DC4000 Grow Light for Indoor Plants, Dimmable Full Spectrum LED Plant Light | BESTVA 400W LED Plant Light with Veg/Bloom Mode for Indoor Growing, Plant Lamps for Seed Starting Vegetables in 5x5 Grow Tent

I have three of these in a 8x10 area. They have worked extremely well for both vegetating plants and equally well for blooming. It has three quiet cooling fans per light. No air conditioning needed as lights generate little heat in comparison to high pressure sodium lights. BESTVA is a high quality light at the low end of price.

I've owned and currently operate a few Bestva LED lights for my indoor garden. Always work well and super good value for the money considering it's price point. Recently I had an issue with some of the led bulbs on my newer 4000 and contacted the customer support team. They immediately worked with me to go above and beyond and agreed to send me a replacement vs repairing my existing unit. Couldn't be more happier with Bestva as they stands behind their products.

I am very pleased with these lights. Not too heavy, easy to set up and most important my plants love it. I have 2 of these and also one VivoSun and have to say that Bestva lights seem to be better looking at how the plants respond to this light.

With over 80 plants in our indoor greenhouse this light gives them all maximum light

Had to send the first one back because it was missing parts and looked used otherwise I'd give them five stars really nice LED light, what a world of difference. Great upgrade

My seeds broke ground within three days of planting!!! I I’m very pleased with this product.

***My review below was originally 5 Star but since the company has repeatedly avoided my emails and not fulfilled their promise, I would suggest all possible purchasers take note. Not what I would expect. I spent days investigating lighting sources before deciding on this choice. The company is excellent to deal with and Amazon makes the decision even easier. I have waited to write my review until after many continuous months of usage. The performance has been superb, the electricity cost well within budget and no issues at all after 6 months. This was my second unit purchased after having purchased the 3000w unit a few months earlier. Presently I have the 3000w & 4000w units and am very satisfied and recommend this company and products to anyone in the market for top performance lighting.

Lighting is great for my auto plants. Started my garden inside this year and I am happy with the results. The summer ended before harvest this light is a life saver. My only complaint is the short cord.

Mon ami l'adore, elle puissante et fait une belle job

I’ve tried a bunch of different lights over the years and this one is still my favourite. Don’t waste your money elsewhere. A++++

Working so good

I can't criticise much on the quality of it other than the massive price of $499. Its debatable whether it beats out a 1000W HPS let alone 4000W of HPS. Is it worth it? Yes and no. It has its pros and cons. Not really a fire hazard like an unsupervised hid could be , which is why i got it in my new tiny apartment as well as the slightly lesser heat. But HID puts out much , MUCH better spread coverage still. The one thing about LED that i personally think is their Achilles heel is the largely directional light it gives off that causes a huge hotspot directly underneath it but loses brightness (PPF) quickly when you stray away from directly under it, (UNEVEN COVERAGE). Don't be fooled neither , these guy's are 606W actual draw and put out big heat (just not directly onto the plants) . So you will need some way of moderate ventilation like an open window and basic fan at the very least. In my bedroom it heats it up pretty good, just not quite as bad as HPS does , but only a slight improvement on heat ( maybe 20% less than a 600W HPS). But if you're tenting, you will definetely need a decent ventilation setup of some sort. I'd still say HPS is KING and results are better but these aren't horrible neither, just very costly. I'll get HPS running again in winter and save these for summer i think. Happy growing!

After testing for a month this led did it's job, plant love it. Recommended!
