Mars Hydro 1200w Grow Light

Okay, so I'm sure people have seen my other post about switching out my HID system for LED. I was originally going to get an AdvancedLED 100w to start with, but after some further research I have decided to go with a 1200w Mars Hydro system. I'm well aware of the fact that this brand of LED is nowhere near the capability of the more high-end lights but I'm not out for perfection here.

I'm wondering if anyone has any experience with this exact system that could give me an accurate estimate of how many plants I could grow and how big I could grow them with just one of these lights. I have seen some grow-ops with this specific system and from what I could tell, I can get exactly what I need out of one of these lights, but I need to know for sure before I make the purchase. I am planning to grow a total of 4 plants, but I'm ALSO not growing them to their full potential, or what people around here would likely expect as their full potential. These will be small plants, at their largest, basically only 2ft tall.

**Really not looking for opinions here on other makes and models of other LED systems. I'm specifically interested in the Mars Hydro system and its capabilities only right now.**

I have friends that use the 1600w version. It actually on draws 780+- watts if I remember correctly. This particular light the 1200 only has between 520-600w. That being said you can most definitely grow 4 plants under that wattage. Most people will grow 4-6 plants under a 600 hps easily with good success. The spectrums of the LEDs are fine I wouldn't worry about that. Not to mention thee are countless threads on here about people having good success using these lights. My $.02
