Running three units in my basement grow tent. Set mode at 80% brightness 14hrs/day through the app. Finally ditched my bulky old system.

This is a light for plants, but it’s not a grow light.

If you’re okay with that (I am) then know that it works decently for small, medium, and smaller large plants, but not tall enough for indoor trees.

SPECIAL NOTE: As an approved ecogrowhawaii.com Vine member with Gold status, I am trusted to select items for review (sometimes from a list of almost 130,000 options). Many of these items are new to the market, or a seller simply wants some additional exposure for their product. I am NOT required to review every item in exchange for receiving and trying it out. I only order products that are important to me (ones I know I have an interest in and will use), and always strive to provide an honest evaluation of my experience. I do not automatically give a 4- or 5-star review, because the community of ecogrowhawaii.com purchasers deserve to know real thoughts and experiences. So, my reviews are always and only based on my use and testing of the product. In that you can trust 100%. It's also important to note that I pay almost 30% in federal income taxes for each item that I receive, whether I review it or not.

I bought these for my greenhouse. They were super easy to use and seem to work. Great they are very bright.

noticed our plants were much healthierlooking after a week of use

The way these work as a string of lights is really convenient for my grow room, but I'm not sure if the shape of the lights is better than having a panel, but I also see that with this shape, I can change out a bulb that no longer functions properly, so I've going back and forth, but ultimately, the light itself seems really good, I haven't actually had to change any of the bulbs, even running the lights 12 hours a day. I don't feel like they put out an excessive amount of heat either so I could probably use them in my indoor greenhouse for my high humidity plants if I really wanted to, I think.

The advertised ppfd chart shows a better read out than what the product actually offers. Claims are grossly actualppfd is hundreds lower. . Also the exact same model at same time is $100 cheaper on the vivosun website than at the vivosun ecogrowhawaii.com store. Research this company on Google and reddit and look at many of the 1 star ratings on ecogrowhawaii.com. There are over 5000 ratings. They try to justify the power output by environmental impact. Seriously.... bad company.
