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

The VIPARSPECTRA P1000 LED Grow Light has completely exceeded my expectations! From setup to performance, this light is a game-changer for anyone serious about growing. First, the power and performance are spot on—true to the chart with no exaggerations. The light intensity is impressive, and my plants responded with vigorous growth and, most importantly, incredibly dense nugs. It's easily one of the best lights in its price range, hands down! Setup was a breeze, and the daisy-chaining feature is a fantastic bonus. It seamlessly connects to my Vivosun controller and even daisy-chains with my Vivosun light. The compatibility across brands makes this a versatile addition to any grow tent. I also appreciate the dimmable feature, which allows for precise control throughout the growth stages. Whether you’re starting seeds, vegging, or blooming, this light gets the job done with perfection. The driver is awesome, it does not get hot. I can touch it no problem. If you’re on the fence, don’t hesitate. This is not just a grow light—it’s an investment in higher yields and better quality. Highly recommend it! Tips: when hanging lights put them on the ground in the tent first then extend the pulleys to the light on the ground. After hooking both sides up slowly ascend the light. Much easier this way. If you really wanted to you could fit the P4000 in a 4x2 and have 5-6 inches on each side. But this light works.

Don't believe what people say negative about this light online. My garden loves it you have to place it a lit bit higher than the book says but they exploded with growth over a few days after I replaced an old light with this one. The one it replaced was three times as expensive than this one. Sometimes you pay for just a name not with viparspectra, with viparspectra you pay for results period 💯 thanks to viparspectra for making a quality light affordable. As soon as you open it you can tell the quality of the leds are a better quality than other brands an the housing is not cheap flimsy metal it's very thick durable metal. I like the heat sinks an how there is space between the housing an the meanwell driver so it runs cooler. I really like the adjustable dimmer. also the weight of the light Is so light compared to other more expensive lights. The performance of this light is so good you may need to turn it down a notch cause it's very intense. I recommend this light 💯

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..
