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.

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.

I've purchased multiples of these lights and had them running 12 hours a day for two to three years and they just keep on running like champs. And they are BRIGHT, just like you want them to be. What I use them for: orchids, staghorn ferns, carnivorous plants, succulents, cacti, ginger during the winter. I basically have a greenhouse but it's a room in the house. Everything I put under them just grow s like crazy, especially in the NW where none of these things would grow well here in the deep woods. Quality: These have been bulletproof. I've moved them around multiple times as plants have gotten rearranged and they keep on truckin. No burnt out diodes, no diminishing light intensity, PAR levels are as they describe. Adjustments: The clips make it easy to hang on the system I made after getting rid of the bakers shelves (which was also an easy solution). They're also easy to adjust the height. The dial allows the light internist to be turned up or down in 20% increments which is always nice. Heat output: They definitely do get a little warm, but not scalding hot like other types of growlihhts (non-LED). I do have a few other brands of LED growlights from before I discovered these and the heat output is on scale with the increased wattage. I get these on sale occasionally so they've been a perfect addition. I haven't daisy chained them together yet because they tend to be spread out across the room, but on a Bluetooth timer wall plug, they've been perfect to let me enjoy a hobby in a place where it never would've been possible.

This is a very sturdy light. The hardware to hang it is nice, especially the ratcheting pulleys; they make raising and leveling the light very easy. The light is obviously meant to hang from high above, which did not fit well with my idea of using a small grow tent. I ended up having to buy a 63" tall grow tent instead of the 48" tall one I wanted solely because it was too difficult to hang the light high enough in the 48" tall tent. It works great in the 63" tall tent. As for light output, I did some experiments with an uncalibrated phone PAR meter app. I tried the light fairly close to the target (plants) with 40% power on the dimmer vs farther from the target at 100% power. At the lower power setting, the amount of light hitting the target dropped off severely from the center of the light footprint out to the edges. For example, if a plant directly under the center of the light was getting a nominal 350 PAR (PPFD), plants a foot to the side of the center of the light were getting only 85. But with the light further away from the plants but at 100% power, there was very little difference between the light being received by plants directly under the light vs plants off to the side of center. I was very pleasantly surprised with how evenly the light power was hitting the plants. A plant directly under the center of the light was getting 350 PPFD, while a plant out at the edge was still getting about 320 PPFD. The one thing that nearly caused me to give it 4 stars instead of 5 is that there is no way to turn the light off except unplugging it. It has a dimmer control, but even at the lowest setting the light is still on. I wish they had used a dimmer control that had OFF as the lowest setting. Overall I'm very happy with the light, and I'm sure my plants will be as well.
