER SINGLE WATT LED LIGHTS) that look very similar to these, and as far as diode wattage is concerned, they are.  What differentiates Kind LED lights is that they have more bandwidths (12), which equals a much fuller and more complete spectrum (crucial when it comes to photosynthesis).

Another major Kind advantage is the use of the revolutionary “secondary optical lens” which penetrates deep into the plant canopy to facilitate easy rooting and maximize yields.  Kind LED grow lights are the ONLY 3 Watt grow lights that feature a 12 bandwidth full spectrum LED panel, a secondary high intensity optical lens, and 2CM aluminum circuit boards.

Kind to you. Kind to your plants. Kind to the environment.

Grow Kind.
