2025 New Version MARS HYDRO FC-E3000 300Watt LED Grow Light 3X3ft Full Spectrum Grow Light Bar, Smart Dimmable & Integrated Grow Lampe for Veg Bloom Flower, Achieve 2.8 umol/J

I purchased this product 13 months ago. BEST LIGHT EVER ! But the light stopped working suddenly. With simply a hand full of emails and pics sent to prove its condition, I was only charged $20 (shipping fee) for a replacement power supply! In less than 1 week I had my replacement running perfectly again! OUTSTANDING CUSTOMER SERVICE!!!!

I recently added the 2025 version of the MARS HYDRO FC-E3000 (300 Watt) to our setup, and the results have been impressive. While we are long-time fans of other popular brands, this light has proven to be a fantastic, slightly more affordable alternative that doesn’t sacrifice quality. The "Win": Performance & Setup Instant Results: Our plants responded almost immediately. We saw noticeable growth spurts within the first few days of switching to this full-spectrum bar light. Tent Compatibility: It fits and works perfectly inside our Vivosun grow tent. The integration was seamless, making it a great option if you’re looking to mix and match high-quality gear. Build & Packaging: It arrived very well packaged—no bent bars or damaged LEDs. The dimming feature is smooth and easy to adjust for different growth stages. Value for Money Rating: 10/10 At $179.99, you are getting a 300W light with a high PPE (2.8 umol/J) for significantly less than some other "name brands." It feels like a professional-grade light without the professional-grade price tag. The Verdict If you want the power of a bar-style LED grow light but want to save a bit of money compared to Vivosun or other high-end models, this is it. It’s powerful, cool-running, and highly effective. We will definitely consider more Mars Hydro gear for future expansions.

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

Purchased this light in 3/2023. This new FC-E6500 was to replace my lower-wattage Vivosun lights. The FC-E6500 was very bright and had what seemed a promising future. But alas within a few months, the light died; actually it turned out to be the power supply, and the company replaced the power supply. I had several weeks of downtime without a light, and then the new power supply showed up....though this time it had different connectors. I tested the new power supply with the light, and it worked once again. So, with that said, I reinstalled the light in my growing area, and again within a few months, the light stopped working. This time the connector had a burnt prong inside, and even smelled burnt. Note, the light setup had it's own dedicated power, not commingled with other electronics. At this time I requested a full refund and was denied. Instead, they insisted on sending me a new connector, to which I responded with a hard NO, and they said they would send another FC-E6500 but it wasn't new but they denied that it was refurbished. I reverted back to my previous setup with Vivosun lights, though less wattage than the FC-E6500 but much more reliable, and without a product that has potential fire hazard being an issue. At this time I have requested a full refund as this is unacceptable. Update: As of 11/1/2023, the company issued a full refund. I refer to it as "company" as it's not clear if this is actually MARS HYDRO or a licensed retailer, who sells shotty products?? Caution advised.

Wonderful Light, built a little cheap but it works great where it counts. No Setup instructions. so good luck. Put it on a watt meter and it pulls 1001.watts on high.

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.

I absolutely love everything about this light!! The driver installs outside the tent helping reduce temperature inside the grow area. The app and USB adapter work well
