MARS HYDRO FC-E4800 Smart LED Grow Light 4x4ft Full Spectrum Grow Light Bar with 2646pcs Diodes 480Watt Plant Growing Light Dimmable Commercial Grow Lamp Daisy Chain Detachable,Achieve 2.8 umol/J

I bought a FC 6500 in August of 2021. I liked it. After a year I bought a 2nd FC 6500. During the installation of the 2022 model, the driver for the 2021 model fell, yanking the 120v connection, causing it to sizzle & melt together. I grow in a tent and I like that I can have the drivers outside of it, due to the unwanted heat coming from the drivers. I contacted Mars Hydro and was told no problem, don't worry. They sent me a new cord, adding that if that doesn't fix it, we'll go to the next step. A new cord arrived in a week. The cord is replaced and the light is back on. This is a tuff light! I'm very satisfied, and recommend this light for growing tomatoes and other plants indoors.

I had the light working on low power based on charts but thought I could see it fluctuating. Thought it was me the glasses or something else. It wasn't until I put a watt meter on it I could see the power moving up and down and then realized the thing they call the driver (ballast) that provides the power was way toooo hot for the low power. I then turned it up to see what it would do and would not receive even 700watts. I called the phone number it was just weird answering machine. Then I was instructed by Amazon to email through app. They asked for proof. I sent movies and more emails only to be told after a few days it was normal to be this way. The driver was protecting itself from blowing up that's why I couldn't turn it up it was overheating and is working. I couldn't believe that was my solution. I bought the product one month and 3 days before contacting them. Thank goodness for Amazon help.

Great light just set up and plug in and off we grow

We received this product on time and open the box in my living room to to test it out and I did have a couple friends over and when I turned it on everybody ran for cover because we thought the sun was in our living room giving off solar flares, caught me off-guard and I really didn't expect to be that bright but mostly curiosity because I'm converting from HPS and MH to LED and I am a techno-geek so I have done lots of research before actually pulling the trigger and making a purchase set up literally took less than a minute as far as the hardware goes and all the plugs only plugged into a plug of its own type so you can not do it wrong After hanging the light I was checking out the Heat it put off and I could literally touch the LEDs and hold my hand there and then I put my hand on top of the controller and it was a little warm but I could hold my hand right on top of it and touch it with no problems as long as I wanted I then sealed up the room in monitor the temperature remotely from another room and the room may have gone up over an hour time. Maybe two or three degrees without having to kick on the air conditioner for that room I only just installed it but so far so good I'll come back after a month for an update after I check out how it does with gross

So I have bought a couple of dozen grow lights and influenced the buying decision for a charity that bought in bulk from Mars Hydro. This is a good light that performs well. On this model I actually had a problem with the light and I contacted Mars Hydro. They troubleshooted the light with me and when it could not be fixed replaced it. They only required a small payment for shipping the new light. This light had operated in a harsher environment in a greenhouse than many of my other lights. I have found that the Mars Hydro SP3000 lights are more stable in harsher conditions and none of them have failed. They only required a small payment for shipping the new light! What I like best about this Mars Hydro light is the very even coverage I get over a large area. If you want a light with product support, this is a great choice.
