Heres my assessment of the photospresented
1/ You can clearly see from this pic
that the LEDs are supplimental lighting to what looks like an HPS. The LED light is so weak in comparrison to the yellower lighting and is barely lighting the tops over top of the 'other' lights.
2/ The weed in the corner of this pic
are barely getting any light at all.
3/ In this one...
You get that color with LEDs when its mixed in with another white light as in a multi lit situation.
Same with this pic
4/ Says on the website advertising this light that this 300 watt LED light exceeds the output of 1000 Watt HID grow lights. Whether that is true is something to be tested, I would assume if the lumens per square foot output is better than that of a 1000 watt HPS, there would be no need for two of them in this small hydro set up
5/ Except for the Cree styled LEDS, most standard LEDs from 1mm to 10mm are generally directional. So if the dimensions of this lights is 480 x 314, AND it outputs the same or more than a 1000 watt HPS, then it will only do that covering an area not much more larger than the dimensions of the lamp since 99% of LED intensity is directly in the direction the LED is being aimed.
6/ Its these types of hyped up overstatements that are stunting the growth of LED technology. People are being tricked into purchasing lights that are supposed to pull a rabbit out of the hat in watts per lumen output. While this light will veg very well, and I have had good success with a third of the wattage of LEDs myself in vegging, and while it may output more lumens than an HPS, although I doubt it, saying you can buy one and it cover 50 square foot of grow room space is deceptive. Deceptive in, any light lifted high enough will spread out, hell the standard incandescent 80 watt bulb lights the average room...but one of those lamps will not grow big bud at 50 square foot.
The most truthful pic of all the budding pics, and is typical of any con to have some truth mixed with bullshit, is this one.
Imagine if you will for a moment, the rest of that plant all the way to the floor. One plant, budding at about 2-3 inches below a light thats 40cm x 30cm. Yeah thats about right.
