Out of all the grow lights in the market, the mars hydro FCE-4800 is one of the best grow lights I’ve used. A section of this light died on me. I emailed mars hydro and within two weeks I received a bar replacement. Thank you, Mars Hydro for the excellent customer service. You have a loyal customer for life.
New Review:
My dimmer box was broken I had to get a replacement.
I was upset I spent so much money and had problems out of the box but its fixed now.
Probably a rare thing. Caused a costly disaster in my grow at first. I was pretty angry.
Here’s the good news though!
Onto the LED light itself:
This is a powerhouse so be careful with it. Unless you have your growing environment dialed in 100% or close to it you will need c02. Also ignore the direction manual about spacing from plant top to light fixture distance. This thing puts out more par than the advertisements specs state. You will need to experiment with how far you keep this thing from your plants because its like a planet in a tent shooting out sun beams basically. IGNORE the directions about spacing from plants. Find your own sweet spot by watching your leaves.
It’s not a bad thing to have more light than you need but you need to adjust accordingly to this. I keep my lights WAY farther away than directed. Don’t mount the driver on the light, keep that with its own fan pointed at it outside of your tent or on the floor in your grow room with a fan pointed at it. It’s gets pretty hot and its all of the weight on this light. Without it, the bars themselves are very light and no stress on your tent or hanging fixtures.
I don’t suggest this light for a 4×4 unless you really know your stuff and can keep good control over your conditions. I would say people who want to try a powerful LED like this should aim for a 5×5 tent. Saying this out of experience with using this light.
I would suggest it to beginners wanting something strong and veteran growers just be mindful you are a getting a really powerful light and you need to be ready for it. If this is your first LED from old school traditional grow lights you will hit a learning curve with it so hang in there and stick it out.
If you are in an actual grow room go for it, if you are a tent grower prepare yourself for the power you will have to adapt to it. Again, get a 5×5 tent unless you know what you are doing in a 4×4
If you are growing in a smaller space tinker around with 50% and 75% on the dimmer. You really need to be ready to use this thing at full 100% power. So unless you are ready for the power behind this thing I would get a different LED that is less actual watts. If you are ready for a light like this I think the powerful even spread of light and coverage area will give you really great results.
Assembled this LED fits in a 4×4 perfectly with very very little space between the tent walls. It is almost exactly 4×4 feet all said and done. This thing kicks out like the sun in the summer.
This is an excellent light, worth the money. Want to buy another one
This literally touches all the corners in a 4×4. Perfect for even coverage. Incredibly bright as well, I really don’t find a need to go above 60-70% power, but it’s rated for a 5×5 I think. The driver is passively cooled, but even at 60% power was barely warm. Not only reduced my temps inside the tent, but now I barely even run my window A/C to cool the entire room. I now have a new problem: humidity due to the lower temps. Went from 50-55 to 70-80. T5s were almost perfect.
No tools needed to setup, but you may want an extra pair of hands as it’s kinda big. Don’t make my mistake of replacing the lights mid-grow with a tent pull of plants in a trellis net.
Easy to assemble, works great, and if you’re worried about the diodes being bridgelux and not Samsung. Don’t they are just as good, no real difference
Great Light i absolutely love it!! The light also just barely fits in a 2×2 tent very tight fit tho. I highly recommend this light no problems so far.
The main reason I decided to go with this light was because of the price. I really couldn’t pass up a 300w light under $250. I think it’s a fantastic light for a new grower with great performance.
I was curious if it would fit inside my 27″x27″ tent and it did without issues. It was probably overkill though so I ended up putting it in my 3×3 tent instead. The LED driver is removable which is fantastic because it allows you to place it outside the tent in a cooler environment. The box was a beautifully plain nondescript brown, and packaged well.
Light was exactly what I was looking for. Easy to assemble. Fit perfect in 44!!!
The light is fantastic but the assembly instructions included were completely wrong. Search youtube for assembly instructions if you need help.
Upgraded my set up from the other style mars hydro, these lights are much cooler in tent. So far so good, just vegged so fa
My first led grow light and so far no complaints
Tried this in a 3×3 indoor flower garden probably better for a 4×4 as you’d have a little more area around the perimeter for fan lines and other tidbits. It didn’t effect mine at all but it was tight. It fills the area corner to corner. The flowers turned out dense and enormous. The most surprising thing was the size and density of the lower flowers under the canopy. I’m not talking about the lower third larf that won’t get touched regardless. I pruned that trash off. I also love the fact that you can station the driver outside of the tent for temperature control. I’m am very happy so far with the price and the results. I got this unit with a coupon for like $100 off.
The light seems very sturdy and well made. The only issue I had was the dimmer. Always seems to be such a cheap switch on otherwise great lights from Mars Hydro. First light had to be exchanged for one that worked. Amazon made it right quickly though with a replacement light sent immediately. Have had this issue before on different model lights from the same manufacturer. The new driver and dimmer worked beautifully and the light can go from 0 to 100% power. Do love the low heat output, especially with the driver mounted up high in the exhaust fan air stream. Getting well over 1000 par readings at 10 inches from the canopy. Buds responded well to the new light. Looking forward to using on a full run seed to flower. Ill update the review in a few months after and show the results. Coverage is perfect for my 4×4 closet. Also, do make sure to alternate between A and B bars when assembling the light. They only have one UV led diode per bar. A and B bars have them at opposite ends for even coverage.
It’s a good light! Easy to set up and use, it doesn’t make our flowers hot, puts out way more than enough light. We had an area to review a timer that’s supposed to be with it? There isn’t one. We bought one from Walmart and it works well with it! Power bill hasn’t gone up much either. Highly recommend!
Been running this through several harvests now & I can honestly say the light output & par readings are amazing. My most recent grows haven’t looked better. Just wish customer service was a little better with Mars Hydro, in reference to another product.
WE switched from another brand to try this particular light. We are so glad we did. This light is like the true sun it seems to our plants, To try this out we put 6 scraggy plants we were gonna cull in under this light to see what would happen and wow. Glad we didnt cull them and can not wait to get our veg plants under these lights for the turn! OH man. We have a 4X8 new tent with room for 2. We shall get another when we can! Bravo Mars Hydro.. Wow!
I made the mistake of thinking this had the same PAR as the FC folding model. It doesn’t So I had it dimmed and farther away then it needed to be. So you pay less and the only compromise is this light needs to be a few inches closer to achieve the same par as the FCE. However both lights use the same wattage. Inside a tent being far away doesn’t have any advantage. Half dozen one six of the other.
The light is good in a 4×4 not to hot, able to keep the dimmer and power box outside of the tent to regulate the temp. Solid buy. If you’re expecting to receive the mars hydro sticker’s they didn’t ship with my order, but that’s not really a big deal to me
Qualitative Lampe mit einfacher Montage. Die Hitzeentwicklung der Netzteils ist unter voller Auslastung ist gut. Das Netzteil kann sehr einfach auf der Lampe angebracht werden, wer sich allerdings das Gewicht sparen will kann es auch einfach wo anders montieren da die Kabel eine gute lnge haben.
Nun zur Ausleuchtung die wirklich gut ist. Das Licht strahlt gleichmig, sodass gleichmiges Pflanzenwachstum gewhrleistet ist.
Wer in dieser Preisklasse sucht wird hier fndig.
I love this light series. It was bit bright for my persimmons at full strength, hazels too; so I used dimmer switch to turn it down. Now they are very happy. I love the light, plants do too. Produces nice tight nodes on tomatoe seedlings.
I love how it’s wall to wall coverage. There’s nothing I dislike about this light. Fits perfect in a 3×3 te
My buddy had one of these just setting in the corner so I brought it from once I put it up in my 1st 4×4 grow tent I knew I had to have a second everything so I bought another 4×4 setup just for these lights I’m in love
Retired my old de has andwas skeptical this would perform on PAR . I’m pleased to say this is an upgrade over that 1000w light. Doing this run full power ar 24in and loving results. Great light distribution and in a tent it’s amazing. I have a spider farmer light that is not bars and when ballast burned out I was in trouble. With this, if bar or ballast go bad I can fix things easily. Bars also make for great light spread and cooling. Way less heat than hps and way more light for less electricity. This is a top notch light and can’t wait to get anothe
Super easy to put together and use. Dimmer function is great to. I have never been a fan of the brand until I seen a friend’s grow using this light. I measured all of the metrics in real life and wow! I have replaced a Fluence Spyder v2 with this and will be replacing 2 more. Don’t forget to click helpful! Runs around 82 at 14″ and my Glue is using a lot more food in my perpetual. Been running the same strain for over a year and this was best yield/terps yet. Just had to up my EC. Great buy
Wow, what a light. Coming from Electric Sky’s I was was skeptical, but these things are noticeable brighter and results are proof alone
Initial high cost but did the math and it will pay for itself compared to hps system in 2yrs of daily use. It uses half the electricity as a hps system for the same size coverage. Also has more even distribution of light over given area as multiple sources vs single hps bulb. Also hps is notorious for high heat output, you can’t even touch it but the LED is only warm to touch. No need for cooling in grow area. Definitely a better overall system. However after buying a second light and close inspection of driver, it is labelled as 730 watts not the advertised 800 watts. Now it makes sense that i couldn’t get the higher advertised par map with my systems fc-e8000. Still a good light but fake advertisement that reflects poorly on the company. See photo
I purchased my first FC-E4800 in 2021, it has been an outstanding light and continues to operate just as well as it did when I bought it, so I got 2 more! The power rating has been consistent throughout all 3 lights, I’ll include a picture of my energy meter, but two of the lights are pushing 973 watts. I haven’t had burnt out Diodes, and the dimmer is variable so I get to set my power exactly where I want it, other high end lights have steps in power. I haven’t had issues with any cords coming loose, and there hasn’t been any defects to the workmanship of the 3 I have.
Below are some of the updates to the FC-E series lights I have noticed.
They did change the dimmer box, it is still built with a variable dial, and they changed it from two buttons to one, but the function is The same
The driver support brackets were changed from metal to plastic, mostly to reduce the cost of manufacturing in turn making cost-effective products for customers. From my experience it protects the heatsinks on the lights when the brackets are installed, and if you need to shift the position of the driver or remove it.
The output wire was changed from 4 cores to 2 cores to reduce the probability of poor contact and with the change in the dimmer box, the extra wires were unnecessary.
the price has also been reduced a lot, I paid over 570 dollars on my first one.
Customer Service:
Mars Hydro has unparalleled customer service, when I first noticed changes to the lights, they assisted me through everything! They honor their warranty on their lights and they ship very quickly with the lights arriving 2-3 days, they have US based warehouses.
I highly recommend this light manufacturer, 5 stars!
Its a big light that shine bright even when your not using it on full light! Im using mines on half and it still lights up the majority of my basement! I bought a 480 watt 4×4 first and was happy with it but since Ive bought 680 watt 5×5 i wish i would of it first because it makes the 480 watt looks small! I will be buying another another 680 watt very soon! My plants are loving i
Mars Hydro just keeps getting better. LOVE that they listen to growers (who here remembers before they had the dials?! LOL) and keep updating and upgrading with every release. The FC-E8000 is no different. It actually supersedes what Mars Hydro says the light’s wattage is. It says 800 watts. My meter read 825. So. . .MORE POWER! It’s has a huge driver, is cooler than their quantum board type lights. Even had to adjust my inline fan controller. Made that much of a difference. Can’t want to see how this thing performs.
I own a fluence Spyder, growers choice 720, hlg600 red sped, platinum p9, de hps, and a couple others different light and I must say this light is definitely my favorite. Extremely light weight, and easy to assemble. The biggest thing for me is how well the plants respond, getting a solid 18+ inches of penetration into the canopy with minimal light stress and extremely high quality finished product.
We started out with a 250 light and went up to the 480 to yield more flower and we’ve definitely got more flower so we are definitely happy
Light is sturdy and easy enough to put together. It should probably come with 4 rope racket straps instead of 2. Box was missing parts, which is why it gets 4 stars. Missing the wire leaders that attached to wye bolts and for some reason I didn’t get the coveted Mars Hydro stickers that I was looking forward to.
Well worth the money, easily blowing out other older models in every aspect I can see. Even side by side with a TSW3000 it dosent compare.
Packaged well, easy installation, huge savings on my electric bill. Very happy with this purchase. My plants love it.
Arrived really quick. It came packaged in styrofoam and a box inside a box so there was no damage at all. After assembly, I was surprised at how sturdy it was. Man is it bright! Working beautiful! Do not hesitate to get this. The price is more than worth the it!
I am so pleased with my fc-e 3000 I have another one on order for 1m x1m tent In the future as I replace lights it will be with mars hydro. Keep up the good standard thanks
Also die Lampe kam recht schnell und heile bei mir an. Aufgebaut war sie auch recht schnell und unkompliziert. Man braucht fast keine Anleitung dazu. Meine Kruter wie Petersilie und Maggi Kraut lieben diese Lampe, die wachsen brutal schnell und haben ein echt schnes Grn. Ich bin sehr zufrieden mir dieser Lampe. ber Langlebigkeit kann ich leider noch nix sagen, hab aber da wirklich keine Bedenken! Also klare Kaufempfehlung..
I bought two FC-E4800 as upgrades to my HPS 600w fixtures that I had to supplement with small LED 32watt GE bulbs. No contest. The MARS fixture is hands down the better light and surprisingly it is even cheaper than buying the Predator reflector, HPS bulb, and digital ballast to run it.
When configuring it I am not the most technical and had to reach out to Customer Service—they were amazing. Super responsive and walked me through the solution in a matter of minutes. I felt pretty dumb once I saw what I was doing wrong.
This light is a game changer for indoor gardening, and after seeing it in action, I see no reason for people to spend extra money on HLG or Spider Farms, let alone big money lights like Scynce or others “premier” brands. Buy with confidence and truly enhance your garden!
This light is fantastic. The light output is perfect for a 4×4 tent. The heat produced is minimal. The highest temperature I’ve read so far is 86. The price point for the output doesn’t get much better. If you are new to growing and aren’t sure about what to spend money on spends it on a good light. Happy growing.
I have been using Marshydro for awhile now.. I upgraded from the TSA series to this one and I absolutely love it. Great coverage, had amazing results under this loght.
Nice coverage area (bar-type lights are definitely the way to go!) I’m unfamiliar with the the brand of diodes so time will tell. I still prefer my Hyphotonflux lights with Samsung 301B diodes and Meanwell drivers. Who knows, perhaps this light will change my mind. I’ll post an update late
Not gonna lie at first I was threw off by the fact there was absolutely no instructions on how to assemble the light. You’ll swear at first all the pieces aren’t there. But I figured it out and it honestly only took me 20 min from frustration to finish. I’ve run almost all other marshydro lights and these by far are the most impressive. They almost let off no heat and you can have them incredibly close to your plants without worry of burning them. So far I think its been a great light for the money. Considering I have a Nextlight Mega in the tent next to it and my light meter says the marshydro is brighter. Though that may be dew to age difference being the Mars is much newer.
I put the driver outside the tent, have a filter on the inside of the tent and the outside of the tent for air going out. I have a filter on the outside of the tent for air coming in. The oscillating fans are set on low do to the lack of heat. Dialed down the intake fan for equal air pressure. This is my first time using a tent and LED lights. My girls are Wedding Cake. Will update in a couple of months just before harvesting.
I absolutely love this light. I have it set up in a 3 x 3 tent. It’s so easy to set up and it feels like a high end top quality light
If there’s ever a value for money light it’s this one. And you just can not go wrong with A Mars Hydro product. I have always used their lights and tents and they are by far best quality for your money.
Great customer care and next day delivery. I love it and highly recommend this to any home growe
Works great. Got one in a 4×4 and one in a 3×3. This light does well in both tents.
Very high quality
Room temps r perfect with this and the plants r thriving
Loving this light so far good coverage & the bud is Rock solid!
This light is awesome! So bright and nice spectrum! Perfect for 3×3 grow space
The great things about that product are the low cost of operation along with the low heat output.
Have only been using the light a few weeks very happy with the growth so far. I am very excited too see it into the flowe
It’s actually perfect for a tent and adaptable to anywhere really. It’s made with the best technology too just check google and you’ll see plus Ino there’s a Ssomething 3000 that’s the exact same as this but 30 more expensive
Its being used in a grow tent. It fits well and provides the necessary light for the job.
Absolutely love the fixture. It is very comparable to the original FC6500, as I have both. Mars Hydro has come a very long way towards competing with the upper echelon of grow light manufacturers. If I had to critique one shortcoming it would be their customer support. Although the cord leading from the driver to the light is indeed exceptional in length for placement outside a grow tent I wanted an extension of some sort to mount it outside my room in an accessible convenient location. It’s unfortunately been a long and arduous journey communicating with them through email to continually hear them inform me that there’s NO way for me to purchase an extension from them. Love the light…..completely unsatisfied with their ability to satisfy my requests AFTER my purchase
Love this light. Mars hydro has come a long way and makes some of the most innovative, high quality lights for a good price. I’ve used many different brands before but I’ll be using mars hydro for all my future light, tent, and fan purchases
Just bought this light for my 3 by 3. I know it’s over kill but I love how easy it was to put it together. I also like how the driver is detachable to reduce heat in the grow tent. Its seem extremely bright for 450 watts. I’ll give a update after I’ve put it to use. An really sturdy.
Had the 1000w small TS light which did me ok for a minute.. Than when i got this light i see an amazing output and more uniform grow.. 1st picture is when i added the light and 2nd one is the results 2 wks later.. love this light and i will be getting more of theae for sure..
Aside from the lights being lit af, Mars Hydro customer service and Janet are killing the game. I’ve had the e4800 fixture for a good minute now and have had a few problems, such as not getting the connectors to lock together or shorting a light bar. Every time time I contact Mars Hydro, Janet ALWAYS has a solution. She’s literally sent me a locking m-16 adapter to practice getting the clasp to lock and yes I spent an hour or two trying to get it right before contacting customer service. I recently had my light malfunction and the warranty was completely honored, COMPLETELY. I’ve seen stories of bad service on Reddit but let me tell you, Mars Hydro delivers.
Bought the FCE-3000 for $364.99 CAD 3 days ago. It originally was 19% off of $478.00 plus a $25 voupon…. now $389.00 is non sale price? Stange…..This is less than I bought the TSW2000 for last fall.
It arrived last night. Took me about 20 minutes to assemble and another 20 to remove the TSW2000 and hand the FCE-3000 in the 3x3x6.
The design is great, very minimal and Very light weight. Seems quite bright, but no real difference to the TSW2000 in that regard. Checking the draw, it’s only pulling 275 watts, not the 300 ~5% as advertised, and when I adjust the dimmer, it steps intensity (almost blinking) where as my TSW1000 & TSW2000 are smooth. Going to contact the seller and inquire as I think there might be a problem with the driver.
It really would benefit from a step by step instruction. There were parts that were not mentioned but needed. I was in a out building with no internet so I just figured it out. I had to take it apart a couple of times. The wiring is extremely heavy duty and I have not figured a good way to store it. I could mount the electronics remotelt toremove the source of heat, for now, Its attached to the light. Its plenty bright the dimmer works after figuring out the right combination of switches, I could turn it off.
I left my original review below in parentheses for context, after my initial poor review the seller contacted me very quickly and we emailed a couple times back-and-forth all within 24 hours I was provided with all the information I needed, very pleased with the service from the seller. *original review* (The light seems high quality, and is very bright for the wattage. My review is based on the fact that there is almost no information about operation and assembly. The assembly instructions for this 600$ light that comes in 12 main pieces with about 35-40 small parts are one side of one page (4 pictures really) and dont include any information or pictures of how to attatch the wire hangers. (Included photo) Thats all you get. I got more instructions with a 40 dollar Lego set. I had to search YouTube for a how-to video from another consumer. They list hanging height for diff stages but not intensity, and theres no par map! Am I supposed to blast little seedlings at full power only 6 inches further than when they are in full veg stage? I was excited about the versatility of the dimmer and innovative adjustable bars, but it will be difficult for me to get the full potential of the light or my plants with no information. For such a technologically advanced and versatile light the manual is stone age.)
Upgraded my 4×4 from a TSW 2000 to an
FC-E4800 and moved the TSW 2000 in a 3×3, had side by side comparison for 3-4 weeks and i can tell you the 2000 performed as good as the fc-e 4800!? The light worked great but just couldn’t see a noticeable difference. So…I got a more expensive FC 4800 (OG model with Samsung lm301b) despite beeing the older model and returned the cheaper FC-E model with Bridgelux chips.
The FC 4800 was a warehouse deal, had a slight defect but nothing major, originally wanted to return/exchange it so i was thrilled when i found a smoking deal on a brand new unit (fc 4800). Ordered it got here quick but…not the same light bars anymore. As you can see on the pictures the one on the right is the OG fc 4800 unit, the one on the left has the FC-E light bars on it with the Bridgelux led’s. They were fixed, not adjustable ( as expected) and came with a Moso driver, the OG warehouse deal came with an Inventronics driver. I decided to keep my slightly defective light and returned the new ‘fake’ one. Amazon reimbursed me the difference in price of the two! Awesome customer service on their part.
Next is an update on the TSW 2000. Worked great for 2 and half months then suddenly…. I’m standing in front of the tent and i can see flashes through the zipper?!? This one baffles me a great deal, the light was flickering in and out full power and it’s switched off!! Wth is going on here?
Usually light is plugged in the timer so wouldn’t happen when everything was live but if your turning your lights on and off manually it’s definitely an issue not to mention the potential risks involved with something electric going on and off when it’s not supposed to. Crazy
Moral of the story:
Be very cautious of what’s advertised and what you get these days, Mars Hydro offers great deals on what seems to be a fairly good product, looks good, works good for a while but at the end of the day just doesn’t cut it. I did get in touch with their customer service at first or they got in touch with me i should say after posting a bad review an initiating a return (yes another one) on a 4in fan that sounded like a jet engine…we’ll skip that one for now. They’ll work with you to a certain extent as long as you fix your reviews.
Let me be clear here, i have reached a satisfactory conclusion (refund) to all my issues but not without a lot of stress and anxiety, that certainty was the most painful experience I’ve had with a vendor on this platform period. Can’t say you were never warned!
Thanks for reading
Now get back to your coffee and keep shopping:)
This light is awesome!!! I just did a full grow with the FC3000 and it did great in my 4×4 tent. Now I have the FC-E4800 and it’s a HUGE UPGRADE to my garden!!! I couldn’t be happier!! It runs nice and cool with the bar setup and pulls exactly what it says, 480 WATTS!!! Super bright and a tons of coverage!! Don’t hesitate to buy this Light or any FC series!! They are awesome grow lights!!!
