List Of The Best Mars Hydro LED Grow Lights

1) Mars Hydro COB 100 watt LED Grow Light

    Mars Hydro offers a CREE powered COB LED light in 100 watts. In case, like me, you were unsure what COB stood for, COB is short for Chip-on-Board. 

    This Chip-on Board packaging technology describes the mounting of multiple LED chips onto a surface where it forms a single module. 

    This process has tiny LEDs wired and packaged together into a single ceramic or copper board, and they function as a sole light source. 

    CREE's are super high-performing, energy-efficient LEDs that provide a crisp output. When you combine those two, you get a superior growth light. 

    Important to create a trouble-free operation, the Mars Hydro COB light has an IP65 enclosure that has complete protection against particles and water. 

    This is especially important in a growing environment that has a lot of moisture. 

    Using Meanwell drivers, CXB-3590 COB diodes, there are supplemental red and blue spectrum diodes built with Osram and Cree chips. 

    The addition of a fan radiator helps to keep the area you are growing in cool and quiet.

    2) Mars Hydro Mars TS 1000 Quantum Board LED Grow Light

    A compact grow light, the TS 1000 has, at the highest intensity, about 590 uMols. That is exactly what you need for the vegetative phase. 

    It has a simple design and is a full dimmable spectrum LED grow light.  While the TS series of grow lights are basic, they are a quality product at a budget price. 

    This set of lights features a white light spectrum. Current thought believes that a white spectrum to be better than just red or blue alone. 

    The TS 1000 maintains a strong intensity at the edges. The TS series are all quantum board style fixtures. 

    Using Epistar 3030 chips, the efficiency of these lights will save you in the cost to run them. The TS 1000 will cover a 2' X 2' area when hanging at a lower height as in the blooming stage. 

    The recommended distance to hand above your plants is: seeding: 24", germination: 24" - 30", vegetation: 18" - 24" and bloom at 12" - 18". 

    You can add to these lights so that you could start with one or two and add as your budget permits.


    • Actual Power: 150W+/-5%@100--277V
    • Coverage:Veg:3’x3’(90x90cm); Bloom:2’x2’(60x60cm)
    • Compared to HPS/MH/HID:250W

    • PPE:2.1--2.35umol/J 


    3) Mars Hydro TSL 2000 Quantum Board LED Grow Light

    Suitable for plants in all growing stages, the Mars Hydro TSL Quantum Board LED grow light will make your indoor growing easier. 

    The simple and efficient design of this grow light consists of two long LED boards and an aluminum reflector and two drivers. 

    At a length of 40 inches, this grow light fits nicely in a 2 X 4-foot tent. The length will put the light directly above the majority of the tent space. 

    Other LED lights employ cooling fans that reduce the efficiency of the light and add to the energy costs. 

    The Mars Hydro TSL is fanless. The design of the light allows the heat to passively dissipates off the light. 

    With fully dimmable drivers, these dimmers are conveniently on top of the ballast. 

    Other versions of grow lights require you to unscrew the ballast to dim the grow light, but the TSL makes it easy for you to dim the lights.


    • Actual Power:300W+/-5%@100--277V
    • Coverage:Veg:3’x5’(90x150cm); Bloom:2’x4’(60x120cm)
    • Compared to HPS/MH/HID:450W
    • Average Yields: 1.5g/W
    • PPE:2.1--2.35umol/J

      4) Mars Hydro TSW 2000 W Quantum Board LED Grow Light

      The TSW 2000W LED grow light is an upgrade compared to lights that are only a few years old as the TSW provides the full-spectrum indoor plants needed to thrive. 

      While similar to the TSL, the difference between the two is that the TSW adds more coverage area. 

      The wider quantum board configuration is 3 X 3 feet during the flowering stage. This size makes it perfect for a 3 X 3 grow tent and easy to install. 

      When considering a PAR perspective, the TSW has a balance of natural white light, and it also has a mix of red and blue lights.

      With a PAR value at about 910umol, this lighting spectrum is great for plants to grow in. 

      Being a solid unit that emits little heat the TSW does not have fans. It does not need them because of the quantum board technology. 

      This makes the TSW very quiet. On the TSW, an angled stainless steel housing redirects lights towards your plants, increasing the efficiency of the light. 

      As safety dictates, don't look directly at the light unless you are wearing protective eyeglasses. 

      The TSW has a dimmable feature in case you need to adjust the intensity in the various stages of growth. 


      • Actual Power: 310W+/ -5%@ 100--277V
      • Coverage: Veg: 4’x4’(120x120cm); Bloom: 3’x3’(90x90cm)
      • Compared to HPS/MH/HID: 450W
      • Average Yields: 1.5g/W 
      • PPE: 2.1-- 2.35umol/J


      5) Mars Hydro TS 3000 Quantum Board LED Grow Light

      Wanting to design a better full-spectrum light, Mars Hydro created the TS series of lights and this particular board is a 3000-watt level. 

      The TS 3000 has an improved quantum board along with a heat reduction cooling system. The light consumes around 450 watts without the need for built-in fans. 

      While this is valuable at all stages of the growing cycles, the TS 3000 does an exceptional job during the bloom phase. 

      This particular grow light is also suited for use in a commercial setting, or for the person who wants the optimum performance from their grow lights. 

      What is nice about this light is that Mars Hydro has put this quality within reach of the average grower. It is much less expensive without sacrificing quality. 

      It;s fan-less and therefore quiet light, the reflector on the light reduces the light's heat output. 

      The light's aluminum structure also does double duty to intensify the light output by about 20%. 

      The TS 3000 uses a full wideband spectrum that mimics natural sunlight. This makes the light ideal for growing different types of plants. 

      The best growing area for the TS 3000 is 5 X 5 feet.  From seed to harvest, the TS 3000 can deliver the light needed at each stage.


      • Actual Power: 450W+/ -5%@ 100--277V
      • Coverage: Veg: 5’x5’(150x150cm); Bloom: 4’x4’(120x120cm)
      • Compared to HPS/MH/HID: 800W
      • Average Yields: 1.5g/W 
      • PPE: 2.1-- 2.35umol/J


      6) Mars Hydro SP-150 Quantum Board Full Spectrum LED Grow Light


      One of the advantages of the Mars Hydro SP-150 is its ability to perform in an ultra-humid environment. 

      The LEDs are protected from moisture, making the light waterproof. This feature also extends the life of the SP-150. 

      The SP-150 uses white SMD diodes from Epistar, so these lights are very similar to quantum board lights.  

      They also added IR and UV diodes to help round out the spectrum in the areas that all-white LEDs can fall short. 

      This results in the optimum spectrum for every stage of growth. 

      Mimicking natural sunlight and adding red and blue light means that your plants will be getting all of the colors of light that they need the most. 

      The Epistar diodes have a dimmable driver with about 245 watts at full power. 

      This light will achieve a PPFD of 944umol when you hang the light 12 inches from the canopy in a 2 X 4-foot coverage area. 

      When in the vegetative stage, hang the light at about 18 inches, and it will achieve 632 umol. 

      The rectangle shape of the SP-150 can be an advantage when you have several rows of plants or if you stack your plants vertically. 

      The light's rectangle shape allows you to install the lights directly above each row and not waste the light by illuminating aisles, as square lights will do. 

      With a fixture of this shape, the light does not have to travel as far to reach the outsides of the coverage area and therefore does not lose as much intensity.

      • Coverage: 2'X2'
      • Max Yield: 1.8g/watt
      • PPFD: 387 µmol/m²s
      • Replace HID/MH: 250w
      • Draw Power: 134W + - 5%@AC120V  138.9W + - 5%@AC240V


      7) Mars Hydro SP-3000 Quantum Board Full Spectrum Grow Light

      The Mars Hydro SP-3000 can be a more user-friendly light with its daisy chain capability. 

      With this ability, you can plug the power cord into another SP-3000 light instead of having to run the cord to a power outlet.  

      There is also an easy dimming knob on the unit. The SP-3000 uses high-quality Samsung and Osram LEDs. 

      Use this light to cover a 4 X 5 foot grow area in the seedling and vegetative phases of growth. Mars Hydro uses ultraviolet wavelengths in its light spectrum.

      The rest of the range is made up of 3000 Kelvin white that includes red wavelengths for flowering and blue wavelength s for seedling and vegetative stages. 

      You can use this as the main light, or even as a sidelight. It can be mounted horizontally or vertically. 

      The no fan design has a powerful heat sink, so it is a quiet grow operation.

      Brief History Of Grow Lights

      The first light-emitting diode (LED) was developed in 1962 and was a red light. 

      In an application concerning plant growth, NASA (National Aeronautics and Space Administration) used LEDs in 1988 for its space-based plant growth investigations. 

      It was not until 2000 in Japan that the commercial use of LEDs for plant production paved the way for their use for personal growers. 


      LED Lights Work Great For Growing Indoors

      Today, grow lights have become the most crucial element of an indoor garden. It does not matter if you are a seasoned grower or if you dabble now and then. 

      You still want equipment that is going to deliver a quality product for your effort.

      The light that you choose to grow your plants will be the single most crucial item essential to your indoor garden. 

      Lights are the way that you will develop your plants from start to finish. 

      You will use grow lights to start your seeds in preparation for planting. Grow lights will also extend "daylight" hours for your plants.

      Light Spectrum

      As an indoor grower, it is important to know a few basic concepts about lighting in general so that you understand how light affects your plants. 

      When you know this, you will also be able to see what makes a particular type grow light more suitable for your goals. In turn, this will save you time and money.

      Light, both visible and invisible, falls in a range somewhere on a light spectrum. Spectrum measurements are nanometers. 



      These nanometers correspond to the wavelength of light. As an indoor grower, you will need the 400 - 700-nanometer range. 

      The Importance of PAR

      Photosynthetically Active Radiation, or PAR, reflects the spectrum of light that plants need to grow.

      We all know that photosynthesis is critical to your growing plants. 

      Photosynthesis is the process where plants use sunlight to synthesize food from carbon dioxide and water. 

      PAR refers to the wavelengths of light that plants can use for all of its needs regarding photosynthesis.


      The Grow Range For Plants

      Within the main 400 - 700 nanometers range, there are ranges that plants use for specific purposes.

      400 - 490 nanometers: this is the “blue” light range that plants use during their vegetative growth stage

      580 - 700 nanometers: this “orange-red” range is used by plants when they are in the flowering and fruiting stage.

      Just in case you want to know that happens in the 490 nm to 580 nm range, that is the range that the chloroplasts in the plant cells reflect green light, and with our eyes, we see the green in the 510 - 570 nm range.


      The Advantage of LED

      There is a variety of grow lights on the market. High-Intensity Discharge (HID), High-Pressure Sodium (HPS), Ceramic Metal Halide (CMH), and Fluorescent.

      Surpassing the use of the above lights is a relative newcomer, the Light Emitting Diode (LED)

      LEDs are very popular with indoor growers because they have benefits other lights can’t match. 

      An LED uses an extremely low amount of energy while putting out very little heat. 

      This is a tremendous advantage for indoor growers who usually don’t have the space to deal with a lot of heat output. 

      LED bulbs degrade far slower than any other type of bulb. For example, an incandescent bulb will degrade in 6 - 9 months, while that same LED bulb will take 15 - 20 years. 

      LED lights have this advantage:

      • Take less energy
      • Last longer
      • Smaller
      • Solid-state, so more durable
      • Produce lower heat 

      In Conclusion

      With the time, effort, and money you put into growing plants indoors, you want to know that you are getting the optimal results.

      Mars Hydro's selection of LED grow lights will enable you to successfully take your indoor plants all the way through their life cycle and ensure you of a productive harvest.

      What's The Difference? Aquaponics Vs. Hydroponics 0

      If you are wondering how it all works, like I was, here is the low-down on aquaponics.

      Aquaponics is a system of aquaculture. The waste produced by fish, or other aquatic animals, supplies nutrients for plants grown hydroponically, which means in water, not soil. 

      The Best LED Grow Lights 2020 0

      Light-emitting diodes (LED) have been around for over 50 years, even though it may seem as if they are a new technology. 

      This is because it has only been in recent years that the advantage of using LED light has been noticed by both professionals and enthusiast growers.

      There are several reasons why LED grow lights are so popular. A big plus for LED's is that they are energy efficient. 

      LED's are up to 75% more efficient than incandescent lighting, and last about 25 times longer.  That is a big plus!

      Other advantages of LED light are that they:

      • Can stimulate growth in plants
      • They have adjustable wavelengths
      • They are energy efficient
      • They are compact in size
      • They are very durable and long-lasting

      Things To Consider

      When looking for a set of LED lights, it is best to get a set that is quality and will suit your needs. 

      If you choose a set based solely on a lesser cost, you may end up with a product that costs you more in the long run. 

      Time and effort and your original plants could be ruined if you don't have the right lights. 

      It pays to research the types of lights available and what you need regarding your growing. Set your goals and educate yourself on what you need to get there. 

      It is seldom a good idea to skimp on costs thinking that you will upgrade at a later date when you can afford it. 

      If you don't set up your process correctly from the beginning, you may not have a later date to count on.

      When looking for LED lights, consider the following important information:


      You want your grow lights to be durable. It can be extremely frustrating to have to replace lights a short time after purchase, or in the middle of a grow cycle. 

      A quality LED light should last about ten years. We may be biased, but we believe that a product manufactured in the United States according to high industry standards, is the place to start looking. 

      Four of the five LED grow lights mentioned in this article are made in the United States.

      Brand Name

      When you start looking, you will find numerous brands and manufacturers on the market today. 

      If you are looking at different lights that are comparable, check out the brand. 

      As with most other items, go with a brand that has a good reputation. If you have any difficulties, you want a company that will stand behind its product and provide excellent customer service.

      Energy Efficient

      You will be expecting a lot from your grow lights. They will need to be functioning for at least ten to eleven hours each day. 

      That is a big draw on the amount of energy you will be using. You want a product that will be easy on your electricity bill. 

      Check how many units the light is in total output. Anything less than 300W will cost you. 

      Choose something that is on the higher end of 600W to 800W or more. The higher output will compensate for any wattage loss.


      Because the lights are in constant proximity to your plants, you want to make sure that the lights will not be damaging the plants by the heat that they emit. 

      Another thing to consider is that lights that have a higher heat output will also burn out faster. 

      Semiconductor Chip

      An LED’s light core converts electricity to light and determines the wavelength of that light.

      The chip needs to have at least 3W to be able to provide sufficient illumination.


      What will you be growing? Certain LED lights are made to supply the needs of specific plants. It is not always a one-size-fits-all with LED lights. 

      Depending on the plant, it will need different wavelengths during each growth stage. Tomatoes will require a different type of light than flowers. 

      It is also essential to consider if you are doing just vegetative cycles or if you are doing flowering and growing processes too.


      This is a significant factor. What is the size of the area you will be growing in? As a general rule, you will need 32 watts of actual power per square foot. 

      Again, it depends on the plants that you are growing. Some plants take less light (like lettuce), and others take more (like tomatoes). 

      You will need to determine the amount of light your crops will need.

      Easy to Use

      There may be times when you need to adjust the position of your LED lights. If you get a quality light, it will also be able to be adjusted with ease. 

      Look for lights that have both wavelength and light intensity adjustments. Ease of maintenance is another an important factor. 

      Full Spectrum

      An LED is not just an LED when you want the light to simulate the photosynthesis process. The process requires different wavelengths, as we mentioned earlier. 

      You will want an LED that can deliver the full spectrum needed throughout every stage of the growth process. 

      Some plants need a light in the red and blue range along with the light being infrared and ultraviolet. A quality LED grow light will be able to provide these variations.


      Last but not least, you are going to want a light that has a good warranty. Whatever light you choose should have a decent warranty and even free return shipping. 

      A reputable manufacturer will stand behind its quality built product. 

      In Conclusion

      There are a variety of things to think about when looking at what LED grow light you should purchase. Use the above factors as a guideline when considering what you need.

      If you purchase a quality product, it will cost you upfront, but inferior products always end up costing you more in the long run.

      The Top 5 Fan-less LED Grow Lights 1


      LED grow light technology is still new and rapidly evolving. While LEDs are much more efficient than traditional HPS/HID grow lights, they still output heat.

      To manage this, most LEDs have built-in fans to move the heat away from the diodes and keep them from overheating and getting damaged. While this method of heat management works, it has a few drawbacks.

      First, the fans themselves have a lifespan and can break or be damaged. Every additional component in your light is a potential point of failure. If the fan breaks then it has to be fixed or replaced if you want to continue using the light during your grow.

      Fans also accumulate dust, dirt, and other buildup from your grow room. This means they have to be regularly cleaned in order to operate effectively. Many grow lights don’t account for this in their design and make it difficult or impossible to easily clean the fans. If you’re using one light then this is a minor issue, but if you’ve got more than this can be a huge pain.

      Finally, while most fans are advertised as “silent”, many end up being pretty noisy, which can be annoying.

      Many LED manufacturers are catching on to these issues and some of their latest designs have eliminated the need for fans entirely.

      They do this in a few different ways such as adding much larger heat sinks, opting for newer hyper-efficient low heat output diodes, and increasing the overall surface area of the light to reduce areas of highly concentrated heat.

      On top of not requiring a fan, these lights tend to have a lower overall heat output, run more efficiently, and have a longer lifespan compared to LEDs with internal fans. 

      Here are some of the best options for fanless LED grow lights: 

      1) Spectrum King SK402
