in this one thread monster indoor i think the dude was using a led light,with great results.

You can see the HPS in the picture, theyre not grown with LEDs.
Now, lets take a looksee at this comment they make.
The new Illuminator SuperPro Series has been designed to add a 3rd Spectrum to the blended mix of light. The original LED Lights combined the Red 610nm with the Blue 430nm.
So what they are saying is the original LED came with an orange LED mixed with a blue one. The orange one is of course, the wrong spectrum for photosynthesis. There is NO SUCH THING AS 610 nanometers Red. 610nm IS orange.
As for the blue spectrum, the 'absorption peaks' of bother chlorophyll a and b in the blue spectrum are between 453nm and 465nm so even their blue spectrum LEDs are not the optimum.
To increase the flowering production, we have added a 612nm Orange to the blend
So here they admit that around the 610 612nm mark is orange not red, its the wrong spectrum for Chlorophyll, so why add more???
and increased the RED wavelength to 660nm.
Their continued use of this line of thinking shows me they do not understand the basics, 101 of nanometer light spectrum. You cannot increase the wave length of red from 610 to 660nm. You are changing the just installing 660nm LEDs which look red.
660nm is a better spectrum for photosynthesis, but the mind boggles why they would even bother leaving any 610nm LEDs on there let alone add in some 612nm ones...
This combination has proved to be far more sucessful than the 1st blended LED Grow Light. The addition has really produced much better results during the flowering stage.
I can tell you right now they have never flowered weed with this light.
3: The Yield.....This is pretty much what it's all about right? well the output of (1) 600W LED Grow Panel is equivalent to (3) 1000W HID Grow Lights.....
There is no such thing as mere 'Output', its lumens per square foot or nothing. The brightest LEDs out there are outputting around 4000 lumens per square foot within the first 13 inches of light from the LED array, great for vegging, under half powered for growing big bud.
They give the dimensions as:
Dimensions - 480 x x314 x 94 mm
In reality, this light will cover an area around 600mm x 800mm with its optimum lumens.
Recommended height (based on 100 sq. ft. coverage):
2-6 feet (adjust as needed)
More fiction. At 2 feet above your plants the 120 degrees angled 1 watt LEDs will cover 2 metres but the lumens will be greatly decreased at the two foot mark. Since there is no plant folliage between 1 inch and 13 inches, then all the potential intense lumens are completely wasted.
At 6 feet above the canopy you will get about a 10 sq metre coverage of very lite intensity LED light. If youre lucky your plants will be getting about 200 lumens per square foot....a little short on lumens considering your plants need 10,000 lumens per square foot to grow big bud.
Again, they have never flowered weed with this light or else they would not be copy and pasting that advertising spin from those Chinese websites that manufacture those lights.
