VIPARSPECTRA P2000 LED Grow Lights for Seed Starting Vegetables Bloom, 250 Watt Dimmable Plant Light Dimming Daisy Chain Grow Lights for Indoor Plants Full Spectrum in 4x2/3x3 Grow Tent

Unlike most other reviewers here, I didn't buy these to use in a tent. I wanted good quality led panels for use on a wire rack system for seed starting. I landed on these because they were the only-well reviewed panel I could find which came in the necessary dimensions. I purchased the largest size (11" x 39.4") because it would fit between the upright legs of my wire rack and extend slightly beyond the length of each 3 foot shelf. I purchsed 3. After seed starting I will use these for a planned indoor greenhouse cabinet build that will house my anthurium collection. The build quality of these is excellent and the mechanical output adjustment works well. I started some Jerusalem Artichoke and Apios tubers early this season. I had planned to store them until spring but it became obvious that they were not going to survive until then if I didn't get them planted (They were shriveling and many had become soft with areas of decay). They've been planted in nursery pots about 2 weeks now and the largest plants are already about 6 inches tall. They're going to be blooming by the time they can be planted outdoors at this rate! I've just started my first early seedlings (snapdragons) and will update how well they work for that purpose at a later time. They do get warm, but not so hot that they burn if touched. 3 panels in my 9' x 12' mudroom keep the space warm enough that I won't need heat mats. If you're looking for quality led panels, these appear to function well and are a good value for the price.

The most important things to understand .. with artificial lighting is the language .. this viparspectra p2000.. light is far beyond the capabilities it's limited to 2x4x5 grow tent is what it's claimed to light up correctly efficiently .. u can take it higher I will say this much if the lights pivoted it's would light up a 4x4x6 no problems it puts off plenty of light I see no reason to even run it a 50 percent at any stage I'm a 2x4x5.. period and it will flower and fruit just the same this is a awesome full spectrum light plenty of bang for the buck .. and it deisapates heat extremely well .. all u need is a 6 inch fan blowing down on the light while it's running and a intake fan and filter and exhaust .. but if ur on a budget them inline fans are a waste of money when all. U need is intake and exhaust . Ur good.. excellent light

I purchased a couple of the spider farmer lights with the Samsung LEDs after I had the mars hydro light for about a year or so. all of them the smaller 100W variants. Reading around and doing research, looking at product reviews endlessly- exhaustively trying to make the best choice. The mars light after 2 grows ( short grows with autos) 1/4th of the panel failed. Support was responsive but in the end wanted me to pay for a new light with a 20 percent off discount, this is well within their warranty period. The build quality seemed sub-par after getting the spider farmer lights. In the end, the mars light ran really hot ( I had no idea) and heated up a 6'x6' space to the point of needing excessive ventilation. The Spider farmer lights have a good quality feel and build quality and ran MUCH cooler, to the point It was about 90% less ventilation required. I went with them due to the name brand LED ( samsung) lights as everything pointed to them being much better. Overall after receiving THIS light, It kind of put it all into perspective for me. This 240W light outperforms (3) of the 100W lights from Spider farmer BY FAR. It also runs much cooler and is insanely bright, the plants love it! Overall, I am not going to pretend I know anything about the differences in the brands of LEDS and all of that. I do know that these " no name" LEDS on this unit are far superior in terms of cost and performance in comparison to the Samsung bulbs from my perspective. I get much deeper penetration growth, less stretching and much denser "fruit" in the exact same conditions. It's kind of shocking actually. The build quality of this unit is fantastic, the way it hangs and the lower heat it puts off, all of it down to the mean well driver they use. It does run hotter than the Spider Farmer lights, but the plants seem about "50%" more happy with this light. Maybe that is the difference, the efficacy of the light corresponds to the power wasted as heat, I am not sure. But for 240 watts at $130, compared to 300 watts of Spider farmer at $220, the spider farmer loses for sure. The only real thing I cannot attest to is the warranty/support of this brand or spider farmer, as well as the useful life of the products. time will tell, but overall I am glad I am not falling for the " hype" of "name brand" LED units. I see the results, I feel the results, I weigh the results on a scale. These units work fantastic, even better than the higher priced " name brands". Sorry mars and Spider Farmer but I think at this point all you have going for you is your name and all of the hype around the " Samsung" LED's. If I can pay half the price for twice the light and "fruit", I don't see why you couldn't either.

I’ve been using the VIPARSPECTRA P700 Grow Light for my indoor setup, and I’m beyond impressed with the results. The build quality is excellent—sturdy, well-designed, and easy to hang with the included adjustable ropes. The full-spectrum lighting is perfect for every stage of growth, from seedlings to flowering. My plants have responded incredibly well—healthier leaves, stronger stems, and noticeably faster growth. The brightness is powerful (11,000 lumens) yet adjustable with the dimmable feature, which is a huge plus because I can fine-tune the intensity depending on the stage of growth.

These lights work exactly like they're supposed to. I've never had any problem. They are the only lights I use for my grow tent. The only problem I had was the bundle came with a set of heavy duty hangers for an extra $8 that I don't need. The light comes with the hangers. I tried to send the hangers back but will only get a $2.21 refund. Mt old man said to just keep it. This sucks! Now I'll have one more unusable item laying around.

Upsides; Construction quality is phenomenal for the price. Exactly as advertised. Most people have mentioned, but the dimmer is incredibly smooth and precise. The light spectrum is pretty close to optimal, and includes both far red and IR diodes. Unsure if others who were complaining about the lack of IR knowledge what to look for, but it's there (just one IR diode on the P1000, unsure of the other models). It's also aesthetically a cool looking light, great colour scheme that matches up with most grow tents, if you are into colour coordination... Downsides; the driver seemed a little 'worn'. Scuff on the top leads me to believe perhaps it was refurbished? Seems cosmetic only, with zero affect on the light, so time will tell if the driver becomes an issue. The coating applied to the diodes for waterproofing seems a little sloppy/uneven on application, but I'm being picky (all diodes are covered, but much of the board is not). Lastly, they are a little over optimistic on the flowering coverage, as it's more of a 1.5ftx1.5ft coverage for flowering, making me wish I had opted for the P1500 instead. All in all, I highly recommend this light for anyone looking to grow one plant, opt for the P1500 if you want to flower a 2x2 full of plants.

Very happy with this purchase..

Muy buenas y por el precio excelentes, comprare más.

Los materiales son muy buenos, la luz es realmente brillante y en cuanto al espectro de luz es bastante adecuado, si lo quieres para plantas de interior que requieran luz, cactus o otras plantas en las que tengas que controlar bastante la luz que reciben realmente es un producto extraordinario, potente, duradero y bonito

Super!
