VIPARSPECTRA P1000 LED Grow Light for Seed Starting Vegetables Bloom, Dimmable Plant Lights Dimming Daisy Chain Grow Lights for Indoor Plants Full Spectrum for 3x3/2x2 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.

These grow lights are very high-end high quality you can tell when you pull it out of the package they're extremely bright I highly recommend you use a meter app on your phone to set them at the right brightness or you'll burn your plants they're that bright but they work very well consistently reliably and they make your plants grow thick and healthy as opposed to thin and lanky if you have it set right there's no reason your plant should get leggy at all I feel that they are worth the price for these units and they've only improved them on each new model I have four of these and use them strictly for seed starting on a rolling rack system so I love that you can adjust the brightness there's a dial on the side of it to adjust the level of brightness because I can't raise and lower the picture itself so this allows me to reduce the intensity on the young plant so they don't get burned and as the plant grows up closer you can turn it down it comes with a jack that you can link them together to operate on a controller to each one and daisy chain them together

This is a high-quality industrial-grade piece of equipment. I purchased it for starting veggies from seed in my house. It’s slim and encased in a metal housing with cooling fins. The LED surface is protected by a lamination. It comes with ratcheting mounting hooks and ropes. 100% power is much more than I need for seedlings so I am able to run this at 50% at 16 inches high, which will only consume about 35 W. Previously, I tried out one of these consumer level lights sold at a home improvement store, which was made of flimsy, plastic and terrible snapping plastic connections. This unit has an industrial hardwired power cord. Great value.

Upgraded to this light for starting my pepper plants, and so far, all is good. Setting it up was quick and easy, and I'm very pleased with the suspension system. Adjusting the height is so much easier than my old metal-hydride setup. The power cord is a little on the short side, but I was able to adapt my power system. The light does generate some heat, but not nearly as much as my old setup. The dimmer works perfectly and does turn the light off when set to zero. The intensity of the light is amazing! Even when I had it set to 40%, I had to increase the height of the lamp to protect the plants. The 4 X 2 coverage is good, but I do rotate the plants, so everyone gets equal shares. The light is not being used in a grow tent. I do wish that there was a built-in timer though, but that isn't a deal breaker. I just use my old timer. Some have expressed concerns about some of the red LEDs not working or are dim. Those malfunctioning, or dim LEDs are IR emitters. Our eyes are unable to see IR. We sense it as heat. Overall, I'm very pleased with this grow light! I do wish that it was a little bit lighter weight wise, but I only use a grow light for about 2 months out of the year so suck it up buttercup, lol! It will be interesting to see if everything is the same after all of the plants have been transplanted, the light has been put into storage and set up for next year's season. Will it perform the same? I will update if there are any changes, but at this point I'm very pleased and the plants are loving it! Highly Recommended!

Not strong alone with other light it's perfect

The VIPARSPECTRA P1000 LED grow light is a strong option for indoor plant growing, especially for seed starting, vegetables, and small to medium grow setups. It provides full-spectrum lighting that supports plants through both vegetative and flowering stages, making it versatile for different growth phases. The dimmable feature is very useful, allowing you to adjust the light intensity depending on plant needs and growth stage. This helps prevent overexposure for seedlings while still providing enough power for more mature plants. The daisy chain capability is also a nice addition if you plan to expand your setup with multiple lights. The build quality feels solid, and the light runs relatively efficiently while staying reasonably cool compared to traditional lighting options. It’s well-suited for grow tents around 2x2 or 3x3, providing even light coverage across the space. Installation is straightforward with the included hanging hardware, and setup doesn’t require much effort. Once in place, it delivers consistent and reliable performance. Overall, this is a well-designed and effective grow light for indoor gardening enthusiasts who want adjustable lighting, good coverage, and dependable results.

These are fantastic lights, especially for the price value. I will update if anything goes wrong, but the build quality is professional to my eyes, the lights are plenty bright for the space advertised, and although I haven't been able to fully measure their impact, I'm very confident they are doing the job. If I had to come up with complaints, it would be that the cord is only 6' long, and there's no daisy chaining. That's it... who cares? If this seems like it fits your space, get it.

easy to use an set up in a grow tent if you have a vivsosun tent like i do you will have to loop the hook around the bar to hang since bar is to wide to clip on. also like the diming option an also the light works good for keeping the grow tent warm with heating pad so i used it to get my pepper seeds to come up since were i live it is cool an need to start peppers ealy . so far working good

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!
