VIVOSUN LumaLight 100W LED Grow Light, Full Spectrum Plant Light, Smart Dimmable & High PPFD for Indoor Plants Seedling Vegetables Bloom, Fits 2×2/2×4 Grow Tents, 2-Pack

High quality

I bought these solely based on a YouTube comparison video that found these were the best bang for your buck when tested against similar products by multiple popular brands of LED grow lights - using the same crops, and in the same conditions (sorry, I forgot the user's YouTube handle). I haven't regretted it and was so happy I recently got two more. I like that I can dial up or down the output, though I have mixed feelings about it being selectable only in 25% increments - especially since I use it quite a bit closer than is recommended (maybe 6-7 inches or so), to conserve space. But I've found most of my plants only get stressed at the rather intense 100% setting. They do produce some heat so keep that in mind if you use warming mats for germination (I do not).

Excellent!! Get the 2 pack

Work as they should.No issues so far.

I do not have any tools to analyze if the lights are helping with the plants growth. However, our observation for the past two weeks, all our seedlings are growing indoor normally and they are leaning toward the lights as expected. This unit uses LM301 LED diodes which are great-bright. VIVOSUN VS1000 has brightness control stepper switch to adjust the brightness to factory preset levels. It was very easy to mount in our rack with the accessories provided. We are happy with this product, and we are pleased to write this review.

My spring crops all start with these lights. Love em. Easy to set up and store as long as you keep the box they come in.

Couple things about the units I wished I'd known before hand. I bought the twin pack. The first unit comes corded but unit # 2 does not. It comes with an aux wire to connect the first unit to the second. So if unit #1 for some reason quits working thru the power supply, the second unit will also stop working and therefore useless. Second, the hangers are perfect for the balance of the unit itself, until you add in the weight of the power supply cord then it throws the balance off the unit causing it to tilt. The only way to fix this is to lift the power supply cord up and my grow station does not have anywhere for this to be done. I'll have to figure something out to fix this issue, but it would be so much easier if the unit had a removeable hanger system on it so the purchaser could decide on how they wanted to hang this unit. Other than these things, it was very well packaged, seems to be built with quality and the lights themselves are very powerful and looking forward to getting this setup fixed to where I can start my seeds this year for my garden. I only gave a 3 Star rating because Grow Lights shouldn't be this hard to set up.

We attached two of these well made lights to a pipe hung between two large padded bike hooks and set our plants below them. The quality of the light is excellent and all of our plants are thriving. We have a fern which I set on the other side of the room and it is doing better than when we have it outdoors on the front porch. The ability to set the first light to control the second and daisy chain them is perfect. We can run a single timer and both lights work perfectly.

Reading some comment that the light was not powerful enough, I was a bit afraid, but gosh, this is so powerful that I am only using it 75%. I think what people are complaining is that it's not covering that much. I had to buy the 2 lamps package because one was not enough to cover my whole 4X2 tent. I do not grow cannabis, I grow sarracenia pitcher plants, and they usually require full sun all day long, so I hope that they will be super happy with this light. It's also 3 years warranty, so all I can say is wow. Very happy with the color of the light as well. Be aware that the one lamp deal does NOT include the protection glasses, but the 2 lamps package does.

VIVOSUN VS1000 LED Grow Lamp: The first crop was indoors due to the cold and these lights did their job. Very easy to assemble, I ended up purchasing 2-additional lights for more coverage. Connecting all 4-lights to each other and the controller was much easier than I had expected. (I'm not a fan of electrical anything) These lights have already paid for themselves, so I highly recommend purchasing these for your growing needs.

Excellent produit, je recommande, mais date de livraison non respectée, mais pas à cause de Vivosun

Wahnsinn, es macht einen riesigen Unterschied, welche Lampen man für Anzucht von Pflanzen nutzt. Definitiv zu empfehlen.

Looks and feels like a premium light... a little expensive for the watts though. Included hanging hardware is nice, as is the dimmer feature. Makes some heat a 100%. No regrets.
