Customer Reviews for VEVOR 400W 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 4x4/5x5 ft Grow Tent

I am a college professor specialized in environmental crop physiology. We purchased commercial-grade growth light from other companies before, which cost way over $1k per piece and a lot of them had quality issues and eventually the brightness fade off over time. Gave this light a try and used a scientific-grade PAR (photosynthetic active radiation) sensor and realized that this unit can put out about 1200 to 1300 µmol m-2 s-1 on full power, which is more powerful than our $1k light, which only gives 700 µmol m-2 s-1. Just to put in perspective, 1200-1500 is almost full-sun condition outdoor. I need to find out how long they can last, but as of now, cannot be more happier.

So far so good! Very impressed with this light and it is providing all my little plants what they need! As an old retailer I can tell you I am very competitive on all my purchases and this item is highly recommended.

This light is amazing. My plants love it. I’m getting way bigger plants now and it’s compatible with other hubs as well. And you just can’t beat the price.

Quality and price of the light is amazing! Unfortunately vectors customer service is terrible. My light arrived damaged and not working. They offered me $50 after spending over $300! They take forever to respond and when they do it’s in the middle of the night. They ended up refunding me 2 weeks later but it was a hassle!

Awesome deal on a great light. Have it in a 4x4 tent. Got a second for my 3x3. ,.........................,....,......,...........,.........,.........,.

A fine light and a nice price. Perfect for starting veggies and flowers in a 3 x 4 x 6 grow tent laid on its side.

Haven't use it yet,but I know that it's a good product that why I purchased it,it's still in the box,but it will be use soon

First off. I love that the ballast is raised off the light. You could technically move it to the outside of the tent if you’re handy with wiring but I wouldn’t recommend it. It has solid hanging mounts that I don’t worry about and it’s very bright. I don’t doubt the wattage. It doesn’t get overly hot either. Solid light at a solid price. It doesn’t feel cheaply made at all and the panel is nice and thick.

This is the fourth light I have purchased. I absolutely love them. I'm able to get the par I need while only having to use 50% of the lights power. The price is amazing as well. I was able to get 4 lights for the cost of one from other brands. Thanks again Vevor.

There are a lot of grow lights out there. Many of them cost far more. I don't know that any could do any better than this one though. Having purchased this one light as a trial, I now have several Vevor lights of different wattages and love them all. I am sold on Vevor and see no need to ever look elsewhere.
