MARS HYDRO 2025 New Version FC-E4800 Foldable LED Grow Light 4x4ft Full Spectrum Grow Light Bar 480Watt Plant Growing Light Remote Control

I posted a very long review that didn't get approved, so I'm going to make it short and sweet. This light draws 800w +/- 5% but the driver consumes 70w. So, 730w of LED power is what you're actually putting out. That being said, I have never had happier plants. I went from having an extremely hot tent with a 1,200w HPS to having a 5x5x6.5 tent that never cracks 85°, even with the exhaust fan turned to the minimum. The LED puts out less actual ePPF than my HPS but it's much wider spectrum and MUCH more evenly spread out. My entire tent at 12" doesn't get below 823ePPFD at the minimum. The average at 18" is 1,064ePPFD according to my quantum sensor, and 1,321 ePPFD average at 12". However I like to keep it at 18" so that the light spread it more even, and I don't want to burn my plants as I am not using supplemental CO2. Anyways, the driver thing was explained to me in an email from Mars. I got this grow light on sale for $560, so there's no way I could ever get a better deal on a light like this. My only gripe is that I bought it RIGHT before they put out the FC-E1000w which I would have rather purchased. Oh well, this one is still good for my purposes! If I decide to supplement CO2, I'll lower the light. My power use immediately dropped very significantly just from having this light for 2 weeks out of the power billing period. I'm glad, because power rates in my area are about to go from $0.1205/kWh to $0.24175/kWh at the start of January. I can always lower the light and dim it to cut energy consumption if necessary. I give the light a 5/5 in all categories, but like all companies; MarsHydro overstates the performance of their product. At 12" I only get a total of 1,933 ePPF and they advertise 2,100 PPF Which it seems is never the case in any reviews. As long as you're cool with that, this light grows plants like no fixture I have ever used. The 8 100w blurples from Marshydro that I was using 2016-2019 couldn't get anywhere near this performance or efficiency. Also, the efficiency is much lower than claimed by Marshydro. I get 2.416 EPPF/J. 1933/800=2.416. If we go by the output wattage, I get 2.65ePPF/J, which is less than the efficiency of 2.8 PPD/J that they advertise. All in all, I don't regret my purchase, I will save around $2,000 in the next year on my power bill because of it, and my flowers have never grown so densely and happily. Great job Marshydro, just be more realistic in your ads. Update 1/15/2023: This light has saved me $100 on my power bill compared to a 1200W HPS. My usage statement on November 13 was 1145kWh consumed, December was 13th statement was 1209kWh, This month's statement shows 687kWh consumed. The light will pay for itself in 4 more months. Then we're just saving money.

Nice, small compact light perfect for my tent

Ive had my 800w for 2years now and not 1 diode has burned out and not 1 issue with anything other then a higher then average yeild. I recently purchased 3 Flora Flex 700w crap sniffers and they are good for veg but let me tell you the flowering is nearly half the yeild of my 800w FCE by Mars/ BridgeLux I wish I could send the Flora Flex back for return they are so crappy and theyre hot compared to the FCE800w that I can run 100% and be very perfect temps not exceeding 90° F. I recently purchased the so called 730w FCE 6500 again and the price was great 389.+tax was 419 out the door...the amount of time money I wasted on soul nutrients and electric for the Flora Flex 3 runs back to back was staggering maybe 40-50% yeild reduction Im astonished to say the least. I felt like I was kicked in the family jewels tbh. In conclusion Ive not had any issues with wires or connections getting burned out not that it can't happen but for me Im very pleased with the BridgeLux spectrum for flowering is exceptional.

*scroll down to see my 2 year update* As you can see from the pictures, this light can grow some plants. I use it chiefly for flower and it excels at that. The connection from the driver to the light fixture started to get hot. The whole light went out (right after I harvested, whew!). I contacted Mars Hydro customer service via email. I was helped by Alice, who always responded promptly. They sent me another connector and a video on how to install it myself. After that, the light worked! Great customer service, Alice, and way to stand behind your product Mars Hydro! 2 year update: In May it will be 3 years of owning this light. It is rock solid in performance and is still like brand new. I keep a fan on the driver to prolong the life. The pic is my updated grow under this light along with 2 mars hydro deep red supplementals. Get this light. You won't regret it.

Do not buy!!!!!!! This is the old version with the faulty leds. This isn’t the new one with Samsung leds!!! Also I paid 240 for this crap and now they’re selling them for only 170!!! Yeah exactly. Also I highly recommend farmlite!!! Best value for performance. I paid like 20 bucks less and not only does the farmlite have better ppd, all the leds still work!!! Haven’t even had the mars for a solid year and it needs repair!!!! I treat my gear like it’s my baby, so don’t say user error!! I’ve got vivosun, king led, farmlite, and mars. Mars is the only one that has LEDs out!!! I’ve had the vivosun for 3 and a half years!!! Still works fine. Mars hydro I got it in August 2025. LEDs are already burned out or shorted???? Impossible!!!! Booooo! To mars hydro.

I've had the light 4 days and still can't figure out the app; especially how to set up scenes. The sunrise/sunset function is nice but intensity can't be limited. At 100% a 4 x 4 tent heats up quickly even with the driver mounted outside. So I spent the last 4 days trying to get scenes working but when I set different times with different intensities, the light shuts off instead of increasing intensity. No help can be found on the internet. Anyone know scenes? 10/27/23 UPDATE: After buying this light I bought an Ifresh Inline Fan (DF150-M) directly from MARS HYDRO's website and had software issues adding it to my App. MARS HYDRO support was absolutely awesome helping investigate the fan issue which resolved. So I asked for help with setting up SCENES on this light and was provided a link to a very helpful video. After following that video and setting it up, that is when I encountered the software problem (see previous review) and that is where this got weird. MARS HYDRO asked for my sells receipt and a screenshot of my TIMEZONE setting. I provided bought and promptly received an email telling me that I had to work with Amazon to resolve the problem because I bought this through Amazon. Next day I get another email from MARS HYDRO asking for a bunch more information about my problem with SCENES. So which is it? Never heard from Amazon after MARS HYDRO forwarded my emails directly to their contact at Amazon. I don't care anymore. I've been using the SUNRISE/SUNSET mode and invested in more air conditioning. Problem NOT SOLVED but no longer an issue that I need to spend anymore of my time troubleshooting. I'm leaving my review at 4 because I really like the light! Not so much the software or confusing help.

Best Grow lights on the market in a budget friendly atmosphere!

Works MUCH better than the older style lights from MARS. These run cooler in the tents and our veggies love it.
