Features of TSW2000

Click to check more details

Great Budget Grow Light For Beginners:

Consuming 300 watts and providing 776 umol/S of PPF, TSW2000  LED grow light has the ability to replace a 450w HPS light, while reducing 40% power intake. *Match with 120x120cm grow tent , 6 inch fan with carbon filter kits

Unique Reflective Aluminum Hood:

Mars TS lights use highly reflective material with a refraction angle of 120° as the quantum board. It can cover a wider reflector range to enhance its light intensity and effectively reflect the scattered light back to the plants, which increases the light utilization rate by 25%, allowing plants to receive more energy without burning them for maximum headroom.

Dimmable & Multi-Connection Features:

By turning a dimmer knob, TSW2000 is more convenient for growers to adjust the brightness from 0% to 100%. The daisy-chaining feature helps growers who have multiple grow lights to manage their lighting settings better. Up to 30 lights can be connected and controlled by one master lamp.

Marvelous Luminescence:

The luminescence of TS grow lights is similar to HID’s, to meet the needs of growers with HID grow lights perfectly. Meanwhile, Mars Hydro TS led grow lights have high luminous efficiency. The PPE (Photosynthetic photon efficacy) of TSW2000 is as high as 2.6 umol/j.

Full Spectrum LED Grow Lighting:

Mars Hydro TSW2000 is a full spectrum grow light that emits all of the light in the wavebands of 400nm-700nm, which is known as “PAR”, excellent for Photosynthesis. There’s extra infrared light (730-740nm) added to promote flowering for better harvests.

No Fan Design, No Noise:

Mars TS Series lights apply a whole layer of aluminum heatsinks to disperse heat quickly instead of noisy fans. Passive heat management achieves optimal heat dissipation without the worry of broken fans. The drivers of TSW2000 is removable with a 2-meter-long extension cord so growers can put the driver outside the grow tent or grow room which helps lower the growing room temperature.

Safety Certified & Excellent Customer Care:

All Mars Hydro LED grow lights have been CE, ETL, RoHS, and UKCA certified, safe to use worldwide. Mars Hydro officially guarantees 24 hours customer service, a 5-year limited warranty, and local warehouses & repair centers to offer the best after-sale services to growers around the world.

    First time grower. Started with this newbie light and have had it running about 18 hours a day for the past few months. My plants love it, it hangs comfortably and the light is even and adjustable.

    This design is incredible! You most certainly know how to keep a reader entertained. Between your wit and your videos, I was almost moved to start my own blog (well, almost…HaHa!) Great job. I really enjoyed what you had to say, and more than that, how you presented it. Too cool!

    I changed out all of my lights to Mars Hydro TSW 2000 and have not looked back. Everything is going great.

  13. Tom – 21/04/2023

    Rated 5 out of 5

    Love the efficiency of this LED; have had many successful grows and harvest since switching to Mars Hydro

  14. Dave (Grower) – 19/04/2023

    Rated 5 out of 5

    The designers of this light should be very proud. There are multiple options for where to fix the drivers which give off a reasonable amount of heat. This is hugely beneficial for growing at varying times of the year. If your tent needs heat you can fix them to the top of the light. If heat is an issue you can fix them to something outside of the tent (I screwed them to some MDF which sits nicely on top of the tent supported by the frame). This massively reduces the fluctuation in temperature when the lights are off.
    The coverage area for flowering is 3’x3′ which is double the area of my previous light and uses the same amount of electricity, so twice as much yield for the same cost! Another highlight is the 100% dimming functionality (others sometimes have limited/incremental dimming) so you have total control of intensity. I wholeheartedly recommend this light but particularly for anyone struggling with heat issues.

    Love the mars hydro products especially this ts1000. I wish I could get the ts2000 or fc3000 .

    If the ts1000 dose amazing with the yields and denz of the nugs what would they do.

    Hi there thanx again Mars hydro ordered my Tsw2000 late evening 25/10/22 order processed on 26/10/22 arrived dinner time 27/10/22 all good no dings or dents hooked it up and everything worked just as it should was a great improvement on my old ts1000 which I’ve had for over a year now still going strong just not big enough for my new tent I can see a difference after 24 hours tried other lights in the past but think I’ll stick with Mars hydro

  19. Steve (Grower) – 07/09/2022

    Rated 5 out of 5

    I bought two of the TSW 2000 lights. I was rather dubious as to their performance being as good as HPS lights, but after seeing one light perform, I soon bought another. Hard to believe but two 300 watt TSW have produced better results than two 600 watt HPS. These lights are the future. HPS is old hat now

  20. Morgan (store manager) – 12/03/2022

    Rated 5 out of 5

    Was super easy to assemble and set up. Plants are thriving under this light and it doesn’t out off as much heat as my other one. The light color is more on the warm side which will be great for growing!

  21. B H (store manager) – 01/03/2022

    Rated 4 out of 5

    I’ve tried different lights before, which i thought were good enough and doing a pretty good job.. I decided to buy a new tent and wanted something of quality, so I bought a Mars Hydro 4×4. Well now that I have a new tent, I have to buy a new light, so i decided to go with the Mars Hydro TSW 2000. The first two days my girls under the new lights I started to notice quick growth spurt and fuller. They absolutely love the brightness. This light definately mimics sunlight. I started the light at 75%, then after a few days cranked it up. All is good! I’ve recommended this light to another grower already

    Wow, lights up my whole 3×3 tent, two or three would flower in that tent saving 600watts of power, so basically if I where to get one more of these , the savings would pay for the lights in o e year compared to 1200watts HPS, I’ll see how they flower, ifthey flower as good as I have with HPS, it’s a done deal, switching over completely to these lights

    Product was packing seemed well but both short sides had a little dent I assume just how it is from forming the reflector so I’ve ignored that, i added this light mid flower in the end I recieved a very good yield that was very dense and completely crystallized, looking forward to a full round with this light and definitely considering a 2nd

    Rated 5 out of 5

    Absolutely love the fact that I can put the drivers outside the tent greatly reducing heat in there even though the top of the light still remains warm to the touch. Also they should update the instructions to show how you can hang it without the drivers. Those little aluminum clamp looking things at each end you can hook just the wire take off the actual hook itself and Bam works like a charm!

Q & A

Ask a question
Would this fit in a 2x2 tent John asked on 23/12/2023

2x2 size is not suitable, it can be used for 2.3x2.3, 2.5x2.5, or 3x3 tents
