Well like i said before if you want a good crop from leds you have to pay a lot out in initial outlay.
Power leds for proper growing are 5 watts each and not anything like a normal led that you might think of.
You have to build these units yourself and to be honest unless you really need to shear your electricity usage for reasons of stealth then they are not worth the investment or the hassle of building them.
It takes years to recoup your investment.
Each led is 17 euros about 30 dollars and you will need a lot of them.
If you buy these correct and expensive leds you will have good grow results but it will cost you a lot of money to buy and is hard work to install and build.
Here are the links to where you can buy them if you "need" them,for reasons of stealth as stealth is the only real reason to buy these kind of growing lamps.
Dont be fooled either,these "proper" leds get hot and will need to be cooled just as a hps setup would.
I do not work for any company and do not sell any lights.
This is from my own exp and extensive research.
Using low powered leds and ufos etc will never give you any where near hps/mh results,never,this is the only way to get good led results and it will cost you a lot of money
