Hello, I am looking into building one of these lights for a 4x4 space and I have landed on 2 types of my stirps for half of the build. I can not decide between the Bridgelux gen 2 or the samsung f series. I am a bit confused with the gen 2 because they are a lot cheaper but it seems like you need so many more of them to have the same output as a f series that it is not worth it. If I intend on running at 1400ma, what do you think is the better decision of strip? How many Bridgelux's would I need to get 600w running at 1400ma and a 46v driver?
