800watt. Review: 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. Review: 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 Update: Been almost 2yrs and it was on fire at the contection to light bar. Melted connection to wiring harness. Yes there was flames. That google home for fire alarm. Now will post on their warranty service in future.

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!!!!

My light only lasted about 5-7 months or less one grow, I bought 2 of these in the last year or so one is still working fine but the other is not. Edit ... After a few emails mars hydro made it right by sending me a new power box for my light and it works now. I'm very thankful.

*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.
