Once a Highly satisfied customer, now an unsatified customer
Please don't waste your time with this panel like I did. The 5 star rating is left there to get your attention. A very well marketed piece of junk. I was swayed by the deceptive marketing strategies and paid advertising on all the various grow sites. After owning this panel for a few months I was initially excited because of the nice look and purple lights. Now I understand this panel is NOT worth the money I spent. The case, fans, drivers and heatsinks are the only items of value with this product. I will be using them to build a real light. This panel produces more heat than light. I originally bought it to help with my temperature issues. This panel has been tested by professional who have shown it only produces about 60 watts of light out of 278 watts. The rest is pure heat, and that heat will severely shortened the lifespan of the unit. This has been demonstrated by the myriad of unsatified customers you will not find in these phony reviews. There are much, much more efficient lighting solutions for the same price you will pay for this piece of junk. The LED industry is growing fast. Most of these production panels are an inferior product design for people who will not do their homework or can't afford a more expensive commercial option. For those who don't mind DIY, for $165 you could plug and play build a light engine 5 times as efficient as this piece of crap. Avoid the aggravation and move along. YOU'VE BEEN WARNED...

You may want to select sending in an Amazon box as the senders address says marshydro. That said, upon opening the box I was pleasantly surprised at the heftiness of the unit. The build quality is decent for the price point. I was using an HPS 600 on 12 young plants of various strains and they looked average. The LED light was nowhere near as "bright" visibly but human eyes are not an indicator of light strength for proper photosynthesis. Within a few hours of switching this in and taking the 600 out the plants responded, they had slightly more perkiness. Within days the leaves started to thicken and become slightly more textured, growing rapidly increased. Node spacing was shortened and the plants bushed out quickly. The leaves are about 20 percent larger than previous runs. They started using more water immediately suggesting a faster rate of photosynthesis. The stalks thickened. The LED light puts off the same heat as a 250 watt HPS. Watts are watts when it comes to heat. What makes LEDs cooler is watt per watt they are more efficient at getting the plants usable light and thus require less watts interpreting to less heat. I have to admit, i was very skeptical about LED technology for growing but after trying this light its obvious that its a superior light source watt per watt. The HPS 600 drops off slower at the edges of the grow space though. That is one drawback of the LED. The marshydro600 comfortably supplies a 3X3 footprint with ample light, between the 3rd and 4th foot the light intensity drops off rapidly. However For vegging small plants you could raise the height of the light and easily cover a 6X6 footprint, once the plants are above 12 inches going back to 3X3 will be more efficient to penetrate the thicker canopy. Operation of the light is flawless, the fans are pretty quiet compared to the in-line fan needed to cool a 600 HPS. I still have to test the Yields and quality but if they are on par with HPS or MH, I will be switching out my other 1000w HPS for 2-mars600's :-)

5.0 out of 5 stars Best 600W Grow Lamp
Reviewed in the United States on January 1, 2021

I love the wide spectrum light that the leds in this lamp provide. Great for indoor growing of plants especially hydroponics. Very powerful grow lamps that can be daisy chained. Good quality for the price, I have been using these for over a year now and the brightness and strength have not diminished. Can be used for all stages of plant growth by alternating the height of the lamps to the plants. Great product.

I got this on January 9th so I waited to review it because I wanted to give a honest review. So one garden has had this light for almost two months and I've got to say I'm happy. No its no 600 watt hps but with the hps I needed a 10k btu ac to cool my 2x2x5 with a 600w hps(Jardin dr60) . Although With this light my ac isn't needed. If I had to point out a flaw it's too dam bright for 4 Sq ft. My canna plants are like little bushes at max light height. I've never wanted a plant to stretch out so much in my life. All my clones have rooted and I'm fumbling to met there needs in another area which has been converted into leds also. I don't yet have a gram per watt ratio but I can tell it will meet or exceed my expectations. So for all the haters keep hateing because this light works. This light is cheap and efficient. I've already seen a difference in my electric bill. No joke. It's probably from China but what in America isn't nowadays in USA? Man I gotta tell you I wish I didn't wait so long to convert to leds. If your still weary don't be this light is legit. I can say without a harvest this thing will give at least 1 gram per watt hands down. So 278 grams and not fighting the heat is like a dream come true. I gave it four stars because for me it's still in the testing stages but I don't see anything that wouldn't get it 5 after a harvest. So for every one looking for a cheap efficient led these guys are it. You won't be sorry. Not it's no high end platinum led but it'll keep up for half the cost. I love it so far but time will tell in the end. BUY IT!

5.0 out of 5 stars really good quality light, will get more marshydro lights

Finally have some time to get things sorted, and write this review. Didn’t expect good result before purchasing, but this MarsHydro 600w, is actually a great light! I got some growing tips from marshydro after placing order, really considerate seller. Used the light as following:
Germination-------------24-30inches
Vegetable -- --------18-24 inches
Flower------12-18 inches
Add a pair of marshydro rope hanger to adjust the height, costs less than 4 dollars, really worth to get one. Do not stare at the light while it’s working, or you may get your eyes blinded. It’s really bright purple tint. My plants love it so much, and respond very well, especially blooming. This light obvilously do better job than so-called 1000W led grow light on market, and making nice tight solid buds! Every grower need to get one!

2.0 out of 5 stars Learn from my mistake
Reviewed in the United States on August 21, 2018

This is a pretty mediocre light. There are actually better options for just a little more money. Pulls about 270w. If you were switching from cfls or t5s you might notice a good increase, but really compared to something like an HLG 100 this is bleh. The HLG 100 quantum board will give you as much growth, but only pulls 100w, and costs just $20 more than this, and is not low quality chinese chips. You will easily save the $20 in electricity costs over the life of the lights. The efficiency on this is about .9 μmol/joule and the HLG is 2.2 μmol/joule, more than twice as efficient. 2 HLG 100s would blow this out of the water and still use less power. There is really no comparison. Wish I had gone with all HLG in the first place. (I swear I don't work for them lol just trying to help others learn from my mistakes because this seemed like a great option when I first got in to growing. Electric sky is also a good brand, but about $420 for a 180w setup) GOOD LIGHTS WILL PAY FOR THEMSELVES IN 1 GROW, DON'T BE CHEAP.
