Then the 4000k is better to use than the 3500k ?, I am asking because I am ready to order some cxb 3590 3500k cd, and I believe 4000k is better for both vegging and flowering or maybe I am wrong.

Can you do the same but using lens? Or will be the same gains with lens or reflectors? Thanks In Advance.

It will be standalone soil pots and I don't need to know anything else other than the lights as I am looking to use the most efficient lights other than HPS ones. Thanks for your help.

14' x 16' =224 Sq ft 4k = 4000 watts / 224 = 17.8 x sq ft. 6k = 6000 watts / 224 = 26.7 x sq ft. Are you sure that 4k or 6k will cover it? what kind of lights are you talking about?, maybe 6000 watts of CXB 3590 3500k will cover it, I know for sure HPS won't do it, I don't know if CMH will do...

Are these like better than a 1000 watts HPS? or at least will they yield the same. Sun System LEC 630 Light Emitting Ceramic MH Fixture - 240 V w/ 3100 K Lamps. Thanks in Advance.

How many feet are the lights installed from the floor?, Very nice and clean setup. Thanks in advance.

I believe that the way you installed the heat sinks are not correct as you are blocking the channels avoiding the air to flow freely wich will also force the fans making them to work harder, but that just me maybe I am wrong.

Thermal grease, also called thermal paste or thermal compound, is a substance used to promote better heat conduction between two surfaces and is commonly used between a microprocessor and a heatsink .

How many Cobs need to be used to have the same or better of a 1000w hps efficient? And wich ones will you use and what drivers? Thanks in advance.

I believe you misundertood REALSTYLES, he is talking about Digikey and not from where you got the quote.

What is the maximum wattages that one can have out of CXA3070, CXA3590 Cob and also how do you calculate the wattages you will get according to the driver used? Thanks In Advance.
