    This light is very strong and has great coverage. I use it for a 4×4 and it more than covers the entire area.

    Arrived way earlier than estimated. Packaged exceptionally well to prevent damage via delivery. And the light delivers way more quality than expected. MarsHydro will no my go-to from now on. Highly recommended.

    Great light but how do I use the daisy chain function on the fc e6500?

    This product is working amazing for our area. It is not adding any extra heat to our room and so far we haven’t ran it at 100% because they’re seedlings about 11 days old

  9. adam – 25/02/2022

    Rated 5 out of 5

    The hinge and the great build quality is A++++ on this light. I will be buying many more of these lights in the future.

  10. Don M. – 14/10/2021

    Rated 5 out of 5

    “Insanely bright. I describe it as sunlight. Really good for wattage, getting the sp3000 for veg tent now
    Update. Plants in 1 gallon pots 11/4
    Transplantes 11/5 in 5 gallons
    11/11 they are exploding with growth under the fc6500! Iv been trying to dial in how much light they need in my 4.5×4.5 grow tent. Iv upped it to the hash mark just under 75% so far at 22 inches from the top of my canopy with no burning.
    All I can say is the light is amazing and worth it over old blurples I was running.
    Update 11/18
    I realize when you hit 75% on the dimmer it jumps to 100% power draw (tested with wattage meter)
    So you can run 100% at 24 inches just fine, atleast I was.
    First day of flower for me. I’m excited to see what it can do!”

    Rated 5 out of 5

    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

  14. Jubal Hays – 10/06/2021

    Rated 5 out of 5

    If you’re serious about your garden and you want one of the absolute best lights on the market then this light is what you’re looking for. Samsung and Osram diodes, white, blue and far red spectrum, removable driver to keep the heat down or keep it on the light to help heat the garden. This light is so good they can barely keep it in stock.

  15. J B – 25/05/2021

    Rated 5 out of 5

    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
