I did a ton of research throughout the board and also I could not find a light that supplied double switches for vedge/grow and that might be daisy chained to run one timer without investing a lot. Then I discoverd this LED grow light.

After doing some digging and also utilizing Kind LED lights prior, I made a decision to give the 600Watt a shot. I have had nothing but outstanding results and I’m a few weeks far from wrapping up initially grow with vehicle flower seeds using these. 

These lights are great, I have actually not had problem with maintaining temps, even during the summer; yet I have two carbon ventilation systems established in the room. I also make use of both veg as well as flower through the entire grow, as well as it creates amazing lead to both size and also effectiveness.


  • Seedlings/clones the light was best at 22-24 inches i left the light there and
  • I would then let them grow “into” the light to about a distance 18-20 inches and maintain that until flowering cycle.
  • During flowering cycle i used both Veg and Bloom switches and let the plants grow to a distance 14-16 inches.
  • Keep an eye on stretching during the first week or two of flower as you will need to adjust frequently, and these leds are strong so you don’t want to light burn your plants.
  • Heat is no issue but you do want good constant breeze on your canopy.
    I took a chance because there is not a lot of people who have experience with these lights with cannabis, but it well paid off.

This is a very solid grow light. I have been fascinated with growing and elements that effect the grow.

Of course, the soil/medium, nutrient (NPK), pot/container, environmental condition such as moisture, pH, etc. all come into play when you are growing a small and newly germinated sidling into a big flowering plant. Back to this grow light. When I receive the light the only instruction/manual that came with it was the hanging manual. No mention of wattage, lumen, PAR, spectral distribution, etc. The good news is that I was able to measure all of these but it took me a while to measure them as it takes a long time to accurately measure, record, and combine all the data into an understand big picture.

Generally though, the light penetration stemming from 1 watt LEDs may penetrate less than higher wattage LEDs.
