I think I know what could be causing it. This is only hypothetical by the way. I can't even tested yet as I'm still waiting for my LED grow light to arrived. But I built a lot of LED systems in the manner of small systems not grow systems but the electronic project stuff.


I've ordered a 300 watt LED grow light. It states: that it has 100 3 watt LEDs. Now is it going to drive at 300 Watts, probably not. My reasoning for this is that commercial products normally under power their LEDs to favor long life.

The LED grow light I purchased described 50,000 hours before I can expect any of my LEDs to start burning out. So I must conclude when they advertise a 300 watt grow light their advertising the rated wattage of the LEDs themselves as a whole and not actually advertising the actual power output of the onboard drivers.



I'm not sure that they're doing this to favor long life or to save money on the LED drivers, Or maybe even both.

But by all technical standpoints, If my LEDs can handle that power, I'll have no problem opening and up and cranking up the power or modding it. As I only paid $75 for my full spectrum 300 watt LED grow light. And all I have to do is crank up the power and I got a true 300 watt draw LED grow light.

But again, this is all hypothetical. I'll know for sure once I get my LED grow light in the mail. Then I'll start testing on it, and experimenting. :)

Very interested in hearing about this modding that you speak of I just bought the same light.

I am about to grow using the 300 watt mars 1st gen light also, but I modified my fans and took out the glass, i am also suplamenting the light with 2 cree cxa3070 cobs, some would say I am suplamenting the cobs with the mars led,, LOL , I dont think anyone would recomend driving leds at 100 percent, for several reasons really, Ill let the smarter led guys chime in on that one, for me , if I wanted more light and did not want to build a DIY led, I would just buy more m ars housings and hang them side by side, two of the mars 300's would give you 360 true watts of power for only $140 dollars??>>??? thats not to bad really

First time grower here. I started reading this thread after researching if the Mars Hydro lights I picked up are bad or not. I am really excited about what I have read so far, and that the LED's I got are going to rock. I figured I would go ahead and make a post in the thread with my info.

I picked up 2 Mars Hydro Reflector 300w (96*3w) lights. The rest of my setup is as follows:
Space = 30x18x36 Inch grow tent (thinking about getting a 48x48x60 soon since I have both LED's)
Lights = Mars Hydro Reflector 300w (96pcs*3watt),
Medium: Sensi Sci Soil (bottom half) & Sensi Sci Light on top layer
Plants= 3 rooted clones from reputable clone shop in Seattle (Cinex, Sherbet, & Platinum G13).

Here are a couple of pics of my ladies after I put them into their new homes under the LED.
NOTE: I hope the images like this are OK. This is the first time I added any images to a post and I could not figure out the way the OP has them in a nice little box that you can click on to make larger and scroll through. If I need to edit the post and change them no problem-o!

I'm interested to see how they work for ya. I have a couple 1k HID HPS/MH lights and I was thinking about maybe adding a few LED light bars, or possibly a couple of the MARS lights, and some tanning bulbs set to power on for 5 minutes out of every 20 to add spectrum. I was thinking about just experimenting ya know and have been wondering if these were any good as I could have bought a used older model of the same light the other day. Look forward to hearing how they work for you.

This is the reason I bought the 1st gen Mars Hydro without much hesitation, the price point is good and you can cover 4' x20" pretty well with them. I want to remove my glass also. Never thought about the fans, do they go wonky? I am capable of replacing them with badder-asser fans but not sure how much of that sort of thing I want to mess with.
