Features

  • 2024 Upgraded TSW2000 LED Grow Lights: Experience the advantages of our new diode layout, densely packed in the center and sparse on the sides. This arrangement creates a more uniform light distribution between the center and sides, ensuring the most even PPFD distribution and maximizing plant yield. These meticulous design details make the TSW 2000 300W grow light ideal for any stage of plant growth in 3x3ft for flower and 4x4ft for veg.
  • Wider Range & Stronger Light: The 120 angle white reflector design on Mars Hydro TSW2000 led grow light is patented, allows for wider coverage and increased light intensity, aiding plants in better light absorption. Boasting an actual power of 300W, the TSW2000 delivers robust performance, while other model 2000 from other brands only delivers 200 watts or less.
  • Dimmable and Daisy Chain: With an independent dimming button on the external driver, this growing lamp allows you to adjust the brightness from 0 to 100% according to the specific growth stage of your plants. Additionally, it supports daisy chaining of up to 50 LED lights, seamlessly connected in a chain. The auto-sensing power supply is compatible with 120VAC, 240VAC, and 277VAC, making it suitable for both large-scale setups and personal settings.
  • Save Money and Energy: Mars Hydro's advanced SMD LED technology offers the highest PAR/LUMEN output while consuming only 300W with 704 LEDs, resulting in up to 50% energy savings compared to other grow lights for indoor plants, providing an additional 60% return compared to old HPS/MH lights.
  • Sunlike Full Spectrum LED: TSW2000 full spectrum growing light features 730-740nm Red IR/3200-4200Knm/5200-6800Knm spectra, providing the best light for all plant stages. Rapid plant response from seed to flower, and an increase in yield and crop quality.

    • Great budget spec lights

I have these In a 2x4 grow tent and the size is perfect. The color of light they produce is spot on and I have not witnessed any flickering. I have them plugged into a Vivosun e42 controller and they function perfectly! The heat generated is not too bad considering it is a 300w light in a 2x4 tent. Super easy to use and set up! ... show more

    • Great Quantum Board LED Light - Seems Better than Standard LEDs
Size: 2 x 4
I have had this light for about two weeks now. The light appears well made and comes with the normal hardware for hanging plus a timer and temp/humidity sensor. I would have preferred those to be an option since I have them already and suspect most growers do as well. For first time growers it's a nice package deal. I have six 3-4 week old plants under it at about 18" and four under a 1500 watt LED and there is a noticeable difference in growth on the plants under the Mars Hydro. I recently purchased a PAR meter and my measurements show an average 20-30% PPFD increase over what I was getting with two 1500 watt LEDs over the same plants at a reduction of close to 150 watts power consumptipon. And the overall coverage is better too. It also generates much less heat than the other LED lights and the silent operation is nice too although the noise was not really an issue for me, but not having fans that can break is a plus. I am considering purchasing another one, but might wait to see how this grow turns out. I am curious to see how well it does in the flowering phase. It is a very energy efficient light over traditional LEDs producing more light for less wattage, which I verified with a new watt meter I recently purchased. However, that is not the reason I purchased this light. That said, I have seen some reviews that suggest the standard two and three chip LEDs are still superior overall to Quantum Board LEDs and if energy saving is not a concern, they are still the way to go. The numbers don't show that to be the case based on my measurements and results so far, so I guess I will know if this is correct about three months from now. It came pretty well packaged in a sturdy box with some wood to provide added support. I did have an issue with one of the drivers not dimming properly and contacted support. They were very responsive and are shipping me a new driver, although I have to wait a month as they are currently out of stock, but they did give me a $10 discount for the inconvenience, which was cool. My initial impression is these lights are better in many ways to standard LEDs and are a very affordable alternative. I am guessing Quantum Board LEDs will likely replace standard LEDs over time. I will know more in a few months and may update this review. If all goes well I will be transitioning to all Quantum Board LEDs. Just not sure yet if they will all be Mars Hydro lights. For now, I can recommend the Mars Hydro TSL series lights without hesitation. Good choice for a first time grower too since you get a lot of bang for your buck. Update Jan 27th Just completed my grow with two of the Mars Hydro lights. Very impressive growth with the new lights. So much so it caught me off guard how much the plants stretched when the light cycle was moved to 12/12. I was not prepared and could have done a lot more bending. I ended up with some light burn trying to get the light at the optimum height. Also, I had two plants under one of these lights and it was just too much light for one plant making it difficult to take advantage of the light output. The next grow I will be using the light with one plant and do a better job mainlining to get more yield from the light. That said, the yield I did get was pretty amazing. Very dense and frosty buds for sure. So some lessons learned. My plan now is two purchase two more of the TSW2000 model which will work better in one area of my room over one plant. That will give me a total of four Mars Hydro lights eliminating all of the standard LEDs I have, yet consuming a lot less power. About 1200 watts versus in excess of 2000w with the Mars Hydro's and standard LEDs. I am pretty jacked about the next grow and can say for sure these lights are worth the money - they will pay for themselves over time compared to standard LEDs and that is fact based on real data. Highly recommended - you will not be disappointed with the purchase of these lights. ... show more

I. The Mars-Hydro TSW2000 arrived well-packaged absent any damage. I have heard growers report their lights arrived dented or bent, and I believe them. For this particular line of LED lights the manufacturers decided to use a thin metal for the reflector as I'm sure this allowed them to cut costs without sacrificing the light's efficacy. My light, however, arrived with its vulnerable edges protected by rigid Styrophoam. My light came with a timer, which would have been extremely welcome had I not already owned one from prior grows, as well as a pair of ratchet hangers. It's always nice to have a fresh pair of hangers since they seem to be universally made from crappy alloy, which rust after one or two grows. The assembly instructions were unclear. At first, I was a little dismayed to see the instructions did not have a step-by-step breakdown. It was basically three illustrated panels with almost no annotations. Fortunately, this is not rebuilding a jet engine. If you just sit back and study the parts for a few minutes you'll realize there aren't too many ways it can go together wrong, but you'll want to pay attention to how you orient the drivers for optimal cable management. Once the new light was installed and turned on to full power, it filled my 3x3 tent with a nearly blinding level of light. This is obviously a meaningless way to judge the efficacy of a light, but nonetheless I was glad it worked and wasn't DOA. My Equipment: 1. 3x3 grow tent 2. Mars Hydro TSW2000 3. 4" 190CFM Exhaust Fan w/ charcoal filter 3. 4L Humidifier 4. (2) 6" clip fans 5. Four 3-gallon nursery pots (sturdy pro-cal type, might even be pro-cal brand) I drill extra holes in the bottom FYI. 6. Digital light timer II. Some additional info for grow enthusiasts: 1. I direct sowed into 3-gallon pots* and used no seed starter or rooting solutions. 2. Seeds planted are a 3-pack of Blue Dream Autos and my last Gorilla Glue Auto seed. I only water the immediate area over and around the seed, wait for it to almost dry up, and then gently water again. All four girls popped by the end of the 4th day. I am 20/20 sprouting seeds in this fashion. Finally, and very importantly, during the seedling stage I set the light at 75% and kept the light 30" above the pots. Any lower or any stronger and they would have suffered heat stress. *Pro-Cal pots with four extra holes drilled through the bottoms for additional drainage. Soil Used: 75% Roots Organic Original, 25% Coco. I find that Roots Organic Original already has enough perlite. I'll add to this review once the plants are leafed out some. III. I am currently mid-way through veg and all four plants are doing very well. I can now confirm that this light is quite strong, and is more than what vegging plants need in a 3x3 tent. At 24" and 100% power the tent climbed into the mid-80's (it's very hot where I live right now, even in the basement, so my extraction fan was a little overwhelmed I think). To remedy this I lowered the power back to 75% and the plants seem to prefer it. I had edge curling on the leaves of one of my plants before backing off the brightness, but that has ceased. At this hanging distance and power level there is zero stretching and their growth has continued unabated. I'll update this review during flower, and again, one last time, to report yield. IV. Plants are now in mid flower and have stopped the pre-flower/early flower stretch. I still consider myself only a late-beginner/intermediate grower, having only grown 20 plants so far, including these, but so far these plants have the best internodal spacing of the plants I've grown. Up until now I've used only two different burple brands--and they've worked--but they tend to invite stretching because their wattage and spectrums were not ideal. If anything, these lights are inhibitory for stretching because they include plenty of blue light and at least in my case, for my current phenos, the light is strong enough so the plants don't want to get closer than they have to. This has made for some pretty compact budding sites. I'm excited to see what the colas will look like in another few weeks. The TSW2000 is obviously strong, and provides a nice, bright sun-like spectrum. I believe it will prove out to be an ideal 3x3 tent light, as it is clear now it would have completely flowered all 9 square feet of my tent if I had added a 5th 3-gallon pot, which I plan on doing next time for sure. How big will the buds be? How much will its dry weight end up being? Only time will tell! I'll add a final section to this review once it's all chopped, dried and weighed. V. My four plants have been chopped, dried and cured. The yield of each plant was fairly uniform around 2-2.5oz. Total yield was 9.6oz of buds. Popcorn buds would push it to 11 most likely. The Blue Dream'atic potency was subjectively believed, by two different heavy cannabis users, as slightly stronger than the Gorilla Glue Auto, but both were considered quite potent. I barely smoke so of course both were quite strong to me. I generally only do edibles. Conclusion: This light is more than adequate for the home cannabis grower, and an excellent upgrade for anyone currently using old-school burples or other lesser grow lights. ... show more

    • This light is awesome.
Size: 2x2 100w
I have just gotten into growing indoors and had some cheaper lights that worked; but I was getting very slow growth on my culinary herbs. I got this light in hopes that it would stimulate growth and healthier plants. These were brought inside from outside because they needed TLC. The Mars light is working wonderfully on a timer connected to ge cync smart plug. The full spectrum is helping my herbs come back with a vengeance. My basil is going bonkers, my thyme is taking off and starting to get big, my oregano is growing well but is going slower then the other two. Time will tell on the oregano. Thank you Mars for a good led full spectrum light that is inexpensive as well. I got it for $54 on sale and now it is $58 so not a very big investment to grow a few herbs indoors. My other lights will be used to start seeds and clones. ... show more
