Frequently asked questions

The term 'Full Spectrum' refers to the fact that this grow light covers the entire spectrum of light that plants use for photosynthesis, from the blue light (400-500nm) that is required for the growth of seedlings and green leaves, to the red light (620-730nm) that is responsible for flowering and fruiting. This feature makes the MARS HYDRO FC-E6500 perfect for all stages of plant growth.

The detachable precise lighting of the MARS HYDRO FC-E6500 allows for greater flexibility in the cultivation of plants. Each bar of light can be removed and relituated according to the specific needs of the plants being grown. This kind of fine-tuned lighting can help promote healthier growth and higher yields.

2.8umol/J refers to the efficacy of the grow light. It indicates that the light delivers 2.8 micromoles of photosynthetically active radiation per joule of energy consumed. This is a measure of how efficiently the light converts electrical energy into usable light energy for the plants. The higher this number, the more efficient the light.

Yes, the MARS HYDRO FC-E6500 is designed specifically for commercial plant growth and is perfectly suited for vertical farming. In a vertical farm setup, the space-saving design and detachable precise lighting feature make it ideal for maximizing growth in a controlled environment.

    • Excellent Vivosun alternative! Fast growth & perfect tent compatibility
Size: 3×3(300W)
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. ... show more

    • Good value and does good
Size: 4×4(480W)
It’s been an amazing light. Perfect for veg. Heat is so so but they give you enough wire to run it outside of your tent pretty nicely 10/10 for that. Best value I found at the time for the power and a company I like now. Been running it for months hard with no problems. Have it hooked up to a Vivosun controller and it’s buttery and a much better option than stock. My cannabis plants love this thing in a 5x5 🫪 ❤️ ... show more

    • Excellent grow light, misleading advertising.
Size: 5×5(800W)
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. ... show more

    • FIRE HAZARD - DO NOT PURCHASE THIS LIGHT

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. ... show more
