bars way to close to each other. Spacing 3-4 inches apart would provide better covarage, the do push a lot of umols but only in the center. Adjustable panels is nice. Power factor is a bit meh, but better than my spider farmer that i bought before I came across this brand. I tried a lot of cheap chinese leds and these guys came out on top so far.

I love these lights. They are lightweight, easy to install and use. My plants have gotten so "happy" and so lush and vibrant. I am also sowing tomatoes from seeds indoors, and it's helped their growth.

I can't say one bad thing about this. I use it to focus more light on my carnivorous plants, but everything around it benefits as well. Sturdy but not overly heavy. Won't fall over on its own. Easy to position. Barely puts off heat, don't touch the bulb obviously.

Since cannabis home grows have become legal, I have considered doing my first ever grow and Vivosun has made it possible. I was gifted a 4x4 foot tent by a friend who didn't measure his basement height before buying it. Upon completion of my research into the subject, I found the vivosun brand to be the best option for quality and value. I ordered one light as you can see in the photo and quickly realized that I would need a second. This worked out well as I had two tall and two shorter plants that responded well to the varied height lights. I am about 11 weeks into my grow, have just shifted to 12hr light and my plants look fantastic! Both boxes included all the hardware, as some people have indicated can be an issue. The tent my friend gifted me was missing the reflective flaps. I have made my own to replace the missing parts of the tent. I recommend this light for smaller 2x2 and 2x4 tents, but double up if you have a larger 4x4 tent. These lights are amazing!

Good quality
