Customer Reviews for VEVOR 300W LED Grow Light, High Yield Samsung 281B Diodes Growing Lamp for Indoor Plants Seedling Veg and Bloom Greenhouse Growing, Full Spectrum Dimmable, Daisy Chain Driver for 3x3/4x4 ft Grow Tent

Works perfectly for my vegetables

I added these to the lower half of a tall but smaller shelved greenhouse that light wasn’t making it to the lower shelves on. It’s worked perfectly and stayed cool enough to close the doors completely.

This is one bright light! It’s got blue and red light components as well as full spectrum white and well suited for any grows throughout the plant process. The entire back of the light is sold metal and acts like a huge heat sink.even the power supply is raised off of the back to allow heat to dissipate from the power pack. This is a large unit - for me it takes up much of my grow tent area. Just for reference, I tested this light with an electric watt meter. At 25% it starts out just under 100 watts. At each step up, it adds another almost 100 watts until full power, it’s at 391 watts so essentially it is at what they advertise at. Compared to the 400w HPS lighting, this is light years brighter (pun intended!)

Vevor took a page out of Samsung/HLG book. the 400w is a lot like the old HLG550. I'd even say they did a better job in some areas, like the remote dimming plus built in dimmer. My lights are the V1 QB288 using the same diodes as this board. I customized mine into Scorpions, before there were Scorpions, and run the driver's remote to save on HVAC for my room. I had no qualms taking a saw to my HLG's but the Vevor is a little too polished to DIY, so I'll be using this in it's own tent. It should be perfect for a 3' x 3'

Vevor makes some impressive indoor growing products and their grow lights are especially nice. I've used their tents too and been pleased with them. The results I've had with them are so much better compared to some less-known brands I've used. I have two grow tents, a smaller one for starting plants and then a larger one for plants that are already growing, so I've found the Vevor lights put out the amount of light needed to get healthy plants. This light is large enough for a small-medium size tent. If you have a larger tent you'll want to get a few so you get full coverage inside. This particular light doesn't put out much heat, so I use my fans more for moving air through than needing to cool the inside temperatures down. This is a nice change since some lights put out a ton of heat! Overall I'm very pleased with the Vevor lights and the results. Their build quality is nicer than a lot of the lights on the market and I get consistent results using them.

I love this light. It's putting out enough lumens to do the job. I have grown with 400w high pressure sodium and metal halides in conjunction, 2 of each for 1600W of light. Those lights use a LOT of energy. This one doesn't use anywhere near what those used to. It seems bright enough, and it's a super simple unit. Just a metal plate with tons of led's on it and a ballast attached to the back. It comes with two metal hangers, and that's all you need to get started. So far I'm very pleased with this light. We're using it to start our garden indoors to get our seedlings going. It easily covers a 5x5 area with enough light for this, or full on veg or flower cycles. This is very nicely made light with high quality components, and I would definitely recommend it.

This light offers full coverage. Works great and is easy to set up have some weight to it so to hang it make sure it's from something sturdy. Every single light works great value for the money made out of amazing quality material. Low noise when in use. Super super easy and simple to use.

This grow light is GIGANTIC. Was really not expecting it to be as big as it is. It covers a very large area, perfect for a large scale garden germination setup. Comes with included hardware for mounting/adjusting the height of the light. Has 3 different lighting modes - 25%/50%/100%. There is no timer which is the only downside so you have to manually turn this light on and off. VERY bright, even on 25% lighting. As expected, this has done a really good job at accelerating the plants growth even now in the winter. Very strongly reccomended.

Well it's day 1, just hooked it up and everything is great so far. I have it hooked up to my AC Infinity controller 69pro using RJ cable as this light has 0-10 dimming and it works flawlessly. Very bright light in my 4x4 pics shown on brightness of 4/10 and fills the tent pretty well. Barely notice heat on this level. My plants can see the difference already in response from the last light. I will update later with more progress info and how it holds up over time. Update! Light is still working great and the plants absolutely love it and have responded very well! Very nice light.
