Light works great. Hooked up with chain on metal shelf to grow seedlings.

Cool lights. I like how they can all run off of one setting when linked. They do not daisy chain the power supply so make sure you have enough open sockets for them. I paired them with the vivosun digital timers, works great.

Ballast arrived in a timely manner. It was a direct replacement for my bad ballast.

I picked this up for my wife and she loves it. She is a little addicted to houseplants lol. These are a beautiful addition to her collection and the lights are a really nice touch, my only complaint is that it still has to use a cord to power it up. But I couldn't bring myself to remove a star for that, that would be petty.

I am at the end of the second week of flowering and am very happy with these lights. It is important to note that the light is ideal for a 2'x4' area max. The PAR lighting map the manufacturer shows is not from this light. Even considering this, the value of this light at $138 is fantastic. I am running two lights in each 4' x 4' growing area and am very happy. Having 600+ watts for under $280 is a fantastic deal. With two lights per 4' x 4' space, I can easily have over 1,000 ppfd when needed in the greenhouse.
Update: i added 4 photos from 3-4 weeks before harvest. For a greenhouse, these lights are ideal.
Update: The video is 4-5 days into flushing. I am very happy with the lights performance. I will continue to use these lights without hesitation. I am very happy.
