MarsHydro Reflector LED Grow Light Review – 480W Full Spectrum

By |2018-08-30T21:34:39+00:00March 21st, 2016|LED Grow Lights|18 Comments

Recently we received the MarsHydro Reflector Series Switchable Spectrum Grow Light for our greenhouse. At under $$$* it falls in the ‘budget’ range as far as grow lights go, but that’s not always a bad thing when you’re trying to cut costs. We’ve had a few grow lights go out over the years, so we’re always trying to find a more cost-effective way to handle our problems.

MarsHdyro Reflector Series LED Grow Light Review - Full Spectrum 480W

As soon as the box arrived we noticed it had a fair amount of weight to it, which always sets my mind at ease. Usually, a heavier product means a sturdier product.

The MarsHydro Reflector Series: What’s in the box?

The box comes with pretty much everything you need except the plants – which is a good deal. There weren’t any instructions, but it’s a pretty self-explanatory system as long as you have a general idea what you’re doing. Plug in the power cord, attach the hangers, and plug it into the outlet. We were actually pleasantly surprised at how well-made the included hangers were – we were expecting to have to upgrade those right away.

Our first complaint is the position of the power cord. It’s positioned in such a way that it hangs right in your way if you don’t have it clipped up. Of course, we all know we should be fixing our cords up anyway, but it would be nice if the cord wasn’t right on top – could be one less step for us. Oh well though, it’s not THAT hard to work around. We managed to get it to stay behind the plants for the most part, but I could see it being a little more inconvenient if you were hanging it in the center of a room.

Veg/Bloom switch: How well does it work?

A slightly bigger complaint is that the “flower” setting singed our plants a little bit – which was a little frustrating. We could have probably prevented it by simply paying closer attention, but the lack of an instruction manual wouldn’t help a beginner. This is a budget system, so it’s safe to assume that beginners are going to buy it – the company probably should have included some type of instruction.

The heat off-put by this light wasn’t too bad, on the “veg” setting. There is always some heat put off by any light bulbs, but with LEDs the heat is minimal unless you have it turned up. There is a fan inside to help keep it even cooler, and it still doesn’t eat up the electricity too bad. Our bill didn’t really show a noticeable change since using this light. Of course, we already have quite a few lights running anyway, but I wouldn’t say this one used anything too high.

Summing Up

Overall, this wasn’t a bad light for the price. We could see using it while you’re saving up for something better, or as a back-up in case something happens with your main lights. You should probably do your own research on the side because this basic setup isn’t going to do most of the work for you. For a budget light in a pinch, the MarsHydro Reflector 480W will do just fine.

    I’ve been buying your lights for years .used to love them .wrote you many many times ,so far the only response I got from you is what one word ,thanks, from now on I’m switching to a different brand light ,too bad. I thought you were one of those companies who cared about their customers and their products, good luck. just wish I wouldn’t have wasted thousands of dollars before I found this out

      Hi David, we’re not MarsHydro. This is just a review of one of their lights. Here’s their site:

      They also have a number of social media accounts, which you’ll find links to on the site. If you haven’t been down that route already, that might be worth a try.

      Also, we know MarsHydro folks have visited our site from time to time, so perhaps someone will see this and leave you a reply?

    All I use is MarsHydro for years now… I have 2 Epistar 160 3 of the Reflector 48 (which I started with) and 1 white full spectrum with no switches at all on it.
    I have 2 tents growing Autoflower in 1 tent and Vegging plants in the other.
    I have had no problems, and no burnt out lights.
    I get E-mails from the company every few months asking if things are going well, or if I need any other products, and offering discount codes.
    When I reply, it is only a few hours before they respond, even on weekends…
    They have been great for me, so don’t believe those who may have poor results due to poor gardening, soil, or possibly slamming a good product to get you to look at other products…
    Just sayin…

      Wow thanks for that comment. Of course, everyone has a different take on what they use and some people complain about stuff that other people rave about. Just part of being alive I guess. Nobody’s right and nobody’s wrong.

    I have been using the mars-hydro 300 for the past year (with the 5watt leds, not the 3watt) and I was happy with the results. I needed another bigger light so after careful shopping, and lots of comparing, I went for the mars2 -400watt light. Unfortunately for me the specs on Ebay are a total fabrication and there are no lumen specs on the mars-hydro website. My big warnings are that 1) if you buy from their website direct you will never get your money back no matter what. Check out their return policy and you will see that even if the light comes broken, and you open the box to discover this, then your cash is gone. The second is that the lumen specs out there are contradictory and, though correct info may be floating around, good luck discovering which data set is correct. Mars-hydro, despite their nice website, is really just one more ripp-off chinese LED company like all the rest. Beware! Lies! Lies and more lies!

      I just think youbdont know how to grow. I have a mars reflector 192×5 and 2x 144×5 and they are awesome. Grew frosty ass tight nugs. Practice for a bit and dont blame the lights.

      Ive Used MARSHYDRO for 3 years now. Every time I write them they respond same day. They send me parts for free and give me discount coupons. I don’t know what you did to contact them. Just write a nice email and they will help you.
      PS: the stuff I grow is better than dispensaries TOP SHELF… Using only MarsHydro!!!

    • Marshydro sucks October 18, 2017 at 8:27 pm

      Marshydro does not have a 2 year warranty. My lights are 18 months old and the LED’s are burning out. I called them but it seems that they only cover within the first year. After the first year you have to pay for parts and shipping. What kind of warranty makes you pay for parts within the warranty???? I will never buy another Marshydro product. I have 2 MarsII 900 watts lights and a 300 watt. I will use them until they burn all the way out. Then I will buy a different brand, STAY AWAY FROM MARSHYDRO PRODUCTS. Spread the word. Don’t get stuff with bad lights.

    • Mary Jane Farmer October 18, 2017 at 9:49 pm

      Sorry about your trouble. That seems to be different than the Mars warranty description here which says that they will replace up to 20% of the failing diodes during the second year of the warranty. But thanks for the heads up. This being a company in China makes things more difficult sometimes.
