Powerful uniform light distribution, completely customizable light output with a dimmer to suit all stages of growth from seeds to greens this light will do everything you ask of it . I've had this unit for 4 years and its still growing strong. Among the many highlights of this light i could mention by far the removeable ballast + cord length allowing you to remove the ballast and place outside the grow area has to be my favorite. I moved mine up by my exhaust fan so it never gets hotter than barely warm to the touch. which is key for all of us playing mother nature and focusing on dialing in our environment. Mars Hydro has consistently out preformed my expectations for a cost effective commercial light competitor. I used an app of my phone called photone to measure my light intensity it essentially turns your phone into one of those expensive Apogee meters by utilizing your phones forward facing cameras as the light sensor. I was getting measurements close to what the Par map shown by Mars hydro. which is impressive 800-1000 PPFD in my 3x3 12-14 inches from the canopy and i would say about 300-500 ppfd in the outer section 4-6 inches away from the walls of the 3x3 space.

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.

Here I review the 2024 Mars Hydro FC-1500 EVO grow light. In sum, it is a nice light for raising young plants in a small space, and I give it 4.6 stars. I started a new 2.5X2.5 ft. space for raising early phase plants. I looked at a Kind LED grow light but didn't like how I could not separate UV from IR. HLG makes good lights, but the HLG quantum board in question lacks UV and is difficult for attaching supplemental lighting. Only the FC-1500 gave me the potential spectrum flexibility that I wanted in a bar light design, which makes attaching supplemental lighting easier. I was not unhappy to look into a Mars Hydro model. I own an older model Mars Hydro FC-3000, and it has surpassed my expectations for several years. In my experience, AC Infinity makes good tents, fans, and controllers; Vivosun makes the best hangars; but for lighting, you have to take Mars Hydro seriously. The FC-1500 works well for my purposes. It nicely lays down 620 PPFD of balanced PAR light, which over 18 hours results in a DLI of 40. It is also good for germination and seedlings at lower intensities. While it lacks native UV, I can easily attach an outboard UV bar to its frame. And I can buy the Mars Hydro light together with supplemental UV for less than other lights. For those interested, this light works like a champ with the sunrise/sunset function of AC Infinity controllers. The biggest shortcoming of this light would be its 150w relatively low power. I would not use this light for flowering because it is not intense enough. I do not care about that last part, though, for I use it only with young plants in a small space. For this purpose, this light can be recommended.

i bought one of these directly from mars-hydro. i didnt realize the daisy chain feature would require a different type of dimmer switch. i thought it was defective, and contacted their customer service. they responded really quickly. i like the light, so i bought 2 more here. way better than the board lights ive been using. smaller hot spots, the light is more spread out, they have better heat dissipation. ill update if i have issues. edited 5-2-26 i own 4 now. love them.

MARS Hydro makes excellent LED grow lights. This fits my little 2x2 tent perfectly. I added the USB iConnectu to be able to control it through WiFi and program sunrise and sunset simulation.

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.
