Led lights

Has anyone ever used this light setup before I purchased 2 of them and put them in a 4x4x80 grow tent. My 2 plants are 2 weeks into flower stage after a 9 week veg. I'll try and load a picture. Let me know what you think.

1200w LED Grow Light with Veg&Bloom Switch,GREENGO 3 Chips LED Plant Grow Lamp Full Spectrum with Daisy Chain for Indoor Plants Veg and Flower (LED Grow Light)
Here are a couple more photos 2wks now . I purchased a 600 w sunshine light in the middle look at the stretch on the back plant. Lots of buds popping up.

My .02¢
Currently running 2 2000w Bestva leds. The growth on them is nowhere near comparison with my hps setup. I’ve decided that I’m going to use the LED strictly for clones and Veg. Flower room is 2 1000w hps.

I have used the mars hydro 1200 LED. The efficiency on non-gas discharge LED units is not that good. Expect lower yields for same electrical costs when directly compared to HID.
To gain the efficiency of a HID light at lower operational costs, be prepared to spend over $1000 per light.

I would recommend 4 288 led boards, like those by Atreum or HLG in 3000K.

You can get about 500 actual watts for about $500.
 
I have an auto room I had 6 300 watt full spectrum led lights no matter how many plants I had under them I would get no more than 2 ounces a plant , the same strains grown under a 800 wat led grew 5 ounces a plant the more wattage the bigger the buds , I just bought that 800 watt light from my buddy it was 400 new I got it for 250 with 4 t5 leds added to it it has 2 cobs for veg then separate leds for bloom, anyone wan't some 300 watt leds lol
 
A homemade Led fixture with Vero Cobs produced over a pound of seeded bud with 9 # cobs be driven at 1.5 amps. Very efficient... the whole tent with intake fans and 180 CFM carbon scrubber exhaust plus the 400W led fixture is using around 5 amps..about 35 $ a month for me..
 
This thread really illustrates the challenge most folks have trying to figure out how 'much' light a fixture can provide. Using actual wattage of HID(HPS,MH) lamps as a baseline measurement is useful when comparing the ACTUAL amount of power consumed by a led fixture. The next real challenge is that the efficiency range of diodes used in fixtures varies considerably-that means that for each watt of electricity used, the amount of light produced by a current tech diode can be as much as double as mono-chromatic diodes used in Mars, Bestva, King...et al.
Using power consumed is the easiest metric to compare fixtures-50w/ sq ft for HID and blurple leds, 30 w/ sq ft for current tech cobs, QB or smd's
 
Sorry for the confusion. What I was meaning to say is that gas discharge lights (HPS for example) are the most efficient when compared to cheap LED fixtures.
