VIPARSPECTRA XS1500 Pro LED Grow Lights for Seed Starting Vegetables Bloom, New-gen Lens Dimming Daisy Chain Full Spectrum Grow Lights for Indoor Plants 2x2/3x3 Grow Tent Actual Power 150 Watt

First, let me start with the disclaimer that I live in NY and grow cannabis within the legal limits as well as abide by any other cannabis related laws in New York. Now for the fun part. I wish had taken before an after photos because my cannabis plant was 1/3 this size 2 weeks ago before I added two xs2500pro lights to my 4x4 A/C Infinity grow tent. She is approaching 3 feet now and over 18 inches wide. I’ve not done see any LST with her and I just started wind training her. My grow tent is located in a spare room equipped with a window a/c unit. My tent is ventilated by a 395cfm exhaust fan with an optional intake fan located on the bottom. I also have the tent equipped with an oscillating fan. I am currently running my lights at %50 and %40 (for the smaller plants. The light temp runs on average at 85F degrees at these settings. The drivers just outside the tent run at about the same temp. They can be easily touched with no harm from the heat whatsoever. These lights are incredibly bright even at %50. I have the drivers located outside the tent which I do recommend doing. I also purchased two inline switches so I am able to turn the lights off completely. That’s a personal choice. I can say reliably that they do make a huge difference because the size of my largest cannabis plant exploded in just two weeks after more than a month under ”economy” lights. The light distribution seems to be very even. (I’ll update this review once I test the par map). So far, I am incredibly impressed with performance of the factory tested par map and I’ve not seen another manufacture with this uniform of a par map at this price and size. They use quality genuine Samsung LED’s and a Sosen driver. They are not the 301b or 301h LED’s, as far as I know, but I personally don’t care. Efficiency isn’t an issue for me as I am a small grower. My main concern is performance and these lights more than accomplish my performance goals 10 fold. Instillation is fairly easy. A few screws, a couple hooks and 2 ratcheting pulleys later, you’re done. I like the dimming options available, however my only issue here is that the nob does not line up well with the section your dimming. I actually count the steps from %0 to be certain I am at the desired level. I don’t know if it’s a defect or if they are deliberately made that way. I have no way to take my lights down and send them back for an exchange anyhow. I highly recommend these lights for a 2x4 grow or two of them for a 4x4 grow. If you know what you’re doing, they treat your plants right. Start by dialing it back one notch than recommended in the manual. Dial it up as needed according to plant performance or size. Little ones are very sensitive until they have a few nodes for the most part. Make sure you buy a good temperature/RH meter so you can spot test your plants and their locations individually to ensure the climate is correct for your variety of cannabis your growing. Not all cannabis varieties like the same conditions. If you’re growing other things, I would still say the same. Install the drivers outside of the tent to reduce heat and make your tent is well ventilated with a solid exhaust system. For anyone wondering about the more technical aspects, my entire system runs at less than 5 amps. Home break box 15amp circuits can handle that just fine if you aren’t running it on a circuit with a TON other things or anything heavy duty like an appliance. My a/c is on the same circuit with it, for example, giving me a total circuit load of approximately 9amps. If you prefer to be able shut them all the way off, grab an inline switch from Amazon for like $20. It’s an easy and cheap solution. I bought two 3 foot green light up ones from Mestek that plug directly into the power supply and split off, giving me an independent switch that is still technically inline. The driver plugs directly into the switch which is plugged into the power supply. I hope this helps anyone considering these awesome lights. I wish more growers would see how much value they have as they are superior to almost every other light out there in this size category. They absolutely outperform them based on my experience and homework. And I have done a ton of homework. Happy Growing! EDIT: One year later and they are still going strong. Tested the par map and color spectrum with the Mammoth Lighting spectrometer/par meter, and the given par map in a 4x4 space is confirmed accurate. These were the old XS2500pro lights which now have been replaced by the XS3000pro lights. They look nearly identical, but I have not personally tested the XS3000pro lights.

I was looking for a small LED grow light to supplement lighting for the end of a 5-foot shelf since most lighting will cover only 4 feet. This small plant light is almost overkill for my lighting needs on this shelf. This light is extremely bright when set to 100%, but most important is the quality of the light which is measured with a PAR meter. This light is on a shelf that I am growing cherry tomato bushes which require full sun for at least 12 hours. I have found the PAR levels for this light to be far superior to other small LED lights I have had. So, what do I like about this grow light? 1) In addition to being very bright, the PAR levels produced are excellent. When set at 50% and 13" above the plants, the PAR level is 747 which is more than enough for the cherry tomato plants. 2) The intensity of the light is easily adjustable with a dial on the end of the light. This mean that the intensity of the light can be adjusted for seedlings, or small to large plants without having to adjust the height of the light. If you prefer to adjust the height of the light, pulley are included with this light. 3) The cord length is plenty long to reach an electrical outlet and an extension cord can be used to extend it. 4) This plant light works perfectly with a timer. 5) This light can be daisy chained to another light to cover larger areas which eliminates the need to find an outlet for each light. 6) A supplied dimming cable can be used to control the light intensity of all lights on the chain from one light. 7) The light from this plant light penetrates the leaf canopy to encourage new plant growth below the canopy. 8) This light is extremely easy to set up and use. 9) This light provides more consistent PAR readings even on the outer edges of the lighted area. I am currently using 3 of these lights on a 2' x 5' plant shelf to provide lighting for bush tomato plants, and have installed them so the longer side is perpendicular to the side of the shelf. So this light sufficiently lights the 2' width of the shelf. By spacing them on the 5' shelf, the crossover lighting of the lights equalizes the lighting to the plants. Considering the height of these plants, I have all of them set at 60% which saves on electricity. Since these light penetrate the plant canopy, I am seeing a lot of new growth on the plants within a couple of weeks. I hope this review was helpful for you.

Well built, sealed construction, highly adjustable spacing between the lights with several inches of adjustment. Runs nice and cool and high PPFD. Best band for the buck I could find for a 6x3 custom grow space.

Produto bom de alta qualidade agora só falta eu testa e também faltou vcs colocar o xs2000 pra eu pegar também

I've purchased a ton of LED lights over the years with varying results some were really bad, most were just okay The VIPARSPECTRA XS1500 Pro is a on a different level. From the moment I opened the box I could see the superior quality, every aspect of this light is beautifully constructed with an attention to detail. You can tell right away this company cares about what they're doing. But what's really important is the function & the XS1500 above and beyond any other light I own in this regard. At 40% it's almost too bright in my 2x3 indoor greenhouse outshining my other lights cranked to 100%. The light distribution is also superior with plants at the edge of the grow space performing just as well as those in the middle. This is probably down to the New-Gen lenses I actually asked an AI to compare this to similar lights in both wattage & price range & the AI consistently insisted this light was superior due to the high quality diodes (likely samsung) and the lenses making for higher light dispersal & efficiency which actually makes the light cheaper overall if you factor energy usage into the price to own over 6 months. I definitely recommend this light (especially for the price) you will not be disappointed.

Me acaba de llegar la tengo en un espacio de 1x1 se ve bien ya veremos cómo continúa la cosa algo a considerar es que si genera algo de calor, pero es normal

Luz mais uniforme do mercado para 60x60, Construção impecavel.

Okay, I've had one of these lights for 4 months now and just bought another one a week ago. In a word, they are AWESOME. Couldn't be happier. Like others here, I researched a lot before I bought the first one. Started off with an Aglex G110W ...a nice enough light, great quality but not dimmable, then bought two Topsun TS-1000s...also nice enough, but the misrepresentation in the ad made me keep one and send the other back (the picture makes the heat sink look much thicker than it really is). Plants like them and the price is right, but the thin heat sink makes them run pretty hot at full brightness. Finally I decided to get serious and look at higher-end lights, 1000 watt equivalent. Spider Farmer had the right specs but I didn't like the (relatively) low number of diodes; they must be over-driving them to get that level of brightness. Mars Hydro had lots of diodes with good brightness but they were cheaper diodes. Neither really impressed me for the price. Then along comes Viparspectra with a brand new 1500 watt unit, which not only has excellent specs but top-quality name brand diodes and drivers as well. (and even better, the price for this 1500 watt is about the same as Spider farmer and Mars Hydro want for a 1000 watt!). Three things stand out: 1) Plenty of diodes...360 of them, and Samsung LM301Bs (currently the best available, and the ones that all others are compared to). 2) A Meanwell LED driver, which is again the one all others are measured against...but not just the XLG series as provided in most quality lights. No, this is an HLG series...the best of the best. 3) A *real* finned aluminum heat sink. With quality components like these, you just can't go wrong. This light is a beast...I actually sunburned a tropical plant from 18 inches away before I figured out what was happening (and that's after giving them a few days dimmed down to acclimate); I had to raise the lights to 25 inches (and dim them) to compensate for all that power. I have these lights hanging from a 48" wide 6 foot tall wire shelf, and even without fans, at 100% output they are still far cooler than the Topsun light was (yes, the XS1500s get hot...but not so hot that you can't touch them).. Since heat is the enemy of all electronics, though, I run two 120mm 5 volt computer fans blowing air gently over top of them, which they don't actually need now that they are 75% dimmed. The fans are cheap and available here on Amazon, and come with a 120 volt power supply to plug the USB into. They are *totally* silent on the lowest speed and even when the lights are at 100% they are now just lukewarm to the touch. They will last for years. The dimmers are silky smooth and well positioned; they aren't daisy-chained but I don't need that with only two of them side-by-side. If I absolutely had to nitpick, though, my only complaint would be that the 1000 watt version was *nowhere to be found* when I bought the first 1500 watt one (not even on their website)...not even a mention of it. My fault for being impatient, I guess...I should have waited. No regrets at all, though. It's better to have excess power and not need it, than to need it and not have it. BUY this light. You'll love it as much as I do.
