I am currently running a cheap 125watt cfl grow, but i found this cheap led light and was wondering if this was any good to run. Its about 75usd

these are the specs:

power: 120W
31cm x 31cm x 3,5cm
1kg
Aluminium
Zilver
amount of leds1365 = 1131 Red and 234 Blue
red: 630nm-660nm
blue: 430nm-450nm
Lumen: 5200-6300
NO IR or UV though

If that's 120w of power consumption, your cfl's are probably just as efficient as that lamp-50 lumens/watt is pretty bad...

Anyone you know using that? Am curious as to its performance.
It says it 4k veg and bloom.
I would imagine that 4k would be better for bloom....no?

4000k is fine for both veg and bloom. I used to use 3500k for both veg and bloom, which is more towards the infrared "bloom" side of the spectrum, while the 4000k is slightly towards the ultraviolet "veg" side of the spectrum.
That QB will rock it through the full grow cycle.
And fuck that red/blue panel. 100% not worth it.

No its not a cfl spectrum, 4k is fairly high in blue from a white phosphor coated led. Its a good all round spectrum.
I don't use that board but use similar ones with the same diodes, here is two plants vegged and flowered under 4k.

I think I will pick up a couple of those to replace my 400watts of T5's(50w x 8 ) in my veg area and see how it does.

Thanks for the input guys!

if i wanted to put say 4 smaller cfl bulbs in there in a circle around the plant, how do I connect them? I found no info on that using google. I know a bit of electrics. So i just get a big cable and connect 4 sockets in parrallel? something like this in one continuous line? (powerplug) ======(socket)====(socket)====(socket)====(socket) = being cable?

sorta like daisy chaining the cfl sockets

I did that long ago a few times. You would wire it live to each live of the sockets, same for neutral and earth.
You can use wagos.

 
thanks man. I have one more question as final about the lumen. Will say, 2 clf bulbs of 9000 lumen equal 18000 lumen in total or will it just be the 9000 lumen in total, as it doesn't work cumulatively

Those would be some big bulbs, wouldn't quite equal 18000 lumens though. It will be somewhere in between 9 and 18k lumens, depending on distance the lights are spread apart, and distance to the plant.

Ya, if 1 puts out 9000lm then 2 put out 18000lm.

What @HazednConfused is talking about is how many photons will reach your canopy. When they give lumens/wt they are giving lumens @ 1ft away from the bulb when it's on. The amount of light that reaches your canopy is dependent on more factors than just how much light the bulb produces. The amount of light at canopy is dependent on distsnce to light, the fixture the light is in, the surrounding walls reflective properties ect. So you can change your amount of light at the canopy (also called PPFD) without changing your bulb or source of light, and so when calculating your light needs, it's important to know how your area or fixture will effect your PPFD. Ultimatelty though, the lumens or photons in individual luminaires are added when calculating total light quantity produced. What actually hits canopy is variable and can be manipulated, but cannot be simply added, and is a different measurement than the total quantity of light produced.
